which car is faster

So my friend has a 2002 nissan altima 3.5 v6 engine, it has an aem cold air intake, cat back dual exhaust, "tuned" ecu chip, and thats pretty much it engine wise, also a 2.5 suspension drop. My car is an 07 cobalt 2.2, so far its stock. Do you think that with a short throw shifter, new intake (SRI or CAI), 2.4 swap, crank pulley, alternator pulley, zenn lowering springs, sway and strut bars, that I would be able to beat him in a 1/4 mile drag race. He pretty much brags how fast his car is and that when I got my cobalt it wasn't gonna be faster than his since i didn't get an ss. Please help me out here guys.

Here's what I see...his car has the VQ35 which even though that was the first Altima with it (240hp), it was a pretty quick engine. The Altima isn't that big...it weighs in at ~3250lbs. So he's got an auto with about 4-500lbs more than your manual coupe.

He's got the basic bolt-ons with a tune. That would net him maybe 260hp crank. Drivetrain loss probably means he's around 200whp. That's saying a little more than 20% loss.

You've got a stock car....yours is 145hp at the crank and maybe 125-130 at the wheels. You've got no chance stock. You'd have to add intake, intake mani, full exhaust, tune just to have a chance. You may need more on top of that though.

And, as far as the intake mani goes...there's no point in adding it if you aren't doing intake and exhaust. A tune isn't required for just the mani, but if you go to the 2.4 throttle body, then you need the tune. A tune is a good idea with the manifold no matter what though.


My wife has an 07 Aura XR....3.6L 252hp stock with 6-speed auto and paddle shifters. That thing will do 14.5 in the 1/4 stock. I'd have to add a lot to my car to make it come close (but I have an auto as well).
