ok, lets start.
This swap took me the better part of a year. I got the engine off a louse that owed me money, so i took his engine, but it came from JDM engine depot originally. Things to replace: The clutch, any sensors you can, the Igniter(BIG), z32 fuel filter.
There is a lot of fab work to put this into a z31. i made the engine mounts, the trans mounts, the downpipe, the intercooler(really just modified)
If you don't have an engine level, get a shop to put it in for you. you want as straight a line as you can get between the crank and the diff. everything level, so you don't snap things.
however, i'm a wiring guy, always have been, and i had to call in a friend who runs a shop(slidewayz motorsports) to help me work out some of the wiring. i moved things around in the engine bay.
I had to cut the front rad support out and make a bracket that goes across and holds the rad.(it's further foward allowing for more room between the engine and rad) and use a lowpro fan, and i still can't get the waterpump pull off without taking the rad out.
it's a hell of a lot of work, and it's far from finished. i just picked up parts today to make a real overflow bottle.
The gauges were easy, i took the a-piller off and used the "dash mount" kit to attach them. luckly the a-piller pad has a small sheet of steel in it so they are really secure.
the ones in the center, i wrapped in electrical tape until it was thick enough to shove in the hole and wouldn't fall threw, then i put a little more, and really gave it a good push so it's stuck.
the headlights came from
http://www.norcalmr2.com but i have the parts to do a front kouki conversion, so i don't know how i'm going to do that., probably take it apart and try to fit them to the new bulbs.
Where about do you live?
