A to Z Posted Monday at 10:55 PM Share Posted Monday at 10:55 PM 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. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted yesterday at 02:25 AM Share Posted yesterday at 02:25 AM 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. Quote Link to comment Share on other sites More sharing options...
