I'm close to finishing my 1986 na2t conversion after doing it for 3 years. I'm dying to finish it but I'm unable to figure out why it runs so rich that white smoke now comes out the downpipe and gas is dripping out. This was not an issue prior to the na2t conversion, and only presented itself after I finished. I'm 99.99999% sure the white smoke is from the massively rich mixture not burning well. It's POSSIBLE something magically fried and it's burning oil now but I find that hard to believe given I didn't touch or do anything that would have caused that.

1986 300ZX NA 5spd, all donor parts came from a 1986 300zx Turbo automatic ECU, Injectors, Turbo manifold, Turbo swapped onto car. Using relocation pipe instead of crossmember swap

CHTS looked original. Replaced. With or without it plugged in the car runs the same. I'm getting Ohm readings testing directly from the ECU side of the harness.
ECU diagnostics complain about CHTS still, code 13
O2 sensor was known good before the swap. unplugging it made no difference in how it runs.
Swapping in the old NA ecu and it still runs like doodoo.
Pulling the spark plugs, 3 in a row were soaked in gas, didn't bother pulling the rest. conclusive that it's not a single injector sticking.

It would be completely drivable if it weren't for the embarrassing amount of smoking and I'm very concerned that the unburned fuel will catch my engine bay on fire (open downpipe until I can justify the cost of an exhaust system)

It drives but god is it too rich to do so without tearing up and killing 5 brain cells a second. It will be driving off a cliff if I can't defeat this.

I'm offering beer or bong hits if you want to give it a shot at my place in Bellevue, WA. Thanks for anything!

Large amounts of white smoke generally means coolant, which means blown head gasket. What's coming out your tailpipe might smell like gas, and likely has some unburnt fuel but most likely coolant/condensation plus a little gas.
