Could i use a N/A manual box for auto/ manual conversion for a Twin Turbo ?

 

both are Jspec,

yep but needs some tooling / modifying to fit and you'll need a new TT clutch as the n/a one will burn out if you dont...all do-able as just had mine converted at Zen

the bell housing needs swaping over if i recall.

Not really, box isn't as strong and also the bell housing is smaller so will need the starter spacing out...

The box has never been a problem on any we have fitted and I don't think there have been any problems with any other na box's on TT's. You just grind out some of the inside of the bellhousing and away you go!

Starter will still need spacing out though unless you use a NA flywheel....

Thank-you for your replies very helpful

i thought the internals are the same :p just the bellhousing thats slightly differant

There were unconfirmed reports that some of the internals are uprated but never heard of anyone having trouble with the conversion, so whatever they uprated didn't make much difference :hyper:

The only differance is bell housing and speed sensor.

the pinnion on the na is smaller and the internal drive

gear is larger, You will have to buy a new n/a speed sensor

pinnion gear and fit it to your TT sensor.
