So im doing a High compression build that so far consists of ej253 block with Phase 2 2.2 heads. im having both heads and both block haves milled 10 thousandths over so there should be a bit more compression there too. I have a set of delta 2000 im tossing in as well. my question is i have a set of 630cc injectors just lying around right now and would like to know if those would be too big to do an e85 conversion with. Or should i just stick with the 91 octane on the stock 2.2 injectors
