I have a first gen SI.
I was thinking of having the motor rebuilt...
however was thinking of putting a diffrent motor in it. what is a good motor transplant?
how about suspension?

 

I have no idea how much difference there was in the engines but I used to have an 86 prelude si and I loved it. It was only about 110hp or somethin but it felt like it accelerated a lot faster than my 97 civic does. Speedometer never worked so that could all be in my head but fun car regardless.
