everyone has the smarty and i know that it increases performance so what are the numbers in hp and tq that i could get with the stuff i already have in my truck and what kind of boost increase could i expect with it on my stock turbo

 

If your wanting HP # on a smarty/comp stack, I'm going to say little to none. the curve will be flater. I just don't like the smarty/comp stack, as well as the smarty/tst. JMO

 

so is the smarty/tst combo stronger down low or up high or good all the way along? and i still have the stock turbo and gettin a extra lift pump

 

your stock turbo was tapped out with just the comp. add in 110hp injectors you already have and now wanting a smarty....your money is better spent on more air, cooler air.

 

well ive been reading on here people building their own twin set up for cheaper than getting a single...if i changed turbos would the intercooler and headstuds need to be swaped as well?

 

I agree with pgilles that you need air more than another box.

Intercooler should be fine at that point, but studs are always a good idea. I've been running a phatshaft turbo for over a year w/o studs pushing 47 lbs of boost and the head gasket is holding with 160+ miles on it Long term, plan on studs; short term you *should* be fine without but no guarranties.

And you're right there are lots of guys runnings their stock turbo over a htb3 or s400 turbo with good results. There's also some great singles out that can support simular power.

Looking at your sig it looks like you need to adresss your fuel system so get that done and start shopping for turbos and saving for tranny parts. This is about to start getting expensive so beware

 

ya im not looking forward to having to drop that much cash but i know that after i do it i will love it and be able to smoke all my buddies..hey yall really r helpful on here yall dont support a certain company yall just say what is the best KEEP IT UP!
