Lol the equivalent to a single 70 millimeter turbo im running a 30mm and a 40mm


~jared miller
I just couldn't let this go. A 30mm and a 40mm turbo is not the "equivalent" of a 70mm turbo. Do you realize that 30mm is approximately 1 3/16"? That wouldn't be enough for any truck. Here is a fun fact, Google 30mm turbo and you will come up with a nose cone for remote control airplanes. A search for 40mm turbo actually does come up with a turbo! It fits a mini cooper... 40mm is approximately 1 9/16 you are still smaller than a single primary tube on a standard header for a small block. I'm not a turbo evil genius but I am a car guy aware of turbo basics. I'm just saying that if you want a twin turbo system, you need to do a lot more research because you aren't going to get there on remote control airplane parts and mini cooper throw away parts.

I'm starting to believe that you haven't built a turbo system before, and are just dreaming about it for your truck. When people put turbos on they are usually atleast 70mm when single and then when they go two turbos it's usually a race machine with atleast dual 85mm

So you're gonna swap the rear end everytime you wanna do burnouts or strip or daily driving. That seems like a lot of work
