Kel. You need to do a good search as there are differing opinions in regard to the way forward depending on application. I have an OSG 5 speed kit that, but for a small annoying vibration believed to come from a selector fork, is fine. There are a variety of choices beyond that including buy a replacement Nissan 5 speed.

400kw daily driver or 400kw track car?

A daily driver I think you can get away with running quality trans fluid like Royal Purple, Motul, Redline etc.

As for track car is another story, cheapest option would be to just keep buying nissan 5 speed as they die, since even replacement gear sets by PPG, OS Gilken etc aren't invulnerable.

It would manly be a daily driver maybe getting on the drag strip every now and than there's no circuits around here so it would be use on one of them really just the street ive got redline shock proof gearbox oil to put in it my mate said it was the best but still don't want to destroy the box and have to replace it. Also if i go a ppg or OS Giken gearbox what sort of gear box (dogmesh?) I still want the driveability of the factory gearbox just want to know it can handle the power.

Cheers Kel

    • Took a little trip  went to nismo hoping the get my fuel tank hoses and unfortunately they told me they didn’t have stock luckily I was able to go to a Nissan parts store and they were able to order them in for me  then can home and cleaned the tank with some degreaser and fitted the new hoses before putting it back in the car 
    • 100% I’ll hack into the 33. Strap a turbo onto the RB25DE and/or put the 25 head on a 30 block. 33 passed in cos the reserve was too high. I’ll try lowballing it again and negotiate. Aim is to have it landed and on the road for under 15k, then spend the same amount on top in mods.
    • It's generally best practise to run 1x run without VCT enabled, then 1x run enabled till redline. Overlay the two torque graphs and you'll find the desired RPM to turn off VCT. Sometimes, it might be even worthwhile turning off VCT earlier control torque/cylinder pressure and using VCT purely to spool the turbo.
    • They sell them in Malaysia for about $4
    • First time I ever have issues with Amazon, but my wife often tells me to keep an eye out for fakes. It finally got me. I wrapped up the conversation with Gates. The gentlemen I was talking to seemed to hate his job but the response time on their technical support is outstanding. He stated that the hose is marked with some variation of "SAE J30R10" but that if you only purchase a 1 foot length like I did, it is possible to get a cut between markings and have a blank hose. To no ones surprise, he stated the swelling and "gummyness" isn't normal and to replace/buy from somewhere else (He mentioned NAPA). I'll toss a small end of the new one in gas for a few days before pulling the hanger out again, just to be safe.  Hose should arrive Monday. For those running multiple pump in tank hangers, you know the joys of getting them out and back in. I'm surprised I haven't destroyed my level float yet.  Lastly once I wrap all of this up, I'm planning on hitting the dyno again in 2 weeks while I'm on vacation. I realized recently that my VCT is set to turn off at 5000RPM. I'm surprised it wasn't increased while I was on the dyno last. I'm expecting I can increase it to ~6500RPM, if not more. Should hopefully get another 15-20kw out of it. I also want him to revisit my knock thresholds. I'm occasionally getting false knock around 3000rpm.
