 porsche 924 turbo (931) questions... possible track car?« »

This was posted on Audiworld by my brother but I have alot more faith in the car lounge so I am posting it here for his sanity. Any help you guys/ girls can give is greatly appreciated.

As posted by my brother ...

here's the deal,,, I want a older dedicated track car, <s4 content> the S4 just costs to much to be anything other than a once and a while excursion </s4 content> So, I was going to to just go with another mk2 GTi or scirroco, since I know them best, but while out and about today, I can across this... it is a 1980 Porsche 924 Turbo (931?) 57,000 on the clock... body is in good shape sans the paint peel on the hood, all lines are evenly spaced and don't appear to have been replaced. no dents of dings anywhere

First off: Is there anyone who knows anything about these, do they make good cars for the track? Can you point me in the right direction for valuable information regarding the 924 turbo and it's potential as a track car,,, or is it a waste of money.

Second: if it is not a good track car, at the small sum of money it will cost to get it (see below), is it worth buying for fun?

Normally I wouldn't have even though of getting into a make and model I know nothing about, but the yard gave me a number I prob. can't refuse ($500, drive it away, papers and all...)

thanks in advance....

Does it run?

For $500, why not?

memories. my friend bought a 924 for $100. i would drive for 1 block and just stop altogether. we had fun with it, and learned alot on it.

if it runs, go for it. you will be able to make a profit right away if you decide to sell it.

IIRC 924s handle very well in stock form.

The turbocharger can be busted because of overheating, have it checked out. This is because it sits too close to the exhaust manifold.

The rod bearings may need to be replaced. You can spun it very easily.

If you want, you can fabricate a intercooler for it. You can use an intercooler from some another cars and fabricate the pipes and such. That will increase the power and extend the life of the turbocharger.

You can also get a set of forged JE pistons with higher compression rate from EBS Racing.

While you have the engine out, you can replace the spring in the wastegate to the one used by the 930 which will increase the boost. While you have the engine out for the aforemention stuffs, replace the four engine mounts if they are busted.

As with other P-cars, it handles great out of the box It should be good for track use, but make sure you don't overheat and over boost the turbo. There is no boost guage stock so you might want to add one. If you just want a "cheap" track car you may also want to look at the regular 924 and 924S (which has the 2.5L engine and some other running gears on the 944) since you don't have to worry about the turbo.

931 is pretty rare! However, if you want a better car out of the box, get a 951 There! I have said it

At $500 a 931 is damn good deal. The 931 is a well-balanced handler, and imho makes a much better platform for a track car than a GTI or Scirocco. Assuming like condition, I would say the 931 would be a little more expensive to maintain by virtue of the turbo and associated wear and tear. Obin probably knows a little bit better the performance limits of the 931, but if I remember from back in the day, the 931s were capable of being modified to about 200hp relatively inexpensively while still maintaining reliability. Another benefit is the interchange with other Porsches, mostly the transaxle cars, but also with some of the aircooled stuff. If you look around for the right handmedowns, for not much money you can have a partsbin special that'll dominate every other car out there on the track.

If you're willing to have a 931 track car you must have a lot of courage. They are the most expensive car out of 924/944/968 series to maintain. Good luck finding a lot of parts too.
Rare porsche with uknown maintanance history is the worst porsche you can buy.
Unless you brother is a VERY skillfull mechanic or has a solid parts source i say Run....

and i do know a thing or two about front end porsches, i have 84 944 and 88 951S.

p.s. $ 500 is a good deal though

I still do not understand why people freak out about maintenance on the 924 and early 944 series. The ECU is reallly the only high - tech piece. I mean, people act like they are so intricate, you have to have a master's degree in engineering and special accredidation from the Porsche factory to change the oil. Come on folks!! In-line 4 cylinder, single overhead cam (on most), torsion bar rear suspension, do these sound like the workings of an exotic? Tell y9ou what, the reason I love this series is also the reason I love the Z06. Basics. Light weight, high displacement, balanced chassis, traditional technology. Seriously, If I started a list of how simplistic the 944 2.5 is, you'd think I was crazy.

Now, to tune these does take patience and understanding, and yes the 924 Twould require a bit more than the 944 T due to the amount of resources available. But neither are bad, and if you didn't want to bother with the engine, take it out and transplant in a sbc. fairly straight forward, and does not upset the weight balance. Take it from me, I've also had plenty of experience with the bastard children of Porsche-VAG, along with more years behind the wheel and the wrench, than most of these people have been out of diapers.

Well....I am very comfortable with any 944 and most 924s. But I agree...the 931 is a very expensive car to own vs others in the series.

I would pass on that car and get a 924s or a 944. Parts are readily available and upgrades are all over the place.

Check Ebay.....lots of 944s for sale.

Okay, I will agree on the expense part, due to rarity, and aftermarket support. I just get tired of people talking about how hard these are to maintain. The layout is such a dream. I miss driving mine, but I just gave it to my dad for a fun car as he was having trouble keeping the twin carbs on his datsun 1600 tuned. Well, at least I get to drive it when I visit the folks!

Back to the topic though, If you wanted to put some work in, the car looks pretty complete. Therefore, you could look for a donor 968, transplant the engine and drivetrain over, and have one heckuva track car. Remember, the 944S' routinely spank the 944 N/A's (along with other models) on the track. However, the widebody on the 944 is pure sex in my book!

I believe the main concern was not necessarily how much work is involved or the maintenance, but more the cost and availability of replacement parts. Both my brother and myself are mechanically inclined, and we have experience in both older vw's as well as turbo cars.
