Default So I am at 450 horsepower with heads, cams, all bolt ons. Fast 105 and 105 TB gains?

So im at 450 rwhp with my vette, 2002 model. PRC stage 2.5 heads, 228r cam, full bolt ons.

Could I expect noticeable gains with a fast 100+ ported intake and nick Williams throttle body? 25 or more horses?

I figure the ls6 intake is perfectly matched for my app, but just getting some input.

consider a fast 92mm intake TB combo.it would be cheaper and easier to install.a fast 92 mm intake can add 15 hp over a ls6 intake .the fast 102 intake is good for 5 more hp over the fast 92 mm intake.a 102 mm TB is harder to tuner and requires grinding or replacing the water pump.you can retain you stock coolant lines ,they can be fitted.

^ AGREED!!! A tony Mamo FAST 102 could net you easily 25+ HP. If your going to spend $850 on a 92mm you would be and idiot to not get a 102 for CHEAPER. 102's are superior runner design, regulardless what people say they shine on motors such as yours and dyno #'S don't lie.....

I say 102 as well. However, I have heard horror stories of fitnemt issues under the cowl of the c5. The 92 fits under there better.

I wasn't aware of the clearance issues with the cowl.

Does anyone have any information or pictures that show what is needed to make it clear?

I bought a 102 from an elderly guy of corvette forum who had his on a 102. There was a small run mark on the back of it where it was close to the cowl but it fit.

I wouldn't go with a 102, the fast 90 and throttle body will help to get you there without the fitment headaches.
