Alky will allow for more timing and more boost (aka more power) on ANY setup.
You WILL want to get a chip specifically for alky because that's where you get the programming for more aggressive timing and create more power. Running it without the chip is not taking full advantage of the alky.
Other than that you don't need a bigger turbo or anything to enjoy its benefits.
Only other thing you might want is an adjustable wastegate actuator or boost controller so you can adjust your boost level and turn it up.
on a 100% stock car alky will cool the intake charge those creating more power. you dont have to up grade your fuel system or injectors to run the alky kit.
If I was starting from scratch on a stock motor, alky would be the first thing I'd add. Then a chip (for the alky and to up the boost) , K&N and exhaust upgrade and you'd have a great running car. Paul
With any engine being run.. get that fuel pump in there, a chip, and scantool.. confirm things are as should.. then you can turn the wick up with the alky kit.
I've installed the kit on too many stockers come to find out the OEM pumps dropping fuel pressure. Once you have fueling.. the car will wake up big time.
