Ffs. If my laptop didn't die, I had all the parts listed for the OS 5 speed conversion.
Basically what you need is all the Series 3 synchro's, balk rings and whatever else. If you dig around hard enough on the forum, I'm sure I've posted it up.
The smallest you can go in a -5 housing is a 63 mm GTX wheel UNLESS you put a sleeve in the housing. The -5 wheel at some points is larger than the 60 mm GTX wheel.I believe "meathead" was looking down this avenue with the 60 mm in -5 housings.
It's been done many times.
GCG also told me that my -5's couldn't get orientated to suit a stock position GTR. Sometimes I think they would be better suited to sell shoes.
You still haven't answered the questions.
How much power are you after? This will determine the pump size and to some degree the size of the tank needed!
A rb26 should not go back in it's hole without a real front diff IMO. One of the best mods I've done to date. Totally transforms the car coming out of corners.
Have not seen a result yet, but the 6062 is rated at 750 hp and the 6262 is rated at 705 hp.What that translates into real works figures, who knows, but it's definately interesting. Smaller front fan but can flow more... Win win!!!!
