After going through three 2.0l blocks and building one of those up, I decided I wanted to go 2.5l after all.
Recap on previous 2.0l build:
The first few used 2.0l blocks were to f'ed up to build. The third block was in great condition and just had to get bored .020 over stock. I bought a set of Wiesco forged pistons and had them fit to the block. After I had all the pieces to make the block complete, I got a ride in a stage 2 STI and the low end torque was so much fun that it made me sell my 2.0l block and persue a 2.5l build.
I have a set of bare wrx heads that I bought a year ago that have been cleaned and checked for cracks, and they will be used for this build. I just landed a nice used 2.5l STI block for $400, but I need to travel a few hours to pick it up. It has no problems like spun bearings of broke ring lands, but I plan on tearing it down anyways to have it checked for cracks and machined. I am planning on using forged pistons and rods to handle 400-500 whp. Whether or not the block will last long at those power levels is a different matter.
For head work, I am not going crazy on porting or polishing, just a nice valve job with .5mm over valves. Cams have not been decided, but will be at least 272 duration. I'll post pics and updates along the way.
