i need to know something

i kno its possible to use the 7M-GE cams in the turbo model

and i know this would be an upgrade b/c the cams are more aggressive but have a serious question.....

b/c the Cams are more aggressive will i be able to run my car with them, with out changing anything in the valve train system of the Turbo model...

It's a direct swap but no really ideal on a turbo car. Turbo engines get going at high RPMs. The NA intake (i believe it's the intake is different and the exhaust cam is the same on both engines) cam is for more low end power.

Lift and duration are the same between turbo and n/a cams.

Its just the timing that changes on the intake cam.



You're better off just buying adjustable cam gears. You will be doing the same exact thing, possibly more. But much easier to install.

NA cams are a worthless "upgrade", all they do is shift the power curve and completely choke the top end.

search some people have had problems (with the exhaust side i think) not sitting right and leaking.

n/a engines have overlap and turbos do not like overlap as you will push fresh boosted air right out the exhaust and loose power.

Okay? What about them?

I was referring to the OEM camshafts.

There is a sticky about this already in the technical section.

Oem ge/gte intake camshafts have slightly different lift and duration.

Can't find the specs at the moment but i'll find them later. The n/a's cam can be adjusted so that it works better in the upper rpm range using the 4 degree advance dowel hole in the stock cam gear. (or get adjustable gears)
