Hey guys Later next year I will be doing a gt2 conversion on my st162. Now is my current box of my 3sge suitable for a mildy modified 3sgte ?
Possibly. It's hard to say. Depends on how the transmission was maintained, etc. Some people have had it last for a while, others it exploded on them when they hit boost.
It will work just fine, only the first boxes (1986) won't fit due to having the starter at the wrong side.
early ones have them where the downpipe sits, that's why they don't fit . Later models have it over the gearbox.
