I bought the block and head with full internals both manifolds and a complete wiring harness for 100 dollars, not that bad. I am wanting to go with forced induction as soon as I can so I am going to build the b18A and just switch the blocks out. Its really hard to find information on what problems I will run into like what ECU,injectors and any other wiring or concerns I'd need to know about. I've tried searches but not much luck. I just got my eagle H-beams monday so I am kinda already into the project so any help would be great.
