I've had this recurring idea of a 1.9 turbo motor with some of the flaws of the past one fixed. I'd been thinking of keeping it quiet until I just said here it is but I have too many questions I don't know the answers to for that.
The first concept is the exhaust and I've tried to put it on paper with little to no success so I'll describe it. Using a blank flange from Bob (thanks for doing them ) on the 1 and 4 ports use a weldable fitting 45 to point both down and towards the center of the motor. From there a short piece of tube and another 45 to roll it straight towards the center of the motor. Another piece of tubing and then 90 it straight up so the two are joined up. For the center two use a 90 off the flange and make a loop going down to put all 4 in a 2x2 configuration pointing up and joined together. Top this off with a plate cut to fit a turbo exhaust inlet flange. The flange would be roughly 4 inches out from the head and be in the exact center and at about bottom of the head ports for height. This is all to keep the lag to an absolute minimum and not have plumbing that requires the removal of other things to get too. It would all stay above the motor mounts and come out in 1 piece.
I have been looking at the injection but to me that's a new can of worms I've never done before. Placement of the turbo looks like it will suit whichever way I go as far as a suck or blow system. so I need to look at this more carefully before I start welding or buying more parts.
I did some looking today and found a Volvo turbocharger from a 86 740 for 150 bucks that has the wastegate on it already. weldable fitting my cost are about 4.25 each so that is looking good and they have good stock too.
questions so far are the flange for the turbo inlet on the exhaust side 3/8 ok or need to go 1/2?
How critical are the lengths of the runners for the exhaust and are they measured at center line to give equal lengths?
Any comments on the Volvo turbo?
Can I make an injection intake for the motor?
Sorry very long winded but I've been holding it in.
