I am currently in the process of converting from RB30 to turbo setup. I did do a search and struggled finding the info. I know a few things that vary between the two but thought this thread could help me and others who are doing the same conversion or looking at doing it.
My first questions would be when doing the gearbox swap from standard RB30 5 speed to the MX7. What is compatible?
I have noticed the sandwhich plate is different between RB30 and RB30t.
The clutch splines are the same but I dont think the standard clutch will take the boost. Does the RB30 have a smaller clutch compard to the RB30t?
Are the RB30 flywheels different to RB30t?
Are the RB30 starter motors different to RB30t?
My other questions are about the fuel tank. I am assuming the turbo fuel pumps are higher output. Is there a difference in the fuel tank itself? Has the turbo got an in built surge pot or baffled tank or are they the same as the RB30 tanks.
Any info would be helpful and feel free to add any sort of info if you were to carry out this conversion eg engine A6 to A8, wiring harnesses, tailshafts etc etc.

the n/a or mf5 gearbox has a 9/5inch flywheel . where the turbo/mx7 has a 10inch flywheel.so you will need to use turbo gearbox/turbo fly wheel together and clutch to.all the other manual bits. tailshaft.gearbox mount. are same from na to turbo
fuel tank and fuel pumps are the same. so dont get sucked in someone trying to sell you a vl turbo fuel pump

Gear box, flywheel, clutch, tailshaft yoke, starter motor and speedo cable are different between MF5 (N/A manual) and MX7 (turbo manual). Fuel pumps and tanks are identical.

No worries. That helps alot. Are there any other bits and pieces I might need to know about?

might be worth while when your changing over the bits, to change the spigot bush

Yeah thats on the cards. Thanks.
I have two inlet manifolds. N/A and turbo. I have heard some people using the N/A lower half of the inlet manifold on turbo applications. Is there a benefit to this and what is it or is it better to just use the complete turbo inlet manifold. I can visably see the runner lengths are different which I believe can effect torque so is it an advantage or disadvantage to use this or does it depend on the application.
