Rob,
Unfortunately I have no info on your post, however I also have an 80 series 1HZ and would really love to put a 1HD-T in it. How much did yours cost and who did you buy it off?

Regards

Hi
Please tell us what motor you are replacing and what tranny is in there at the moment. If it is 4.5 to be replaced by 1hdt and you have auto A442 tranny (94 and earlier) then you will need the control box aswell as torque converter and flex plate.
The other option is to make it 5 speed. 95 on had a different box again, and the control for it was in the motor ecu.

Hi Rob

Was it expensive? What happen to your old motor? Where do you purchase it?

I wouldn't mind a good one too.

Thanks for the response, we live in good old Canada and the engine was imported from Japan. The engine being replaced is the 4.2 and you say the ECU is on the engine, any way to make it work on the gasser?

Thanks'

Yes it is a 4.5 gasser with auto transmission.

As for the 24 volt system, this engine is a 24 volt start and then a 12 volt run. Alternator is 12 volt which we have figured out.

Thanks again

Rob

I haven't checked the part number, but it sounds like the TPS or
Throttle Position Sensor. It usually provides feedback to the auto
tranny computer as to what the driver is doing with his foot. With
the earlier A442F's I *think* it would be controlling the OD and
torque converter clutch. Perhaps your truck doesn't have any tranny
electronics?

Is the connector green? It sounds like the temp sensor for the
glowplug ECU? Perhaps you don't have a glowplug ECU (considering the
truck started life as a petrol). Do you have a manual glowplug
switch, or are the glowplugs connected (the 1HD-T will start without
them)?

Just realised you have the 97 model. It will have the smaller tranny and will not be able to be put with the 1hdt.
You need an A442. They do come completelty hydraulic in the 90 model or electronic 92 on 80 series. There is a halleffect sensor for the tacho in the fuel pump that gives feedback to the tranny computer on engine speed, then there is temperature and whatever else.
Maybe a 5 speed would be in order?

Starting to think that myself, not sure which way to go.

I will have to contact my customer and see what they would prefer.

Thanks for all your help.
