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.

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.

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.

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.

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 :D. Be good to drive it again lol.

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 :D

    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
    • Welcome mate. Any pics? Even with a DE I'd be well happy if I had that as a 1st car.
