I am by no means a pro at this but I will tell you to do some searching which is what I have been spending a lot of time doing. a Integral cam seems to help. From what I am understanding we really need to get more air in, ie.. cam and serious head work, compression will help a ton also. Exhaust, there is headers and cat replacement flowtubes available, but if you can't get the air in it won't help.

Best way to get real improvement is to make sure the car is in perfect tune and start removing weight.

I am not trying to sell this as God's honest truth but more as what I have read and been told.

Just as a side note I just spent 600.00 on my exhaust but I went with all stock replacement parts rather than the header and flowtube which would have only cost 100.00 more.

Definitely do a ton of searching and you can extract a lot of info.

Later,
Chad P.

Check on a 5 grear trany, it might be cheaper than rebeilding the old one and you'll get better performance.
For upgrade, I suggest you start with a good tune-up, timming and get a K&N air filter, check ebay for a audi 5000 throttle body and a performance header.
With that you should pass from 9.9 sec to 8.0-8.5 sec on 0 to 100 Km/h.

Have fun.

what's your budget? plans for the future?
Get into the car and look at all the aspects of it, mechanical, electrical and appearance, wear&tear...
You can also gain performance and reliability by re wiring the electrics, 20+ years = corrosion.
So if you haven't done so already get a Hayne's manual or factory workshop manual and suss the car out fully.
As for performance there are many options, rebuilding stock engine, increasing bore, stroking the crank, forced induction (turbo/supercharging) headers, larger free flowing exhaust, electric water pumps, smaller pulley, cams, lightened valve train, porting the ehad, bigger valves, supension... the list goes on... including engine transplants...
I think one of the first things to do is get a leakdown test done, this will tell you the life of your engine, if you need to rebuild it or not. As for upgrades what are your skills , and timeline, is it your daily driver or hobby?

well im 19yrs old and work in a factory lol so i have some money nothin crazy. its is my daily driver at the moment but im about to get a winter car. so i wanna work on it this winter. like i said the interior is great on it the body color was orginaly silver but somebody it looks to me like spray paint black. the guy that i bought it from said that it was a custom paint job called california blackout haha he also said there was no bondo but there is basically on both front fenders the lower part is bondo. but thats alright. as far as engine i would like to either turbo it or supercharge. havent looked for a supercharger yet searched for a turbo and it seems to be hard to find.

before you start anything you must decide what exactly do you want to upgrade for...if you wanna just bolt on stuff...then you can swap wheels...tyres...brakes even....but if you want to upgrade for more power...then you've gotta do some brain activities.

Prior to looking for a supercharger you must first learn how everything works and how to make the car work with a supercharger...and unless you are some sort of genious you must first read as much of this forum as you can and ask all sorts of silly(read stupid) questions

firstly you should get a comparison between your car and other 924s around....maby drive one or so..or at least compare things like engine noise...performances...oil consumption...starting issues...control fuel pressure....and all sorts of data. All this to determine if your car is realy runing as a porsche or its an audi runner. For example I never knew that my NA engine was so terrible until i got to compare my car to others. Then i knew i have a shit load of stuff to fix for the car to run AT FACTORY SPECS...all this prior to thinking of upgradeing it.

After you have learned all thats possible about that NA engine and you can get your girlfriend to pick a part of the car and you can easly explain how it works and how it integrates in the car...well then you can start thinking about upgradeing for more power...but in the meantime you should also upgrade for safety...so....good luck !

oh...i forgot about money....yea...you will need well...all..the money

Look into Megasquirt. You can get rid of the mechanical fuel injection and convert it to electronic fuel injection with the Megasquirt. That'll give you full control of your fuel delivery, and remove the huge restriction the CIS system puts in your intake. That alone will do wonders for getting more air into the engine. If you are feeling really adventurous, you can ditch the distributor and go with a distributorless ignition system, using the Megasquirt as well. This will help save you some hassle with having to do tune-ups all the time. It'll also give you full control of the spark curve so you can take maximum advantage of any upgrades you add to the engine. MegaSquirt is only $200 or so..

Mate, you wont want to hear this any more than I did at 19. But from experience, here goes.

Spend a little money and time on getting your 924 to run well as Porsche made it. Ensure it is up to scratch safety and maintenance wise.

Spend your time working and then enjoy driving it with your girlfriends company. Spend some spare time reading and learn about the car itself and the possible benefits and drawbacks of various modifications.

Save your money for a deposit on a HOUSE. Put all your spare money into the mortgage. After years of working you will still have something to show for it.

When you own a large portion of your house and another reliable daily driver , and have money to waste then maybe think about putting on a blower or turbo or buy a 928 or a cheap Boxer by then. You will NEVER get back the money you put into this car above minimal repairs. You will have a big problem getting insurance and WHEN you stack it will most likely only have a big debt.

I will give this advice to my kid since I now realize that I shoud have payed more attention to this same advice from my mum.

Anyway, welcome here. Good luck whatever you do.

Standard grade plugs and good quality carbon cored (suppression) leads from your local auto parts shop will be fine.

Megasquirt is not HARD TO USE, and neither is the stock CIS. BUT, MS is much harder to build and set up than it is to tune what you have. While a kit of electronic parts can be bought for only $200 it will cost you over $1000 to build and get running to a good standard. As well as probably 100 hours of reading and study.

It is not a cheap or easy way to gain a few horsepower or a bit more economy or driveability. The search feature at the top of the page will give you much to read about the subject.

A BAR is a place licensed to sell alcohol (to over 21 yo. in the US, I believe)

Also refers to 1 atmosphere of pressure, or 14.7 PSI.
No offense, but if you have to ask you have a lot to yet read about forced induction.

Honestly, the best thing to do is the tune up and get your car running and looking nice. Enjoy driving it while you READ and PLAN any modifications.
