I"m interested too but you are not going to hear anything exiting, the 924 can never become a 'fast' with the stock engine.

I just know the stock (us/can) 78 engine is 110 hp, I guess you could get 125 hp with the european pistons and other mods i'm guessing most horsepower would be 135-140 hp ..... but i'm guessing that would need alot of money to waste.

If I could afford it I would get a 928 for a fast front engine porsche....

I know that doesn't answer your question sorry.

the best way to make to a 924 faster, is to lighten it and upgrade the suspension, and ofcourse improve the nut behind the wheel..

You can eventually get over 175hp from a 2.0L NA but the block will be the only thing original to the car.

Two things are needed...

Money

and

um did I mention money?

About 140hp. or about the same performance figures as a early 944. For the money you will spend buy a 944. By the way you will not be happy with the sound or the running of the car. With carbs, cam, dual exhausts, suspension, MSD, Fuchs, larger front and rear bars etc, etc it is still a 924. We on this site fix them as a hobby, therapy, time and money waster, want to get away from the wife, we like punishment or some of us are just stupid. I am number one on the list in case some of you get mad at me.
I have enjoyed every minute of trying to make it better. Did I succeed? Maybe. How much money did I put in? A bunch.

Put the car in good shape and have fun with it. Want a faster car buy a 944 turbo and you will SAVE a lot of money trying to make a 24 a runner.

I think Vince and others are spot on there, mate.

You can make them develop reasonable horsepower, just like any other car. But why would you bother when you can get a 924 Turbo or 944 or even a 944 Turbo for less money?!

well, I think it's because those motors are nowhere NEAR as reliable as the N/A 2.0.

Anybody want to dispute this? MAYBE the 931- I don't know much about her. Forced induction is not the only way to achieve power.

The 944 2.5 litre is not bulletproof- and I just can't stand that balance shaft idea- OR the possibility of interference, for that matter.

Info from this board has taught me that the HEAD DESIGN is the weak link in our 2.0. If we can find a way around that- such as Indi9xxx had touted he had, in fact, done so. ...allegedly.

aahhh damnit.

Mild supercharging shouldn't be too hard, I was very close to doing that, but I got a 931 for cheap and gave up on it.

I think for some of us it is the thrill of the chase. I for one, will never go out and buy a 951. I don't like the cars well enough to drop 10K on one. I do however enjoy building things. If I can build something I get a sense of satisfaction everytime I fire it up.

I will be getting a 931, maybe 2, but I have some goals to achieve with the NA's first. There are at least 16 factory cars out there that manage good amounts of power without forced induction and I intend on building a couple more. Then I will move on to the turbos.

Yeah, you're right My924gtc. I didn't mean to suggest it's pointless to upgrade the 924. Sure you can, if you want!

I just felt the tone of of crackmonkey's original post suggested he was just looking for high horsepower from his early 924 NA, which is sort of a pointless exercise given that a later Turbo or 924S is already a much higher performance vehicle (with higher performance parts like head, exhaust, suspension and brakes), and would probably be much cheaper to buy than trying to modify an early 924 NA to the same standard, y'know?

I didn't mean to be harsh on the 924 either. I'm obviously a fan! What I should have said was, spend your money on suspension first. Talk about a nice handling car.

Suspension (almost a given on any 20+ year old car)

Great thing about doing it to our cars is that it yeilds very good results with, in the scope of build costs, little investment.

Motor

You can realistically expect to meet stock 931 performance w/$3K worth of engine modification.(If you can do the work youself, less the machine shops bit) Bored, pistons, 931 head, Cam and Webers. Yes barely streetable, but can be done. And this gives you a newer than new motor.

Restoration

So if the object is to have a nice 924, fully restored, with the performance of a 931 or better, and do it for less than 6K, (which is at least what any 931 owner would want for a comparable turbo car), I see nothing to say that one way is better than the other.

First of all I apoligize for my bad typing and spelling.

I am going to do suspension. Im planing on putting on a sway bar that my friend is giving me off his parts car. Upgrading the front springs to 250lb springs. Then I was going to upgrade the torsion bars.

Eventualy I want to replace the cis with an efi system. To maybe get some more gas milage on the fact that its not constatly spraying feul into the intake. So that I will be able to find those parts in the future. Yes I also would not mind some more hp. Finaly one of the bigest reasons is that I love doing stuff like that, but unfortunatly I don't have any expierance doing it as this is the first car I have ever done much work on.
