turbo question

[5.0mustangshow]

i have a 350 crate motor i am putin in an 84 s-10. lookin to also add a turbo but have no knowledge watsoever on these. wat would be a reccomended size and would i have to change a whole lot in order to have one

I dont know but if you find out can u let me know...I got an 03 Monte Carlo (205cu in.) but I dont know what size or how to install it.

It depends on engines capabilities, desired/target sweet spot for boost, HP rating, etc. Also depends on wallet honestly. Lots of choices too many variables in a setup for a generic answer, sorry.

twin turbo = t3/t4 50 trim, .63 a/r back side. good spool and will suport 800~1000whp.

single turbo = t67 for 700~800 with great spool or gt4202 for decent spool up to 1000whp.

i personally would go with the single t67 if this is going to be a daily driven truck that you want good response and a decent amount of power. single is a easyer and is nicer to your wallet.

main thing your going to have to address is the fuel managment. carb ain't going to cut it if you want it to run decent.

i would look at autronic, fast or haltech for an ecu.

having no knowledge of turbo systems i wouldnt even attempt this build. if you have deep pockets then have someone build it for you. it will save you a lot of frustration.

ya its gonna be drivin alot but not everyday, just want somethin to have fun with

ignore the blow through haters. it'll run fine on a carb. either buy a prebuilt blow through, or make your own.

i would go with a PT76GTS or GTQ, .96 A/R on the hot side. and that will be sufficient for you to run 600-650 and have room to grow down the road.

if its a carbed motor, you wont need to change much. pick up an MSD 6BTM box, Magnaflow fuel pump to support about 40psi of fuel pressure. run a return style fuel system. 1:1 rate fuel pressure regulator. and get someone to make your piping for you and you are ready to go. i personally wouldnt take it over 450-500rwhp though, not if its a totally stock crate 350. to do it right though, expect to spend in the neighborhood of 3.5k when it is said and done.

[5.0mustangshow]

ya 450-500 is right where i want it to be at. dont want to make it to wherrre its to tempromental to have fun with and not be able to drive it and have it become a garage whore

[manifoldmike]

i wouldn't say that i'm a blow through hater, i just like a reliable car. if the car was setup for track only, that would be fine. if you need help with a cheap fuel injection project and you're a decent mechanic, you might want to look at the megasquirt. the megasquirt's original intention was to convert carborated distributor engines over to efi engines for under $1000.

i ran one for about 4 years on my daily driver.

t76 is a great turbo, but if 450~500 is all your looking to make that going to be too big. any 60's mm inducer turbo will probably be a better choice. if you go single.

either that or a gt4088 or a gt4294 if you want gt series.

pricing:

pt76 = $1500 (1100hp)
t67(to4r or to4z) = $1000 (750hp)
gt4088 = $915 (650hp)
gt4294 = $1300 (1000hp)
twin 50 trims = $1400 (1000hp)

alsro remember that when running a single, the crossover pipe and exaust is a little more tricky to fab up and keep from breaking. the bigger the sinlge the more weight being slung around ever time you hammer on it. it has to be braced pretty good. not to mention that the exhaust and the intake piping have to be larger, upping the cost of piping and making it harder to build in tighter spots.

if your did smaller turbo twin kit, with a couple of logs (which are fairly cheap), you would have your compact routing, strength and simplicity of the system. your intake tracks would be smaller and the exhaust would be smaller too, but just as effective.

if your honestly only going for 450~500whp, you might even want to try twin internal gated turbos somthing like a t3/super60(750hp) or a gt28rs(700hp). you would have great spool with good power handling without the hassle of running external wastegates.

with the PT76GTQ, a stock set of iron eagle heads, 355 flat tappet hyd. motor, you can lay down 550 at less then 10psi. and since it sounds like its going to be an automatic, i really would not be concerned with spooling that thing up. i mean hell, he could probably even get away with a Master Power T70.

i've made 500whp on 5psi on a t67 with an lt1 on a sts kit, non-intercooled. manual trans though.

[Sneakin Deacon]

ok? i guarantee it was not through a stalled non lock up automatic which is what this thing will be if they are wanting to make it fast.. sbc and LT1 heads arent the same. stock sbc heads are usually quite crappy in comparison of flow..the example i gave him was a budget build typical setup, saying 550 at less then 10psi was more for a visual that there would be alot of potential for growth later down and the turbo would still be rather efficient.

ya its gonna be an auto, but do u think twin would be just as much as the one single as far as the fabrication goes witht the pipes and whatnot

eh, may be a bit harder, you have to merge 2 intake pipes then, and if you run an external gate, you have to buy 2 wastegates, gotta run oil to 2 turbos, it can be done, but it being able to buy cheaper turbo's may quickly be negated between labor and 2x as many other certain parts
