Hi everyone sorry to ask a silly question but, I’m looking for an rb30 crank bolt however, being in the US it makes it pretty difficult and arp bolts are no where to be found. I do have an arp bolt for my 26 and was wondering if I could use it if I tap the crank. The thing the bothers me is the length of bolt. Do you all know the length difference?

Tap the crank ?!

The thing that should bother you is the fact you want to weaken the crank to use a stronger bolt.

Platinum racing on their US site have an M16 ARP bolt that is compatible with RB30.

Though that is true I can’t find the washer :(

I ordered a RB20/RB25/RB30 12 point ARP crank bolt from Platinum Racing. I plan on just using the stock washer. Anyone know the torque valve for the ARP bolt? I know the shop manual is 45nm/330 Ftlbs. With the ARP bolt I feel like the torque value would be less. I searched everywhere here in the states and had to order it from PR. They are very hard to come by here.

Pretty sure that’s the rb26 torque spec, the rb 20/25/30 is a lot lower

I'm confirming this. If my memory is correct, I believe it was somewhere around 240ftlb's.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
