I was also considering making my hatch into a integra and just part out the rest of it but i dont know what i want to do!
motor will fit like it belongs there. the gsr and ls motor are identical in size. the only difference is that one has a stronger block and longer stroke and is none vtec. so everything fit perfectly. you can use the ls tranny you already have, that is also basicly the same as the gsr tranny. just that the ls has longer gear ratios. like most people are suggestin go with the whole gsr swap. its kinda stupid to put a non vtec head on a gsr block. thats like going the oppsite way from ls vtec. performance is going to suck. i suggest selling the ls head and buying a gsr head or b16(civic si) head. All motor mounts will fit too.. good luck.
