O trim exhaust wheel? (in a T04E 57 trim)

[luizdiefenbach]

Let me explain the my situation:
I live in brazil and near my city a large company produces some turbos... ( for me its like 5X cheaper buying a turbo here than bring a turbo from the USA) the company is called "masterpower".
I wanted to put a 50 trim / stage 3 / .63 in my car but since we only have 57 trim here I think the 57 will be ok for my aplication, but I have one problem.
the problem is that the 57 trim turbo here comes with a TO4 58mm exhaust wheel (one site says this wheel is a O-trim) and I don't have a clue how this wheel behaves in a 57 trim turbo.
The configurantion of the turbo is:
.70 A/R compressor housing (4" inlet)
TO4E 57 trim compressor wheel
O-trim? exhaust wheel (73mmX 58mm T4)
T3 .63 A/R exhaust housing


So I wanted to know how this combo (.63 housing + o trim) compares with:
Stage III (T3 76 trim) + T3 .63 A/R
Stage III (T3 76 trim) + T3 .82 A/R
Stage V + T3 .63 A/R


Some data about the wheels:
Stage III exhaust wheel (T3 76 trim) = 71,00mmX61,85mm
TO4 exhaust wheel (T4 63 trim) (its the o-trim?) = 73mmX58mm
Question: what diameters Stage V exhaust wheel has?


sorry for my bad english
and any imput will be apreciated,

From my understanding, the 0-trim is the smallest t-4 turbine wheel of the old t-4 series. the progression goes like this from smalles to largest: 0 trim, p trim, q trim, etc. etc.

i am almost certain that a stage V t3 wheel is LARGER than an 0 trim t4 wheel. From what ive heard, the stave V t3 wheel is about the same size as a p trim t4 wheel.

the 57 trim compressor is generally not liked in the DSM world although it has gone fast before. the problem is you can go faster and have better or equal spoolup with other wheels. the 57 trim WILL perform for you though if set up right.

basically, if i were you, i would buy the turbo you have readily available in Brazil. With your car dialed in correclty, the turbo you mention should be good for 11's no problem. the 57 trim wheel flows better than 50 lbs/min which is easily good for 11's and low-mid 120 mph traps.

first thanks a lot for the input.

so stage III is near in size to a o trim?

what other wheels? GT wheels?
