Does the knocking go away when warm? If it's present when warm and applying throttle you WILL have to replace it soon anyway. STi 2.0 swap? Lots of stuff, inc exhaust, ECM, etc. Get advice from an STi/WRX/GT pro.

@ernest yeah I know I'm going to have to replace it. That's why I'm trying to find out a good or the correct STI motor to put in it and I understand that I will have to put a lot of other things into it like exhaust, ECM and a bunch more fun jazz. Luckily my friend works at a salvage yard and I've built motors since I was young although they were all small block V8 builds. I was just wondering if there was a certain year of STI I should look for a motor out of that would crossover better than others.
