Question wanting to upgrade to really hot turbo

Hi,
I'm new to the forumand I just bought a 90 reg cab 4x4 ctd 5sp with 208k. The pumps turned up roughly 25 percent I was told. I've located a Garrett turbo out of a 350 big cam cummins. I would like to pull the truck and do half decently. What do you guys think about me putting that size of a turbo into the truck.Any imput would be great.thanks

welcome to the site i thnk a turbo that big would be extremely laggy as a single but it would make a good twin if you had enough fuel

Yup I gotta agree with these guys, enough fuel and a shot of nitrous and you could have yourself an awesome pulling rig. However, if you want to run it on the street, you'll need twins or you will get really hot, and definitely WON'T be able to tow with a turbo that big and the amount of fuel you need to spool it.
You might want to consider a smaller exhaust housing on your stock turbo, and using it and the big one for twins. Just a thought.

The Big Cam II motors and the early Big Cam III motors have a Garrett GT 46 turbo, and the later Big Cam III motors have an HT3B. This turbo compared to today's standards is old technology, it was the first turbo used in conjunction with the pulse manifolds. Running that turbo as a single with a VE44 is out of the question if you plan on daily driving the truck. You could use it as a bottom turbo in a twin setup, but unless it is very cheap I would opt for a newer style HT3B instead. You are going to need alot of extra fuel to run a turbo even 1 frame size larger, and your Getrag is going to hate you for it.

I'd say an HX40, would would do pretty well with that VE pump, and A set of POD injectors. or something, and turn your pump up a bit more. Um Rip at sourceautomotive.biz sells injectors for your truck, I don't know if there is a bigger Bosch injector for it or not, I believe there is, anyways, shoot an Email over to Scott Goff @ [email protected], he has really good prices on bosch injectors for the other 12valves, and the 24valves as well. See what he says. Hope this helps.

Well if you did a cut pin, AFC mod, governor spring, POD's, and adjusted the fuel screw to different fuel stops you may get around 400hp out of it. I would recommend an S300G, better than an HX40 for under $700. Call Harry at www.piersdiesel.com and ask him about the POD's and the governor spring, he won't do you wrong. Sorry I just noticed it's non-intercooled, you may get around 350hp to the wheels with the before mentioned setup. But I would look into modifiying your H1C, or an HX35 with a Schwitzer 60mm 6 blade compressor wheel, and running a 16cm or an 18cm exhaust housing instead of the S300G, it would be a little overkill.

Thanks

I like the idea about the 16 cm or 18cm housing and the 60 mm compressor blade.Could i put a 66mm compressor blade in a stock hx35 housing? I checked on prices on the housing and wheel on ebay and thats very affordable. Thanks alot for everyones help I really appriciate it.

The 62, 64, and 66mm compressor wheels are used in a hybrid form of an S300G, they will not fit the HX35 cartridge. With the right power your truck will not have a hard time spooling either a 16cm or an 18cm exhaust housing.
