Default swaping version 8

i wanted some feedback on my almost made decision....im planing on swaping a version 8 into my 2002 wrx. In all the swap should cost me around 7-8000$. The swap includes the engine,transmission,diff,axels,wiring and down pipe. Is it worth doing this to my 2002 for the money its gunna cost me?

In my opinion no, i wouldn't put a v8 in it, unless you are in LOVE with the bugeye look. Also are you doing all the labor?

You'd be better off selling your WRX and stepping into a 04+ STI, you'd be much better off.


If you really wanna get fancy, find a V7 (JDM), that would make your car godly.

Yes and no, but mostly yes.



The v7 came with fully forged internals, making it a very very good block and able to handle just a boat load of power. They are still expensive because of this fact, and sometimes hard to find.

I say roll a V7 because that is the STI engine that came on your car in japan. I"m not a fanboy in any sense of the word, but a Bugeye with a V7 is my idea of a very very nice car. It makes it unique, very powerful and on top of all that, fun.

Or are you just looking for more power? If so, i still think it would be much easier to just buy an STI for the money you're throwing around.

For an Engine+Tranny (DCCD)+diff, you'll looking around $6K at the least. (depending on miles) These are pre-recession prices, but it's pricey.

It depends what you want overall. There are some things to consider in this endevour. First off if you buy any JDM set up you need to realize that the bits were made for japan so you will notice little differences like shorter gears and a shift lever that leans to the passenger side of the car. As far as the motor goes. That is where I would ask what you want to do with the car. Yes the v7 is capable of 500hp and in some cases more. The early v7 came with big potted heads the later did not. The earlier v7s are the one that are real hartld to find. If you want a fun, fast spooling car the v8 is good. The v8 came with big ported heads and has forged internals minus the pistons which are hypercast. Which are more brittle than forged but stronger than stokers. The v8 pistons are lighter and spools faster and is capable of a safe 425 hp from what I have seen. But for power I would do v7 block with v8 heads. I am no expert but I spent some time researching this and this is what I found. Hope it helps.

Rally Stuff Do some more research on the differences on the V8 vs V7....

Once again good advise has been given, but a few details are off. The version 8 is the twinscroll god of these jdm options. Stock performance is better than v7, plus all v8 were bigport so no guessing what you end up with there. Plus you want to get the newest, younger swap you can, see when the regulations in japan make people pay higher taxes for higher mileage cars, they just beat the hell out of em as quick as they can then part em or sell em off to a parts house. Id rather live with the pistons of a V8 than a possible small port V7.. Find a good vendor, get the engine along with the down pipe, ecu, intercooler, and harness. Then look into the avcs wiring info on this forum or get a kit from IA performance. Drop it in wire it up and save for a clutch and tranny..

i answered my own questions. im leaning on the v8 because the transmission it comes with has dccd where as most of the v7 swaps are no dccd.

Don't know if you've done anything on this yet, but one thing I noticed here and learned from personal experience is that the JDM downpipe is shorter than the USDM. SO you either need a aftermarket downpipe or a full JDM exhaust.
