Subaru WRX turbo uprade w/ Perrin V2 Fuel Rails

Hey guys this is my 2003 WRX and I have done some pretty big upgrades on it and I am just trying to show what all I did on it and if you have any questions feel free to ask. Parts list:
Injen Short Ram Intake
Blouch TD06 18G Turbo Internal Wastegate Ceramic Coated hotside (Courtesy of Tanner @ www.rallysportdirect.com call him and he will take great care of you)
JDM Large TMIC (20x11.5x4.5) 3 times the capacity of an STi Intercooler.
JDM 4 into 1 Ceramic Coated header and flex pipe (cheap ebay part with GREAT quality)
Quick Time Performance Downpipe with Electric Cut out to OEM Mid pipe and Stock exhaust from there back. (cut out open this car sounds AMAZING!!!!!)
Fuel System Upgrade:
Perrin V2 Fuel Rails (these are incredible! Great fit and amazing flow I absolutely recommend these rails)
DW 650CC Injectors
Walbro 255lph fuel pump
According to the pro-tuner I took my car to this system with the fuel rails can support up to 450whp before I need to change the injectors which is CRAZY.
Also I have the AEM UEGO Wideband AFR Gauge with the AEM Oil Temp AEM Oil Pressure (awaiting adapter for install) and AEM EGT Analog Gauge.
Let me know if you have any questions regarding the install or anything I will be uploading the rest of the videos showing the install process of my upgrades but I am sure those won't cover everything. I did all of the work myself in less than 2 weeks in my garage so trust me I can answer your questions lol.

[@scoobiewrx]

The pair of you are so easy to wind up. I could do this all day ;O)

[@rextuner03]

Thanks man. Yeah I have since moved it, its much better now.

[@gnzlzjosable]

Sick subby!

[@thediscman6996]

Plus one for ebay headers!! I have some on mine as well.

[@NatashaB]

Nice car man, good to see you're still trucking with a new subie. Any more mods to come or are you done here?

[@raudelraigoza9629]

Awsome love it

[@rextuner03]

No I dont have stock internals anymore. I ran them for over a year with 346whp and 326tq with no problems. I just wanted more power so I built a 2.5 hybrid. The usdm 2.0 is a little under rated. With a good tune running methanol they are a solid performer.

[@rextuner03]

@TheBeerBox80 Thanks man. It's changed a little since then though I have added an APS DR 525 FMIC and meth injection and 1-4 PPG Straight Cut gears full billet syncro's and shift forks the whole 9 yards. I got it dyno'd the other day and it made 345whp 311wtq on the USDM 2.0 and it runs like a champ. For these 2.0's it's all about the tune.

[@scoobiewrx]

I've got a TD05 20G making 22psi and i'm still using the stock air bypass valve through a stock STi intercooler which is plenty good up to c.420bhp. You will have to go to a decent front mount to better the STi intercooler as many larger topmounts are less efficient even though bigger. Size isn't everything ;o) Ceramic coating your headers/exhaust is the right way to go but it's more to do with keeping heat in the exhaust to promote faster turbo spoolup.

[@siriansight]

expected not much got an awesome little look nice man keep us updated

[@rextuner03]

Thanks man, I don't have the car anymore unfortunately. Got married and had kids and what not and had to get rid of the toy..... I miss it so much lol.

[@siriansight]

hhaahaha cool best wishes with your little ones !

[@rextuner03]

Ben Featherstone Thanks man.

[@NatashaB]

@rextuner03 That sounds about right on the TD06 18G... It's a good turbo and from what I've seen, reliable. I've seen cars pushing (although barely) up to 430~ out of them. Hope your build goes well.

[@rextuner03]

@cheukchan Yes you can use your stock ECU you just need an open source tune application on a laptop with an OBD2 connector like the Cobb AP uses. I spent $175 on the protune and my car runs great. Depending on whether you have any protuners in your area will make the difference on whether you should get the cobb ap or not. What mods do you have and what year wrx/sti?

[@rextuner03]

@LouisBurleson There is a little dock that you attach to the intake and run it though there. It's the main supply to the engine so you can see it running in but I didn't highlight it in this vid. These fuel rails are good but they are a bitch to install lol.

[@TheBeerBox80]

@rextuner03 That is the problem with modern cars, the check engine light comes on for any thing :). I like your setup.

[@damansti]

You better chech that chech engine man and its nice how much power does it have and have you took it to the track yet

[@rextuner03]

@scoobiewrx Since this vid I have gotten my car completely tuned and idles much better. My car was running on low boost mode and having no problems running lean or anything. When I drive I vary between 12:1 to 14:1 which ideal when under boost. And as far as running the stock air box that is your choice if you want to run that. Granted it's not a big hp gain but I didn't pay much for it so it's all good. I know enough about my car that it definately won't go "pop" by any means.

