Budget/Efficient power adders for 96 Altima

a freind of mine has a 96 altima that my freinds n i use to taunt 'Stangs n out run them (well, more like deceive them into thinking we'll turn 1 way, then go the other). :evillol: believe me...she is an awesome wheel-woman... :sunglasse ne way...what kind of things should she get to add acceleration(low end torque). she was thinking of the SR20DET engine from a Pulsar...would this fit her car? what about basic things like an intake or exhaust. budget is a very big thing here...like less than $250 per upgrade...she just wants better accel, and a lil higher top speed...97 MPH on the freeway...sad...

wow thats slow my stock 94 tops out at 126Mph.
I didn't realize that nissan handycaped the 96'es that much.

The '96 Altima isn't that limited. I've taken mine to the max reading of 120mpg several times on the bypass and interstate and I get the feeling that it'll go faster.
