Hello,
I have an HZJ77 with a 1HZ that was retro fitted with a CT26 Turbo along with an injection pump out of 1HDT. I purchased this not too long ago and have been chasing a problem having to do with a lack of power even for a 1HZ along with excessive smoke. The following are the symptoms:
Idles fine, runs smooth, upon acceleration begins to smoke right away, smokes under any kind of load, turbo spools up fine and hits 10psi as it should, EGT's climb high even under mild load, upwards of 1200, with the fuel set very conservative, any lower and it wouldnt run.
What I have done so far to try to solve the problem:
Performed compression test, all cylinders registered right around 500psi
Performed oil cap test, no noticeable blow by.
Had the turbo checked out, as well as the waste gate by reputable shop
Had the entire pump and injectors rebuilt and dialed in per 1HZ specs by reputable shop.
Set the timing using dial indicator per FSM spec.
Does not burn oil, based on dip stick level
Made sure the timing marks at all three(both cam gears and crank pulley) locations were at TDC just in case any of those were installed wrong.
I've dialed down the fuel screw all the way down to where it barely had any power and it would still puff black smoke.
I know this topic has come up many times and I've read probably all the threads on the issue, I feel like I have checked all the main components.
Oh and the coolant temps seem to be excessive to, at 210F when climbing a mild grade, not sure if that is related or a separate issue.
Even drove a buddies non turbo 1HZ just to get a baseline for what it should feel like, and definitely night and day difference.
I am at a complete loss where to go from here. Could the injection pump from the 1HDT be the issue of being non compatible with the 1HZ? It feels like the pump is on a completely different schedule then everything else.
Any insight would be greatly appreciated as I am beyond frustrated.