[@rextuner03]

@elemento1991 Mine is working just fine and it's been over a year. I have another sensor laying around just in case I need to replace it. According to the instructions from AEM it should be placed 8 to 16 inches away from the turbo which mine is right around 8-9 inches away so it should be good.

[@rextuner03]

@EdSabbath Yeah a full motor build 2.5L Hybrid with Kelford 272 cams all forged internals and I am not sure on the turbo yet. According to Blouch the TD06 18G 8cm turbo can support 400whp so I will probably just stick with that when I do my build.

[@rextuner03]

@TheBeerBox80 My passenger side tumbler valve wasn't plugged in all the way so it threw a check engine light. Took me forever to figure out what it was lol, but I got it now so it's all good.

[@rextuner03]

@tegagsr it is a really nice turbo! It dhs spool a but late though, I got it knowing I would go with a built 2.5eventually. So for the 2.0 I would stick with a big 16G or smaller, I don't get boost until around 4k rpm so unless you want all to end then I would stick with something a little smaller. Fuel rails are a must if you want to keep cylinder #3 from leaning out. You can use the stock ones but it's a gamble

[@rextuner03]

@scoobiewrx Actually I have done quite a bit of tuning on these cars for years. I have seen WRX's with 800hp run the same bypass valve and have had no problems at all just like me. I haven't had any problems with anything that I have done and I have some mods that weren't entirely needed at this point in preparation for future mods. I know I didn't HAVE to do the fuel rails and stuff but I did it just for the simple reason that i was in there so I should get it done so I don't need to later.

[@scoobiewrx]

To properly keep underbonnet temps down you need a proper heatshield that completely covers the turbo, generally made with flexible reflecting material and thick fireproof backing. I'd be more worried about your internals going pop than your gearbox or clutch. It sounds like you either have a tactrix cable and you've flashed your ECU with a ROM someone has sent you or that you've downloaded, not a full custom roadtune done specifically for your car.

[@benjamingomez5362]

can you upload a video showing where the water line coming from the turbo ,,connects to the head or where else .l think its call banjo bolt that has at the end to be connected thank you

[@rextuner03]

@damansti Yeah the check engine was part of the fuel system there was an EVAP line that wasn't on all the way. Reset and it was fine, the car has even more done now. FMIC and meth injection with new engine managment. The car on the factory internal 2.0L I am making 360whp and 311wtq :) it is running so well it's crazy!

[@rextuner03]

@ty922 Well for one I wanted to try and keep it a sleeper and a front mount is a dead give away. And cost was another motivator. And then the front mounts as you probably know increase turbo lag and they don't gain much more hp than a good top mount and a hood scoop. This intercooler has about the same efficiency as a lot of front mounts unless you go to the massive ones lol. I am very happy with the performance! I ran a 12.0 @ 114 the other day and that was with my clutch slipping.

[@rextuner03]

@EdSabbath Yeah I am not sure exactly what power I will be making when it's all said and done with the methanol injection and the cams and what not. So I guess we will see lol.

[@rextuner03]

@cheukchan 300-320whp is pushing it for a 16G turbo. I would go with the Big 16G if you are set on getting one of those. It can make that kind of power and still be pretty efficient but not be so big that it's really laggy. Another good turbo is the IHI VF22 it spools up by 3500 rpm and holds all the way to your redline which makes a big difference when you race. So yeah the 16G can do it but it's getting to max it out making 300whp or 400 crank hp.

[@rextuner03]

@scoobiewrx And no I don't know EXACTLY what I am making but it is easy to guess when you know your mods and what people generally gain with their mods. Like I said some mods were done in preparation for future mods. Running the injectors and pump that I am running I would have problems with the classic lean out of cylinder 3. And at the time I did this video my car wasn't completely tuned when I shot this vid so I had problems with my cold idle. It is now up and running with having no problems.

[@rextuner03]

@Garac1991 I am running a GM Boost Solenoid off the GMC Typhoon. It's a 3 port and works GREAT. It holds up a lot better than the stock 2 port.

[@rextuner03]

@madscanman1 I am not sure, what year and model is your car? and being in the UK are you just messing up the conversion to mph from kph? But my downpipe is the same as everyone else makes a 3 and a half inch diameter which is standard for pretty much all downpipes. If you have the stock gear ratio and no mods to the internals to increase the redline. Then there is just no way that you could hit over 70mph without destroying your car.

