My recollection was wrong, I was reading 100 lb heavier in older threads.
Was never specified dry or not.
It makes up a part of the weight difference between the WRX and the Sti.

The overall drivetrain makes up the weight difference, R180 and Brembos are significantly heavier.

Anyone know if the v7 Sti radiator is more efficient at cooling than the Wrx radiator? I had a v7 laying in my garage and decided to put it in for the hell of it.

in my experience, the stock radiators cool well, but they blow out the plastic endtanks. so if the v7 has plastic endtanks, it'll be the same.

Just bought a car with an ej207 engine. Its an 03' JDM Ver8 STi converted to LHD, came stock plus cusco 2 way rear diff (clunks like a b*tch).
Already got a perrin turbo inlet hose, whiteline steering rack bushings and a full TBE. By the end of the month I'll install them and take it to the dyno for a reflash.Also the car is electronically limited to 180 km/h, i guess the reflash will take care of that.

Hope that's not true because that's what I use in mine! I have an atpgt3076 setup.

Unless you know the model number of the plugs you plan to use, you won't know what they're colder than by one step.
Once you know the model number of what you're planning to use, go back in this tread, read and you'll find the answer.

Hey everyone,

I've been looking to do a v7 swap and found a spec c clip however it has over 85 thousand miles on it (converted from km). Does that seem a little high, would it be worth getting?

I am running NGK BKR7EIX plugs in my V8 swap with great success. It is tuned for California 91 octane pump gas and put down 280 horse and 276 ft-lbs of torque at 19lbs of boost. The only things I have done to the engine is a 3" Catless TBE, K&N typhoon intake, and a new MAF sensor.

My car is registered in a different state that doesn't require emissions testing. I have not had any problems so far.

I was wondering if anyone here knows of a good tuner in washington state that has knowledge and experience with JDM EJ207's? I am moving there and I am hoping to get tuned for 92 octane instead of the Cali 91.

Thanks for the help.

.... Hello?
Yes, this is dog.

I have read quite a bit through this thread, but I didn't find any info on where to get replacement engine internals. I'm buying a V8 EJ207 complete engine soon, but it needs rebuilt. I don't know too much about what's compatible. What's a good site I can get rebuild components for the block? I'm almost 100% sure the heads are fine. So I just wanted to get the block rebuilt and running strong for the long-run. Thanks!

Oh, and would I be able to get an e-tune for it? Say, from Clark Tuner? I don't own an AP. My tune on my car right now is an opensource map from XPT Tuning. Closest tuner to me is P&L Motorsports in the Chicago area and it's still quite a drive.

I can't comment on the replacement internals, but STIMikey does etunes and tuned my EJ207 for pump an E85 along with many others.

I just finished everything on my V7 EJ207 swap in an '02 WRX. I used the IAG AVCS wiring harness and a V7 ECU. I went to fire it up for the first time and it cranks but doesn't start. I don't hear the fuel pump priming in the on position. Did I get a bum ECU?

I just got my Ver. 8 swap completed by MPS in Marysville. Call them up. I'm getting retuned for some additional mods december 19th. Dom put the group N rom on the ecu so I have launch control via the rear defrost button

Dave and Dom are both very familiar with my car and a couple other EJ207 swaps they've done. I'd just give them a call and see what they say.

Ok, I was getting no CEL with the key in the "on" position and the fuel pump wasn't priming. I swapped the US ECU back in and the pump primed, it started, but died without giving it a little gas.

So 2 questions:

1. What's the best source for a V7 ECU? Looks like I got a bad one.

2. Is it normal that the US '02 WRX ECU won't allow the V7 STI motor to even idle?

Cool. So I am guessing I have a vacuum leak. The ECU my V7 shipped with turned out to be a V9.

V7 ECU is on it's way and I need to fix the vacuum leak.

I too would recommend Maxwell Power in Marysville, WA north of Seattle up I-5. They have the experience, plus you can get a Dom tune!
