944 AC
I am actually outside today (60*)
Pulled out the 944 AC comp from the scrap pile....
Not only will it be too close to the engine set back plate on the passenger side, but there is a friggin 8-groove pulley on it (85.5 anyways). The GM AC drive is 4-groove on the crank pulley. Also I think Greg's right that the GM compressor would be an upgrade and would flow more and cool better....
I also did check and the 944 compressor would fit without hitting the passenger frame rail if a custom bracket were made and incorporated the 944 heim link tensioner thingy.....FYI

the 85.5 and later ac should have a 6-rib pulley on it, if it has an 8-rib i will take it off your hands.
82-85 had a 5-rib.
regardless though you can swap pulleys on ac compressors.

Thanks for checking on the compressor.
I just looked at mine at I was removing the brake booster and counted the ribs and looked at my new motor and came to the same conclusion. Looks like new lines are in order. I need to get all that lined up before the motor goes in.

I have this swap done, it is not too bad of a drive, the problem I have is that I still am running a n/a trans.
I am currently trying to find a second gen to upgrade my 1/1985 from that the LS1 sits in, so I have a better suspension under it and I also am hunting down a turbo lsd tans to spread out the gears.
It is a sweet car though. No big complants,

should be the same rpms you see currently..in terms of rotational speed the trans doesnt care if its an M44 2.5L or an LS9 SC'd 6.2, a revolution is a revolution

I am not sure what rpms you sit at, my tach is not hooked up yet.
I know the turbo trans has better gearing so you sit lower at highway speeds.
if you swap a ealry fifth gear from an n/a trans into the turbo trans you increase your top from 150mph (stock turbo trans) to 180mph(early 5th)
making the highway rpm alot better.
