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....

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
