Should I go for 19% GIAC oand injectors? Or Intercooler [FONT=Arial]and Big Valve Cylinder Head[/FONT]

 

I say 19/GIAC and injectors

 

Why not do both? The Giac and injectors is only ~$600 more and you can easily install these parts while doing the others.

 

Hold off on the intercooler! Spend that money on better things. What are you plans for the car? Do you track it or autox? I would say go for the 19% and maybe the tuning and bigger injectors if you plan on tracking the car or plan on beating on it. I spoke with Eric at Helix and he said the tuning and injectors were not needed for normal street use. But if you wanted to get tuning then injectors are a must! Oh and I highly recommend Eric @ helix!!!!

What is the definition of "normal street use"? Probably not the way I drive, or you either if you're thinking about these mods. I had just the 19% for a couple of weeks, then added the jcw injectors and GIAC. BIg difference. The power was smoother throughout the rpm band.

Ask Eric about intercoolers. He believes that the stock one is about as good as any out there.

My $.02

 

You can probably qualify "normal street use" as not driving between 5K and 7K rpms constantly. I'm sure there's a more technical definition.......

 

Eric told me the same thing on intercoolers. He said that you are wasting your money and the stock intercooler works well! He also mentioned about keeping the stock plugs. He said you would want your stock plugs to fail before your pistons fail!

 

I did the 19%, GIAC and JCW injectors on Monday at Helix. Couldnt be more pleased. Although, the high pitched SC whine takes some getting used to...
Worth every dollar!
