Turbo time!!!
So.......... The turbo sat there, staring at me for weeks, I contemplated a complete head tear down prior to the install but this rig runs so sweet, has such low miles and the thought of removing the head and breaking the seal on the head gasket made me uncomfortable.
On the Denco setup, you pull off one of the lifter inspection covers and weld on the oil return tube. The Denco gets the dimensions correct as the oil drain is over 3 times the size of the supply line, allowing the oil to drain quickly.
Once that was done, I installed the supply line. To do this, you remove the EDIC control box, use a 14mm to remove the oil pressure sending unit, apply some yellow Teflon to the threads and install the T. The braided supply line runs over to the turbo.
I placed the line in a clear plastic cup, wired the fuel lever to OFF and cranked the engine until I had oil to the line and into the cup. I did this to clear the line and verify oil pressure (which was significant even at cranking speed).
I decided to run a Moroso Catch can on the PCV system. I did this for a couple of reasons. One reason is to monitor how much oil I push through, which I think helps monitor blow by and second, because oil in the combustion affects Cetane. I had to use a 5/8-1/2mnpt 90 degree fitting as Mr. Toyota decided that that HUGE line size was needed for this little diesel. I had to special order the fittings and NAPA was the only place that had 5/8 line rated for fuel and oil.
I previously installed Isspro EGT and Boost gauges with 24V bulbs on the top of the dash. I removed the dash and drilled straight through the severely dry rotted and cracked dash. I'm happy with the gauge location.
The first drive was a disappointment, LOW boost and low power. I went home and realized that I had not capped off the 5/8 port on the side of the throttle, that makes for a significant power drop lol. So, I capped that off and went back out, big improvement (only about 7 PSI though) and REALLY low EGT's. I went back, increased fueling by two turns and made a full turn in on the waste gate actuator. The result was black smoke off boost and 9 psi with no smoke and 800F (post turbo) EGT's uphill, under load.
Now, it feels quite snappy, and actually accelerates up hill lol. I can't wait to feel it with the regear.
