This turbo was much more responsive, with little to no power loss. Now I'm running another Kinugawa, a G30-660 hybrid. Don't have any videos of it yet, but it's just as responsive as this 18K. And makes more power.

I have a catless up-pipe and downpipe. But I had my car tuned before Cobb implemented their "Greenspeed" policy, which prevents tuners from tuning around emissions device removal with Cobb's software. However, the up-pipe cat isn't a very crucial part of the emissions system, and Subaru only used them for a couple of years. Removing it shouldn't cause any issues with a Cobb tune if you have downpipe cats.

@@madwagon9775 I'm trying to improve the shifting still. What do you have your rev limiter set to? Does Cobb allow you to adjust shift points for the auto? Thanks so much!

@@pendaranroberts4350 It's still at the stock limiter, 6500. And no, it doesn't. The best you can do is play around with the requested torque tables, to trick the TCU into thinking it needs to shift later or sooner. As far as I know, the only people who've actually tuned the TCU directly have done it by replacing the stock one with a different one that can accept a custom tune. But idk how to do that, and the few people who've done it haven't posted how to do it online. At least not in English forums, lol.

@@madwagon9775 Thanks. That's kind of what I've been hearing. We put the TCU into relearn. That improved things at first. We're still trying to get the car not to hit the limiter under WOT in auto mode. Manual mode usually works if you time it right. The actual shifts are good. Does the auto mode hit the limiter for you? If not, did you ever have this problem? How did you fix it?

Hm, that's weird. Mine's never smacked the limiter in auto or sport. Only in manual, when I'm not paying attention and forget to shift it, lol. Idk where to tell you to start with that one, sorry man.

V1 EJ255

It's a Vibrant 12810 core, and I made the piping myself.

Oops, yeah I took it down bc I'm running a different setup now. That tune was with a 20G, but before that I had a stock VF52. They both hit peak boost in the low/mid-3000s. Stock engine, and I did all the work myself.

@@madwagon9775 what bov are you were/are you running?

@@saki10man I'm not, lol. Never put one on after I took off the stock intercooler.

@@madwagon9775 that’s great. You must have one heck of a tuner!

@@saki10man I've been to Elijah Nichols in NC a couple times (his dyno in the video), and Alberto Correa in New Orleans did my most recent tune. They're both great.

I don't have any videos of them, but they're just as fast as the upshifts.

Custom, and yes. It had a lot more done than just the intake at this point.

This was with a Kinugawa TD06-20G, but I got it used and did rebuild it before I put it on. Thanks! It was a good turbo.

⁠@@madwagon9775 sounds great. Love how your exhaust sounded. Was the motor built too? Looking to rebuild a VF52 now, who did your turbo rebuild?

@@saki10man Thanks! Nope, factory motor. Still kicking with a bigger turbo now and 200k on it. I rebuilt the 20G.

@@madwagon9775 that’s great for a motor with that many miles. 😄

@@saki10man They'll last a while if you treat them right!

Factory unopened engine. For the 20G and up, I've been running a 3"-2.5" intake, FMIC, bigger injectors and fuel pump, equal-length headers, 3" catless turbo-back, and a few random supporting mods like an oil cooler. I'm running a Kinugawa ball-bearing TF06/ G25-660 hybrid right now. Spools like the 20G, but makes power like the FP Green. I'd recommend one of those or a GTX3071 hybrid.

Every dyno's different, as is every car. Dyno numbers aren't a very reliable way to compare different cars tuned on different dynos.

What injectors/fuel pump you running?

I made it a few years ago. Search up "DIY Mesh Grille". They're pretty easy to make. The one you got is probably for an LGT. They have shorter grilles.

No bypass/ diverter valve on the intercooler piping. Search up "turbo flutter" or "turbo dosing".

Турбина быстро сломается от таких действий

@@evgensha I haven't had one for years. Not enough boost going through an average Subaru for it to hurt anything.

Thanks man. No BOV, just turbo flutter. And yep, front mount. I've got about $250 in mods for mine, between a TransGo shift kit and a secondary cooler. It's definitely the most cost effective option if you aren't aiming for more than say around 450whp. After that, the center diff starts becoming a liability.

@@madwagon9775 ahh yep, probably a lot less expensive for you to do auto trans stuff as all the producers for the parts are in the states, be a bit more expensive to ship to New Zealand haha. Love the car!

You can try doing a TCM relearn if you haven't already, and it may help. If not, I would drop the valvebody out and check/ clean the solenoids on it.

