can u run a turbo without a wastegate. and or bov

Does it matter what chassis i have for a s4 engine and manual trans? No, the chassis are the same, just make sure you keep the drivetrain consistently TII or NA. You can run different diffs with an appropriate adapting driveshaft, but everything on either end needs to be all TII or all NA.

Can u run a turbo without a wastegate and or bov? Yes, but you'll have no control over how much boost without a wastegate. It'll run the turbo at its maximum all the time and unless it's tiny you'll probably blow up the engine. A blow off valve is less critical, but generally it helps things live longer, help with response after shifts, etc. Not so necessary at low boost, much more necessary at high boost. Run both, look for other places to cheap out.

so all rx7 diffs are the same just the transmissions and driveshafts are different. right

No, EVERYTHING about the drivetrain is different, but it'll bolt to any FC chassis. What I was trying to say is that you can have a TII tranny and NA rear end, or the other way around, but you need a special driveshaft to be able to do that. But everything on either end of that shaft has to be consistently TII or NA (ie TII tranny, clutch, flywheel with NA diff and axles).

how hard is it to swap diffs.

if you have everyrthing it's just straight forward but some muscle work is involved.

Sorry for a jack But How can you tell the Difference
Between a N/A Diff and a TII diff?
This might help you out to

TII has bigger, stronger everything in the drivetrain.
