I have a '89 prelude 4ws and want some more power from the B20A5 that is in the car now. What wold be better for this motor. I have found a couple of kits online (all Super Chargers) from http://www.ludespeed.com and http://www.theoldone.com (not released yet) and sound like good power gains from both. If I do invest into a Forced Induction unit I want to strengthen the internals up what parts are good for this much power/pressure and who sells them. Any info would help.

Thanks.
