help picking turbo

Re: help picking turbo

You will not see much of an improvement with just a larger compressor wheel.

The exhaust needs to breath better also.

60-1 wheel and cover & at least the 9 bladed turbine wheel upgrade. That would be the minimum I would do as far as purchasing parts.

Port the wastegate hole larger also.

Re: help picking turbo

I had a similar build before i took it out. Vortec heads,412, truboost, 60's,255 turbo tweaks chip, pte 52. I would go with a turbo slightly bigger than a 52, i had a 2800 rpm stall and i had full boost before it got to the stall speed.
Somebody asked why a 60-1 isnt efficient for this set up a 60-1 is smaller than a pte44,51,and 52 if i remember correctly. With the increased flow from the vortecs it would be out of the efficieny map about 4500rpm.

A pte52 uses a 60-1 wheel. A 44 & 51 uses a clipped 60-1 wheel.