@@madwagon9775 How many RPM's does yours take to shift from 1st to 2nd after hitting the button under full throttle and from 2nd to 3rd?

@@pendaranroberts4350 I've never measured it, but there is a noticeable delay. It doesn't smack the limiter in normal or sport modes though. No way to completely get rid of the manual input delay, because of how the tiptronic system works. But I feel like it should be closer to 500-1000rpm rather than 1500.

@@madwagon9775 It shifts from 2nd to 3rd in about 400rpm. It's just first gear that's slow. I have always felt first gear was the worst to shift. I'll try taking it to a trans shop and have them take a look at the valve body. Thanks so much for the communication. It's very helpful.

thank you

The post didn't assume horsepower or times😂!

Hey, it was $15 and it's been working great for years, lol.

Not bad. Messy, but not overly difficult. Between the included instructions and Hexmods' forum write-up on installing it, all the steps are covered in detail.

There could be one of a few issues here. A healthy stock 5EAT can handle a VF52 just fine, so while a shift kit and trans cooler may help the issue, I don't think that'll be a true fix. Though they're definitely great mods to have for the longevity of the trans. Have you already had it tuned, or do you just have it installed waiting on a tune?

It’s been tuned. The 5EAT was performing fine before the upgrade. But it can’t shift correctly now. It’ll shift fine if I’m driving normally. But if my foot is in it it just keeps reving and doesn’t shift. Even if I put it in manual and tell it to shift at 4k it wont till 6k even under half throttle.

@@pendaranroberts4350 Hm, that sounds like a communication error between the ECU and the TCU. I've seen a similar issue before on a buddy's car. The problem was an issue with the requested torque tables in his ECU, which is something the TCU references to make its shift decisions, along with engine speed and calculated load. If the values in these tables aren't scaled properly or have missing information, then the TCU doesn't have the information it needs to shift the transmission correctly. Ask your tuner to review these parts of the ECU map before you install any trans mods.

@@madwagon9775 I did some testing on the way home. When driving normally around town the trans acts fine. At half throttle it revs to redline. Under full throttle in first gear it'll hit the limiter. It doesn't seem to be slipping though. It's just not shifting when it should.

@@madwagon9775 Thanks so much for the information. I appreciate your expertise. I'll ask about torque tables.

Not as much as I would like it to, lol. I've gotten it closer now, with increased ignition retard during shifting. The ECU doesn't support full ignition cut like DCT/ DSG cars have though, unfortunately.

I'm running an Accessport, so through Accesstuner. Now that the Green Speed update has hit, I'll have to switch to opensource when I want to get tuned again.

@MadWagon97 I need a base map, could you send the tune somehow?

@@JLeeGBABY I don't think I can legally do that without consent from my tuner. Afaik, tunes are considered intellectual property of the tuner. I can give you his contact info, if you'd like.

Please do

@@JLeeGBABY Sure thing. I had my car tuned on the 20G by Elijah at Redemption Racing in North Carolina: [email protected] My current tune with an FP Green was done by Alberto at Corr Performance in Louisiana: [email protected]

Yes, this tune was with a Kinugawa TD06SL2-20G at about 21-22psi. 8cm turbine housing and a billet 11-blade compressor wheel.

@@madwagon9775 I figured. I have similar set up lol 25psi on meth also auto

@@juancarlosdelrio486 Nice! I'm running an FP Green now. Less boost, 20-21psi, but it gives much better power delivery up top.

Any new videos? I'm still kinugawa td06h 20g 4eat but loving the set up

@@juancarlosdelrio486 Got a few videos of my FP Green up, but I haven't had time to make any more, recently.

No, the flutter comes from not having a BPV or BOV at all. Yours will make a muffled pssshh sound.

@@madwagon9775 gotcha. Sounds badass

@@ThePrivateryan1323 Thanks man!

It's a Wika industrial vacuum/ pressure gauge I got from McMaster-Carr. Not meant to be on a car at all, lol. But it's worked great for years.

@@madwagon9775 thanks for the response. Reminds me of an old school racecar I saw in best motoring that used an industrial gauge as a boost gauge. 👌

Yep, that's what a shift kit does for you. It allows the valvebody to send almost full pump pressure to the clutch packs, which gives you faster, firmer shifts and stronger clutch engagement. I would recommend you run an auxiliary trans cooler if nothing else. I've been running a Hayden 676 auxiliary trans cooler, TransGo shift kit, and some ECU tuning for the trans from 300whp with the VF52, to 330whp and 360whp with a 20G, to now 400whp with an FP Green, and the trans is still doing just fine.

