Question about z33 gearbox conversion on a s15 flywheel and clutch - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hi folks , I am a lurker on here don't post much at all , just read and read.
I'm a regular on a uk based forum Driftworks but experience of this conversion is lacking in the UK , I thought it best to ask here.

I have an s14 with sr20det , I am converting to the z33 (350Z) gearbox via adapter plate and machined bellhousing , this uses the stock style s14 flywheel and clutch.

My friend also wants to replace his gearbox on his Silvia , which runs a s14 engine on a s15 flywheel and clutch (nismo flywheel and nismo super coppermix clutch) , Do we know if this will work? or do we need to use this one without a machined bellhousing , I believe the spigot bearing is in the flywheel on s15's unlike the s14 where it is in the end of the crank.

Anyone got any real experience with this please ,

Hi, we are in the process of doing this conveersion down here in NZ, we are using a conversion plate purchased from the states, we have fitted a S15 dual mass twin plate clutch/flywheel made by xtreme clutches, we are using the 350z slave cylinder with a lengthened braided line as the slave cylinder is on the LHS, also we have had the driveshaft lenghtened with a larger yoke fitted, also the gearstick is further back so this needs to be cut into the tunnel, also the crossmember needs refixing but the most work is the enlargement of the tunnel to allow the bellhousing to fit, all in all quite alot of work involved!

Z33 boxes are expensive here in aus and it seems the kits for this conversion is based in the states where I believe the z33 boxes are rather cheap. Is there anywhere that can organise a box and conversion kit and send it down to aus. If so pls inbox me I'm trying to figure out price o doing this conversion
