    Oil level sender on 1UZFE

    Hi all, I've got a 1UZ from a 1992 Soarer, it has a sender for low oil level. When the car was not running and had no oil in it, I took it off and checked it by moving the arm up and down. It opened and closed the circuit as it should. But now it is installed on the car the light is stuck on...

    cooling system questions

    Hi all, I've got a pressure cap on my 1UZ, but the nature of the car is such that the pressure cap is not the highest point in the system. It is topologically where it was on the original soarer, but as the bonnet is very low, it is low down. So I have a separate filler cap on the heater...

    Cover panel between rear of block and bellhousing / autobox?

    Hi all, I've got a 1uz (rear sump version from a Soarer) with a Bullet bellhousing connected to a W58. I'm left with a large air gap at the bottom of the bellhousing where rain / dirt / stones kicked up off the road etc can enter the bellhousing. When I bought the engine it didn't have a...

    sealing vacuum outlets - question for Gloverman

    Hi Kelvin, I saw your video on removing unnecessary vacuum lines from the 1uz. This video: Thanks for posting it up, it was very useful. I have removed my VSV and the solid vacuum lines off the plenum. I've got a question, in the video you say "I'll do something better for sealing up the...

    Broken/dead 1UZ Soarer 40:40:40 ECU wanted

    Hi all, I’ve got a 1970s Lotus with a 1UZ, it is stock at the moment, with manual gearbox but I’ve got a long term plan to fit a Rotrex centrifugal supercharger for mild boost – 5 to 8 psi probably. I’m limited by having a W58 gearbox among other things. One of the elements to figure out is...

    questions about fitting a centrifugal supercharger

    1uz fan idler bracket failure

    Hi all, I have fitted a 1uz into an old Lotus. It is from a soarer as I needed a rear sump. It came with the hydraulic fan pump, i took this bracket off and got a bracket off ebay (2uz I think - it was a couple of years ago!) which is a bracket with a pulley that just runs in a bearing. The...

    Grounding 1UZ ECU casing in a fibreglass car

    Hi all, I've fitted a 1UZ to a Lotus, it is running, but the ECU is not bolted in yet, just sitting on the floor of the passenger footwell. I was planning on mounting it at the end of the passenger footwell, using rubber shockmount fittings, and install a cut down version of the plastic cover...

    oil level sender questions (1uz from 1992 soarer)

    Hi all, @Mods - If this is in the wrong section please move it and apologies. Does anyone know how the oil level sender works on the 1UZFE? My engine is a rear sump from a 1992 Soarer if it makes any difference. From googling I’ve found a few documents and images, but haven’t got a clear...

    Preventing PAS leaking fluid onto alternator - options?

    Hi all, I’ve read in a few places about a problem with the 1UZ where the PAS pump leaks and stuffs up the alternator. My pump shows no sign of leaking but I was thinking – has anyone made a solution to this? I was thinking of some sort of bracket to shield the alternator from hydraulic fluid...

    crank pulley diameter

    Hi all, Does anyone on here know the diameter of the crank pulley on a stock 1UZ ? (the pulley for the accessories belt - not the cambelt pulley) I'd be really grateful to know. I haven't got an easy way of measuring it, as my calipers are too small. Other than a rough and ready string round...

    STA start relay feed to ECU

    Hi all, Sorry to bombard the forum with wiring questions - but I've been going through my loom, figuring out what does what, against the lextreme diagram I've got, and the toyota diagram that I found somewhere. My 1uz has the cold start injector, it is a 1992 soarer engine, with 40/40/40 plugs...

    Diagnostic plug - any need to keep it?

    Hi all, I'm wiring a 1uz, I've got the loom off the car and going through it with the diagram it all checks out. However there are a few connections that are not on any diagrams I've seen - the engine is off a 1992 soarer, the 40/40/40 plug type of ECU. There are about 5 wires I can't locate...

    oil pressure gauge wiring

    Hi all, I want to wire the oil pressure gauge on my 1uz. I've got the stock pressure sender, but a VDO oil pressure gauge I'd like to use (or I will use any other if there is a known one that will work accurately). How do I work out what gauge to get? Do they have a standard for volts vs psi...

    Hi all, I'm building up my intake, and have got a silicone hose to go from the MAF body to the throttle body inlet. I had planned to fit a sealed 16mm take off to connect to the idle speed control. But looking at the MAF body, there is a shaped section on the side, low down on the side facing...

    Crank pulley mounted supercharger

    Hi, Has anyone on here ever mounted a centrifugal supercharger off a separate belt driven from an additional pulley in front of the existing crank pulley? ie using a separate shorter belt and not the existing aux belt. On the car I've got there is tons of room in that area in front of the...
