I'm new to the site so if I sound like and idiot...
I have a 98 12 valve 4x4. My current mods are 80 hp fuel plate, 370 marine injectors, 5 in exhaust, open element air filter, stock turbo at 44 pounds of boost, Triple Loc convertor, suncoast rebuilt trans, ats valve body, T/C lock switch, pyro and boost guage.
The truck is pretty quick I think, I know it's nothing compared to most of you guys, but I'm looking for a little more. I have a little over $2k to spend. I know I don't have much longer left with the turbo. I was thinking about a BD super B turbo, Snow stage 2 water/meth injection, and a S&B intake. I'm leaning toward the BD because I would like to go to twins when I get some $. And I heard they are a nice set of smaller twins.
What do you guys think? How bad do you think I would be pushing my HG and head bolts? I know it will have to be fire ringed and stuuded sooner or later. The reason I ask is I'm going home for my b-day and the guy I bought it from has a duramax now and is confident he'll beat me in a race. I gotta whoop him, for me, and for CTD's everywhere.
Thanks alot any info would be great!

 

The Super B turbo would work well with your setup. They come wastegated at 40-42 psi so you shouldn't have to worry about your stock headgasket.

 

Even with the meth?

 

I think you would be ok with a smaller single and water/meth. Personally, I wouldn't worry about the water right now, and I would go with a larger single(Phat Shaft, s300, or something cool from J.R.) and save your money for head prep that will be needed when you go to twins. J.R. Adkins' number is 317-281-3130.
