welcome 92accord2_2. ok as for ur first question about the wheels, before i get started.... you don't need to worry about those "wierd bars" that hang over both rear wheels, and for future referance they are called UCA or Upper control arms, the front has them too, they hold the wheel up. ok so you can get anything that you want, because those bars will move out of the way when you lower the car, they pivet up. next the difference in Generations of accords, is basically just the body style. 90-93 (YOU) -4th gen 94-97-5th gen 98-02 - 6th gen 03- 7th gen. so thats it with the "gens" as for the motor.... hell yea there is more power. you have quite a bit of options. you can get the H22a (prelude/ accord type-R motor DOHC VTEC ) H23a ( Prelude motor DOHC VTEC ) F20b ( accord euro-R motor) and much more. but you will be getting anywhere from 170-210 hp with these motors, instead of the 135 you get out of urs right now.... yourwelcome... feel free to ask me anything and i'll help you best i can
