My mate has a VL Turbo and bought a close ratio gear box from an importer not knowing it was close ratio... As far as we have researched the only 2 close ratio gear sets are from NISMO ($2500+) and OS GEIKEN ($3500+), The gearbox is in good condition, no drive gears have noise, If you are in Brisbane and are serious about buying it we could probably arrange for you to see the geabox in action... We are going to remove it soon so if you are keen you'll have to jump in quick i guess.

Reason for sale - He has a large cam RB30ET with a highflow turbo, Paid a large sum to get his diff done previously and the car sit's too high in the revs on the high way, goes thru the gears too quickly it barely makes full boost before he has to change, It just does not suit His car.

The gearbox would be good for drifting, drag or race cars, or if your a real keen streeter... It would have stronger gears etc...

I'm pretty sure gibson motorsport used a similar setup gearbox on thier track cars.

anyway he is keen on $1800 for the gearbox, they are worth alot more then this and would not turn up often.

Have you opened the gearbox and had a look? Going by your advert one may be inclined to think it would only be nismo or os-g but it could be anything. Im looking for a gearbox, and if you can confirm exactly whats inside you may have a buyer

I'll see what i can do...

Ok pulled out and dismantled gearbox today... took a heap of photo's...

anyway measured ratio's by turning tailshaft and watching input shaft...

These are only rough guides...

1st 2.82:1

2nd 2.07:1

3rd 1.67:1

4th 1.32:1 (this is in the position of 5th gear)

5th 1:1 (this is 4th gear)

Exterior Pic 1...

Exterior Pic 2...

hookshift2.jpg

5th gear (or 4th :P)... Layshaft is clearly different from stock, notice the cone shaping is smooth before 5th...

hookshift3.jpg

Front side layshaft... Notice the gears have no machine marks down the middle of the tooth, clearly aftermartket...

and the layshaft has different machine marks on it...

hookshift4.jpg

Comparison Pic 1, The stocker is the rear one...

hookshift5.jpg

Again the front side... compare the gear sizes with the next pic...

hookshift6.jpg

Stock rb20 gearbox front side... notice the machine marks on the stock gears...

hookshift7.jpg

Rear side comparision... Stocker Is on the left... Notice the size of 5th...

hookshift8.jpg

Stock rear, notice the crappy surface on the cone before 5th on layshaft...

hookshift9.jpg

Again The rear of gearbox for sale...

hookshift10.jpg

Gearbox looks mint internally, no scoring, gouges on any gears...

There are no stamps on the gears so who could tell...

BTW Immo thats impossible, the layshaft is all one peice, you cannot chop and change gearbox's like that...

It's aftermarket anyway, they don't make aftermarket gears weaker then stock ever, so they are obvioulsy stronger... its closer ratio then stock... don't know what the gear ratio's are stock but 5th would be like 0.7:1 i guess...

    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it. 
    • Not yet quite as bad as what we've seen a Jim Berry clutch do in an R32 GTR though when it decided to cut a chassis rail in half... Still very very gnarly and a great reason to avoid.
