Someone locally has a Garrett T04B for sale with the following specifications:

Compressor wheel is .60 AR and exhaust side is .96 AR.
P-trim exhaust wheel in a 1.00 split pulse v band rear T4 flanged housing
.6 compressor cover with a 3" inducer

Now, I've done some research, but haven't found much information on people running this particular setup. It seems most use a v-trim exhaust wheel, which is slightly bigger (1.15 AR I think)?
I'm aiming to make anywhere over 300whp on a stock port S5 and am just trying to figure out if this is a suitable setup for it. Any opinions are appreciated!

Edit: the ad is listed as a T3/T4, is that a sizing between T3 and T4?

 

There is a good chance that the information given about the turbo is not accurate. I say it is probably not accurate because it lists a T4 1.00 divided turbine housing, then it says a .96 turbine housing (which is always undivided), and then it says a T3 turbine housing? huh?? And V trim is a compressor wheel, not an exhaust wheel. Many T04B turbos are in fact mislabeled, and are really T04E's.

The best thing to do would be to get measurements of the compressor and turbine wheels and get pictures from different angles first. With that description given by the ad, who the **** knows what that thing is?

T04E : 6 blade compressor wheel
T04B : usually 8 blade compressor wheel
60-1 and 62-1 : usually 7 blade compressor wheel

should be able too with supporting mods

 

either way a t04b will get u over 300 hp with enuff fuel as long as u have the supporting mods like fuel cool air and a way to half *** controll it . i did it using a t04b rtek1.7 720 prims. 1000 secs. 255 lph pump and stock intercooler ooh and blitz elec boost controller at around 12 psi was at like 325 ish hp

 

So you're saying this:


exhaust side is .96 AR....
The Turbo has a P trim exhaust wheel in a 1.00 split pulse v band rear T4 flanged housing.

is conflicting information? I'll have to see if it's a split T4 flanged housing to find out if it's 1.00 or 0.96 I guess?

Edit: this is the ad in question:
https://www.rx7club.com/canadian-sale-wanted-classifieds-120/fs-big-garrett-t3-t4-turbo-96ar-799539/
But you can't see the exhaust flange on it.

 

That information is wrong.

Can't be a T3/T4 if it has a P trim turbine wheel; P trim turbine wheels are T4 only.
He doesn't list the compressor, there are a lot of to4B compressor wheels, and that will make the bigger difference... He needs to take some photos.

 

Thanks to all for the ton of information! I may post some pics of the turbo later (as it is now in my hands) with measurements.
