well, we could debate 1HZ vs. 13BT for a long time. They are both better than a 2F (they don't have any pesky spark plugs). I have a 1HDFT, a 1HZ+T and had a 13BT. I like them in that order. The 1HDFT is the cat's meow. The 1HZ+T is silky smooth and quiet, is a modern overhead cam design, and has terrific power.
Work continued this weekend; Though much of my time was spent gathering more parts. I deleted the rear heater, and am using the "T" in the heater lines to supply the Disco Potato with coolant. The oil adapter for the oil sending unit is in, the oil line connected (Note: 36" line, more common, would have fit).
I was unable to actually bolt the turbo up as the adapter from Oz needs Socket Head Cap Screws (ie: allen bolts) in place of where the OEM studs hang on the 1HZ manifold, to fit in the counter-sunk holes in the adapter. I found high-strength ones at McMaster part#96144A265 (m10x1.25x40mm).
Also ordered up some metric studs:
Exhaust / Manifold Stud 8mm x 1.25 Pitch [FST-030] - $1.35 : Himni Racing, Turbocharger, Turbo, Garrett, Turbo Kit, GReddy, Mazda RX-7, HKS, Apexi, TiAL, TurboXS, TurboSmart, Flange, Turbonetics, Exhaust, Intercooler, ACT, Intake
and copper clad lock nuts:
Copper Clad Exhaust Lock Nut 8mm X 1.25 Pitch [FST-031] - $1.35 : Himni Racing, Turbocharger, Turbo, Garrett, Turbo Kit, GReddy, Mazda RX-7, HKS, Apexi, TiAL, TurboXS, TurboSmart, Flange, Turbonetics, Exhaust, Intercooler, ACT, Intake
for the back of the Disco Potato; where the 5-bolt-to-3" VBand adapter bolts.
The V-Band adapter is stainless, but my 3" exhaust is steel, so using a steel v-band on the exhaust side.
Spent some time removing the 24-volt glow plugs, only to find that they are already 12-volt.
So, then removed the IP's fuel solenoid to find it too was 12-volt. Waste of time, but sorta nice that it was already converted.
The 1HZ is missing a couple bits and pieces; the clutch/fan/pulley are missing. I have a 1FZ fan, but the clutch doesn't have enough neck height to clear the main pulley. I think if I get a 1HZ fan clutch, the 1FZ fan should bolt to it?
Anybody have a 1HZ double pulley?
How about a used 1HZ fan-clutch? (I could rebuild with new fluid)
Was also missing the PS reservoir, but was able to modify an old BJ70 one to fit in the stock location.
The eBay-special aluminum HZJ75 radiator fits ok. The quality looks ok also. I'd have ponied up for an OEM, but I need to keep the budget in mind (I think I paid $225 or so... though looks like it is already discontinued?).
Power Steering High Pressure line, looks like an 80 Series version should fit (was recently used on a 1HZ-FJ60 conversion I saw, and fit great); or I could take the two fittings I have and get a hydraulic shop to make the hose (but it'd probably only save me $15, and would cost 3 hours of my time, including the drive back and forth).
New Timing belt, water pump installed.
Picts coming. Camera is at home.
