what you get an r33 gtst box and change the bellhousing with an MX7 box. wouldn't it boltup exactly the same as the MX7 and you would have to change is the speedo thingi?
The Nissan boxes don't have a bolt off bellhousing (like the supras) but instead are a one piece design where the whole front half of the case and bellhousing is the same casting. Whether this could be fitted to the MX7 I don't know.
Isn't the RB25 box pretty much bolt up anyway?
from what i've read the speedo connection needs to changed and the clutch slave cylinder where it connects up to the gearbox has a diffent mounting position.
the other one is the turbo flywheel doesn't fit, u have to use a n/a one, altho i've heard that some ppl have got it to fix with the turbo flywheel.
