GT3071R vs. GT3076R pros and cons

[kentuckyslider]

I am selling my gt2871R .64 ar and going with one of these 2. I am keeping my 72lbs. injectors and getting a JWT reflash.

I want the best of both worlds drag and autocross. I will be running JWT S4 cams, topspeed intake, and a 70mm gtiR TB. I want 450-500whp in a SR that can still make power down low. Is this possible. I am running a 4.36 R&P and 265/35/18's on street wheels and the 2871 is always in the boost with the new low gear.

Which would you buy if you were me???????????

anti-lag

3071R will be closest in response to your current setup and 450 is attainable on it. You'll lose some response with the 3076 but you could hit 500 on it. As you probably already know it's a toss up between response and power. Just buy a T3 manifold, test out the 3071R, sell, buy a 3076 and try it out. You might lose 3-400 bucks but you'll be able to feel what you want and that's worth the loss IMO.

30R isnt gonna be good for autox. You would love a Twin Scroll 3071R setup though. There is a video floating around on freshalloy of a guy doing some autox with the 3071R setup. It might be on Full-Race.com too.

What do you do more often?

If you only goto the drags twice a year, keep the 2871

If you only do 1 autcorss a year, go 3076

It's a KA-T that is a monster w/ anti lag and all. Here's his videos:http://youtube.com/user/jgrhoades

^ monstrous

what is this anti lag?

[redtop91]

Rally cars use it, it basically means what it says. It eliminates turbo lag, which was why that car was so responsive in the videos. Before you go deciding to get an anti lag system realize that it's hard on the turbo and engine. Basically detonation in your exhaust manifold to keep the turbo spooling off throttle. FlatblackIan will probably have more complete and accurate info if you are curious.
