The Z33 trans will fit. It's not that much different to a Nissan skyline r33 gtst gearbox, which I have one in my s2k.
The nissan bell house was chopped and welded to a cnc billet plate in the shape of the font 1/2 of the s2k bell house. It was done this way because the first trial the weld between the honda s2k and nissan bellhouse broke and costed me a bomb to replace the damage bits. The shop blamed on the s2k cast material rather their welding. You will need a nissan clutch + custom flywheel to mate the f20c to the nissan clutch. If I do it all over again, I would probably use the supra 6 speed gearbox. |

If you could do it again what do you think about using the most of the s2k housing and as little of the z33 trans as possible? keep the stock flywheel/pressure plate/throw out/pivot arm etc and just change to a nissan spline disc. |

I have read mixed things about the z33 transmission so I am weary about this being a good solution.

Do you hear of them blowing them up often? Cause I havent heard of it, I know the earlier ones had a synchro issue or something along those lines but nothing major. Those guys don't have gearsets made for them, or have different transmissions swapped into them so I would assume they are pretty happy with what they have just like the supra community. |

this was one of the links I had been looking at referring to them blowing up, but I also saw quite a few saying they are quite stout. Like this one comparing it to the getrags: http://www.freshalloy.com/forums/arc.../t-168517.html |

My initial problem was with the weld between the honda and nissan bellhouses. It came apart at the drag strip after launch, 1st and 2nd gear. Fortunately the gearbox did not dig into the drag strip and flip the car otherwise I would probably not be able to type this atm. The workshop blamed that the honda bellhouse material is too "porous". To be honest I don't know if that is correct but just grateful of the big fellow up there. That's why I got the honda half of the bellhouse CNC from a billet block.

Supra gearboxes are rare and expensive over here too. However the close 6 speed ratio will have less stress on the synchro and if I used this box in the past I would not have put a set of dog gears in. The dog gears requires yearly maintenance, rebuild and oil change, for reliability. I had 2 sets fail on me in the past few years between 2 cars. |

Or would you even sell the bellhousing if your going to be doing something different? I dont want to blow up a trans every time I go out, I'll have built 8.8 or 9" under the car, its just gonna be a trans thing. I want to enjoy the car, and be able to beat the piss out of it, not fear breaking it. |
