So I have been accumulating parts to turbo my BD9. I have my exhaust, crossmember, turbo, and all related parts to basically turbo my EJ25D. I know, it wont handle it but thought it would be a fun ending to a 300K 25D.
So here is my question...
I have the blown JDM EJ20H in my GT-B, with a spun bearing that will be pulled here soon. Built as a single turbo.
I also might be getting a USDM EJ205 (I think, I'll correct this if needed. Stock motor for 04 WRX) with a bad bottom end and bent valves.
My question is, what one would be better for building? I'm looking into forged pistons, rods, maybe even build a stroker and bump it up to a 2.2 or something.
Engine management is also part of the question. I would like to run it all on the USDM WRX ECU and just have it tuned. Would this work for the EJ20H or would I need to get a Vi-Pec system of something like it?
Ultimately, I want this motor to take what ever I toss at it, like 500hp type of stuff. Not that it will get that crazy, but I want it to handle it.
Now I dont want bias opinions for one over the other, but I do want valid and complete info. These are the only 2 motors available to me at this time so no other motors are an option so telling me to get an EJ20G or a EJ207 will not help me at all.
Thank for the help guys.
