the cheap one you were probably talkin about was the vitara piston/eagle rod combo. look up jfk78 on hater tech, or fjdistributors for kits.. there's a LOT of info on these, and numerous 400+ HP builds out there... jfk i believe is the current record holder at 484 or so, on a mustang dyno, which from what i've read, (being that i have no actual experience in this, and will be the first to tell you that all my engine building info is only read about) is a little over 500 on a dynojet.. and if you find some, make sure they're YCP brand, because the nippon racing pistons are horrible... again, from what i've READ, you may want to consider going .020 over and get some 75.5 vitara's because of piston slap in the 75's.. good luck with it!
