i know webcams makes cams for the 5s-fe but theyre very expensive. in the range of $600 (plus $200 core if u go through this mr2 website i found them on. but i think theyre regrinds also but these are probably better than the ones from crane.

however to properly achieve the gains from cams on any car really you need a good header/exhaust system. im running a bosal/brospeed 4-2-1 on the camry with stock cat and custom catback piping on an arospeed bomb muffler. with i/h/e you should notice the cams better. i mean if you notice a little gain with stock exhaust it will be a bigger gain with a better exhaust!

the cam gear they just turned then..ok i see what ur saying.
5s-fes have been known to be strong (mr2 with 5s-fe turbo putting out 420rwhp--full internals/built) but i prefer keeping it all motor. perhaps in your lighter mr2 it will prove to have impressive time gains at the track but because my car weighs in pretty hefty its not worth attempting to stay n/a on it.

good luck with the buildup have u been to the mr2pages.com and camryman.org forums yet? theyre informative and can give you basic help and more.
