Opinions on PTE 3227e

[LRS95TSI]

i have the option of buying a low mileage pte 3227e from a friend. i'm familiar with the 5031 but not so much with this turbo. so i was hoping for some opinions and characteristics of this turbo.

i do have a small problem, one of the holes in the exh housing is stripped and another one has been drilled and tapped terribly. i'm wondering whether it's salvageable and how, or if i should go through PTE for 229 and get a new one.

here are pictures for reference:

I know all about this turbo. its characteristics are actually pretty nice for a PTE/Garrett. They are a tinsy bit larger than a large 16G, and can flow quite a bit, and is good up to about 350whp. The turbine wheel may keep you a bit limited, but again, the combination for a DSM is rather nice with this turbo.

now im confused.

you say this is a bit larger then a 16g, isn't this turbo a bit larger then the 5031 (aka 50 trim)?

it says it supports more horsepower.

a 16g supports 350whp, this turbo surely out performs that.

I looked on pte website and it says its good for 480hp. The compressor wheel specs are Inducer-2.170 exducer-2.950 turbine inducer-2.559 exducer 2.121 hope that helps. Also it was calling it a 54trim.

yea i looked at those. i don't necessarily have a total understanding of the numbers meaning, but i did compare them with the 5031 and the 3231 to get an idea.

i think right now i'm looking at having two of the holes filled in and then re tapped for the turbo to mani bolts.

ARe you talking about Trim?

Trim is just a ratio.

Trim = ((minor wheel diameter^2)/(major wheel diameter^2))x100

compressor: minor diameter = inducer diameter
major diameter = exducer diameter
turbine: minor diameter = exducer diameter
major diamter = inducer diameter

Generally the larger trim a wheel has the more it can flow. For compressor wheels I believe that the larger the tirm, the less efficient the wheel is as well.

Hope that helps.
