Nope, no turbo here. At 2000 bucks I don't find the dollars/enjoyment ratio to be there where I'd want it to be. I run the thing less then 150 miles a year, and there are no hills to worry about.

I thought about flipping the manifolds around and running a custom pipe above the engine between the two banks and running an hx35 that I have on it. But once again, the cost and effort still wouldn't be worth it as far as I'm concerned.

I did a lot of research though on it so I can answer some questions if you have any specific ones.

I'd try to use the exhaust manifolds off your truck engine for your setup to work easier. Otherwise you'll have to custom fabricate the up pipes to the turbo. You'll have to see how they will work with the bus firewall though.

I'd save the money on the electric fans. I doubt you'll see a benefit. I'd run what you have as far as radiators. Mine seems sized fairly large from the factory. Get the gauges setup and watch how hot you run and upgrade if necessary.

FYI
@booyah
Ended up cancelling my order with banks engineering. While I know them to have a great reputation and would prefer a product with their name on it, I'm opting for this kit:

http://www.gohypermax.com/ProductDis...e-81f189b5d8e9


It is made to install without any issues in an s1700.
I hear you you, if I didn't have no less than three cross country journeys planned this year maybe it wouldn't be a priority for me either haha. As it is I'd like he extra go power. If you ever do feel like biting the bullet it does seem
Like hypermax is the most simple to
Install.

Hell they didn't have that kit for the s-series internationals the last time I was looking. That should be exactly what you need.

A turbo on yours will make the engine a night and day difference. Add in your new manual trans and you should have a real hot rod. Hopefully your zf5 and the brownie will work well for you.

I agree with you on the hypermax you got. At the time I was looking(2+years ago) I thought that all the kits available would have required too much modification/fabrication for what I was paying. Now I'm not saying the banks or any other stuff is junk, most of it is pretty good. But if I have to fab/hack most of the kit to make it work, I might as well just fab it all, because I'm sure I could have saved money on it.

Let us know how it all works out!

Turbo installed flawlessly here is an update on the journey of the machine for those interested.

Underlying moisture from a leaky window over the winter has led me to rip up my hardwood floors. Geez what a but load of useless weight. Innever really liked the floor anyway so I'm taking it as an opportunity. I will be adding a rubber layer for sound dampening and then insulation and plywood.
I've had a local shop totally overhaul my engine, they can do a better job than I ever could, they have better tools and knowledge etc.
I'm installing a spicer 5756-b transmission instead of the Allison auto. It's a five speed direct With granny first. I will have 15 forward speeds.
It's taken a lot of reading and crawling under the bus, but I have determined it doable.
I've always wanted to drive a twin stick rig, so I'm building one. Any questions? Hahah

No questions but I'll sell you a B model Mack with a 5&4 with a 4 spd brownie. That will give you.....ummm......80 forward, if I did the math right. A gear for any season!

I'm so jealous of whatever life you live to casually have a truck like that. What year is it?

Not mine, a friend's. We're both B model Mack people, he's just thinning out his herd.
These are what I learned to drive on and drive for a lot of years.
