Intro: just bought a 2002 WRX wagon 133,000 miles, with rod knock for 4k, with 5k left to spend on the repair. If I do it in my own garage. . Though Iíve never done a Subaru, I have done plenty of builds in the past, and am fully excited and capable of doing the swap in my garage ďI believe.Ē
To build a good gas mileage high performance bug-eyed wagon. I donít need 100,000 horsepower to take corners and get to my climbing spots.
With a stronger then factory engine, with slightly more off boost acceleration. That still gets closer to 30 mpg. CAN it be done??
Been looking into a 2.5 block from Import Image Racing Your Online Source for Aftermarket High Performance Car Parts and Accessories for Subaru WRX and STI, Nissan, Mazda, Misubishi Evolution and others. with forged pistons, running roughly 2800. Maybe top speeds ss1? And also their head work for around 400. Plus maybe some springs.
Also, Iím not planning on doing cams in this swap. Would I still need STI or equivalent injectors and a 255 pump?
Or can I use the stock ones and still get decent AFR? With a mild, still close to stage 2 tune. .
Then when I want to up boost, maybe upgrade fuel. I do have money to do both though I believe
Any! Advice would be appreciated.
