Got my protune done last night through Yimisport, 284/275 on a conservative "Stage 2" tune, no 6 speed yet.

So far I'm loving the V7, insanely smooth and very quick.

Only issue so far is the idle while warming up. The engine shakes violently like it wants to jump out of the engine bay. RPM seems to be ~ 900 and the temp gauge is just above the lowest mark, but goes away once it's fully warmed up

It's done this since I first installed it.

I cleaned the IACV when I first picked up the engine and put in a new gasket that should have expanded by now, going to snag another working IACV off my friends 205 that's sitting in my garage.


Anyone experience something similar?

Your stage 2 ver 7 makes more power than my ver7 with a blouch 18G XTR.
Check your coil packs, My car had 2 weak coil packs and shook as you describe.

You say that but you don't know what turbo he is running, or if he has headers, etc.. Maybe he has the VF30 and maybe not.

Did you install new coils?
Maybe your IACV is cracked, but if it was, it would act up more often that just at start-up.

Almost sounds as if the engine is being choked. Maybe the tune parameters need to be adjusted for cold start. Have you discussed this w/Yimisport?

Running the stock VF30, maybe it's just a high reading Dyno?

Nope the coilpacks are original, I may have to look into that.

It's done this since I dropped it in two weeks ago, on the JDM tune and now the protune.

I'll tinker around with it and see what I can come up with, aside from that it's running fantastically.

Thanks for the info

My car was e tuned recently, I actually have no idea what the dyno numbers are but on the previous tune the numbers were lower than the gentleman claims his car does.

Yes that was the first place I looked, initially had a set of Group N motor mounts installed but the shake was driving me up a wall.


Edit

Could this be a tell tale sign for clogged AVCS screens? I wanted to remove them while the motor was out of the car but my friend said they're easily accessible with the motor in - aka he didn't feel like doing them with me

Can't seem to find any useful information when googling Ej207 AVCS Screens, from looking at the photos it appears that the banjo bolts are behind the rear timing belt cover and impossible to remove without taking off the timing components.

You'll wish you removed them while the engine was out, can still be done but its an easier job when the motor is out.

IIRC, you should be able to directly access the driver's side AVCS banjo bolt. Removing the after-MAF hose should gain you access to the passenger side. I think it took me 5 mins to check both. And probably 10mins of wrassling with that after-MAF hose.

Just remember those coil packs are 15 years old. They are worth replacing.

Also remember: Numbers are a reference value for you, nothing more. You can't directly compare numbers. What matters most is what are YOUR numbers from YOUR tuner and how have YOUR mod changes have changed YOUR numbers with the same tuner/dyno.

anyone know if the coilpacks are the same as usdm motor. I got fresh ones for my ej205 before i did the swap. It would be nice to use those for the price i paid.

Default EJ207 Owners?

V7 coilpacks are black, just like 02-03 and I think 04 USDM wrx. I replaced all 4 on my v7.
V8 and V9 use gray coilpacks just like 05-07 USDM wrx and STi.

Can a brand new sti dealer clutch handle a V7 207 with bolt ons?

(This is for a 6speed)

Edit... I know it can* handle it... but will I get decent life out of it? I daily drive with the occasional heavy foot on the highway. No launching or drag racing.

Easily , The stock STi clutch will handle almost anything except repeated hard launches.

How much life anyone gets out of a clutch is directly dependent on the driver.
Drive like an ass and you will get much shorter life out to it.

" A heavy foot on the highway " has nothing to do with clutch life, unless you are dumping the clutch while you drive or riding the clutch.

Thanks for the quick replies, guys. That’s what I figured. Im not trying to race my car around the streets of nyc. Just wondering if it’ll hold the 300 tq at the wheels for more than 20k miles.

Thanks again ������������

unfortunately your V7 swap is probably no where near 300wtq , Probably closer to 260-270wtq at best.

It will be fine

Are the intake cam seals and AVCS seals on the EJ207 version 7 the same as the USDM variants?

What about the exhaust cam non-AVCS seals... are they the same as the WRX EJ205?

I've recently bought a 03 WRX fully converted to STi. Here's my setup:

2002 BUG STi EJ207 motor with AVCS (Can anyone tell me if its a v7,8 or 9?)
STi 6 speed DCCD tranny
STi drivetrain etc
Exedy stage4 clutch
APS SR40 turbo
Custom flowed pink STI injectors (840cc)
GT-spec exhaust manifold
Grimmespeed boost solenoïd
JDM STI ecu
Aluminium radiator
FMIC
HKS dumpvalve
Walbroo 255lph
3inch open exhaust
STI Intake
Brembo's all around

It's currently mapped at 385HP/460NM TQ. Does anyone have an idea what kind of power I can squeeze out of this car? The previous owner said I could crank it over 400hp, but didnt mention any exact numbers.

Sorry if it's offtopic, can't create my own topic yet as i've got 0 posts

Also, when the car is cold and I try to start it I have to pump the gas pedal for it once or twice in order to start. It's like the car is not getting any fuel untill you do so. No problems after that, runs smooth as butter.. Anyone knows whatsup with that?

Sounds like a V7 engine if its got a single scroll turbo bolted onto it , That sounds healthy.
