most 5spd front clips come with r154 handls like 900hp so there should be no problem
as for wiring there is a guy on ebay by the name of phoenix tuning or sumthin he does the wiring as long as you have all the wires.
2jzswap.com has all the neccesary items
i recommend some fat tires on the back as well 240=tail happy
and of course start out with a clean body. i reccomend one without rust at all check shock tower, front and rear wheel well, driver side engine bay frame rail as they rust the most there mainly because of exhaust hear and moisture sitting there, hatch doesnt matter and trunk also under battery is where there is alot of rust. check all those areas before swap, oh and all along the bottom. also make sure there is no bubbles on body or frame as that means it might have rustunder it. i had 3 240sx hatches and only 1 was truly clean. so look before you swap. have fun:biglaugh:
nm go to dr.tweak for wiring i think.
