Os Giken 5 Speed Vs Ppg Straight Cut/helical Cut Dog Gears Vs Sequentials

[boobeedoobee]

Have you picked up the OS88 piggaz?

[Piggaz]

Nah man. Was ordered two months ago. I'm betting late February if delivery in Japan works well with the container it's being put in.

[R32 TT]

...come on mate...

[boobeedoobee]

They both have taller ratios.

Assuming a 265/35x18 tyre and stock ratios and a rev limit of 8000 RPM the speeds are as follow

Stock

1st - 75

2nd - 120

3rd - 180

PPG Helical and straight cut dog

1st - 89

2nd - 143

3rd - 189

OS GIKEN

1st - 87

2nd - 138

3rd - 190

Is the os giken speeds that you have showed are they the correct speeds even with the close ratio gear set? I would have thought that the closer gear set would shorten at least gears 2,3,4 and 5? Ow btw are those figures for a 34 ? Or 32 gtr?

The OS GIKEN 5 speed is most definately taller than factory gearing. That is assuming 4.11's in the diffs. Gts4 ratios will shorten that by 7% iirc.

[boobeedoobee]

Is it worth considering putting in th r34 gtr 6 peed conversion for my 32 gtr ?

[Piggaz]

What's the setup?

It would make the gearing awfully short with the 4.11's. You'd be changing gears like an Evo. It isn't the cheapest conversion to do.

[boobeedoobee]

Its from the nismo catalouge it's a 32 conversion kit comes with everything including a copper mix clutch for around 11k

[GTR_JOEY]

Like he said what's the set up?

[boobeedoobee]

Btw.. do you know if you can get the ppg straight cut box with 1-4 straight and 5th as a helical?

[Piggaz]

I asked that question. No go.

[GTR_JOEY]

I was quoting you numbnuts

[Piggaz]

I was talking about the straight cut/helical question.

[GTR_JOEY]

Well now we are both confused..

Or maybe just me

[levinboy]

Just you

[boobeedoobee]

Like he said what's the set up?

Set up is an r34 gtr getrag 6spd gearbox fitted to a 32 gtr .. it's the whole box including everything needed to do the conversation

By setup I meant what's the engine/turbo combination.

[BakemonoRicer]

Epic, great to see you're going all out !!

Hope to see your 33 in action one day Piggaz

[Piggaz]

Boobee. The reason I was asking turbo/engine combo is that (and this is my opinion only) the taller gears in the OS set make a lethargic bottom end of a 2.6 L engine and make it even more pronounced.

For example, a mate on here on a pretty decent R33 GTR put one in and ended pulling it out and going back to stock ratios. That was predominately a track car too. 2.6 with -9's and -5's at different points.

Just something to think about.

Bakemono. Cheers man . Be good to drive it again lol.

[XKLABA]

Oh the lols

only do the Getrag if you do the 3.545 diffs as well, 1st gear in my 34 is now and always was useless even when it was a 2.6 with -7s, so add 4.11s to that and you may as well stay with the 5 speed as you won't use first with the Getrag

I can't wait to see the difference between 4.11s and 3.545s with the two identical OS88s once put side by side
