i have a 94 prelude... so i hopefully wont be putting a b series in it. i will be building a h22a vtec for the n/a set up for my lude. a type r throttle body will fit a h series motor? woudnt preludes, due to having a larger motor then the b series motors, need a bigger throttle body even for a n/a set up? i have heard really good things about RC injectors. what is the purpose of switching out the throttle body for a larger one or even a different one then the stock. 240cc.... the stock amount would be sufficient for an n/a set up when it comes to injectors? i know that i have seen an h23a set up in a prelude running 720 cc injectors but he was turboed.
