Hey guys i recently purchased a head from another member here on SM, and its in the process of having a pretty decent port job and cleanup. So the question is are there any advantages of running the NA intake cam, i checked its TSRM specs a while back and it was saying it is a smaller cam than the turbo cam???
NA intake cam on a GTE???

I wouldn't say "it blows ass" 
The power/torque curve does flatten out above 4000 rpm or so with NA cams...max HP is achieved with turbo cams. There are a LOT of other factors that determine what you can get out of the motor.

Turbo motors need top end support from the cams... If the cams fall on their face at mid to high rpms, I would define that as blowing ass.
Meh. There are other ways to help that out. The NA cams DO bring the power band down, which results in less peak HP, but a broader power band. It does depend what you want out of the car.
The NA cam doesn't so much "fall on it's face" at high RPMs as simply not being as well optimised for it. There's not as much lift (Though a GOOD NA cam will still be better than a lot of worn turbo cams are) but there's a bit more overlap.
I personally wouldn't use an NA cam, though some have used it as an upgrade, and have shown improvements on the dyno, with a slight falling off at 6000 RPM. It's low end response IS better in daily use on the street.

Yep, much more of a big picture view of what NA cams do vs a rather narrow definition...Well said Dan
