Im running into a lot of money (for a 21 y/o student) this summer and im thinking of going turbo. What are supporting mods for a turbo setup? Do they differ from a s/c setup? Can i just go turbo then add supporting mods?

What is your ultimate goal? You already have an L67 which can be modded quite well for the price of a turbo. But like my question says what is your ultimate goal?

if your going turbo you should get the FULL kit... intercooler and boost controller and also you will need bigger injectors.. I would get a cam and you will need to tune for sure... but the kit comes with everything else you need

I think you should save your money on a turbo and go for the intercooler, cam it,and stay with the blower. You are going to run into some problems with the turbo if you dont know the in's and outs of how to tune a turbo car. With a blower, an intercooler, and a cam all you need is the powertuner. And you will see some very good numbers.

I want to run mid 11's and trap around 120. I havent seen any gp do this w/o going turbo. This car will no longer be my DD. See I just finished school and i'll be working as an EMT this summer I will be making around 40k in a 61/2 month span. I only spen around $650 a month on bills. So I want to do something big with my car....especially with all the ricers out here, they dont really know the potential of a gtp

Mid 11s is very doable with the S/C.

ok figure just cam and teh supporting mods youll get hig 12's
add heads and yoru mid 12's
add a chiller and your low 12's high 11's
and still less than a turbo and chiller

how much am i looking at here? i was planning on spending 5-6k, but i had some cosmetics included in that amount.

Try something different go with a whipple and supporting mods the sound is incredible and I think you could reach your goals .Chico.

the whipple is like $4k! I looked at it but i think (correct me if im wrong)that i will see more from the turbo and it cost less

I found this clip of a whipple charged gtp
Sounds insane. I might do it just for the sound. what supporting mods do i need for this?

To take advatage of the whipple I would say P&P heads,cam and headers.Chico.

Damn that whipple sounds like a police car.

omg i want a whipple

Here is my though.

If it isn't your DD anymore and you have another car already:

1) Beef up the tranny with zzperformance.com tranny upgrades. Your tranny will be in danger with 11s.
2) Either the Cartuning Turbo kit or the ZZPerformance turbo kit.
3) Intercooler.

Not 100% sure this will give you 11s but based on feedback I heard from others with this setup, it will definately give you 12s. You may have to get the additional items as suggested like cam and heads to handle more boost.

If you don't have a 2nd car just yet. Recommend saving for a downpayment for a REALLY nice car/truck. Save enough so your monthly payment is a joke.
