You have to be careful about changing the ratios. I believe a stock R33 GTR has 4.11 gears. I think that the GTS4 has 4.30.

My GTR ended up having rears at 4.30 and fronts at 4.11 - and that stuffed my transfer case real good. I had to change it out to get it back to stock. I had a shop do it. Rear would be relatively easy. But the front is a real bear since it is attached in the transfer case and oil pan.

the only real viable option is r32 GTS4 gears. 32 GTS4 is actualy 4.375:1 and yes you need both front and rear crown wheel and pinions. they are a good upgrade from the GTR 4.111 gears. and they are not easy to find!

ah, well if you want to go that way then R34 gears are the way to go. but to be honest most people want more acceleration/less top speed. going to 3.9s will give you more top speed but cost you acceleration. considering with the stock gearing you can get to 300km/h (which without decent power you'll never see on any aus track) then i'm not sure what you want to make it even higher still?

you may need to confirm though that the 34 crown wheels and pinion gears will work with your 33 diffs. i'm not sure as I've never heard of anyone actually wanting the 3.9 gears. unlesss you live neat the autobahn and want to play with some ferraris and lambos!

i'm go out on limb here here and guess he's after highway economy. not everyone is after crazy acceleration. i've had the same idea

I'm getting a 3.6 final drive put into my R34GTT, I do HEAPS of highway and freeway driving, so I can justify doing it... I'll find out how it goes when I pick it up tomorrow.. :blink:

Hahaham I've been to a few different websites, and I've recovered a range of 'different' final drive readings:

3.55

3.545

3.369

3.27

3.266

I'd like to know, which bloody one is actually correct... :blink:

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
