I thought 250 might be low, but I haven't put it on a real dyno to know what it really makes, it pulls hard though.

Good to know that the 5 speed can hold some power at least on the road.

v7 = 02-03
v8 = 04-05
v9 = 06-07

I'm doing my v9 swap into my 03 WRX next weekend. I'll be sure to post up my experiences as well, and follow this thread. Brilliant write up man!

The 5 speed will take a bunch of punishment. Your stock clutch will too. At 350awtq the clutch will go usually pretty quick. As long as you don't clutch dump and or launch the car, the trans will last. It only has around 15 "shock loads" before it's beyond it's engineering. The fancy BMW sequential box will lock you out of launch control after so many launches. The gear sets are not ment to be launched on like that. The 6 speed will survive 600 tq about before you break stuff. If you plan to drag race you need to mod you trans or go to a six speed.

I did a full V7 swap into my 2002 bugeye wagon. Loving it so far. I did the v7 6mt w brembos hubs axles etc first this winter and just did the motor swap about a month or so ago now. About 4k miles into my swap now and I love it. I had a perfectly fine running 205 w 189k on it and a 5mt that was Mint I pulled working and sold w 178k on that. The 5 speed should last a while as said if you change the fluids etc. I'm running an 18gxt with every other mod except EL headers and my old setup was running perfect when pulled. I could have even kept the 5mt w the V7 but eventually I want to break over 350 and get closer to 400 for my DD. fun setup right now though and getting a dyno run soon finally. Should be close to 350 w the 18gxt @ 22psi. How are you liking your swap? Best decision I made yet with my car almost went built 2.1 so glad I didn't!

My v9 arrived yesterday. It's going in tomorrow. This thread has been a wealth of information. I'll be sure to add my experiences as well in case anyone needs troubleshooting help.

^nice! did you get a v8 or non immobilized v9 ecu? I will be attempting this swap in the next 2 months or so.

v8 ECU. Didn't want to take the risk of the v9 being immobilized.

Engine is IN!!!



Was pretty straight forward. And a super easy install.

1) Change Timing Belt
2) Move over flywheel (make sure to do timing belt first so you can use the flywheel to hold the main shaft to take off/on the main cam shaft bolt).
3) Re-install clutch to flywheel, and throw-out fork/bearing to trans.
4) Drop engine in. (We had to unbolt the turbo from the up-pipe to get it to fit past the bell housing on the trans, but it was easy enough.) It was a little tricky getting the trans jacked up to the right height to get everything to line up right, but just work slow, and you should be fine.
5) Install Downpipe.
6) Swap over O2 sensor. The JDM O2 sensor is on the downpipe instead of the headers, so it’s cable is the wrong length for the USDM plug. Just swap over the USDM one and you should have plenty of plug length.
7) Hook up all the hoses (we left them on the car, so it was pretty simple).
8) Prime engine and Power Steering.
9) Connect everything.
10) DONE!

I still have 3 hoses that need replacing (old and cracked) so I should be 100% done and able to give a full write up (or just expand this one) later. More pictures to come as well.

Cheers!

TX, the state computer kept dropping but would not even run a single test against the system. Inspector was puzzled even his hand held obd2 scanner showed everything looked good but officially could not run me through the rest of the inspection.

NJ last year, state computer showed all my tests were fine but a few criteria they were looking for did not report back, so they failed me. Tried again with the force readiness bit on, still failed. Had to use a usdm ecu to pass.
Md, mine passed but the machine couldn't get a reading of the rpm . the manager had to check it out because it was showing communication with the rest of the ecu

Are there any additional grounds on the V7 ej207 that the 205 doesn't have. I have a ground on the alternator and block that the 205 didn't have. Motor runs great on wrx ecu. JDM ecu is really choppy and bad idle but no CEL. Do I just need to get it tuned? help please

It's not the same but can run your engine, you just need a tune.

@redline

vf37 is the Turbo, not the ECU.

If you are not using the JDM ECU you do not have AVCS (even if it's wired). The USDM ECU does not know how to run AVCS.

Your JDM ECU is choppy because it is tuned for 93 gas. You have 91 in there, so it runs funny. You NEED to get a tune (even if you are running the USDM ECU) if you want your engine to have a long healthy life. You can go the route of an opensource tune (there are some maps on rom raider) but i would recommend a full pro tune.

These are all things you should have known/budgeted for before doing the swap. Make sure to do these, or you run a seriously high risk of have trouble with your new baby down the line.

Did anybody ever reply to this? I'm about to do the install and am wondering exactly what this does. Does it just basically dissipate throughout the conduate?

It's actually really easy to pass smog. You just need your USDM ECU with the readiness codes forced. It wouldn't throw any CEL without forced readiness but since CA smog looks for the individual readiness codes, and the JDM ECU doesn't have a 2nd O2 sensor, it's not there to be ready, and thus fails.

Other than that there is nothing wrong, stock JDM DP will pass sniffer, and everything else is perfectly smog legal.

Passing smog in CA:
1. Connect USDM ECU, forced to readiness (or drive it 30 miles off boost).
2. Get smogged.
3. Swap back to JDM ECU to get your AVCS back.

Obviously if you are running aftermarket parts YMMV, but that is true with any USDM motor as well. A 100% stock EJ207 will only have an ECU problem, otherwise it's all good.

Use the JDM ecu. You are missing out on a huge difference with the AVCS. As stated earlier, the USDM wont run the AVCS. Get it tuned and be a lot better off. I just went through a lot of troubleshooting to get it to work. Now that it does, I'm VERY happy I took the time.

So got everything running on the 207 last night. Turned over no problem. Ordered my AVCS hit today, and will have her tuned as soon as AVCS arrives, and it's wired up.

For anyone else who wants to just use the pre-made AVCS kit, look here for a plug and play kit. Guys at IA were AMAZING, and got me all set-up and shipped ASAP:

http://www.iaperformance.com/product...6qh5qhja3qogj2

Engine currently idles high (2k) but that should be because AVCS is missing and thus the ECU doesn't know cam positions. Once AVCS is wired it should quiet down. Also tuning the JDM ECU should help with any 91 vs 93 octane issues (potentially also causing the high idle).

My bigger problem is now my car is loud as F***! Have a Blitz NurSpec Catback on there, and will have to swap back to stock until I can find something quieter. It is 40-70% louder than the USDM EJ on the same catback.
