R34 Neo Into R33 Series 2 Conversion Advice

[gt35slider]

Hi everyone

i have a r33 rolling shell missing engine, gearbox and harness. I have just purchased a r34 crashed with the neo mtor. Now i have been doing research but i am wanting to use the R34 harness in the 33. Can someone please give me some guidance as alot of the threads are bit all over the place.

also can and aftermarket plenum from the older 25 go onto a neo head, they have the same intake manifold gasket, any help in regarding this conversion will be greatly appreciated.

Have a look at my thread, mine is running but with all S2 R33 wiring. There's a bit of work needed to splice the 34 engine loom into the 33 body loom. 33 wiring was the easiest option.

Yeah, can run aftermarket inlet manifold for non-Neo RB25's on the Neo.

Um....you have no loom in the R33. The only sensible option is to use the R34 loom. With the engine out you can make the various changes more easily. You might want to buy an R33 loom to be able to obtain some of the plugs.

I did Neo into R32. The Neo loom went in, having had all the mods done on the bench beforehand. Sure, I got a guy who knows what needs to be done to make all the mods, but you could do the same.

Here's my thread. Was easier for me since I already had the engine loom. Didn't consider splicing the looms because I couldn't find any info regarding wiring so just stuck the with R33 engine loom.
