Hey whats goin on everyone...I am lookin to do some serious engine mods in the future and I need a little help. I want to spend around 2500-3000 on an engine. I am lookin to be able to withstand 400-450whp on the block prolly through a GT30R. I am thinking of buying an EJ257 complete engine or maybe purchasing an axis block. I just am not sure what would suit me better and what was easier. If i go with the aaxis block does that mate up with my stock wrx heads? Is there a lot of labor required to install?

I am open to all suggestions,
Thanks

Jimmy
