Rebuilding 32r G'box With Osg 5 Speed Kit

[Ronin 09]

fark. what's the labour on the box?

[Mr. Keets]

From memory it was $700...but don't quote me. Plus I want to put more clutches and floaters on the transfer case and do the rear diff

[Piggaz]

Well seeing that i smashed my box on saturday this OS gear set is looking like a very nice option. A few questions... Seeing that greenline have the 5 speed set cheaper then the 3 gear set... can i order the 5 and just replace it with my stock 5th? What speed are you doing at 8000 RPM with stock 4.111 diffs in each gear?

Paul.... any issues with it?

[Mr. Keets]

Not sure about replacing the the 5th gear with an OEM, but I don't why you would unless your heading for a land speed record. Looking at the ratios I would expect the OSG kit would be pretty handy for the drags. Sorry I did the calcs in miles. Still in the drag racing mind set I guess

OEM gears with 17inch tyres. 8000rpm

1st - 47

2nd- 78

3rd - 116

4th - 151

5th - 201mph

OSG gears with 17inch wheels. 8000rpm

1st - 56

2nd- 89

3rd - 122

4th - 151

5th - 182mph

What tyre profile is that based on?

Only reason being.... driving down the freeway at 120km/h theres no reason for the motor to be spinning at 3600RPM (or close enough to it). If anything i'd want to make the 5th taller.... it has enough grunt to push the tall gear.

From memory it was a 45....bugger I need to do the calcs again lol

Fair enough. Hopefully someone might have the answer to the 5th gear question

34 box would prob be nicer for best of both worlds, closer gearing for speed and tall 6th gear for cruise...

5th gear in the OS is a 0.826 compared to a 0.752 STD so not ideal for a highway cruiser

I no longer own my box as of today...she served me well and it was sad to see her go....sob...

Fully optioned PPG straight cut dog box going in though... it was a sensible upgrade as i was really testing the OS's limits.

I looked at that option but the number of posts referring to rebuilds scared me off. I'm planning on a 2.8 stroker next year so I thought i'd pass on it

Paul, With the sort of work your R does I'd be looking at the dogbox too...9 sec pass, nice one . My R will still see the street more than the track for now but it will eventually become more track than street. Do you think it's possible to use the standard 5th gear with the OSG kit?

i did all of my 9 sec runs only using 3 gears...so yes 5th is not needed...either is 4th..lol

keep std 5th as it will be a better road car...its on the other side of the sandwich plate so i cant see it being an issue. Ill check with Terry (Award Diff and Gearbox) on Monday for you as im no gearbox expert (its white mans magic).

as for the r34 box comment,

its 6th is not very different from a 5 speed's 5th.

and the 1/2 are rather short

Thanks for that

[Swiper the Fox]

Thanks for that

Right...the answer is the following and i will quote the ever helpfull Trish..."you buy the 5 speed kit which includes all gears and the uprated input shaft and you dont fit the 5th gear. You can then use the 5th gear for whatever you want...you could make an ashtray out of it, you could put it up a flagpole or whatever you want with it" end quote...lol

they copped about 4 phone calls from some impatient people today wanting to know this imformation, but couldnt wait for me to post it here.

^^^ Excellent. Just what I was after. 5 speed kit here we come

Paul... in your box did you use the OS centre plate?

[Angus Smart]

A 5th gear cock ring would go down a treat!!

No the STD sandwich plate was used in mine.

Andrew id say a 5th gear cock ring would become a 5th gear ankle bracelet over time...lol

hahaha not guilty. Thanks Paul ...OEM fifth cog sounds like a plan. Anyone know if I can use an OSG 5th cog on a 1989 HKS flag pole or do I need more parts???

No..No, I don't think I'll be doing that; but thanks for that disturbing yet inventive suggestion

[Mr. Keets]

Well my mate back home opened up the goodies...

Here's the gear set...porn! Please excuse the frangipanis lol .

and I got some decals...woowho

...and this is a parts list. Anyone hazard a guess as to what the non Part numbers mean and which parts go with what box???

[9krpm]

If you take the car to the circuit, I think it would be wise to upgrade the 5th as well. I use my OS 5th gear a fair bit on the track. It's not that bad on the highway.

Don't waste a well made gear.
