I have a crappy lil t3 turbine side on my turbo now.. Changing to a t4 but need to know what trim I need.. What do it look at to see if its a p-trim or something else?

 

here r the specs
T70 TURBO CHARGER SPEC:

4" INLET OLD SIDE

2.5" V BAND HOT SIDE

WET FLOAT BEARING

DIVIDED T3 SIZE FLANGE

OIL COOLING TURBO CHARGER

COMPRESSOR WHEEL SPEC:

WHEEL: 0.70 A/R

IND SIZE: 52.76MM

EXD SIZE: 75.46MM

TRIM SIZE: 48.9

TURBINE WHEEL SPEC:

WHEEL: 0.84 A/R

IND SIZE: 57.75MM

EXD SIZE: 73.35MM

TRIM SIZE: 61.9

 

That is not a T70 turbo. They may sell it as one on ebay, but it's a CHEAP Chinese turbo with a 50 trim compress and an "o" trim turbine. (smaller then a P trim). That turbo is only good for about 400 fwhp, way to small for one of these motors.

Here are the specs on a "real" Master Power t70 turbo, good for about 750fwhp. (I've personally made 550+ at the wheels with one on my truck)



If you need a good turbo, I can help you with that.

 

What's the meaning with "P" or "Other" Trim?


Thanks.

 

It's a turbine side sizing reference they use, O, P, Q, S. The higher in the alphabet the bigger the turbine wheel.

Also, the "t" sizing is generally referring to the minor sizing of the compress wheel, like with the above charted T70, it has a 69.1mm minor size, so they call that a 70mm turbo.

The OP's turbo would be considered about a 53mm turbo.

 

Chinese turbos FTL!

I bet that T3 spools freakin' quick on that 4.8L though. Like off idle boost.

 

Gimme a price on a good legitimate turbo.. Need to just put this hunk on my lil dd honda..lol I am lookin at tryin to make 500rwhp
