a lsVTEC done right will smoke type-r's. but that's done right (BC valvetrain/toda/Skunk2 ex + Type-r Rod/pistons/rings AND a good tuner with a good program). but ur lookin @ an extra 1.8 g's +/- for these parts depending on where you get them & thats not including installation of the r/p/r into the block. gs-r is much more reliable and cost more than an average lsVTEC setup.
i'd fully build a gs-r motor in my opinion. I'm not sure if you're also on Honda-Tech, but my room mate builds lsvtec motors, names bambam on Honda-tech, he built the very popular thread, "How to Build a Reliable Ls/Vtec" and he'll hate me for sayin that.
