What is the first thing that you should add to mod your car

[JE123]

I'm looking for a fairly cheap mod that will boost performance. I have heard that a K&N air filter will add 18 hp, and they are fairly cheap, aren't they?

18 hp to a 1990 oldsmobile? I don't think so , i don't think that it will add so much to any car... A real racing intake with cone filter and intake in the hood , with mods under the hood to keep the air getting into the filter the coldest possible... If we're talking about turbo cars then any boost controller will do the job...

I agree. Get a K&N filter anyhow. Jut for the fact that you won't have to buy another air filter. That is the only reason I bought one. I have been hearing a lot about this Tornado device th8at you put in your air system that has been proven to give up to 25HP on certain cars. They have a list of what kind of increase you can expect on some common cars. Hell I added 19HP to a newer Chevy Impalla.

Also you might want to get yourself a cold ari intake. The colder the air the more power you have.

do the air cleaner assembly up with K&N, and re do your exhaust system.... that doesn't just mean a new muffler and tip. to take full advantage of airflow, and reduced backpressure, put in header(s), mandrel bent headpipe(s), hi flow cats if applicable, mufflers, and tailpipes. mufflers and a tip alone don't realy do a whole lot if you're still using factory 2", 1 3/4" or worse pipes and manifold ahead of it.

As has been mentioned above, I’d go with a new exhaust system and a pod filter. I’ve got a 3” catless exhaust and a Trust Airinx pod on my Skyline and it goes like stink!

Lol, its a Skyline FTO, thats what they do

ANy how, I agree with everyone else, let your engine breath better with pod filter, intake, downpipe. It all depends on how much you want to spend. I'd do it in this order:

Air Filter
Intake
Downpipe (If you have a precat)
Exhaust, either high flow cat or no cat.

Also you might want to consider performance pullies, sounds silly but it helps a little

True, but my FTO also went HEAPS better when I put a new exhaust and pod filter on it.

I'd imagine so, did you do anything else to the FTO?

Nope, that was about it. I was thinking about headers as some are in the process of being produced for the FTO, but I bought the Skyline before I got around to it. The only other thing I did was add a front strut bar.

If you want to stay cheap you should change the air intake and put a cold air sys with a k&n. And put a cat back. All this should give you maybe up to 20HP. best would be to change the headers but that is more expensive.

No cat huh, lucky people that don't live in the states.

[Firebird]

yeah living in the states theres a lot of stuff you can't do especially in California (those guys get screwed) I did however read somewhere that removing the c-converter actually lowered hp and torque a small amount (about 3 points a piece, barely noticeable) I stayed legal and went the high flow route for the converter I bought a Catco one it has really low restriction I think it was fiber glass lined (like a big glasspack) It all burned up pretty fast and now the car is even louder than when I first put it on.

i live in arkansas. i can cut my cat off and nobody would care. hell i could cut off everything and just leave open exhaust valves if i wanted to. :silly2:

No problems with it here either , i know a lot pepole who have straight pipes on a Vw polo 1,4 75 hp 4 banger and think they're all that , i was once driving with a guy , we were driving back 500 km in 30 hours... man , he has straight pipes on his corolla (euro model , WRC - like) his corolla has a 2.0 turbo engine and 4WD in this , but there was so much snow that we had to go 20-40 kmh all the time , and i thought i'll be deaf after this trip , this kind of exhaust is really annoying on long trips...

[LjasonL]

yeah my friend has open pipes on his accord (cuz the muffler fell of when we were mudding) and its really annoying u can barely carry on a conversation.
