1j conversions depend on a whole bunch of things. Amount of half cut (my friend used a jzx81 from a chaser cost about 2300 i think) exhaust, wiring, and a few extras. it bolts up to mounts ok its just the wiring thats a little bit fiddly, plus some of the sensors can be a little tricky as well, i'd speak to an engineer first, before i start buying. if you need info i can get him to contact you.
