Hello gentlemen,

Being that I am new to the forums, I'll start by introducing myself. My name is Kian, and I'm located in southern California. My friends and I are car nuts, everything from imports (like my Impreza coupe and Legacy GT) to an SR20 swapped 240z, to a custom supercharged Lotus Elise, to american muscle (well, a couple friends like them...) and we tend to wrench on some pretty fun cars (for what we have available to us in the states!)

To get further to the point, we are in the process of swapping an RB26 TT from a 1999 R34 GTR, into a 1998 R34 GTT which originally had an RB25 single turbo (as I'm sure you are all aware!) We are keeping the rwd transmission, and all the stock (GTT) accessories otherwise. I am in need of wiring schematics (in english) for these two models. I know how to handle wiring conversions, as we have had to do enough of these for various hybrids or subaru swaps, but doing it without the diagrams is not something I'd like to endure.

Any and all help is greatly appreciated.

Kian

      Mistakes were made, my R34 Story

      By The Bogan · Posted

      Lucky pick up Best to find these things before something horrible happened to the yoke flange thingies I would hate to think what would happen if it dropped the tailshaft  Hopefully the holes are not flogged out in the yokes and it was just the bolts that got munted  As for the hand brake.....ouch, look like the disc got rather hot, and I assume smokey, I recall when I had a front caliper seize on the Commodore, there was lots of smoke and the disc was glowing cherry red when I was able to eventually stop and have a look, and stopping a big heavy car, going down a big hill with some rather high RPM down shifts and some hand brake action is something that makes you think hard about life

      One of the things that never seemed right was the handbrake. Put in some nice new Project Mu shoes. We figured the rears were out, so why not. We're right there. My handbrake never worked well anyway. Well, this is them, 15km later. 67fdcf94-9763-4522-97a4-8f04b2ad0826.mp4 Keen eyes would note the difference in this picture too:   And this picture: Also, this was my Tailshaft bolts: 4ad3c7dd-51d0-4577-8e72-ba8bc82f6e87.mp4 It turns out my suspicions that one side of the handbrake cable was stretched all along were pretty accurate, as was my intuition that I didn't want to drop the tailshaft to swap them on jack stands and wasn't entirely sure about bolt torque. I have since bought the handbrake cables which have gone in. I'm very glad that I went to my mechanic friend who owns an alignment machine to get an alignment before the track day, because his eyes spotted these various levels of "WHAT THE f**k IS GOING ON HERE?". Turns out the alignment wasn't that bad, considering we changed the adjustable castor arms out for un-adjustable castor arms, and messed with the heights. Car drove pretty good with one side of the handbrake stuck on, unbleedable rear brakes, alignment screwy, and the tailshaft about to go flying and generally being a death trap waiting to happen! (I did have covid) (I maintain I adjusted the handbrake correctly, but movement caused shennanigans and/or I dislodged the spring on the problem side somewhat, or god knows what). G R E G G E D

      Very interesting, im not sure how all those complications fit in to running a haltech instead of a stock ecu but I'm starting to think I'm a bit out of my league.

      I just put 2 and 2 together. This is a Neo converted R32. The Neo ECU (in concert with the R34's AC controller) runs the AC quite differently to how the R32 ECU and AC controller do it. If you just drop it all in, it won't work. There is some tricky wiring required, including changing to the pressure switch that the Neo controllers want to see. I don't know what it is, because mine was done by a guru. It was a year or so after I did that transplant before he worked out what needed to be done.

      Don't assume the AC relay signal from the ECU is +, some models including Stagea use an earth trigger.
