Well after a year of messing with the old car, my parents garage finally got a little emptier (to provide a comfortable stay for my dads new 968). The 931 went to a gentleman who restores older/cool c ...

14 yrs is a long time to sit.
Would they have had better quality fuel back then for you to have just a minor problem?

Well, that wasn't the only problem with the car, but it was the only probl ...

For the most part it's prob fine. The piston is likely stuck. My car sat for 14 years.

Well, I went to the bottom of the internet to find out very few things. It seems that almost no other car used a threaded injector. Mercedes, VW, Saab etc. injectors are the push in type that hold wi ...

Are there fuel injectors from other cars I can use on the 924 turbo? On my shelf at this time are:
Merc 560SEL
VW Jetta 16V (1988)
Audi Coupe (1982)

I'm not sure there are huge differences. The ...

If I bring up the revs in neutral I can hear the turbo spool up all the way to 7 psi. Is that normal?

For once it would be nice to be hit by an idea instead ...

I just picked up a Goetze headgasket instead of the Victor Reinz brand. It appears to be thicker and beefier. But I don't know how much it ...

Well I put most of the engine back together. Flattops and all. Then I simply hooked up the starter and sort of bench tested the compression. Even with the rings not entirely seated yet, I already got ...

Gegge,

Bore 87
Stroke 84.4
Head Gasket Bore 87.8
Deck clearance 5.4
Head Gasket thickness 1.7
Head Chamber Volume 22.5ccs

I checked ...

I'm running megajolt ignition which is like megasquirt, except it only does the ignition part. Even running the timing to near 0 advance under load, it still pings. The fuel system was tested and work ...

I rebuild the engine with mahle flattops as my original pistons had broken ringlands. I had the block bored to 87mm and the connecting rod bushings put in to run the 22mm wrist pin. I didn't really do ...

I think I got it!
I had a multimeter hooked up across the battery terminals and as soon as I put the positive cable back to the battery, the voltage dropped from 12.6 to 12.04. I then pulled each rel ...

Yeah the gas mileage seems to have gotten a lot better. Now it's on to other things like a new brake master, wiper motor, starter and who knows what else. One of these days the car may actually functi ...

I just switched out fuel pumps to a proper 924 turbo pump. Car runs miles better and at idle the air sensor plate is closed a lot more than it was before. No more hesitation and the manifold doesn't g ...

Thanks for the replies. I just ordered my CIS-tester. The fuel pressure gauge I have apparently doesn't work with this system and I don't want to burn the car to the ground ... yet.

I only drove th ...
