Thanks, useful to know. I'm probably going with the rotrex C38 61 as it is compact - I have a "dummy shell" of one on loan which I am using to make my plywood bracket template, the pulleys are available between about 75 - 110mm I'm not planning on intercooling at the moment as the PSI will be...

good news - I've refilled the coolant and the cooling system seems to work. I did a different filling approach, I think last time I got a bubble on the return from the radiator, this time I filed up the return hose from the radiator manually. I will do a few short runs and after cooling will...

hi all, update - I took the radiator hose off the thermostat and there was a lot of air in that hose. So I filled that up and refilled the system, and it started to work. Since then I have changed the cam belt and fitted a new water pump, got a mate round who is a mechanic to help ensure the...

Btw - follow up question, on my ECU plugs, the unused pins (from the factory) have a yellow rubber or plastic dust boot, is it possible to obtain these? Thanks, Mat.

Hi, thanks for the info, I will do this. Yes mine is a 40/40/40 from a 92 Soarer. I was planning to put heat shrink over the end of each unused wire but now I know they can be removed I'll take them out. Mat.

Hi guys - what is the method for removing pins from ECU plugs? I left mine long enough to resplice in case I had a wiring problem and had to reconnect something. Now it is running fine and I don't need to do this I can remove he other wires from the ECU plugs. Thanks, Mat.

Thanks mr Cribbj, funnily enough that's why I want to know - just doing a "proof of concept" of fitting a supercharger. I've got a plan to make up a bracket which I've nicknamed the "squid" bracket - well we've had the fish bracket.... to mount a centrifugal charger. I'm looking for a mild...

Thanks, I've run it for about 10 minutes at a time, just idling and light revs once a bit warm. I've been too scared to let it run longer for fear of causing damage. What is worrying me id that the heat isn't getting to the heater radiator either - shouldn't that be getting hot straight away...

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...

Hi all, Thanks for the replies. Sorry forgot to finish the sentence.... I meant take the thermostat out to test it - wasn't planning on leaving it out. but I've been running it with the heater valve open and the heater fan on, and that is not getting hot. I've got a Gates cambelt kit with a...

Hi, No I ran it last night, for about 5 minutes, no heat at heater radiator or main radiator, gauge went up to 80 degrees C (nb the gauge is uncalibrated) engine felt warm on the plenum and the cam covers. It just occurred to me - my car is on ramps at the front - ie pointing upwards at the...

Actually scratch that - just looked in the garage and I put two whole 5 litre bottles in, so at least 10 litres went in. Mat.

Hi all, Finally got my build running, 1UZ into a 1979 Lotus eclat. After a very long time of fabricating, designing, building, electrical systems, and making a full custom wiring loom it started first click like a new engine. BUT - I'm having trouble with the cooling. The engine starts and...

Hi, yes I got a set of 8 iridium plugs, haven't fitted them yet. I finally got my build finished and it started first click like a new car. It's been about 7 years since the engine came out of the soarer it was in!!! I have oil in it and turned it over on the starter every couple of months, got...

Hi, thanks for the replies and the part numbers. Mat

Hi all, Does anyone have a recommendation for plugs for a 1uz from a soarer, unmodified, I think I'd prefer platinum for the longer life, but open to any suggestions from those in the know. Thanks, Mat.

Hi all, Sorry for posting it in the general section - mods please feel free to move it if it shouldn't be here, but does anyone have the wheel that the cable sits in, I have been drilling mine out to fit the larger nipple on the cable I have on my car, but it snapped when I tried to drill it...

Hi, I stopped looking for the double pulley, as I've gone for a Rotrex C38 which can run off a 6 rib belt (although they recommend 8 rib belt) and found an OEM double sided aux belt, using the location vacated by the idler pulley which used to be the hydraulic fan pulley. It has more than...

Thanks George, So I guess I shouldn't worry about not having the time circuit on the cold start injector? Cheers, Mat.

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...
