Thats pretty impressive. Ive got an rb25 in my r32 so im no stranger to the 33 powerplant. Im hearing a lot about leaking BOV's I have a turbosmart v-port and I reckon its leaking. Do you no how to check for sure. Also having probs getting the spark plugs right. They are gapped 0.8mm NGK platinum. I reckon these are rated to hot for my motor cos it misses, especially as you wind up the boost. If i get this stuff right i should be able to do twelves no probs.

The heat range for the stock turbo is 6's or 7's. Gap 6's to 0.7mm or the 7's to 0.9mm.

It's easy to check if its leaking, because you will be able to hear an air leak at idle from there. Under boost the 'leak' is if the boost doesn't hold from early on in the peice. I reckon it's probably not leaking tho'.

If the motor is in good tune I'm sure you will do a 12 sometime. What has the car done so far?

I havnt taken it to the plex yet. I want to sort these issues out first and also some treads to hold to back end. I have the 4.3:1 diff ratios because it is an r32, and the extra torque low down from the rb25 means my first gear goes up in smoke with no chance. I cannot get first gear down on street tyres. Second isnt much better.

      RH9 R32 GTR Build Thread

      Out of curiosity, how do you cover up the inspection hole? Surely it doesn't sit open like that, right? With grime and dirt coming in and oil going out?

      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
