    Hornung's 1987 Porsche 944 Turbo

    So this thread will log the inevitable repairs that will need to take place with a car of this age.

    Some details:

    Alpine white 944 Turbo, internally known as the 951. 107,000 miles on the odometer with an impressive history and ownership. She is a former track slut, now daily driver. She makes 250 wheel horsepower and 260 wheel torque on aftermarket tuning and 15psi of boost. (I've played with the boost level and it definitely makes a difference!!)

    Things needed are:

    • Compression and Leakdown test
    • Engine mounts
    • Timing belt
    • Find the oil leak - I suspect the Air Oil Separator or AOS (Common failure)
    • Fix the rear hatch glass - frame needs to be stripped, cleaned and reglued
    • Adjust rear hatch pins - Unending rattle when I hit a bump or imperfection in the road.
    • Need a good tune up with distributor, rotor, plugs, wires and an oil change
    • Silicone J boot (Runs from the MAF to the Turbo) wears just like an M54 Intake boot
    • New brake pads
    • Nissan Quest Alternator Mod replaces the archaic charging system from the 80s
    • Upgraded 7" headlights. Output is horrible coming from ALs with ZKW lenses and the trifecta mod

    I'm confident I can do all the work myself and I'm looking forward to Sundays when I can get under the car and wrench.

    Now some pictures

    More to come. Hopefully the parts I ordered from Pelican fix my current Oil consumption issue (About 1qt/2000mi).

    Cheers!!

    Very nice, looks like a solid car! Looking forward to this build. Shouldn't you have done a compression test before you bought the car?

    I had it inspected before I bought it. The oil consumption wasn't brought up. But there are things you have to be savvy about with these cars. Lots of simple issues that might show up as a major repair level symptom. I.E. milk shake in the filler cap. I'm not burning coolant (white smoke), so its not a head gasket. But I am burning oil so it could be blow-by. If the crankcase is pressurized, then that will allow oil to be burned off as its forced passed the piston rings. The car isn't low on power, so I think it's just a bit of blow-by. Could be fixed by rebuilding the o-rings on the AOS or I could run a catch can and remove the vacuum from the crankcase. Stay tuned!!

    Yes hopefully some vids shortly. She's a screamer when the boost is turned up past 15psi. It's rumored she'll hold 23 before overboost protection is engaged. Not trying to blow up the car.

    Aside from the snakes of vacuum lines under the hood, this engine is surprisingly easy to work on. Lots of removal steps before you can actually get to the part you're trying to fix.
