NEED HELp W LSV SWAP.

[94honduh_LSV]

Ok before I make an ass out of myself I want to say I'm new to this Honda scene. This my 2nd Honda. I had a civic in high school bcuz that's what I could afford but never did anything to it, just changed oil nd put gas in it. Now I bought a 94 integra LSv with a b18b, The guy I bought it from did a few things to it, stock bore w type r pistons nd rods, cam gears nd 98 gsr head. The miles on the engine are unknown so I can either sleeve it to 84mm nd bore nd hone it nd my question is I found a b18a brand spankin new in the Honda box box but It it's from 90-93 Ls teg. Can It fit in my car? What would I have to do? I would put the gsr head on it? Bcuz this project is for boost. I recently have been saving for a while nd have about 10 closer to 11g's. I'm looking around 350 to 400 hp, Once i hit those numbers there's no more up grading. I'll be satisfied with those numbers for good! Thanks for any help guys I really appreciate it!
