Open the trunk of the BMW and fill it with concrete. Shouldn't need more than a couple of yards at about $80 a yard - so figure $160 tops. That should slow the 325 down far enough to allow the N/A's to take it and you'll save over $1840 in the process.

lol...that was harsh, icat. 
So you want to keep up with a 325? Not that hard. Chip/Cam+Deck to 10.5/Exhaust.
It's that easy.
Beyond that...the lightened flywheel would certainly help acceleration, but it can't be done for $1000. Not with all that other stuff anyway.
Good luck.

Suspension. Upgrade the suspension - for $1000 you can go with firmer springs, better sways, new shocks. A full coil-over conversion will run you closer to $2000, but regardless, even a mild suspension upgrade will make a world of a difference on our cars.

I do know that on the same dyno the same day my spec car came in 16 more hp than another spec car. His car was 100% stock and never opened at all.
Mine had been run hard, but I cleaned the head and rebuilt just before, Seals only no piston work, and about 20 races before did stock valve job the head. I also had a chip.
My guess were 3 hp chip, 3 hp from cleaned head, 10 hp from removed cat. Ths was based on the difference between out cars and estimates from other spec guys. The other guy was to pull the cat and re dyno to test, but I don't think he ever did that.
you can get 20 hp, but it is not easy to do. It will take money and time to work with the right shop to do it as there are few if any "20 hp" kits avaible at and price.

^^There is no way a NA will gain 10 hp from removing the cat. Unless if course it was super plugged before or something crazy like that. Now on a turbo car, that's a different story...

Just don't drive on straight roads as much!
I think NOS is the best and only way for under $1000 that you will get the results you're looking for. You should have read the board before you began finding a car to modify. You can still sell both NAs and buy a Turbo.

Ted,
That is my conjecture based on running with the 944-spec cars. We have more dyno tests between us and more time and effort spent looking for power than all of you guys. (except maybe Geo). Anyway evidence is mounting that a removing the stock existing cat on a car yields the biggest hp gain we spec guys see.
Of course without back to back dyno testing it is hard to confirm. I like I said in my original post. My motor vs anther 944 were 16 hp different same dyno a few hrs apart. My hp was withing the norm for all 8-10 944-spec dyno charts. At least within 4-5 hp. These car did not have the cat.
The car 16 hp down did have a cat. Talked with a guy who built his own car. He noted a change in butt dyno from removeing the cat. I did as well many years ago. So that why I asked of if the guy 16hp down would pull the cat and re dyno. This way we could know for sure.

I WILL LIKE TO HEAR IF IS POSSIBLE OR NOT BEAT MY BMW 323IS EUROPEAN OR EQUAL ACCELARATION AND HANDLING IN THE OTHER TWO 944NA EUROPENA VERSION ALSO !!OR IT IS IMPOSSIBLE !!!I' not one of this crazy kids want that his 944 look like fsat and furius ***** car!!i want a classi car and engine with a litle bid of performance with the technology of 21 century !!nay help good ideas there many people out there asking same question and asking for this performance part with make difference without taking away the reliable and classic look in good care 944!!!!!by the waymy car are 92000 km and 89000 km

Hey,
The BMW is fine car, but still a large one. The 944 is smaller and probably a better handler. As for straight line accleration. More motor = faster.
Now straight acceleration can be measured. Handling is very subjective unless you take to a proper race track. Then it will take a skilled driver to determine which one is better. Then also things like tires (type and condition) current state of spring and shocks as well as fuel level will play a role. This to mention driver preference and the layout of the track itself.
Of course once you start to modify the cars it get 10 times more complex. Good luck, but don't expect a definitive answer.

I really find it hard to believe that a 10hp gain is possible, but if you dyno test that and prove it, I would eat my words.
Also, depending on the condition of the vehicle, that kind of difference is possible, even if both cars were exactly the same setup in every way. A car with old plugs, small vac leaks, tired rings/valves, weak clutch, ect; is going to pull less HP. That could have been the case, too..........

If you get that upset at people trying to help you then no.. There is no way that YOU can get 20hp with $1000, First reason is that you will put holes in the car with your wrench the first time you break a bolt off.. Second is that if you could get 20hp for $1000 everyone on this board would have already done it and someone would be selling it...
Bottom line.. Speed costs, How much are you willing to spend....

Guido,
A lot of people think that you are joking around when you ask some of the questions that you are. There have been a lot of discussions on why or why not to do things. The 944 N/A is not an easy car to get more HP out of as it has been discussed many times. For the amount of $ that you are considering spending will not get you a large increase in power.
Get your car tuned up best you can:
10 - new vacuum lines (all of them)
9 - new plugs, single post copper or platinum
8 - change all your fluids, stick with synthetics or manufacturer suggested
7 - buy a new set of sticky tires
6 - buy new spark plug wires
5 - change rotor if needed
4 - change distributor cap if needed
3 - change your air filter to something like a K&N drop in not a cone
2 - Put some high octane gas in it 91 or 93 if ya got it.
1 - Enjoy your 20 year old car the way that it is. Porsche did a pretty good job with it and you are not going to be able to do much with 1K to change it.
