Its a 240sx (S14), I'm either going to go KA or SR but I need the bottom end built to the gills on which ever motor I choose to build. Who builds reliable, meticulously crafted, measured down to the 10000th of an inch like an anal german motors around the A? I don't want to be on a highway run and have my shit blow like ... So I need a good builder. I want it done right the first time.

k thx..
