I have a good project for ya..
**Get a b13(91-94 nissan sentra se-r) stock motor{sr20de 140hp/140torque} 15.8 1/4 stock
....You can find one from 1g-3g locally. Sentra's, Infiniti g20's, nx's, nissan 200sx's/ser are doable too but the infiniti g20 is a 4door/heavier.
**Get a Neo VVL{Vtec} sr16ve OR sr20ve motor for about 1500. {170-180whp}
**Add some bolt ons and a Ecu
**Tune it
**You should be able to hit 13's in a quarter mile and be around 200whp all motor.
**Shoot some NOS or Add a turbo; who know's! {sr16vet/sr20veT}

Or {if you don't wanna be all motor}
**get a GTI-R {turbo} motor & swap that in.
**13 seconds automatically depending on health of motor and build.

4k is doable with all this; anything besides motor work, you'll be spending for looks.
