Do you think its worth the money for me to put a weapon R intake (K&N filter) and some brand of catback exhaust on my 95 sunfire? I mean will i be able to tell any difference in power? I mean if i can get an extra 15-20 horse power I would be more than willing to do it. Probably be around 300-400 bucks total.

i wouldnt do it. i have a 96 cavalier that i use for a beater car and that thing is such a wuss it would be a shame to try and make it fast. also is your car an auto?

yeah, its decently fast, it will get up and go if i need it too.

You aren't going to be looking at 10-20 horsepower...

I've got a 95 Civic EX (VTEC) that is similar in size and weight to your car, similar in power I'm sure. Adding the intake / exhaust / header combo frees up between 5 and 10hp.

With my car, it was slightly noticable adding the intake, I hardly noticed anything when adding the cat-back system. I actually didn't add a header until after I added the supercharger, so I can't comment on that.

Mostly, what's cool about it is the noise - it sounds ultra-cool at high RPM's... of course, Honda motors spin to nearly 7500, and it sounds like a Formula 1 racer at wide-open-throttle at those RPM's.

I've never been a fan of loud exhausts - but the intake tube is either loud or quiet, depending on how far open your throttle is - you control with your foot.

Of course, another factor is the resonance of the tube... with the Civic, it's quite long (and mine was a metal tube). With Sunfires, I don't know - plus, you've got a Mass Airflow Sensor that Civics don't have, that might muffle a bit of that sound...
...but that's mostly the reason I'd want one again, anyway.

The power gain of the intake and exhaust won't justify the cost. Dropping a V8 in there may be justifiable, though

My friend and I made our own intake and put it on his 92 Celica. It sounds really good. The PVC pipe was 3" in diameter and was about 4 feet long. Got to love cold air intakes :)

not worth it. no noticeable performance gain.
the sunfire isn't a sportscar. don't treat it like one.
all you'll end up with is a riced out wannabe, in all honesty.

for what it's worth, this is what performance really sounds like:

now, if you were to add hoodpins.. that'd be like 20HP right there.

That's a pretty nasty lope. I'd love to hear that running the 1/4.

I miss the 427

KIKI,

Why did you have to post that sound clip. Makes me want to run to the garage in the middle of the night and fire the Cuda up. BTW sound really good, you have a solid cam in that.

yeah I only revved it to 3K in that. I was sitting in the garage and with the pipes out the sides in front of the back tires, it smells up the garage very quickly. haha

makes power to about 6500RPM though, revs to 6800 which is damned good for a bigblock.