[@Garac1991]

I have the same set up except im put an hta68 turbo, not sure what its pushing yet but i recently installed everything and will be getting it tuned very soon....are you running on the oem boost controlled solenoid? or aftermarket?

[@taconamedpaco]

Is your engine still completely stock? I want to know if you still are running the same setup and how has it kept up? Thanks ahead of time, Taco

[@rextuner03]

@theungrateful34 It's right in the neighborhood of 300whp. Which is the max recommended whp for the USDM WRX. You car has all forged internals so you can rock over 400whp on yours easy. Unless you are running more than 350whp you don't need to upgrade the STi topmount. By going to the FMIC you would get a lot more turbo lag. But hey to each is own.

[@rextuner03]

@tibu266 Lol that is for the rear O2 sensor it's being stubborn as fuck. I will probably just replace the whole sensor one of these days. I delete it with the Cobb AP BUT it keeps coming back.

[@rextuner03]

@tibu266 Does he have the 02-03 WRX or an STi? I only ask because a GT30R on stock internals is REALLY pushing it for the 2.0L the 2.5L can handle it alright but 2.0 not so much.

[@rextuner03]

@AnimepimpYT Yeah I need to look into doing that lol. They are pretty damn foggy,

[@rextuner03]

@bcruredneck i have spent around 10k now wth new motor, trans and stuff. And yeah it was a cold start up.

[@rextuner03]

@dunit9696 The one that I have I got off of Ebay the measurements are 20"x11.5"x4 1/2" they sell them on there all the time and they are pretty cheap. People will make you shy away from Ebay parts but I think buying intakes and stuff is fine just don't buy a turbo off of ebay lol. This intercooler is perfectly fine you will have some issuse with fitament so make sure to take your time and put it in as gently as possible so you don't bend any of your AC lines on the firewall.

[@elemento1991]

Did your wideband sensor ever go out? I heard that if you put them too close to the turbo outlet they like to burn up

[@BialyOrzel777]

whats ur normal idle rpm when normal tempature? because I see you have around 1200rpms when cold , I need a tune on my car because with piggyback on stage 2 and stage 4 that i have , car stalls on normal 750 rpms, i have UTEC as well but there is something wrong with it , the UTEC makes ticking noise or etc... i dont know made it needs to be grounded hmmm .....did u do a tune on a dyno?

[@rextuner03]

@tibu266 Yeah if you spray your intercooler it's after your turbo between the turbo and the intake so it would take a shit load to make a difference lol. I know plenty of guys that have done it and they haven't gotten very good results. But he to each is own.

[@rextuner03]

@tibu266 yeah it's easily possible to go too big on your turbo. I get full boost with my turbo around 4k rpm range and thats with the TD06 housing and the 8cm exhaust side. Slow to come to boost but when it does it pulls hard.

[@rextuner03]

@tibu266 Yeah the EJ20's can get to around 400-425 crank hp before they pop. Or that would be around 300-325 whp which I am right around 310whp and I LOVE it. I can beat quite a few cars on the road and nobody sees it coming lol. They are great motors but limited because the stock rods just aren't very strong. I have heard of a few people getting 350whp out of them but that is with FLAWLESS tuning and high octane gas.

[@rextuner03]

@sweetlikeADAM How do you figure that? And no nothing is or was leaking on the car.

[@Authenticselections]

what did you do with the other line on top of the fuel filter that goes to the stock rails?

[@AreyouMadbro123]

my wrx is a 2005 stage2 with xpt map. i'm trying to get more power on it, maybe around 300-320whp with a little up grade. do you think the 16g and the mod tmic can do it?

[@AreyouMadbro123]

1 question: can i pro-tune my wrx with the stock ecu cuz i don't wanna spent too much money for the cobb ap and how much is the pro-tune? thank you and your car looks sexy

[@scoobiewrx]

......and i forgot to add.......my car makes over 400bhp and i'm still using the stock airbox with a snuokus delete. That's it. You don;t have to go OTT to make solid reliable power all day long. Unfortunately most that know nothing fall for the bullshit some tuners like to give out in order to make money from those poor unsuspecting fools with more money than sense. Like most....you'll learn the hard way. Good luck!! :O))

[@rextuner03]

@scoobiewrx ALSO There is a difference on the US STi vs WRX bypass valve because the STi is running a bigger turbo and larger intercooler capacity and the stock wrx valve can't hold it end of story. If you are just modding out the stock turbo with intake exhaust and tune then yeah you are fine but once you upgrade your turbo you should upgrade the valve. Especially considering I am eventually going to build up to a GT35R turbo kit looking to hit 600whp+ along with head and cam work.

