Turbo motor swap/ motor and tranny swap
I have been researching a little but cannot get the answer I'm looking for.
I have an '86 rx7 NA and I would like to go turbo. Would I be able to drop a TII motor in and then rebuild the NA tranny to handle more power or should I swap both in? Thanks

Just so you know, this is the list to actually do the swap
***Keep the n/a harnesses***
S4 t2 long block
tranny (i wouldnt want to use the n/a tranny)
clutch
clutch slave
starter
driveshaft or custom shaft if keeping the crappy n/a rearend
rearend
t2 hood or front mount that ****
n332 ecu
n318 boost pressure sensor
n318 AFM
turbo fuel pump
turbo throttle cable or get tricky and make the n/a cable work
Thats the gist of it. Im always forgetting somethings.

If you plan to run the factory turbocharger then a N/A transmission of good condition will do just fine. I actually prefer to run them because of the weight difference.
Turbo II transmissions use a larger flywheel. This comes in handy because you can stick with a disk type clutch and have the holding power of a Puck type N/A clutch. This makes the clutch more forgiving for street use.
There is a difference in gearing that you may want to review as well.
