I have been driving my hybrid (ej257 block & 2.0 liter heads) bugeye for about 8 months now. I went this route because my wrx engine broke and I needed to rebuild the 2.0 or just go with a 2.5. I have been concerned with issues relating to the compression and overall of having an engine that wasn't engineered by Subaru. Well I just ordered a set of STi heads and I'm hoping that it will give me piece of mind. What else will I need other than gaskets to make this work? How should I control AVCS?
I have contemplated getting AEM EMS or Hydra if I'm able to sell my AP, wrx heads and a couple of other things I have laying around. I have heard that I can disable AVCS, but I'm not sure that works with my longterm plans. What else will I need or need to do to make sure that I won't blow up another engine and that I will have good factory like power?
Thanks for the help.
