list your most successful performance upgrades and your recommendations.. im looking to add some horsepower, but not spend hundreds on single digit gains..

Im looking into exhaust manifolds, cold air intakes, flywheels, and ecu mods.. but wanted to hear success/problem stories beforehand..

I have a 9lb flywheel for sale, very good experience with it, also have S4 cams, best bang for the buck imho (+12whp ish at peak).

Pulleys are also good (hard to find though), cai (hard to find), SSAC header (ebay), any 2.5 mandrel bent cat back will do.

Save your pennies and turbo it. Nothing else will make your car feel fast.

If you had a p10 then I would say full bolt ons because you can can probably get about 180 crank horsepower and that would feel pretty good in a 2600 lbs car. But even if you could get your p11 up to 180crank hp it would still be kinda sluggish.

Those cams won't work in your car and I don't know about the flywheel. I think it will though. If your paying someone to install a flywheel then I wouldn't consider it a good bang for the buck. Labor is expensive for a flywheel job. Just wait until you need a new clutch to get a new flywheel.

You're going to get flamed for asking this without searching, since there's a huge Sticky that lists nearly all power mods and what to expect of them. My favorites have been advancing my timing (free), and a header and cat back ($150 for the header and $255 for the Cat-back). The CAI was underwhelming, but I realized that for it to do any good the car would benefit from better exhaust and an ECU tune. Without a tune or without going through and upgrading all components related to the engine's breathing...you are going to get only temporary gains that the ECU will compensate for in some other way. Mine is an OBD1 P10, so that's less true for me than for you. Basically, a turbo-swap would probably be your best option.

but there are cams available for the p11, i just wanted to know if it was something to look into. Me and a friend of mine swapped the cams and the exhaust and added a SCT chip to his 99 ford mustang, and he got decent power gains, but all cars preform different and there is a big difference between a V6 and an I4.. especially when it comes to exhaust..

yeah cams are a great mod.

everything you listed is a good mod.

instead of posting hey is this a good thing to do post what you use the car for and what your realistic budget is, and also if you will be doing the work or if someone else will.

yea, i know, and i did do the search beforehand, but what i really wanted to know was how everyone that has installed various mods has liked them, not just that they added a flywheel or a cold air intake, but did they actually gain anything from it.. and was it worth the cost

I spent thousands on my 240. I did exhaust, intake, gutted cat, short shifter, etc. I bought all brand new stuff top of the line and even had some stuff imported from japan. The car felt quick but was still slower then my buddy who threw together a junkyard turbo kit.

So my next car I said "I'm doing nothing but turbo". Well that's what I did to my G and I never regretted it. I even kept the stock injectors, exhaust, and MAF. It cost quite a bit but was worth every penny.

well i use the car as a daily driver, but i would enjoy a little extra power because i do play with it sometimes.. and as for a budget, i would say around 1000 to start with, but if i decide to Turbo it i could save a bit more..

but for the money i would spend on a turbo, would it be better spent on a few things. rather than just one?

And 95.. i would do some of the easier things myself.. intake, exhaust etc..

but if i went for a turbo, i would have to take it to a shop.. i don't have know-how to risk messing up a turbo install haha

under 5k. I did no work myself and bought all brand new parts. So don't let my number scare you. If you have another car to drive in the meantime and can do the work yourself you could do it for about $2500 I would assume.

^if you want you can just lighten the stock flywheel...it shouldnt cost much maybe 40$. might as well put in a new clutch while your in there. i would think a good shop would charge about 700-800$ to do the whole thing new clutch and lighten the flywheel.otherwise aftermarket ones go for 300$ around maybe cheaper.
