1990 r32 gtr runing 550bhp at low boost 630-700 on high boost just had trip plate clutch fitted and shaged 3rd gear . should i replace box with standerd one and keep my fingers crosed :? or uprated 1st 2nd 3rd gear kit or new uprated box

There are and have been several 600+ Skylines* running around on standard boxes for years, it seems to be down to how you change gear rather than the power although I guess luck comes into it too.

The 1,2,3 gearsets are supposed to be very good though but justifying the cost is something only you can decide upon. You could do a lot worse than PM max1. He knows the intimate details about R32's and killing gearboxes first hand.

Best of luck. Me? I would keep using standard boxes, don't rush the shifts and put up with the bill of a used standard replacement as and when, but then I'm on a budget. If your pockets are deep enough then buying a seriously uprated gearbox can always be sold seperately in the future offsetting some of the cost.

*Rocket Ronnie used a standard box for a couple of years and he was blessed with mucho BHP.

What kind of boost difference are we talking about to have a difference of 150BHP between high and low boost!!?

Do you use it on the drag strip or what kind of use are you doing?

car is aimed at track use however went on the 1/4 was dynoed at apt at 554bhp 0.9bar but i have outher dynos at 1.2bar showing 630bhp so i guess if it was put to 1.6-1.7bar( which i would not do) Maybe upto 700bhp :!: so what gearbox :?:

thanks for the imput spoke to R.K TUINING ( recomended thanks you know who you are) got some good advice, triple plate clutch big bhp and 3rd on a standerd box dont work week point. think i have found box with giken 1-2-3 going to pick up tomorrow and straight down to R.K who will tell me if its what it says on the tin :!: Fingers crossed. This is starting to get costly could have run my 442 cutless for a couple of years now 8mpg
