Is the 924 Turbo a maintenance headache?

Yep it sure did, and it was a prototype 16v DOHC 2.5L turbocharged version of the 944. Raced in 1981 at LeMans.
I would hold out for the later 81-82 year variants as well. Those 2.0L engines are tough but I would speculate that with the iron block and Aluminum head that a steel head gasket would be ideal. That is what the MKIII Supra boys have to do. Also the clyinder spacing is minute in between bores. The 931's used a 911 Turbo wastegate so those parts can get prciey, and the turbo uses a internal pop-off valve. Fun cars my friend has two 81's, one of which is going under some serious mods.

I should take pics of my 931 engine. Oh, I have taken pics of it, just not when I installed it in the engine compartment : 
It sure has bigger huffer than the mighty gtr
The amount of power remains to be seen (after completion of stand-alone ems)
Actually modifying the 2.0 is very cheap if you know what to do and stock crank+rods (not to talk about the block, it's made for a tank I presume) are very strong.

My 82 924 went over 300k before finally spinning a rod bearing. (sold it to a friend just before this happened). When we rebuilt the motor, the cylinder bores showed no wear. I mean absolutely no wear. The pistons had so little wear that I still dont think the machine shop believes us when we told him it had 300k+ on it. All he had to do is very lightly kiss the cylinders with a hone to break the glaze.
That was about 5 years ago. My friend just recently sold the car and has but put another 100k+ on it while in his possesion. I had converted it to side draft webers when I owned it and it still has that setup.
