I tried to buy my bros Integra before I bought the Mustang. It used to have a built LS VTEC but then he swapped in a stock LS engine and bolted on a nice turbo setup... ended up blowing that engine (was used, abused, and had some miles on it). It still ran after he blew it up, but it sounded and ran like total ass, puked/burned a quart of oil every few minuts...
They are fun little cars though. They handle like crazy, and can be quick/fast with the right parts. I liked the VTEC though, it came on very hard on his engine in the 5k zone. Whole different exhaust note, car started pulling hard.
The turbo was fun also... it made for some good fun when the boost came on.
Hes still got it though, hopefully Ill get to mess with it sometime.