[@ty922]

what stopped you from doing a front mount?

[@TugaLife22]

where did you get that top mount intercooler from?

[@Slvr2k]

Hey I just picked up an 05 with 7 k on it very low mileage. I was thinking about the blouch 18 g as well does it pull nice hows the spool up. Thanks. PS I was also thinking about the pertinent fuel rails because of the crap fuel setup and lean cylinder 3 conditions any input appreciated

[@imbetterthanUbtch]

how much did this cost you? car+ everything you put into it= ?

[@AnimepimpYT]

Polish those headlights! lol

[@rextuner03]

@BialyOrzel777 At normal temp I am around 800rpm idle. I went and got an open source tune. I am not worried about dyno numbers so that's no big deal to me. The only thing that I worry about is how the car runs well and if I am 10whp shy of what I could be then so be it. UTEC is ok for just standard mods but honestly if I were you I would junk it and find a good reputable tuner and have them tune your car for you.

[@TheBeerBox80]

why is the check engine light on?

[@rextuner03]

@tibu266 Just an FYI a FMIC will hurt his performance unless he is going with a big turbo like a GT30 or GT35. I am running the TMIC as you can see and my friend has basically the exact same set up on his 03 WRX but he has a FMIC and I am faster than him because I don't have turbo lag. I get full boost at 3,500rpm and he gets it a 4,500rpm. Once we get going then we run the same of course but a large TMIC doesn't have any draw backs other than heat soak from sitting at lights.

[@rextuner03]

@thediscman6996 Yeah man I couldn't believe the quality of them for how cheap they were. My buddy bought some of the headers from greddy for like $1,000 and there was virtually no difference other than the header walls were a little thicker on the greddy vs my JDM but hell who really cares about that lol. I have to hand it to them those headers work great.

[@NYCMarineFish]

did the traNNY GO OUT ET? 5 speed stock?

[@rextuner03]

@tibu266 Yeah I have seen a lot of people do that and they never seem to get much of a hp boost by spraying CO2 or N20 on the intercooler.

[@NYCMarineFish]

@rextuner03 how much were the ppg gears?

[@rextuner03]

@madscanman1 No the highest I have taken it is 120 but I know where the gearing takes me. So that's where I was quoting that from. The other guy on here was saying he hit over 150mph in 4th which is NOT possible.

[@theungrateful34]

how much whp lol my 2004 subaru sti still pulling i did all actualy most supporting mods right now on stock tmic just wating for my fmic by aps stealth black and injectors and fuel pump its a jdm so iots 2.0l so im realy giving all also i am runnign ewg setup

[@rextuner03]

@bcruredneck Yeah I have spent so much because I built my whole drivetrain and everything. It costs so damn much to get the whole drivetrain beefed up. I sometimes cry when I think about handing over all that money lol.

[@rextuner03]

@imbetterthanUbtch $10,000 for the car and around $3,500 roughly for all the parts so far.

[@rextuner03]

@scoobiewrx Well walking the walk in your daily life is one thing but on here vids prove you aren't full of it. But also i totally agree, he told me he did over 150mph in 4th and claimed to be dead serious which I knew unless he had a higher rev limit then it wasn't possible. I can hit 130mph in 4th at 7,000 so there must be a little bit of a different in gear ratio. I know the final drive is 3.9 on ALL models but I know i hit 130mph at the top of 4th. With limiter at 132mph until i tuned it.

[@nowayjose20]

Fuel hose is leakin'...

[@rextuner03]

@tibu266 Luckily all that does is just throw a check engine light so no real problems. And the tumblers are fucking useless they shouldn't even be on there lol. I am going to be doing the tumbler delete pretty soon along with a fully built closed deck EJ25. I wanted to stick with the 2.0 and do forged internals but you just can't spin the bigger turbo's with the 2.0L. Biggest I could go on the 2.0 is maybe a GT30R but it would take forever to spool.

[@rextuner03]

@NYCMarineFish I got a deal on them, only 3 grand. :)

[@scoobiewrx]

rextuner03 wrote to me via email......... My reply................ IMHO Forge Bypass valves are rubbish. Every single one i have come across has given problems of one sort or another, not to mention sending AFR's rich in between gear changes. The stock air bypass valve will take a lot more that 18psi boost and should be good for well over 400bhp. They don't leak and it's a good bit of kit.

[@scoobiewrx]

The other chap is very likely winding you up as he probably well knows that you would have to be doing 8000rpm (156mph) for that to be true, and i know that car doesn't rev to 8000rpm because i mapped it!! At 7000rpm you'll be doing 137mph in 4th which is certainly achievable based on 3.9 final drive and 0.972 4th gear ratios. Hope this clears that up. As for vids....i don't have to prove a thing as i already walk the walk for a living, every single day!!

