I'm using a local kit for SR20 to z33 in Australia by Insane Drifters. They're on fb.
https://facebook.com/InsaneDrifters/
Paid AUD $2350.00 including shipping.
It came with:
- Adapter plate
- Bellhousing machining
- Test fit to ensure everything fit without further modification (no chassis mods)
- Shifter w/ Reverse Lockout
- Gearbox crossmember adapter plates (suit s15 gearbox crossmember and factory mount)
- All required bolts/nuts/washers
- Braided clutch line to suit RHD s13 master to z33 slave
- Single piece tailshaft to suit abs housing
I haven't fit it to the car yet, but he uses the same setup in his ADGP s13 and his old man's daily s15. Looks the goods, comes out in factory location with no need to modify anything.
I believe he would be willing to sell components separately, I just couldn't say no to having it test fit before I coughed up dough.
Edit: I'm using the factory z33 throwout fork and pivot with a Nismo Super coppermix twin plate. I've been told that it will work - another customer has used it before I think.
