I just knew that they put out close HP to my 6.2L NA diesel did, but with more TQ because of the turbo. Mine is just bigger and overall weaker...more for cruising than heavy hauling.

My plans for power are a compound turbo setup... hx30w/hx35, fuel pin, injectors, and pump tuning should get me close to what I want if not right at it... shooting for 500ish lb. ft to the pavement... which is only 250whp or so if tuned properly
We'll see... numbers are just numbers... in stock form, it pulled the truck just fine so it can only get better as power goes up.

Its a VE rotary pump.. I wish it was a P-Pump but I'm not complaining... it'll keep up with the fuel demands of my power goals easily.
There was a member on 4btswaps who custom builds VE pumps... his last test run on the dyno surpassed 400whp on fuel alone.. he never said what he did to his pumps but it was impressive.

Update...
Trans is done... ready to install... 60e is on the ground and the t-case is done (32 spline input, MA Billet Pump, Updated rear output bearing) and ready to go back in... hoping to get the trans under the truck and start fabbing the new crossmember tomorrow after work.
Here are a few pics...
Pump..
Valvebody done...
Plugged pressure relief from previous transgo install (using sonnax self regulating valve)
VB back on with new harness, solenoids, filter extension tube and filter mount
Ready to go..
New t-case adapter and -AN fittings
T-Case ready to come apart..
32 spline input ready to go
MA Billet pump update
Rear output bearing update
T-case is back together, sealed up and ready to install. Hopefully I make decent progress on it tomorrow... we'll see. If all goes well, I should be able to get driveshafts done sometime this week and perhaps fire it this weekend. I'm really praying this thing doesn't scatter when I drop it in gear.
Anyways... more to come.
