Turbo A/R 1.51?

[95.12v.Cummins]

What do you all think of this turbo
Compressor: 61.5mm inducer,87.4mm exducer
Turbine: 79.9 mm inducer, 70.8mm exducer
Housing A/R: Compressor: .55, with 4.0" hose-type inlet, and 3.0" hose-type discharge
Turbine : 1.51, with 'T04' type turbine inlet flange, and quick-release v-band discharge

what worries me is the A/R of the Turbine housing. Any opinions on this set up at about 450-500hp truck thats a DD and occassonal tow rig?? any ideas on what a quickspool turbine houses A/R is?

Thanks in advance!

For a comparison, a lot of S300's have a 0.80 A/R housing on the same size turbine. I don't think that would be a good option at all.

S300's did come with a 1.51 turbine. If the turbo is cheap the buy it and upgrade it to a smaller sized housing. If I recall correctly most performance t3's use a .83 but they are not cheap due to the built in waste gate and it will be a bolt on. I prefer t4's for the cost and flow but it won't be a bolt on but it is not hard to modify to work. Forced inductions, htt, Ed, bulls eye are a few to get ya started on finding a new one.
