      I flipped the driver side manifold so i can run a pipe under the bellhousing to Y with the outlet of the drivers side manifold there is where the turbo will be placed. Plan is low boost no more than 5 psi on a draw thru design with the recurculating bypass.
      [​IMG]
      i had built a temp down pipe to get the truck around during the build
      [​IMG]
      runs good no leak from the manifold and today i pulled a garret T3 out of the wrecking yard for a few bucks

      I have some digital photos for better quality ill download those when i get a chance

      I built a flange for the turbo last night it still needs a little porting that ill do tonight on break. I did some moving on resivoirs and deleted the ac compressor for more room. Then started mocking up where the turbo will sit.

      got the cold side outlet done heres a few pics and the exhaust is done except for connecting the passenger side manifold under the motor to the flange.
      and a pic of the down pipe and the muffler is already in place minus the turndown outlets. once i get the exhaust complete ill have the oil lines to do, maf to turbo pipe and filter, vaccum lines, injectors pump and tuning.

      No intercooler then...... Build a simple water injection system...... Wouldn't cost much. I saw a nice description somewhere, I'll make sure to find it for you. You will be surprised on how simple it is.....

      im enjoying it i still have some work to do. the bov is venting to atmoshpere (at idle the bov is closed) unitl i build a reculculating bypass and it stumbles after a blowoff if im not on the throttle quick enough but its doing pretty good for not even being tuned. Soon a bigger pump will be ordered and a dyno tune. I may just stick with the 19#ers they should be suffficient if not i have 30#ers laying around. oh and the torque feels so much better. 5 psi is available in most gears from a cruise at 2k. i have pushed it past 5 a few times one of those times it did ping at around7-8 before i lifted now im watching the gauge like a hawk and not letting it pass 5psi. Tommorrow its getting new plugs and some adjustments. I still need an O2 extension to plug in the O2 sensor(im running open loop right now)

      I drove mine down the road today and I almost had a heart attack with the BOV went off. I thought I blew coupler or something and I wasn't even half throttle.

      Sounds good and props to you.

      I blew a coupler off on mine during my first WOT pull when James came down to tune it. So there I was laying under my truck on the side of a busy highway putting it back on...

      I actually have a silencer on my BOV because it is sooo loud.