[@rextuner03]

@omgfroobynoobs Old for what?

[@rextuner03]

@scoobiewrx I do have a heat shield over my turbo I just took it off for the vid so you could see the turbo. Also you are thinking of the stock STi bypass valve as opposed to my 03 WRX which is not an STi. The WRX stock valves begin to leak with 18psi from the stock turbo much less a TD06 18G that flows around 600cfm it wouldn't hold up. So I think you should get your facts straight before you start being a Mr. Knowitall jack ass.

[@rextuner03]

@madscanman1 My redline is still the stock rpm and if you are running an 18g turbo at 22-23psi then there is no way in hell that the 565 injectors would NOT be enough to power that. I know you have internals done and if you have your cams and stuff done then there is no way in hell you would get enough fuel into your system, therefore you would run lean and melt your internals which you told me you did. I know these cars inside and out and your story doesn't match up.

[@rextuner03]

@getalife04 Yeah he is a douche I am not at all worried about him. I know what I am doing with tuning and working on cars, I have been working on WRX's for years so it's all good.

[@scoobiewrx]

Finally, you don't have a clue what power/torque your car makes until you've stuck it on a rolling road or have road dyno software on a laptop to give you a guestimate of what the car is making (WHP) so your figures until then are made up. It's clear you don't know Subaru's inside out, really haven't done your homework, and have carried out unneccessary work on your car for little gain. You're not a rextuner are you. How do i know this......i just do ;0)

[@rextuner03]

@brad13b Who are you talking to? If it's me I never claimed to have the fastest WRX in the world lol so if you are faster then good for you.

[@omgfroobynoobs]

Nice car but aren't you a lil old for this

[@jordanandmelissasalinas1438]

Aren't you a little gay to be posting on here fukin dumb

[@rextuner03]

@cobraman96 LMAO man you are like a turd that won't flush!

[@rextuner03]

@scoobiewrx Well that's cute you and your boyfriend are teaming up together. My typical AFR is 12.8-13.5 on full boost which is perfectly fine. I don't know what in the hell you are thinking of but there is nothing wrong with my car. I could give 2 shits about you being the top tuner in the UK thats fine with me I don't care one bit. It's funny you claim to have all of this done to a car yet you have NO videos to prove it? Hmmm yeah I call bullshit on you and your boyfriends cars.

[@rextuner03]

@scoobiewrx Ok have fun gargling your piss. If you know so much then what should my AFR be? What is the stoic level that it should be at during idle and full boost? What should my standard idle fuel pressure be vs under full boost. I would really like to know since you claim to know so much about these cars then let's hear it bitch. Bring on all this knowitall bullshit, so prove it.

[@rextuner03]

@scoobiewrx Wow you are so stupid you can't even insult people right. Me talking about polishing my headlights has NOTHING to do with performance you ignorant buck toothed little bitch. I was just talking about polishing then up for looks. And by bad business I meant that if you want to get business from people online then doing the dumb shit you are doing is a bad way to do it. You obviously don't know shit so fuck off little bitch.

[@rextuner03]

@madscanman1 I have no clue what in the hell you are talking about half the time because you regurgitate all this random shit about your car and how fast it is. And my car could smash a whole straight through yours more than likely. I just ran a 12.0 at 114 at the track. Yeah there is a chance you might be faster than that but not much.

[@rextuner03]

@twist6909 Did I say I have a lot? And I can smoke both of your cars :D And it's funny you call me a child, yet you are the one that went to all my videos to talk shit because I corrected your shitty grammar. So Mr. 4 Houses and 2 cars you are such a pinnacle of achievement. How can you live in 4 houses? lmao. Besides you don't have a clue what I have, I keep my personal life to myself on the web when you brag about it online it just makes you seem like a douche bag. So YOU'RE a douche bag.

[@scoobiewrx]

What's bad business is the shit you're doing to your poor car. I wouldn't say that was a bad tune, more fecking awful!! Now then....get back to polishing your turds...sorry i meant headlights, that'll make it go a bit quicker eh!! fpmsl

[@rextuner03]

@scoobiewrx ALSO There is a difference on the US STi vs WRX bypass valve because the STi is running a bigger turbo and larger intercooler capacity and the stock wrx valve can't hold it end of story. If you are just modding out the stock turbo with intake exhaust and tune then yeah you are fine but once you upgrade your turbo you should upgrade the valve. Especially considering I am eventually going to build up to a GT35R turbo kit looking to hit 600whp+ along with head and cam work.
