Mike, yup, I envy the room you have for turbos.
SnowRocker88, thank you for the offer. If you are so inclined, and you have a car to measure, maybe you could make some detailed engineering drawings of the engine bay, the stock engine (outline only on that), axles, rear crossmember, etc. If you posted them, it would help anybody doing future engine swaps. For my purposes, it won't be necessary. I am actually an engineer, but I decided that a detailed CAD drawing would not really help me. I could get bogged down just doing the drawing.
Today, I am feeling good enough to attempt to put the N* into my 91na.
Some things for people reading this to consider:
1) the Audi ABZ V8 is the same length, or in some cases SHORTER than Toyota V6's !
2) Look at side view photos of mid-engine exotic cars that have a N/S arrangement. Note the length of the car between the rear most part of the door sills, and the rear wheel well. Note the length of the nose of the car relative to that. You will notice that most mid-engine cars have a pretty long distance there, and a very short nose. The McLaren F1 has so much room there, that Gordon Murray elected to put side trunks (paniers ?) on the F1. The Ferrari Testarossa/512TR and F50 have the radiators in that location. The Pantera has a fuel tank there. (its a much shorter car than the McLaren and the 12 cylinder Ferrari's).
WHeel bases for:
McLaren: 105"
Testarossa: 102"
Pantera: 98"
I think the Lambo's are around 103-105".
Mr2 Mk2: 94.5"
