I'd compare this to swapping from a vf39 to a regular 16g. Yeah, you might gain a little on the top end, but was it really worth all the trouble for those extra 15 hp up top?

the question here is really matching the turbo's abilities with the cams, and because it won't give anything beyond 7k, I don't see much point in getting 272 cams, plus considering my main goal is response

Now those look tasty I think the "C" type cams would be perfect for a 20g. "B" for slightly better low end.

Alright, need some of the experts help here. I have a V7 swap going into a 04wrx and want to make sure I get the last wire right. My question is what is this "Shield Common Ground" wire that is plugged into the 14th pin on the B84 connector @ the ecu? What does it go to? This is the last wire I have to finish up the electric.

My source was DS1's write-up, (Kudos btw as it's really simple with this) I just don't know what to do at this pin and what its connected to.

Oh, and a little trick.......if you can get a donor wiring harness you'll never need to splice any wires and have the perfect length connected to the proper style pins. Its been a breeze! (Thanks Mccanixx!!!)



Just a little of whats in the bag:
Stock V7 long block (w/ functional AVCS)
FP Green 3" inlet
Bosch 1000cc injectors
Corn bo0ze! (e85)
FMIC
TGV Deletes

All straped to a PPG Dogbox

Quick qestion about ECU's. My current one is has an ecutek tune on it and I'd like to go to something that can be tuned by someone local rather than having to drive 500 miles each time it needs tuned. I have a line on another Ver 7 JDM STi ecu. I'm assuming that it's going to be more or less the same as my current AH970 ecu?

i'm pretty sure the ecu is the same. its the reflash version thats different. get yourself a tactrix cable and the romraider/ecuflash software and you can self tune. If your not that comfortable with a selftune you can send your image to one of the many vendors that e-tune. You log they tune....you flash....repeat the process until you the customer and they the tuner like the map and data logs.

Good to know. That was the whole reason to get a new ecu, to tune it myself, or get tuned by someone closer than 500 miles away.

V7 EJ207 owners:

I just picked up my Bug-eye STi and I'm not too far from installing some Defi's, Boost, EGT and Oil Pressure, I was curious what are the operating norms for this motor? The car had obviously been modified by the previous owner so I was hoping to get some insights as to what to look for as far as baseline numbers.

Any Version 8 guys do compression tests? If so, what were the results?

you probably wont find many answers, the number isnt that important but the variance between the cylinders is. Some say no more than 10% variance is acceptable, but the least variance the better. The numbers will read completely different a cold vs warm compression test.

My version 8 was compression tested at 112 PSI on all cylinders (cold on the garage floor), and leakdown tested at 10% for 1 & 3, and 12% for 2 & 4, also cold.

AEM told me they won't support any of the JDM AVCS engines when i called them.
I'm pretty sure it wont work anyway because the AEM EMS only supports the drive by wire 32-bit ecus.

most of the time you can purchase seperatley, or if your lucky, you get the jdm ecu with your motor and that is what will control your avcs.

Thought I would post what I just had built to put in my 01 RS, spent alot of time researching what engine to go with for the car. In my case I did not want so much torque to spin out of turns, also going with a 3" exhaust to keep the torque down even more. Also decided to stay with the 5 speed and install custom PPG ratio gears.

The ECU is a 2004 with a UTEK

Hope this helps. Remember that the 2.0 is a closed deck and has thick sleeves. While you will not have the torque of a 2.5, you will be able to pump alot of HP.


Some of the tech info on the engine.

1. Crower rods with metal free carbon coating
2. Wiseco forged pistons with coated skirts / Boring and honing with torque plate installed
3. Wiseco HD wrist pinsw / upgraded wrist pins and heavy duty rings
4. V7 Spec C crank
5. Coated ACL race bearings
6. Pinned block halves
7. Fully ported WRX heads and valve job with lash
8. DPR Stage 3 Cams (avcs holes are plugged)
9. Manley +1mm valves
10. Supertech valvesprings and titanium retainers
11. Balanced rotating assembly to 10,000 RPM
12. Torque hone plate bored and honed .5mm overbore
13. V7 Spec C block
14. Custom Steel Moroso oil pan- 6 quarts capacity
15. Modded - blueprinted 2008 STI oil pump
16. ARP Head Studs
17. Gates timing belt
18. Cometic Head Gaskets
19. New Tensioner for timing belt
20. Moroso high capacity 6qt oil pan
21. Moroso 3qt oil Accumulator
22. Mishimoto Oil Cooler

I do have the JDM ECU but I figured I would try to use the stand alone...guess not though. Anybody need an AEM Standalone?

It will run a V8 207 no problem, but it won't control AVCS. Check out an Autronic, Motec, Link, Vi-pec, or Pectel. They all make plug and play standalones that will control AVCS.

Anyone know anything about this pulley (on the left). I was told this is from a JDM 2002 EJ207 Spec C Limited (ie No A/C). I was also told this is made of titanium however after feeling it it seems a bit too heavy to be titanium.
