This is what a 500 dollar BMW looks like. It's grey, not green. The sparco seat is not mine. It's grey, not green. There are a few small dents and a little bit of rust that I will take care of when i paint the car. Today I am removing the dash and all the underdash components. I am rewiring the car from the driver seat forward. Originally, I was going to keep a full interior. After examining the car, I've decided that I am probably going to do a gutted, or at least "semi gutted" interior. The fitment is going to be tight, but i took some basic measurements.

The frame rail width on the skyline and BMW is 27"
The distance from the firewall to the rear of the cross member/swaybar is ~8" on both cars
The distance from the firewall to the front of the cross member/swaybar is ~16" on both cars
This is the tight one: the Distance from the firewall to rad support on the GTR is 40", while the same distance on the E30 is 33". EEP.

However, the RB26 is 31" long, back of engine to front of crank pulley. The skyline radiator i have is 1.25 inches thick. This leaves 3/8 of clearance front and rear. Since the motor does not torque in this direction, I think it should be alright. If not, I can get a narrower rad and put it UNDER the rad support. (stock location is aft of it.)

The brake booster is definitely going to be a problem. To a lesser extent, so is the downpipe (damn LHD cars).

I've already stripped almost 100 lbs off of the chassis in the engine bay alone, and another 100 lbs+ off of the rb motor (PS,AC,Front dif, Twin turbos and cast manifolds)

This is my tentative plan for construction:

Strip Body
Mount Engine
Build Exhaust and IC plumbing
New brake booster or remote mount
Build/buy driveshaft
Remove engine and all components. Strip to roller.
Shave firewall and enginebay.
Body work, paint, wheels
Paint engine covers, replace timing belt, thermostat and water pump
Reinstall engine and all plumbing
Rewire front half of car. Gauges?
Install race buckets. Possible bolt in cage.
Tune.

Mods:
RB26
GT35R @ 18psi
38mm tial WG
FMIC
Tial 50mm BOV
PFC or AEM. Ew. $$$
Seats?
Cage?
