I was looking into buying a 93 SI hatch, and swapping a new engine. I found this one engine form a prelude H22a R. What kind of prelude is this from? And would it be a good idea.

 

There's no such thing as a Prelude "R". Where did you find this engine?

on the selecter go to 93 hatch si mt then hit search it gives you lots of engines. The first one is called H22A R

 

That particular website listed the engine name wrong. The specs for their "H22A-R" are the same as the specs from the Japanese Honda Prelude Type S engine. They have the 20 horsepower difference (220). I think it was just a type-o that's all
