Ratio's of a OS Box with stock diffs are (8000RPM). 1st=87 2nd=138 3rd= 190 4th= standard (as it is 1:1) 5th depends if you have a stock ratio or not. I have a few photo's of when I put my box together that I will throw up for you tonight. I'm 99% sure there was a 'OS Giken' engraving on the heavy duty input shaft, none on the gears themselves. This is stretching my memory though.

That's bloody cheap! Nice score!

Not done yet, it will be tuned after jamboree. When I was there late last week the turbos and dumps were going on. Still had the clutch and box to go back in!

^^^ What Brett said. Having driven that same OS tripple on a RB 3.0.... DONT DO IT, C spec coppermix > Everything else for under 750 HP. (That owner is going back to a C spec Nismo for the new engine. I think that itself says enough) Injectors. Im running the ID 2000's in mine. Very happy camper.

That's what you do notice. That half to full throttle instant response. Well I use 'instant' very loosly with GT RS's. It was alot better with E85!

I suppose it depends on who tunes it. Im running ID 2000's (2225cc) and at 400rwkw im using a Duty cycle of about 63% IIRC (AFR's are about 11.6:1 Petrol corrected according to my wideband (Roughly .80 Lambda)). If you calculate that back thats just on 1400 CC worth of injector. Thats on a 2.8 with GT RS's at 1.75 bar. Its a little low as my exhuast was choking it like a whore.

It wont be that easy

That exhaust came off my car a few weeks ago. I can tell you it is for a R33 GTR.

Yep. Pull the shaft.

In before close!

Stock stroke? Headwork? If it's still stock capacity I think you would be better off with 9's and making a slightly lower figure. It's all good to say you want 'X' power, but when you get belted off the line by a much lower powered car you wont be happy! 2.8 to 3.0 with 5's yes 2.6... Not so much... Having said that it does depend on what you want from the car.

ID's. Do it!!!

Any chance of a engine bay shot Gav? I'd like to see how you have mounted everything.

What turbo's? -9's or twin T88's? What power are you after?

Ring Chris and ask him what he wants/likes seeing that Racepace is doing the work.

Put the stockers back on and put the money towards something useful!!!

It was an improvement yes. Either way the debate of 5's and RS's/10's has been had many times. Gav's result sums it up perfectly. Anyway, back on topic.... SS's and -9's wasn't it

It came off my car that night!!!! Lol. It was on my car for years.

It shall be. With nice and small cams (maybe the mines 252's @ 10.05mm) and 'tickled' -5's. Should be alot better than the choo choo choO chOO cH00 CH00 CHOOF CHOOF CHOOF I have now!

The sperm whale is still powered by RS's BUT I have bought a set of 5's to go on. Who can say no to 1000 RPM less to get to fullboost?

With the $662 (if you dont get hit with tax which normally you dont but who knows) you can go and buy yourself a set of poncams or some cam gears and a some cheap skank for the night. Funny thing is -5's come with a 15.5 PSI actuator for exactly the same price! If you wanna be a real hard arse you can go the -10's for $1633 each but they dont come with actuators. We all know what a awsome turbo those bad boys are!

12 weeks? Where did you get them from?

Thanks man!! Wheels are 19 x 9.5 + 12 with 275 / 30 x 19 bridgestones. Nismo S Tune suspension.

Oh. You missed out on the best day!!!
