I had to machine up some custom fittings for the turbo inlet and outlets to fir the silicone piping.
The inlet runs 76mm from the air box and then reduces down to 50mm on the inlet.
The outlet runs 47mm on the housing through a custom tapered fitting straight to 76mm...ok, yes, I know the sudden size difference might cause a bit of lag because of the pressure difference, but I don't have enough space to step it up two size increments before going 76mm :rolleyes:

I clocked the turbo while mock mounted on the manifold and I had to put a fair bit of offset in the wastegate actuator arm, but it works :lol:

Nicely done !!!

Suggestion... if still possible. If there is enough meat on the wall thickness of the reducer fitting, try machine a small lip on both ends to allow the silicone hose to still slide over but once there is a clamp on, it will seat better to prevent the hose from blowing off under high boost. I had it once and though I got shot..... hahaha.... made a big bang as the pipe popped off

So end of day two and the Patrol still won't let the injector pump go :banghead:
1 bolt of the rear bracket just refuses to give up the goods, so I gave it a good shot of penetrating lubricant and I'll call it a night, because the bloody stump where my hand once was hurts too much :rolling:
I graunched the hell out of my hand on ever conceivable bracket, mount and sharp edge in that engine bay :redface:

So far I can say to those who are planning a DIY conversion is be damn sure you want to fit an aneroid to the pump !
It's dik work to get the pump out !!!
I removed the vacuum pump to get to the bottom mounting bolt, removed the front cover and pulled the timing gear off the pump.
Removing the injector lines was a nightmare.
Nissan...why...why did you make it so difficult ??? But I suppose it was designed for 4' midget sized Japs to work on and not 6'5" guys with hands like frying pans :lol:

I hit an bit of a weird snag along the way.
I undid the injector lines nuts, then turned out the bolt on the support bracket that stiffens the lines so it would be easier to move the pump back.
Suddenly I started seeing a lot of liquid dripping off the block.
Checked it and it was engine coolant :think:
The bolt was on the end of the oil filter assembly.
Refitted the bolt and it stopped.

Haha.... I recall when I rebuilt my motor, there was the one bolt between the block and the IP that was a pain to get at, but if I recall removing the vacuum pump made it easier.... was a long time ago, but my hands also still start hurting at the thought of that day.... :doh: :doh:

I removed my pump recently too. I feel your pain.
Michael told me he removes the pump without removing the power steering pump. My hands just don't fit in there. Getting a mirror in between the radiator fan and the balancer was another bugger....

Am I correct in my assessment that this is therefore a Dustin Datsun?
