I'm trying to decide whether to do ARH LT's or cams this year. Next year I'm going to whatever I don't do this year and heads then forged internals and blower in '09. My question is will the stock headers and H make cams worthless untill I do LT's and O/R H? One of the new guys at the barracks is big into cars (VR4's and EVO's ), loves to work on anything, and has a lift and tons of tools so all the labor will be done for free or some beer. I know I'm killing the warranty by doing the cams but I don't really care about that.

 

LT's are not mandatory with cams but they would give better breathing which will yield better gains from cams.

 

Agreed. Do the headers first. You will get more benifit from the cams later with long tube headers already installed. The ARHs are comparatively easy to install too. You can do it at home with the car on jackstands.

 

Have to agree... the longtubes are a must for the full affect with the cams.
