Thank you for your patience everyone! At long last, the Rajay turbo is installed! As usual, it did not go quite as smoothly as planned, but nevertheless, it went quite well. I was pretty exasperated at times, mostly over little stuff like oil lines, but I had a good friend there for mental support. The whole process took about four days.
The little "J" pipe turned out to be a perfect fit to the LD28 manifold after all...no mods necessary. What came about was that the whole setup was 2" too high to fit into the Z when bolted to the LD28. Perhaps it is the hieght of the block. So with much cursing and grinding, I fashioned a 2" exhaust coupler to drop the turbo setup down, where it fit perfectly on both car and engine. I mean, I probably invented several new curse word combinations doing this.
Below are photos of the whole shebang. I will have a video on youtube in a few weeks hopefully, to better show off what it's like. In short: much more smooth and quiet, much faster especially on the highway...it seems to accellerate even faster as you gain speed, i.e., it accellerates faster at 70 than at 30 mph, or it feels like it. Very, very easily blasts right past 100 mph at 7 lbs of boost. Cruising at 80, she holds about 1-2 lbs of boost. And of course, the sound it makes has people flipping their wigs, including me.
The J pipe....most important piece.
The major artifacts of the turbo system. I had to make all the gaskets, which was not fun, but they all sealed just fine. The little stuff was annoying, requiring many trips to Home Depot racing, aka, the bolt and plumbing isles.
The coupler. It basically just connects the J pipe to the manifold with 1.75" exhaust pipes, as shown below. It is exactly 2" thick.
Above is the complete assembly, which was bolted to the block as one piece, shown below.
...And here it is, installed and driveable. Please note that the blow-off valve on the intake pipes was removed because it didn't do anything. Also, the pcv tube was disconnected from the intake manifold, as it interfered with the turbo's oil drain system, causing oil to flow out of the exhaust pipe. This was because of the pressure the turbo put into the block, causing backpressure on the drain system. TurboMaster Pius told me to plug the intake manifold and vent the pcv to the ground with a tube, as these diesels must have a completely unrestricted oil drain system to use turbochargers. This cured the oil-in-the-exhaust problem immediately.
Yes, yes, yes, I'm on the lookout for an intercooler; the piping has already been acquired. No, I did not install a pyrometer yet, as Texas (where the project was completed) doesn't even seem to have an Ace hardware, let alone a damn pyro guage. But I have not touched the smoke screw, so all should be well. Amazingly,even without changing the fuel settings, the engine can hold 7 pounds of boost.
Thanks for your interest, and without ya'll on this forum, the diesel swap would have likely never happened at all. One final note: TURBO YOUR LD28!!!!!
