i think the nismo box is only rated at 400ps? Alternativley you could go for a ppg gear set from australia but i think thats only for the s14 5 speed box.

Z32 box for reliability. Mazworks in the US makes a fitting kit.
Or you can go the expensive route with dogbox :) Ikeya Formula makes a dogbox which you can use their seq shifter with :)

Has anyone on here done either of these conversions
Will the z32 box take the power

Looks like the best thing to do for now it to just get another s15 box
until funds and time allow a upgrade:annoyed:

Has anyone got one for sale
How much would you expect to pay for one

damn! Just out of curiosity what kind of power are you pushing out to destroy gears like that?

You can check out the ORC gear set as I heard they're strong, my friend is running a 500hp S15 and his uprated standard 6 speed gearbox just break also

I have a 6 speed thats stuck in 6th, if thats any good to you.
How much are you looking for the box, I might be able to make 1 good box out of the two

might as well up the spec... if you gonna rebuilt it its judt gonna happen again.
Yes I might get a z 32 conversion although the z33 6 speed is is ment to be stronger but a lot more expensive

You can check out the ORC gear set as I heard they're strong, my friend is running a 500hp S15 and his uprated standard 6 speed gearbox just break also
The ORC gear sets only fit the 5 speed box and I know a few lads
that have broke them

I dont know what to do yet ,I think I will rebuild the box that I have to standard spec and keep it as a spare and then either build a super strong
s 15 box or just go for a z32 5 speed or Z33 conversion but with these conversions I think the gearing is a little longer so its hard to know

Let me know what you think
