Get the crank crack tested, its simple.

There is no difference between the R32/R33/R34 cranks except for the oil pump drive on the R32 ones. Just get a collar fitted and you wont have any problems. Talk to Greg at Pro Engines (www.proengines.com.au). He makes the collars exactly the same as the JUN ones using hardened steel and only charges about half the price. The nose of the crank has to be ground down, then the collar is pressed on (using a 40 ton press I think it was) and grub screwed in for good measure.

The weakest part of the crank is the rod bolts. Use ARP 2000 rod bolts and you wont have any problems with it. As an example, I have been running over 300kw on an R32 crank (which is now 13 years old) for almost 3 years now. Recently had the crank out of the car and it was still in perfect condition.

You will be waiting a bloody long time for a brand new crank. Nissan JP dont even have any in stock, and they will fill all there back orders first before they even think about sending them overseas. Thats assuming they come back into production....

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      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 ne 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.

      Hey good to see you on the forums! Haha Considering this cars past with electronic issues I am leaning towards it being a wiring fault somewhere in the engine bay. When testing the ac relay in the fuse box there was no earth trigger. I am probably going to try "bench test" the compressor by giving it direct ground and power to see if i can hear the ac clutch click otherwise I will be pretty sure I have a dead compressor. If it does work then I will be tracing some wiring it seems.
