after looking through some of the performance posts I noticed a distinct lack of posts concerning certain modifications that I think would be quite straight foreward. Just wondering if anyone has attempted them.

First off, has anyone attempted to port and polish the stock throttle body? I know in a lot of applications opening up the TB by a few mm helps to greatly increase performance, especially coupled with a performance intake and headers. Along the same lines, what about porting the MAS? I know it's a tad risky, but can be done. I have yet to really study the intake manifold, but is it capable of being ported or at least gasket matched?

Then what about actual valve train modifications? Someone has to make a cam. What about getting cam blanks? I know crower will grind grind just about any pattern into a blank.

I'm also sure someone has had their heads ported and shaved. That has to be good for some power. Kind of like running the non SC heads on a SC engine. Also what about scavenging parts from other engines? Is the 3.3L block used in any other configuration that may have a better head or cam set up? Even have the potential for a stroker crank or a bore job?

it just seems the bulk of the performance here is CAI, ASP pullys, cat back exhaust and a mention of headers and computer flash

:edit: Found that Nissian Performance makes an "off road" cam for the VG33E engine

"The cams have 264 degrees of duration and .430” lift with a 106 degree intake and 116 lobe center"

They claim up to 40 HP gain over stock and a lopey idle. Don't know if I believe that, but they would be good for at least 20. Would be nice with a set of headers. They just have problems passing emmissions.
