Gts2 Manual Gearbox

[eightsixboy]

Hey, can someone please tell me or direct me to any info on what manual gearbox is in a gts2?

I have been told that the gts2's ran the same box as a r32?

I have already bought a friggin standard r31 box as the gearbox place told me there all the same, but i have just been told that the gts2's had the same box that was behind the rb20et.

Any help much appreciated.

Hey Paul,

It's Adam here from Status

If anyone can shed some light on this scenario it would be good, as we were under the impression all R31 Skylines ran the standard VL/R31 5 speed (haven't done a GTS-2 before). Do you mean to say the RB20DET or the VL turbo RB30ET? Give us a call if you want to get your original box reconditioned, but if it's the VL turbo gearbox then I warn you in advance it will cost significantly more to recondition (depending on problems) as the internals are harder to source and more expensive. If it's the R32 gearbox then it will only cost a bit more than an R31 box.

Apologies for the mix up mate (for anyone reading this, we did give Paul a full refund on the R31 box).

Hey Adam, glad to see your a fellow skyline owner .

I had a look at the number on the side of my gearbox and it was RP71C #1 which was the same as the box you gave me. So I'm just wondering if you could check what number is on the side of the r32 box you have there (i think you said you had one).

From what ppl have been telling me the r32 box's had RP71C #2 instead of the #1, don't know what the difference is, i can only assume its just stronger or maybe even different ratios. I think maybe my box has been changed at some point with a normal r31 box.

I'll give you a buzz later this week. Thanks for your help to btw.

A series 3 R31 runs a box pretty much identical as the R32 RB20det box except for the second gear synchro(single VS dual???). Series 1 and 2 R31 box's are different too series 3. A GTS2 is a series 3 R31, so following that logic, the box would be almost identical to an R32 RB20DET box.

Suspension wise they had a floating front hub arrangement with larger calipers, and 100mm bolt spacing instead of 90mm, these GTS/HR31 struts are desirable for brake upgrades, or for datsun coilover conversions. Some GTS's had a factory camber/castor adjustable strut top. The rear brakes were as per standard IIRC. They had factory bilsteins, better seats/interior, factory bodykit, ECU chip/remap, stainless steel exhaust and possibly a different cam. GTS1's are all white, GTS2 are all RED.

That is all from memory, go to www.r31skylineclub.com for more info. http://wiki.r31skylineclub.com/index.php?title=R31#GTS2 no mention of a different box

Is there any difference in gearing between any of the r31 box's or is it just strength wise. If there is no difference in the gearing then it wouldn't matter what r31 box i put in my gts2 cause strength wouldnt really be an issue cause its only n/a.

I seriously can't believe how hard it has been to try find out what box should be in my gts2. On ebay there is a rb20det box listed, i asked the guy what number was on the side and he told me rp71c #1 where as i thought it should have been #2. The box in my gts2 is the #1 so i have no idea what it is.

I don't know if i should just chuck in the box i was originally going to put in, or if i should put a r32 box in ( as in a #2 box) or rebuild the one thats in it.

On the r31 site there is no mention at all about any gearbox change for the gts2, shorely if it had different trans gearing they would have mentioned that.

As far as I know the only difference between the R31 boxes was vs the VL box where one had dual synchros and one had single. This won't be affected by engine power though, moreso your gear changes and clutch work.

I do have an R32 box here, which, if you get your old box out you can bring it over and compare it with. Housings on alot of Japanese gearboxes are interchangeable so it's not impossible for you to have the housing (and therefore the gearbox number) from another gearbox. Unless you want to buy second hand the easiest way out of it will be to just get your original box reco'd. It usually only takes 2-3 days depending who you get it done with.

GTS2's definately had a different cam, as did GTS1's. Both got stainless steel extractors, and each had a unique set of mags. The ecu's in both cars were standard, but the GTS2's received a piggyback arrangement, I have heard it was due to Bosch not warranting (or more probably, allowing..) a modified ecu.

eightsixboy - For what its worth, I have an R32 RB20DET silvertop RP71C #2 gearbox in my series 3 R31, fitted up fine. I can't comment on any ratio changes etc as the car hasn't been driven yet (undergoing turbo conversion at the same time). I'd be looking for a low-km cheap R32 gearbox as a replacement personally. They will amost certainly be lower km and fresher than an R31 gearbox (unless rebuilt) and possibly have better synchro's, I haven't found information to confirm/deny that, as apparrently some late S3's got the later gearbox (september 89 on, possibly?). I have also heard that apparrently the ratios are slightly different, from what I remember 5th isn't quite as low, slightly more revs for the same speed. I've also heard that the R32 gearboxes have extra webbing over the earlier boxes. My RP71C #2 definately has it, not sure if your box will or won't.

My 2 cents..
