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.