@@madwagon9775 That's awesome. I have a 5EAT 2005 Legacy GT. I love the car. Was thinking of getting a new WRX, but just don't see the improvements being worth the price. Currently got an up and down pipe, sway bars, and a pro tune. The 5EAT is the thing that bothers me most. Love it in traffic. I'm a lazy guy. But it shifts too slow. You say you have ECU tuning for the trans? Could you say a bit more about that? I'm looking to eventually put in a VF52 for 300whp but my tuner was worried about the 5EAT.

@@pendaranroberts4350 There's a parameter in the ECU called "AT Shift Timing Retard", which retards ignition timing during shifts to cut some power to help prevent slipping. The factory values bring the overall timing to about 5 degrees BTDC at WOT. Mine is set to 22 degrees after TDC, so it's basically making no power during the shifts. Between that, the shift kit, and the additional fluid cooler, I've never had any issues with slipping. Even with almost 200k on my trans now. The weakest part of the 5EAT after beefing up the shifts is the center differential. It's sensitive to shock loading, like during a hard boosted launch. So long as you aren't launching it hard, it's good for around 450whp reliably, and can handle upwards of 500 for a while.

@@madwagon9775 Thanks so much for the information. Gonna talk to my shop about the shift kit, a trans cooler, and a trans ECU tune. Once I get the trans working good, I'll look into the turbo upgrade later on.

Do you have a high stall converter?

Thanks! To my knowledge, there aren't any valvebody mods available for the revised 08+ 5EAT anymore, unfortunately. Though I would still recommend adding an auxiliary ATF cooler. I'm running a Hayden 676 on mine without a thermostat, plumbed in line after the stock in-radiator cooler. I'd also recommend running a synthetic ATF over the OE-spec Idemitsu HP fluid. I run Valvoline Maxlife with a bottle of Lubegard Red, and it works really well.

@@madwagon9775 Thanks for the reply. I have a Mishimoto external cooler. I never thought of using anything other than the HP fluid. I will definitely take that into consideration!

@madwagon97 how can i send you a message or a email i will be buying a trans go kit for my 05 lgt and had a couple easy questions. I follow all your videos.

@@mikev350z Sure thing, man. You can ask them here for others to read, or shoot me an e-mail at zachcouch1997 @ gmail.com

Well I got my car tuned. Laid down 287HP/397TQ. Think I need to upgrade the torque converter and tranny. I love how she pulls when I overtake cars now. In the future I would like to pull the engine back out and stiffen up the internals and slap a bigger turbo on her. I think 400whp is the max of where I would want to be. People always say they want xxxHP yet have no idea what it means until they drive it.

Not very difficult, just really messy. The kit comes with good instructions with pictures and diagrams, and it's pretty easy to follow. Just have a couple of large drip pans to work over and plenty of rags, otherwise you'll have trans fluid everywhere.

@@madwagon9775 thanks for the reply I really appreciate it.

@@madwagon9775 were there any changes to software needed?

@@S54 You may want to reset the TCU with an SSM tool so it can relearn, but it's not strictly necessary.

It's been a good one! Has some quirks, but it's still handling power just fine. I'll rebuild it if it ever blows or starts slipping.

93 for all of them.

Yep, 5EAT with a few mods. The Green is noticeably less responsive than the TD06SL2-20G I had, but it's still easy to daily with. And it makes a lot more top end. I ease in to the throttle when I'm doing a pull, so it looks laggier than it is.

@@madwagon9775 that's good to know. I'm running a tdo6h 20g and 4eat with ratiotek shift kit. Was looking into getting a green but the stock stall is already kinda low. You using stock computer? I seemed to of maxed out the stock maf with the 20g at 25psi

@@juancarlosdelrio486 The Green uses the TD06H turbine as well, just with a 55x76mm comp instead of the 53x68mm 20G comp. You probably wouldn't notice as much of a response difference coming from another TD06H turbo as I did coming from a TD06SL2 turbo. I'm still using the stock ECU and MAF. I maxed out the MAF with my 20G and a 2.75" MAF housing, but moving up to a 3" gave it some more room. It's still working well with the Green so far, but I'll probably have to switch over to a MAP setup if I want any more.

Thanks!
