Apologizes for some mistaken information I provided earlier. Looks like you are right with F40 for 3.2JTS. I based my statement on something I found on forum some time ago, or maybe I didn't remembered correctly all gearbox assignments? Now I've checked user manual for oil QTY, and 2.8L is used for 2.4JTDM (which I know for sure is F40) and 3.2JTS, so it must be also F40.
M32 (2.3L oil) then is used for 2.2jts,1.9jts,1.9jtdm and 1.75tbi (here slightly modified version with 2.0L oil, but for sure it is M32 - looks identical from outside as one from my former 1.9JTDM)
for completeness on gearbox types as far as I read
2.0JTDMs depends on year/power had 170HP: F40 or C635 , and 136HP version M32(at least some said so on forum) or C635
1.8MPI has some other gearbox (I think 5 speed)
OK, so gearbox should not be any problem for adding turbo, but to me 3.2JTS engine seems delicate, and if so that may be main stopper. Ive read good a few posts/cases on total engine failures I mentioned earlier. Also, when I browsed adverts for pertrol 159 last year, there were always 2-3 top-spec 3.2JTS on sale with engine dead (rather for spares), what was never the case for any other engine type.
Some another indirect confirmation of for what I'm saying is that it is nearly not possible to buy used 3.2JTS engine in Poland, and even if one is found, it cost order of EUR3000, where e.g. used 1.9JTDM (or any other maybe except 2.4) can be bought for EUR350 without any problem.
