Is this turbo good for my car?

[93camaro_zzz]

Would this be a good turbo for my car. How does it differ from tiagos. Im wondering, dont know if I could buy it right now, but I am going to look at forced induction in the future, and this is a fairly good deal. Thanks,

It would be ok maybe even real good if I knew the value of the "P" in the P-trim of the turbine.
The T04E's come as 40 and 46, but this 57 trim would be even better,I think you would be much better off with the 46 trim.

where are you getting this "sale from"

I dont want to give that information away, until I decide to buy it or not. Sorry. ;) So the 57 trim just means a bigger turbo or what? Isnt a .87 A/R ratio mean its a pretty big turbo or what?

Oops I said
"but this 57 trim would be even better,I think you would be much better off with the 46 trim."
That made no sence, I just got off a 12 hr shift when I typed that.
The 57 trim would be the best out of all of them for you I think, the 46 trim would be best for a little smaller engine that you would want to run modert to high boost on.
Trim = the area of open "compressor blades" (surface not the dia. of the intake opening that you can see when you look at the turbo from the out side) to (divided by) the aera of the largest part of the wheel.
Trim decribes only the turbine or compresor wheel.
The A/R helps explain shape and size of the divergent diffuser, the part of the comprssor housing that takes the air from the compressor wheel and turns that high velocity off the air coming off the tips of the compressor wheel into low velocity pressurized air.
A/R decribes the size or relation of the divergent diffuser (compressor housing) or the torus (turbine housing) to the radious of the turbine or compressor wheel.

I do think that would be a good turbo for your car, I just wish I knew what the h3ll the value of the "P" in P-trim was.
For your turbine I think you would want to stay with a high 70's to 80's trim I don't think you would be most happy with a big trim turbine due to the size of your engine.
My K03's have a 46mm turbine and a .56 a/r, why the small a/r?
1 is the 91 trim of the turbine and 2 is the smaller size of the turbine and 3 there will be two of them on my car.
It will take off quick at lower speeds (the A/R at work) but not be a huge restriction at higher rpms (the big wide open trim of the turbine wheel).
Here is a reply from a nother post I made a few days a go:
a/r = Aera and radious ratio
Raito, a "/" and a ":" are all other ways to say division.
To get a/r you find the aera of the nozel ring for you turbine (the thing that directs the gas on to the turbine wheel) or the divergent diffuser (the thing that takes the high velocity air off the compressor wheel and turns it into slower moving pressureized air) of the compressor and divide it buy the radious of the turbine or compressor wheel.
The a/r #'s help you figure out how much air the turbine or compersor will move.
These standardized measurements have been aroud for a long time.
9th grade math if I rember right.
It is good for compressors and turbines.
A nother one you will here is trim like a 46 trim or a 70 trim compressor or turbine wheel.
Take the aera of the inside of the wheel and divide it buy the aera of the out side. You will never have a trim of greater than 1.
That will give you an Idea of how much air and at what pressure it will move it.
If You have a 80 trim compressor, it will move a lot of air but won't make a lot of pressure.
If you have a 46 trim it will run say 30 some psi but not nearly as much air flow as a 80 trim compressor of = size.
Hope that helps.

Thanks oil pan. I am still deciding. It looks like a nice turbo, and I know one day, Im gonna wanna do it. Sooooooo. :D Well see.
