I am thinking about adding FI to my truck. I need a kit that builds alot of power but can be added to later for more performance. How much fab work is there to be done with the STS kit? I have always liked turbo vehicles, I used to have an Audi S4, but I am wondering how long my trans and rear end will last with the kit. I will be driving my truck everyday, hunting out of it, and towing my 22 ft ski boat. I am assuming that I need a stall converter, which I was going to do regardless of whether I get FI. If I go with a 2600 yank, can i still use that one if i get an STS or radix?? How "turn key" is the STS kit? Does it come with everything that I need? How much power can I expect from the basic kit? Thaks alot.

 

the STS kit is pretty easy to install but does take a little time to do it right.Youll need some larger fuel inj. and either a boost a pump or a larger fuel pump, look at my sig, i run a 2800 stall and truck runs/drives great.drivabilty is great, you dont know its there at normal cruising till ya punch it.youll also need a tune of course.

 

I have a tune already, do you mean that i will need it re-tuned? Also can i get buy with my 4l60 and my rear end? What needs to be fabbed in order for it to work?

 

YOU should get at least a shift kit and servos, the kit will reduce heat in your trans allowing it to last longer, stock rear is fine for our trucks, sometimes the G80 fails but mine works fine.yes, you need to retune for the turbo system, no big deal for a good tuner.but you need to watch your fuel values and timing under boost just to make sure things are safe.

 

the turbo is a little more forgiving on the drivetrain over a supercharger cause your not at full boost till 3000rpm, where as a charger is instant high tourque from a stop,
