3406E replacement turbo

Why do they modify the housing? Holset has OEM housings for larger wheels.

 

I like they website because they don't give any stupid names to their turbos like Stage this or that or Big Boss but gives wheel sizes, a/r numbers etc. I want to know what I am buying.

 

PP doesn't modify the housings on the Holset, but to make a MT stage 5 you do need to.

The Stage 3 is good for a stock engines with fuel codes and a hot program in the ECM.

 

What is MT stage 5?

Bigger than this? It has original BW housings.

probably get booted for posting the link, but so be it. Not selling anything, just spreading some good info....hope it helps someone.

 

MT is Michigan Turbo and their Stage 5 is machined to fit a larger compressor wheel in the housing.

The specs on the turbo in the link are very similar to my competition turbo

 

Thought id ask if anyone would like to see some pics of a holset coversion and the way it fits on motor, compaired to stock? maybe help someone to decide if its for them or not ... If not, no prob ill go away quitely

 

Ok. So they are just fitting a larger compressor wheel with stock exhaust wheel? No wonder they blow with high HP, so called hybrids are only for gasoline engines because they have less exhaust volume.
