All the BS about people and marketing aside, look at the two manifolds, which would you rather have? Ignore my stupid writing in the photo, i used it to educate someone before
And the GMX(1-
turbos are only good at spooling up to 10 psi, after that the back pressure ratio goes to 2x boost ratios. Not good at all for any PERFORMANCE, which is what i stated. Also the exhaust manifold is tiny and can choke the engine at higher rpms, big problem for me the driving i do with my m1008. The TO4B is a much better choice, in my opinion. Lower backpressure is easier on the engine.
I would never buy any parts that cost more than my truck, which is why i am piecing together my turbo set up, i got a gm manifold Brand new for 50, so i will use it, i would just rather use the banks manifold.
