Hey guys, new here. Have some mild turbo experience in the past but pretty limited so I kinda want to start from scratch here.

What is all available for SB turbo systems? I'm aware of the Banks twin setup, is there any single turbo setup's for SB motors? What's a basic rundown about what is involved with a single turbo? Fuel injection systems... do you need them or do these feed into carbs? Kit prices?? What all is needed to be upgraded in a motor for using these or can you buy crate motors pretty much setup with the right componants to run a turbo on mild boost?

Thanks
Buddy P

The big problem in finding a kit, is one that will fit under the hood. I guess you could run an STS, but after installing the Banks kit, I just don't see how it could be any easier. Not much fab work needed at all.

You could do a blow through carb setup, there's a member here that's doing a single with blow through. :yes:

As for the motor, at a bare minimum, you should keep the CR 9.0:1 or lower, forged pistons and a boost specific cam.

These are just my opinions, results may vary. :D What are your goals?

Honestly, I don't have a set goal in mind. In the process of actually starting a restoration right now. Just wanted to plan ahead and figure out what I wanted to do. Right now I had just planned on a Crate 383... but turbo's are pretty cool! Didn't know if it is something that could be somewhat easily upgraded on a motor down the road, which leads to my questioning internal motor componants.

Kits are hard to find, for sure, and I haven't seen any single-turbo one's at all.

I bought a set of Kook's headers and made little intermediate "wastegate boxes" to locate the turbos better and give a platform for the wastegates. Besides the headers, I designed, and my cousin welded, everything else.

I'm also using a blow-through carb from CarbShop and it seems okay, although I haven't really gotten into FINE tuning it yet. I'm sure that's when the head-scratching starts. EFI would be the way to go but the better stuff is still pretty expensive. Although the carb wasn't cheap it's still less than a quarter of what the EFI would cost.

I built pretty good internals for mine as insurance. Hopefully it will all stay together. I have 220cc heads and 8.1:1 compression, which wouldnt make any since in a non-boosted car. If I had built it like that thinking "maybe I'll do turbos later", the car wouldnt have made any power until I boosted it. So the combo was built around the turbos.

Good luck with the new project.
