Has anyone tried to delete the air flow meter from the stanard ecu setup?
Mine started playing up so I disconnected it and the truck goes much better only problem is the check light comes on and the idle is a bit irratic.

Is there a way it can be wired so the check light goes out and the idle improves?

they should be ok, 90 and 91 models are basically the same, all depends on the plugs they use in the harness. there are a few different ones and they are unable to be plugged in at all, try the lextreme forum, a lot of times someone has a thread on ECU part numbers and plug configurations.

Why don't you go the manual route mate, you don't need to wire anything up then and the R150f gearbox is way strong enough. you just cut the auto trans part of the loom off the rest and cap the power feeds.....Too easy.

Make sure you get the fuel pump ECU if when you get your engine. I used the factory V6 fuel pump in the tank, wired it up in the kick panel near where the ECU fits and made a custom fuel line that runs from the tank to the crossmember behind across that and up the other rail and I relocated the fuel filter to the other side as well, works a treat!

Are you still using the stock v6 radiator?

Yes I am, I have modified it slightly but not much, basically I had the necks on the top and bottom swapped to the other side and made a pipe that runs up from the bottom pipe so I could attach it to the engine, I have had no overheating issues at all, the 14" fan seems to cope very well.

I have trid to fit the celisor/soarer style manifolds to my truck, the left hand one (our passenger side) fit in there no problems but the drivers side one hit the steering shaft after a weekend trying to modify it I gave up and fitted the log style manifolds, they work well and fit nicely with no mods, I am curious about the landcruiser ones as they look like a larger style log, maybe something for the future.

Hey Cebby, hows things Going with your build up? can't wait to see the finished product. Mine has been on the road for about 6 months and have not had any problems whatsoever, it the best thing I ever did. I've started a new project now, Turning a LN60 4runner into a short bed pick up ( they are very rare in Australia only 1979-1981 we had them )

hope all is going well mate

I have two questions for you; did you use the original fuel pump and fuel tank, and did you use the original radiator?

G'day Toylexus,
Yes I did use the original fuel tank and pump but I wired in the fuel pump control unit that came with the engine. this is much easier than trying to work out what signal to use to keep the circuit open relay on after startup as this was the job of the V6's flap type airflow meter. as for the radiator, it is a modified original. I moved the top and bottom necks to the oposite sides. the top one comes out of the left side and turns 90 degrees inward, the bottom one comes out at 90 degrees the same direction but has a upward tilt to it, attached to this is a small rubber hose then to a 40mm pipe that runs up the side of the radiator to a 90 degree bend pointing straight at the thermostat housing. I haven't had any overheating problems as yet but it only has been idling in the driveway and driven to the exhaust shop.

A word of advise, remove the temperature sender from the rear of the V6 ( it's the small one with one pin) and put it in the 1UZ(this one sits on the right front of the engine under the ignition lead cover), this way your gauge will read correctly as the have different resistances. I also did the same with the oil pressure switch.
