No, the 88 and 93 are a different chassis.
Yes, I actually bought a 93 accord trans for my 96 prelude. The 91-93 accords have the same engine and trans as the 92-96 preludes.
They should, as there weren't any major mechanical differences between the two.
Provided the '97 Prelude is a base model, then yes it is possible to swap in an H22a variant. The Prelude Type SH motor is different as the ATTS unit is connected to the motor. So, the only compatible H22a motors would be one from another Type SH, or the JDM Honda Prelude Type S motor.
yes
poor gas mileage
main relay
balljoint or control arm. Or possibly CV joints had the same problem with a 92 prelude
Check your owners manual, it will tell you in that.
It depends on gearing, aerodynamics and if the car a limiter(most due now a days, atleast in the US) An example most VW's now a days have 200hp and most are limited to 130mph. compact/mid size cars would see around 140mph 1995 prelude 2.2l 190hp - 140mph 1995 nissan maxima 190hp - 142mph
The IAT sensor on the 1993 Honda Prelude is located to the right of the intake manifold as you face the engine compartment. It is connected with red and green wiring.
find the belt tensioner and use a rachet to oush the tensioner back
