This varies depending on which generation you're looking at, trim levels within each generation (ex: S, Si, Si 4WD, VTEC, etc.), and what market the car is in (ex: Japan, Europe, North America, etc.).
Yes you can I have 1988 Honda prelude with the 2.0L in it.
It depends on what kind of VTEC motor is being swapped into a 1996 Honda Prelude. The H22 series certainly can be swapped in, as it was in the higher trim lines of both 4th and 5th generation Preludes.
It's hard to say, as the question didn't specify what kind of solenoid are you attempting to fit, and the 1990 Prelude had a mid-cycle refresh which included an improved motor.
Yes, it has an interference motor.
Yes, the h22 is a interference motor.
You could, but because the '94 Prelude is heavier than the '89 Prelude, it doesn't make sense to swap in a smaller powered motor.
Are you talking a stock motor and what year is the car and what motor does it have in it
H22A Honda engine it ready for a turbo
Not without custom motor mount work. Even then, the B series is smaller and has less power than the H series that go into the prelude which means your car will be slow and have terrible mileage. You can drop in an F22 which will be smaller in displacement but still won't have the kind of power the H motor will.
