Turbo Guru's, T3 question(s). Please advise

[A to Z]

Turbo guru's please read:

I have the T3 Turboboosts M12 turbocharger I got off of eBay, and because of what I have learned on here and other pages....being a draw through setup with crown manifolds, etc., I have sent the turbo off to "G POP Shop" in Arkansas to gee carbon seals installed, and the hot side is getting their high temp coating in Titanium finish, and I am having the compressor side powder coated in gold. Since it is there, I am thinking about possibly having a custom hot side wheel put in to create a faster spool. It has journal bearings, which doesn't bother me as this is just a weekend around town toy.

The Specifics of the turbo are:

Compressor : Inducer 52.7mm, exducer (outer diamter) 76

Ex turbine: exducer 55.8mm, Inducer ( outer diameter) 64.8

Trim: 48.1

A/R .50

420 HP Rated.

Going on to a 171 cubic inch (2859cc) inline six cylinder

Any opinions on exhaust wheel sizes, etc., that will help deal with a 4000 RPM spool, outside of manifold work and larger down pipe enlarging etc. I am thinking custom wheel(s). Not sure if porting would help either.

P.S. I was shocked to find out Garrett turbos are made in Shanghai, CHINA.

That looks like a stage 3 turbine which is good for street.  You need a .63 A/R turbine housing - your spool will be somewhere around 3100 rpm.

thanks.  It is at G Pop Shop.  Getting Carbon Seals installed, and a possible port and wheel change for quicker spool.  My redline is 5500-6000 RPM, so I am willing to sacrifice a top end I won't use for more "meat" in the mid range.
