what is better between the gt3540-.63 and the gt3540-.82 which is better??
looking to buy a atp kit, meth injection... and building bottom end

 

What kind of driving will you be doing with it? The biggest difference is going to be spool-up time.

 

STAY AWAY FROM ATP... their kits are terrible and don't put down the power they should. Stick with someone reputable

 

What cams are you going with?

 

I don't have experience with their 35R kits, but the ATP 3076 kit absolutely did put down the power "it should" for me. Spool up will be a little later, but that's the price you pay to save ~$1000+

As far as backsides go, I'd think you'd want the .63 to get it moving before 5k

 

i just wanna go fast such as 10sec 1/4's n its everyday driver so nothing huge... lol just around 550ish

 

ATP will not net that kind of whp easly. You need a proven kit with a tubular manifold.

AMS,ETS, BUSCHUR,AGENCY POWER, FULL-RACE

Heck even JDM Brands are better than ATP
APEXI,HKS,GREDDY

Research will be your best friend for going big turbo.

Good Luck

No Way, ebay kit all the way.....

no offense and I know that all of us are not made of money but please remember that you are driving a $30k sports car. why would you spend the money and build the bottom end and then go with a turbo kit which is widely known for not performing?

Much better options out there, if it means save up for another 4-6 months to get a AMS Kit or ETS kit then do it. But for the love of god, don't do that to your baby.

Why I chose the AMS Turbo Kit
