i am going to keep working on this truck and see where it goes. i am ready to buy my next turbo/turbos and need to nail down exactly what my new set up will be. i just got a tig welder and a few other metal working tools in the garage and am going to attept to fab up everything i need myself.
i have a 2500hp rated air to water intercooler deal in the works so that will may effect the set up. i will likely be going with the single plane intake set up and larger TB. not sure what i am going to do with the fuel system yet. i might just keep running what i have for now. a meth kit turned up prety high and 8 96lb injectors with race gas in the tank when i am going to push it. i think there is another 200+rwhp in my existing fuel system.
so now for the fun question. what turbo/turbos should i be considering. i would like to be able to eventualy get to the 160lb range at around 30psi or a little over. if i do get to that airflow it would be nice to not be maxed out. an airfilter would be nice. i have room for twin 3.5" dp's if i run twins but it would be more work to fab up twins. i could run a 5" dump if i run a single and just cap it and have a 3" pipe out the back for street duty. this is going to be a tuff decision. i am not real concerned with lag, i will likly up the stall a little and spray whatever i need to to get it going.
would there be anything wrong with going with a pair of basic t70's? i dont know that much about all the diferent turbos out there. isn't a turbo like the gtq72 a lot more money and would it be worth it for my set up?
what are my options for singles if i want to run a filter or would i be forced to cheese something up? would twins really spool any faster than a single?
i know i have a lot of other things to work on in the truck to even use the power i have but who cares. it is more fun making more power so thats what i am going to do.

i am going to get a proper intercooler and a good intake in the process. that should help things a little.

i am looking all over for turbo maps, it is hard to figure this stuff out. i am leaning toward a pair of t70's, just big enough for my stated goals and if i ever happend to max them out a pair of 76's should just bolt on.
would a PT76GTS bolt right in place of a pt70? >> if so that would give me a range of 1600hp with the pt70 up to 2400hp with the pt76gts with just a turbo swap. heck if they are interchngeable i might even start smaller. maybe a pair of 66's and see what i can do with that.

Chris Chow has a 394ci Bob Reiger motor (built by Duttweiller) in his '87 Buick GN (WE4 actually) that originally made close to 1800hp (it went 6.70's@206mph in an S-10 with (2) T-100's I believe).
Now with this motor in his 3500lb+ GN and with (2) T-76's it went 8.0's@170mph+ and 3.5" downpipes and TH400. He then stepped it up to I larger turbos and 4" downpipes/powerglide and has now gone high 7's@180mph with the stock style rear G-body suspension (Wolfe setup) and 9" rear!
Twins will come into boost earlier and spool faster... and make it a big more "streetable" if you can even call your truck that at this point
.
You are a madman!

the GT-42's have a 5" opening so getting an air filter is harder.
i know the PTE-74, 76 and 88 all use the same compressor cover, not sure on the 70 though, you could take with Jose to see how interchangable those turbos are.
but if your concerned about running downpipes it sounds like twins would be best suited for you, unless you get rid of the AC and put solid motor mounts on it then you can get a 5" pipe to the back.

If you want to go with the twin T70 idea, you may want to look into twin Master power T70's (.96 A/r tang housings). They cost ~600 a piece. Pureveil made 700rwhp with a single rear mount MP T70 on pump gas @ 14psi. I dont see why 1200rwhp isnt achievable with those. Those should fairly quick.
If your shooting for 160# range though, then perhaps even T76's are a bit small...tough decisions. Do you think 160# is realistic while still having it spool before 5500rpm?
One could argue both sides here.
