I bought about 4 months ago a 90 2.1 si prelude and built a turbo kit to put on with many other mods but the rings went out last week. I’m looking for turbo pistons,rods,rings that will hold up to some good hp but nobody has parts for this motor . The only way I have found to get parts is to get them custom made which is very very very costly. Some body told me that h23 parts mite interchange. So i need a little help here.
