hey guy just need help or suggestions with my wiring/engine. i have a vl calais with an r34 neo engine and manual box. bigger turbo, bigger injectors, aftermarket greddy plenum so wiring also dosnt fit. have standard computer etc. spent ages wiring up as loom was cut in several spots. managed to get it to a stage where it was cranking but would fire. had no injector pulse or spark. cas is new but had to use harness plug from rb 20 to fit. after a few weeks of playing got over it and ripped whole harness out. ive heard ill need and aftermarket comp anyway and also heard that rb25 wiring will fit just will have to use r33 aftermarket comp such as apexi power fc? so what do you think i should do. either go with that set up to save dramas or send my harness out somewhere if possible to be wired up correct. any help would be appreciated as ive searched heaps of places and sites etc over the last few months. all where helpful but not mush info at all. cheers
