    Interchangeable 1UZ Wiring Harness

    If the part number is the same, then yes. If the part number is different, you will likely need to modify it

    1UZ into E36

    Catch can frame and internals have been tacked up and test fitted. Should have it painted and installed shortly. Next comes the exhaust.

    Catch Can Theory

    In prep to build a catch can setup, I've been weighing up the pros and cons of commercially available units and most of them are crap. Either the flow well and catch nothing, or they catch lots and restrict the air. One thing that stands out is that gas flow against a surface that opposes...

    1UZ into E36

    I forgot to note, aluminium thickness next to the spark plug tubes is only about 8-10mm and I don't have bottoming taps - so I drilled right through, and the bolts have ultra-grey sealant on them to ensure nothing leaks out + the bolt stays put. All the other bolts have Toyota thread locker...

    1UZ into E36

    Amongst many other small (but necessary) jobs, the rocker covers came off in prep for the breather system mods. The baffle plate "rivets" are removed easily with a drill and die grinder. Had the covers and baffles soaking in an alkaline degreaser for a few hours and all the oil residue came off...

    3uz low idle in gear

    From factory 1UZs have a switching valve on the power steering line so that when the hydraulic pressure goes up, it creates an air leak past the throttle and idles up then engine. Common toyota thing. Fit the valve, along with the hoses (goes into the front of the manifold from memory) and your...

    Where do those pins go?

    Thats the vacuum switching valve for evap but all the wiring diagrams I have list the trigger wire as white... not brown. Your image shows a very light brown, and the brown wires are usually a lot darker. It's possible that it's actually a white wire that is stained from age/heat/etc (?). The...

    1UZ into E36

    Oh, the joys of an engine conversion. Its the hundreds of tiny jobs (that nobody sees) that need to be done otherwise the whole thing falls apart in a screaming mess. Like today... all of it. When the shifter was installed months ago, it encroached on the area where the climate control ECU...

    1UZ into E36

    With a basic tune, rich mixtures and very conservative timing, it feels very strong. Datalog of today's testing shows boost topping out at 6psi (gate spring). The highest TPS was 45%. I can't wait to see what 100% throttle and 14psi feels like!

    AC problems from 3uz to e46

    The AC input to your ECU will be a signal from the A/C control module to indicate the air conditioning has been switched on/off. The ACMG provides ground to trigger the relay that switches on your compressor clutch and monitors the voltage to confirm the compressor is engaged. This process of...

    1UZ - A340f stopped shifting in drive

    1. Yes, that's what I would try too. 2. Sounds OK 3&4. Sounds OK 5. The test from #1 would either isolate it as a fault, or confirm it as a possible cause. 6. NSW and STA are for starting only - you should also have position inputs from each shifter position back to the ECU (i.e. PRD2L) 7. Are...
