Pshhhhttttt!
My name is Mark .
First let me say this build is not about horse power , drag racing or 1/4 mile times. Its about TQ , fuel economy and a efficient dependable motor.
I own a small company ( DNA CNC and Machine) that made 2 stroke parts a while back when I was younger. I since went to college (BS in Engineering ) and haven't made 2 stroke parts in some time. Flash forward 10 years I ended up getting a great job in the aerospace industry doing cad cam work for a subcontracting corporation off of Sikorsky helicopter.
At Home I have a beautiful shop 4 axis cnc mill , lathe knee mill 2 tig machines welding and sheetmetal area( 30 in brake roller bender) with JMR tubing ultra and pipe bender , dedicated inspection area with 6ftx6ftx1ft A surface plate.
So my 4l60E took a crap on me last year . I completely rebuilt it with a lot of extra goodies. With in 50 miles my intake manifold L31 out of my 97 GMC Yukon decided it wanted to leak . I didnt realize for a bit. It tore my bearings up.
Not being my only ride I first was going to just re-ring the motor with new bearings. Then I purchased new heads . Well I decided to build a pretty awesome towing rig that had decent fuel economy. In my mind I needed a turbo for that . Because Im always moving equipment . Ive always wanted a 5th wheel camper . And well it was a great excuse to use my equipment .
So far . Ive been buying stuff to support my plan. All forged 383 motor 8:5.1 compression Ratio with + .030 Weisco forged pistons , Scat 6in pro comp forged rods, 4340 3.750 Crankshaft , Barrett racing R.H.S.( Dart Chinese copys) 205cc heads , GT45 single ebay turbo kit thats was horrible made. 6 in lift kit from ruff country . Before I go father I know allot have said and have there arguments with Chinese parts. I personally have measured and looked for run out on both the heads and turbo kit.
The heads were machined so well I was very surprised. The turbocharger was also made with exceptional workmanship. The turbo manifold on the other hand was horrible warped. With holes not properly lining up to the mating counterparts on the heads . Then to try and correct it you can clearly tell it was put on a belt grinder with the hopes of looking flat. The one of the turbo kit part that was made in the usa( in the kit) was pretty screwed up.
So far I need to buy a cam , valves , valve springs , blow off valve .
I need to make , remake re-machine the turbo manifold , Custom front mount Intercooler , intake manifold , front push bumper , flip shackles , and A arms.
Now for the pictures. Sorry for the camera its pretty old.
