Drafted my Dad to help out with the turbo upgrade today. He was able to open up the airbox connection to fit over the larger turbo opening. Put up a fight but he got it to work.
I modified the new compressor housing by using an angle grinder to polish off the outer ridge of the inlet and outlet since they would only get in the way for the O ring connections on the ATS turbo kit. It is a little tight fitting into the swirl chamber since the outlet is slightly bigger than the ATS, but I can be sure that there will be no boost leaks that way.
The compressor housing does clear the turbo pedistal without modding, but its REALLY close. I'm talking within 1/16". So close that the backing plate clamps (I think thats what they're called) have to be positioned not to be in that location. An even bigger housing would still fit but some grinding of the pedistal would be needed. The only other thing to clear will be the firewall, but I'm not worried about that. Getting it in might be a challenge though. I might have to remove the studs that hold the center section to the pedistal and replace them with bolts. There are only two of them, but they always put up a fight.
I mocked up everything on the bench and I think the swirl chamber will work even though the compressor housing diameter is larger. The outlet will simply push further into the intake hat connection and the connection has some flexibility thanks to the O ring.
After reading about possible drainback problems of the valley pan oil return, I took this opportunity to knock some holes in the baffle now while the turbo petistal was out. Used an air chisel and made a few holes in there (like butta). I wonder if it could explain the mystery oil leak that always came down the rear of the engine along with a puddle of oil on the rear of the valley pan. Find out soon enough.
Only the pedistal has been re installed as of right now. We worked steady all afternoon and ended up skipping lunch. I could have finished it, but since I'm fighting a cold, I figured I should stay in for the rest of the day. I could get even more sick or worse yet, screw up on the assembly Tomorow is another day.
Don't worry, pictures are comming.....
