Looks like I need to pick up a coupe shell and build an R13 with skyline body work if I want anything close to an "easy" r32. Which would really only leave me with a firewall and green house (glass/roof) as an s13 heh. I wonder if that would be lighter then a regular R32 GTR?
Its not technically legal as you altered the engine, and it wouldn't meet federal emissions standards unless you tested it to meet emissions standards. This is a tough law to enforce, you won't see many people getting busted ONLY because of this.

Its a strange spot, the whole self assembled/ kit car thing. However Kaizo had a lot of problems doing some similar things.

Rb25 guys run any Z32/J30 ecu to use nistune, and still be able to use their VTCs, as all of the ecus are exactly the same, they just have different tunes. So all you'd have to do is get a 95.5-96+ ecu and install nistune with the rb maps you need. For the actual OBD/emission requirements you could just get a used Z32 EGR valve and weld it into the appropriate places and copy the emissions canitser vacuume routing. For people that get their hands dirty wrenching it shouldn't be that hard, just some know how and diagrams.
It can, its been done. However, the system is a little more complicated. How about misfire detection? Tank pressurization/leak detection? Just making it work is the EASY part of the OBD II system, it would still need to be certified, in Ann Arbor, in front of the EPA. A 1996 Z32 ECU is a very, very basic OBD II ECU. Back in 1996, even the OEM's had problems with the standards.
If you have run a GT-R on a FTP dyno as many times as I have, you will start to understand some of the issues associated with the RB26. Its an engine from an earlier time.

I was one of those "Motorex pricks". Here's your answer. The NHTSA, DOT , OVSC, saw all the models of cars, and asked Motorex what we wanted to test. 1995 Dual Airbag R33 GTS. If it were your money, what would you pick to crash test? Single bag self contained R32 , nearly new R34? The NHTSA DOT, reviewed the Motorex/JK conformance package, and crash testing results for months prior to allowing the first bond release, incidentally on an R32 GT-R. I have been to Washington DC three times to visit the OVSC, to show them what we were doing at Motorex, and offering them the opportunity to come out and check up on what we were doing in 1999-2002 when I left.
If you ever get to see and work on R32, R33, R34 GT-R up close, you will realize they share much more in common than differences. The OVSC changed their mind on what they approved, because of Hiro's inability to actually get the cars done, and getting lazy on the actual certifications. The OVSC allows cars, car models to be certified under "substantially similar" to an earlier or later model. Fenders, lights, hoods, and bumpers are generally not regarded as "crash items"
Right about now, Nissan Skyline is a dirty word at the OVSC.
