A&Q about 350Z
Q:
As far as power, is there a noticable change? Like would they give you a combined power boost of something like 10 HP or is it minnimal... like somewhere around 2 or 3 HP?
The car I want isn't really meant to be a street racer or anything like that. It just has a 7.5 0-60 time and I would like it to go a bit faster. (like ~7.0 seconds)
A:
What type of car? Different cars can respond very differently to an intake and exhaust. The Focus, I know sees a usual gain of about 7-8hp total for both mods, that being on an othewise bone stock motor.
A:
Its a Stratus 2004 with the V6. (2.7L ... not the mitsubishi 3.0)
I doubt it has room for a turbo or anything fancy like that... which sucks
<--- under the hood
A:
Without knowing much about that engine, I can't really tell you how much it will help...are the Stratus forums dead here? Search around on Google for Stratus forums, or different companies that might make parts for the car. I would imagine any gains would be similair to most cars, but again, I can't really say without knowing anything about the engine.
A:
Exhaust tuning is much more beneficial than intake tuning. there is only so much air your engine can bring in, but a zero loss exhaust tuned to your engine can drastically increase the power output.
The problem is that your car isn't really a performance car... and thus, will not have aftermarket. You could build an exhaust for it, or have one custom made... but on an engine built for mileage before performance, i'm not sure how much power you would get from it.
A:
well, it all depends on how well the factory built the exhaust, how big the engine is, and how much power it already has. If you have more mods on your car you will probably see a bigger increase. but you might also notice some changes at the pump as well (depending on how you drive your car), a free-flowing intake/exhaust will help fuel efficiency. and what are you thinking of doing? is it a whole intake and exhaust upgrade (cold air intake, filter, new heads, headers, high flow cat, cat back exhaust, camshaft, valves) or something a little cheaper and easier (cold air intake, headers, catback exhaust and mabe high flow cat) because you will notice a bigger difference on the more involved upgrade but it will also cost you a pretty penny.

Yah I deffinetly dont want to do anything with the camshaft or valves. I have no idea what headers are but someone told me dont even bother with a new exhaust if you dont get new headers. Lol I sometimes like to race people at stop lights and things like that, but I dont think I would take the car out to a racing event or something (Lol it is a sedan anyways...)
I Just enjoy flooring it every once in a while, and going fast... but this Car is limited at 115 MPH
Well actually I dont care so much about the speed as I do acceleration. (Its 0-60 is 7.5 seconds)
How much would a new intake and exhaust system help in fuel efficiency? Is there a chance it would actually lower it?
A:
There is a good chance of increasing the effiency with some well thought out and executed intake and exhaust mods. Just as there is good chance of decreasing it with junk mods...
A cold air intake and good, free flowing exhaust, will improve the performance of your engine and "should" increase effiency. Adding a high performance ignition will also help.
The other factor to consider is your right foot... This new found performance can be detrimental to "effiency" if you can't keep your foot off the floor board, always going for those 7.0 second 0-60 times...

A:
I would say 10-15 hp from a quality aftermarket intake and exhaust. Different cars vary and its hard to say how restrictive your stock intake and exhausts were to begin with.
