Thinking of swapping the sti jdm vers.10 ej207 into my 2014 sti, timing tensioner failed and uncle Rodney came knocking. I chose the vers.10 as its directly from the same chassis as mine, better internals than the 257, elh, twinscroll, higher revs etc etc. Both 32bit ecus, what I've dug up from Nasoic is its not too terrible to get the engine cooperating with the car harness wise. But if I was going to through all that I figured it would be best just to go for a standalone ecu as tuning the jdm ecu sounds very tiresome and limited and converting the engine to the usdm ecu sounds like a harness nightmare. Standalone would give me a lot more future tunability down the road, rolling antilag, launch control, tune the sensors to read the jdm so as to not have to go through the conversion process. As for the turbo.... **Could I just cut the flange off my existing downpipe to turbo section and weld the proper fitting one for the vf47?** I have the Cobb turboback, I would prefer to reuse it as I quite like the deep resonance from it. And I do prefer a twinscroll over a single scroll, I don't plan on doing anything crazy turbo wise, I figured I could just have a turbo shop bore out the compressor housing to fit a larger compressor if I wanted more oomf out of the vf47 in the future.

Dude, show us the brakes 😂

Gotta love subaru nuts. What a legend. Hoping for some good runs and clear skies for you.

Good luck boys. Will be looking forward to seeing you guys make it up..cheers!

“it’s a marathon not a sprint”…actually it is a marathon *followed* by a sprint! 😜

Curious if you still have the factory AC and heater core in place? Also, you didn't say in the video. Are you running the stock radiator? If not, what aftermarket radiator are you running that failed? As this car evolves I think you're going to have to go with some wide aero kit and mount the radiator in the rear trunk for better weight distribution and finally resolve the cooling issues. Glad you were able to get the donor long block and swapped out and Godspeed on Sunday 🌪️💯💯 🏁

Hi Good Luck Sunday .Could you possibly do Pull down .Examination and Rebuild of the Failed engine Video ?

Man, Jeremy is a BEAST. Hope y'all rewarded him with a pit pass or something.

Great video! Question unrelated to your video but performance related, have a 2022 VB WRX and everyone talked about how great the FA24 was so got it. But one thing never talked about was the poor handling, already spent $5k on coilovers, bushings, sway bars, Advan wheels and 200tw tires, but mid-corner and corner exit is horrendous still, got to wait until whole corner is done and almost straighten until lay power down. Drove a completely stock STI and it's insane how different it was, mid-corner can already put the power down without it wanting to push. At Streets of Willow Springs track, the modified VB did 1:28 and the completely stock STI did 1:25. I reached out to a big Subaru tuner locally here in California called Renner and they said what I described was due to drivetrain, that the new VB WRX uses open front and open rear diff and that the STI has front LSD, center DCCD diff, and rear LSD. He said that front LSD cannot be added at all to the front of the new VB because of the transmission, and that were I to add it I'd have to spend $10k in parts and labor for STI front, center, and rear drivetrain. The car itself was inexpensive at $30k, I've already spent $5k in suspension mods. My question to you is do I really need to spend another $10k to get STI drivetrain? If so, would it make more sense to just sell the VB and buy a STI to begin with?

Best wishes from Australia.

I'm pulling for you guys!! &%$#@ send it!! (with love from Littleton!) 🥰

Bad ass!!!

When the rod come out the hood right??? Haha jk usually when my motor sees knock it’s all over. It doesn’t take very many det cycles to happen before 🎉

Nice update. Typical Subaru. Motor pulled lol. Looks like mine, I had a bearing by 5th gear transfer shaft fail and seize

Does the IAG aos affect the return of coolant to the turbo when engine is turned off?

Garret gt28 is probably the best matched turbo for the 2.0 and the 2.5. I have the Gtx3076r with tial v band 82ar exhaust housing. Very very very happy with my setup. My crower cams really changed the top end as well. The car pulls to redline it doesn't hit boost then fall off after 5k anymore.

I'm visiting family in Denver currently. I have two GC coupes back home - one getting a 257 and 6 speed soon, and a fairly stock 2.5RS. Any recommendations for parts I should get from you guys that are only available for pickup?

The guy in the middle victor, I copied his set up with a 12 mm pump and proper clearance rods and mains and have have had nothing but awesome results. That video changed my life way back when haha

So pumped. I’m ready to hear that subie roar up the mountain.

How can I find the CAN bus H and L cables to connect to my aftermarket power tailgate in my 2019 Subaru Crosstrek?

Couple of handsome gents

So sequential it is❤

None of us are surprised how expensive this is 😂😂😂

I love my 5 speed but we built a 400+ hp setup and I'm only on 10psi 😢 Its been my daily for about 3 years and no issues but in turning the power up finally and I know the trans isn't going to last.

I’ve been running a uniclutch sport on my 2017 WRX for maybe 3 or 4 months now. Happy to share my my experience as well if you’re curious

Well done. Thanks. I agree, HKS design = max flow.

