Up for sale is my OS GIKEN OS88 sequential gearbox option 2.

It is brand new and still on the pallet and comes with crossmember to suit as well as direct shift kit.

Comes as a combo with NPC twin plate clutch custom built with billet flywheel.

The OS Giken OS-88 gearbox is a sequential 6-speed gearbox designed to suit the BNR32 and BCNR33 GT-R.

It can also be used in the BNR34 but will require an R33 transfer case and front prop shaft.

It bolts up to the Nissan transfer case and has a bellhousing to suit any RB engine.

It also comes complete with shifter, digital shift indicator and pull-up reverse lock-out sleeve.

OS Giken designed this sequential gearbox to handle 1500hp, while retaining quiet helical-cut gears.

To do this the gear axis has been increased to 88mm, while most internal parts are forged.

The dog-engagement of the gears allows extremely fast shifting, but does require regular inspection to ensure trouble-free operation.

This gearbox comes with the following gear ratios:

1st 2.609

2nd 1.934

3rd 1.521

4th 1.210

5th 1.000

6th 0.852

Please contact us if you would like to choose one of the following "option" ratio sets ($900 extra):

Option 1: 2.609, 1.934, 1.521, 1.210, 1.000, 0.785

Option 2: 2.890, 1.981, 1.468, 1.174, 1.000, 0.757

Option 3: 2.516, 1.865, 1.468, 1.174, 1.000, 0.822

$20 500 for everything

This thread is a whole year old so probably sold by now.

But rated at 1500HP, i forget what torque they are rated to but i an putting one behind my 3.0 which has a heap of torque which is what it was built for

Try Import Monster or Otomoto depending on where you are located

    • Im not entirely sure exactly what or where its leaking from, he started to pull the boots to swap to my new tie rods + ends and it just vomited fluid, so he closed em up up, swapped the rod ends to the old rods and let me know so I can figure a solution out, im guessing its all origional as as I passed 103k miles earlier this year im sure its just in need of a full overhual/rebuild anyways.    If i could just yank it off and be good it wouldn't be an issue to ship it out and wait for the turnaround but the guy I work with doesnt really have space to keep my car for a week or two at a time, would rather drop it off and have a replacement ready to drop in
    • What do you mean by "seals"? Internal hydraulic seals (ie, is it leaking PS fluid?) or the rack boots that close the rack onto the tie-rods? Because the former is a rebuild, and the latter is trivial that you or any nearby mechanic could do. Dunno about the cowl. Just buy what you think is required and get anything else you find/break afterwards. Wing? Dunno. Don't like R33s enough to pay attention to them. Mirror glass is just glass (on the surface that you want to polish). Go for it.
    • Hello! Long time lurker, been using the forums to address concerns and questions from afar for a while but I've struggled to find some answers so I guess its about time I made an account and formally asked some more knowledgeable people, since finding local skyline owners is hard (and shops that are knowledgeable or trustworthy to work on 'rare' cars are non existent out where im at, as skylines are quite uncommon to find in the wild around here). So the main 3 questions I have, 1: Steering rack has blown seals, well.. they kind of hold but they are not sealed properly anymore and as my R33 is my DD, i cant exactly rip the rack out and send it off or attempt to fix myself. As most refurb ones are around $1,100 or more shipped, and I have other things I need to work on around the car, I was seeking clarification on whether an S15 rack will more or less bolt right in, and whether a common mechanic could do any other required work to get it to fit. I ask, as I've found a supplier than can sell a manufactured as oem one for around 400, if not I'll likely order a used one from Jacks JDM, and take a risk on the seals there. The second question i have is that im replacing the front wiper cowl and have planned to buy 4 new clips and a new center clip but wasnt sure if there were any other clips that would also need to get replaced while I was at it. Given im sure any that are there now will simply break when I remove the old cowl... Last thing would be a fairly straight forward question, i think. If I manage (strong if, finding one has proven to be a pain) to find a R33 GTR spoiler/wing will it require much modification to bolt to a S2 R33 GTST? I've read the bolt patterns dont match but otherwise would bolt in, only options I have found with much luck is China stuff on ebay and carbonetics, which has a nice $650 shipping fee... so if anyone has any pointers where a US chap could locate one that would be great Random side question as well, the mirrors as I understand are mirror glass, and as im planning to polish my windows from water spots and surface scratches, i was hopeful cerium oxide would be fine for them too, as my research points to, but clarification is always nice. Any pointers would be appreciated, and while I have scoured the internet for answers if I missed a prior post somewhere that may answer these directly please point me towards it, as i must have simply missed it. I have seen a post here or there that has mentioned it, but I usually get 50-50 answers, or half answers... I dont have a lot of fab experience or mechanic experience, outside of hydraulic and pneumatic stuff I did in the military and with how hard it is to source stuff in the US, id rather not wing it and hemmoraghe money lol. Thanks guys! Sorry for the monumental first post haha
    • Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!
    • Got you mate. Check your email!
