R34 Gt-Four Engine Swap

Hey, helping a mate do an engine conversion in an R34 GT-FOUR. Initially thinking of an RB26 or RB30/26 swap but the big concern is the level and complexity of the re-wiring that might need to be done to get the 26 loom spliced into the 34's existing loom.

We want to have the car off the road for the minimum amount of time possible.

So queries are:

· Would we be better off ripping the 25 loom out and replacing with the 26 loom?

· Can we somehow use a mixture of the 25 and 26 looms?

· Or should we instead go with an RB25 or RB30/25 so that the wiring should be easier? On that note, is there a huge amount of difference in the wiring looms between the 34gtt and the 34 GT-FOUR (i.e. non-turbo)?

Cheers,

Peter

Not a big concern. People can install 25DET neo into an R32 and use the RB20 loom with a few simple modifications to the loom AFAIK

I dont have the info for you but if this thread goes unanswered after a few days i would suggest posting this thread in the forced induction section and you will get the answers you seek. Also there may be some threads that already have the info you need hidden in the depths of this site.

25 is easiest.

but yes you can use your 25 loom for the 26 conversion, bit of splicing and dicing to do.

just download an electronics pinout for the rb25 ecu and then compare it to a rb26 one. then re arrange the wires accordingly. might also need to check the voltages for a few small things.

      RB25DET with solid lifters - which cams ?

      They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required.

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?
