Guys... I dont even know where to begin with my car. The last year I have poured more money into my Porsche then the last 3 cars combined. I've only driven it for 5 months.

Just recently due to whatever reason, the timing belt slipped and now for the second time in 8 months I'm replacing valves. This time however I've been thinking... a few things up my sleeve and I would like your opinion.

1. Put it back together and finish doing what I was going to do to it. (install intercooler and other little things.)

If I do this, I plan on driving it to Indy this July(17-21) for a car convention. Which is a whole 'nother chapter.

Anyways, I was also thinking of doing something more radical... Taking it home from the shop and pulling the motor. I would then like to add a stroker kit, make it a 2.2L if possible. Then get some different pistons with a little lower compression and if possible, make it so they are grooved for valves(so if I break the timing belt AGAIN, there wont be any more damage, if this is even possible?)

Basically I want to know what I should do, I have a perfectly good running Chrysler New Yorker to putt around for however long it takes me to complete this more radical option. Would making it a 2.2 and custom pistons be worth the money, and what about would it cost? I know there are a bunch of very knowledgable guys on this forum. I don't know much about stroker kits, custom pistons and the cost of that sort of thing.

Any comments? Flames? Suggestions?? Please express them. I'm open to ideas as the mechanic can't get to my car for another 2 weeks...

Thanks
Jason

I take it, its a 924. I thought that if the timing belt slips on the 924 the valves are safe? for me that was the case

It sounds like you're looking for a non-standard, long-throw crank, shortened, possibly custom-made con-rods, custom pistons; that lot's going to make what you've already spent on your car look like peanuts!

Firstly I would find out why your belt slipped... No point in pouring more money if it's going to happen again...
Was it tensioned properly and all the head measuments within spec??
As for stroker, well it would be nice but with the intercooler and extra boost you'd be running a gearbox change is probably in order too.
If I were in your position I'd look at remodeling the front of the car to fit a nice three inch thick intercooler with a modified intake plenum like on the gtr.

For a fraction of the cost you could drop in a V8 and have reliable power.

Who did the head work and timing belt install?

It was a local non-porsche specific shop. That was last fall. I'm not sure why the belt slipped. I plan on having everything inspected upon the removal. But my idea was if it needed more than valves and general things, I would park it for a while until I could afford the stroking.

Anyone know an actual dollar cost of what parts would be practical, etc? I'm not looking for comparisons.. I want $$ amounts. I could have a v8 put in there, but that wouldn't be as unique as a 2.2L stroked/cammed/intercooled 931.

Also I am not worried about the gearbox upgrade. I'm just looking for the dollar amount on stroking this engine.

Ok...so the car was put in storage after the work was done, and now you have suffered another t-belt failure? How many miles have elapsed since the work was done? If the t-belt wasn`t tensioned properly, this could be (and probably is) the reason for the failure. A new properly tensioned belt will NOT slip teeth. No matter how hard you drive it. Somone owes you an explanation.

I probably have less than 1000 miles on the timing belt. Is there anyway to tell if it was improperly tensioned?

Even if so, the mechanic thats working on my car now, already took the belt off. So I dont know if I would probably be out of luck.

Most shops carry a 6mo- 1 year guaranty on their labor.

IMO, there is no way that your t-belt should have slipped if it was done correctly. Is the shop you have it at now, the same shop that did the work for you? Don`t roll over and lay on your back, and let yourself be taken. A reputable shop, will stand behind their work. There is no way, that you should be responsible for the cost to repair (once again) your car.

Have your reciepts ready, and stand your ground!

I'd definitely v8 it. Cheaper and more reliable, it's what I'd do to my toofah if I had the money.
