2G Evo 3 cams in a gsx

[latkins09]

will evo 3 cams be an upgrade over stock cams in a eclipse , if so can i use the stock valve train and just swap the cams

you should be able to bolt them in with no issues.
I'm not certain if the cams will be any better, but you could measure the lobes and calculate how much lift they have.

Heres some good threads on the subject [see links below]