Every one is fighting for that colder dense air in the morning haha

This close to the race man. Time to send it

Bring back flex for 04+ STI’s. I’ll buy it. Kudos for getting Cobb on the channel Jon.

The expansion tank vents to the coolant reservoir via a tube that is kept in coolant at all times. This allows the system to heat up and cool down, while pushing coolant in and out of the expansion tank without sucking air back in (which could lose your bleed of the system). Since the radiator vents to the top of the expansion tank, you want it to be able to push coolant out, but not pull anything back, because it could pull air back in and lose the bleed. The recommended way to set this system up basically allows for the proper regulation of pressure and control of thermal expansion in the system while having an ambient-pressure coolant reservoir available to the user and not allowing any air to enter the system. That being said, if you REALLY fill the expansion tank up, you probably won't ever get enough air in the cooling system to cause a problem, but if you 1. don't get the tank completely full, or 2. allow air to enter the expansion tank in some way (e.g. low coolant in the reservoir), you could end up in trouble.

I got my 2016 wrx In 2017 with 18k miles. The coolant appears green?

Awesome update guys. If your leaking water out the intercooler sprayer a one way check valve with pressure relief valve will stop the drip. I gotta know what hood is that?

My 305bhp hawkeye twinscroll has a fairly linear torque curve from 2k rpm all the way to redline. Much prefer it to the kick in arse single scroll that runs out of puff at 6.5k.

Ob1, I missed this vid. I'm glad I found it, do you believe WPC is effective in a part like this? Would you recommend porting where the oil is feed to the oil filter on the block?

Does it fit the 2016 wrx?? Been looking so long for a good replacement kit

LOOKING FORWARD TO SOME FA24DIT/F FLEX KITS. ETHANOL THRASHES MOTORS IN THE LONG RUN ( FUEL DILUTION, OIL ADDITIVE PACKAGE BREAKDOWN/OXIDATION, CONDENSATION ETC) BUT IT DEFINITELY HAS ITS PLACE AROUND E40-E60 AND THE COOLER/DENSER EFFECTS', AND IS GREAT FOR TUNING SAFETY ( ESPECIALLY KNOCK PRONE FA20'S) AND WEEKEND WARRIOR TRACK STUFF. I NO LONGER DAILY MY CARS ON ETHANOL BC OF OVERALL LONG TERM RELIABILITY ETC BUT I DO USE THE FLEX KIT ON MY EJ'S WHEN I WANT TO GO OUT TO A TRACK DAY. LOOKING FORWARD TO FLEX KITS FOR THE 22,23,24 VB WRX SPECIFICALLY THE 23 FOR NOW LOL

Thanks for the info, 52k on my FA-20 and have been burning 0 oil since i bought it (first owner). Feel a bit better now about not putting one on, but am buying one now since im preemptively replacing the PCV with a new valve and will already be there. Choosing catch can because i change my own oil and it will just be apart of my regimen. Appreciate your content!

What's the exhaust setup? Sounds killer!

We race up to the clouds not because it is easy but, because it is hard.

That Ford f150 sounded like a tank rollin down the street. Awesome lol

Go Flatiron boyz!! thanks for the update Jon,always facing challenges on the Mountain

Awesome video!!! I am learning lots. A related question of ethanol fuel system and the COBB hardware and software; can your gear and software be set up to regulate when an ethanol+water injection system is set to off, on, and then turns off again? I have heard from a few sources that driving very short distances, say between 0 to 10 minutes, with either E30-85 or ethanol+water active from a cold start can cause a black gel like sludge of deposits to build up in the engine and cause major problems. So to clarify, can the COBB hardware and software be set up to engage the use of ethanol+water (in the intake manifold or charge cooler) after a few minutes of initial driving after cold start, when the engine has had a chance to warm up, and then alternatively be manually selected to turn off whenever the driver wants to? Can an existing engine temperature sensor on the car (or added sensor) be used to trigger the start of ethanol+water use when the ECU knows that the temperature is in the correct window for optimal use?

Lance tuned my Sti many moons ago. He wasn't perfect but that tune allowed me to beat on that car with elevated power levels for years without worry. When i finally pulled the engine at 90k the engine itself was still in great shape. Just started getting oil leaks. I am very grateful. He certainly knows what he is doing and we should absolutely listen to him.

My 2005 LGT disliked that.

What I dont understand, is why they don't market the old flex fuel kits as for "Off road use ONLY". Then push out reminders to the customers that the mod is not EPA street legal, so it should be used at their own risk. I dont know how much legal pressure Cobb was dealing with from the EPA, but the government should not have the right to tell a aftermarket perfomance car part company what they can and cannot sell.

We will never forget what you did to your customer base when yall folded to the EPA. Never will I buy another Cobb product

Personally I understood the pulling off of the band aid, but the way they went about it was like spraying it with alcohol.

Do they say if CARB approval is coming soon?

GD drivers lookin' like 👀👀👀

One fits all. No thanks. That adapter for input shaft is probably first thing to break. Time will tell.
