Hi, I'm fitting a 1uz from a soarer into a lotus, I'm wiring in an AC relay, I have a couple of questions: I'm presuming the AC clutch is fed with 12v and it grounds through the block to activate the AC compressor - is this correct? On the 1992 sc400 wiring diagram there is a white wire that...

Hi Vince - just bumping this up in case you haven't seen it.... Have sent you a pm. Cheers, Mat.

Cool - like it!

Thanks! have sent a reply. Mat.

Hi mr Bushwhacker, I've also sent you a pm about wiring in case you haven't seen it. Thanks, Mat

by the way the oocling system is a lot like the cooling system.....:)

Hi, The pipe that is a single pipe dissappearing under the plenum is the return, the pipe that goes straight down into a merge with the bridged part is the outlet. I have a drawing of the oocling system that shows it, if you pm me with an email address I can send it to you. Having said that...

Hi, I'm fitting the 1uz from a 1992 SC400 into a different car, But I have used the PAS pump off an LS400 as i wanted the attached reservoir. The car is a Lotus, but the rack is sourced from a ford. Can anyone suggest a UK available power steering fluid for this application? Or what to avoid...

Hi - I'm interested by this - please can someone give me an idiots guide to how to extract the obd1 data from the 1uz?

Hi, has anyone bought the EGR delete kit off this site? If so did it fit ok? Can anyone let me know who the person behind selling it is and what their email address is? Thanks, Mat.

Hi all, I've got a 1uz I'm fitting to a Lotus eclat. I'm at the stage where I need to get an exhaust system made, I can't do exhaust fabrication myself so need to use an exhaust specialist to do it. So I need to tell them what I need. If anyone on here can help by suggesting design and sizes...

Thanks guys - yes the soarer my engine came out of is a jap import (no official soarer imports as far as i know) so i'm guessing the diag on here is for the USA spec one(?) Anyway thanks for the info. I got the idea fro the heated sensors from reading a thread where someone in the UK had...

By the way - the ECU wiring diagram I have got has sub O2 sensors on it - it is a PDF from this site, it's labelled as "1992 SC400" a PDF in two parts. But this diagram also shows the O2 sensors (all 4) as 4 wire, whereas the ones on my car are 1 wire. The HTv leads on my enigne say 1991, so...

Hi Beezer, Great stuff - thanks for the reply. One less thing to worry about! I'm going to try to fit universal O2 sensors with the heater connection, i've been told it works more reliably when heated, and gives better running. Cheers, Mat.

Hi all, Got a question about O2 sensors - I'm fitting a 1uz soarer engine into an old lotus. I have the soarer manifolds with the O2 sensors but not the sub O2 sensors post the CATs. My car will not have any CATs. I intend to use the primary O2 sensors in the manifold, and not use the sub...

Hi, Thanks for this post - I'm fitting a 1UZ into a Lotus, I've got the loom that supports 1 wire O2 sensors, but no o2 sensors so need t buy some. I always wondered why some are 1 wire and some have 3 or 4. Am I right in understanding what you're saying, that the three wire ones are two...

Hi, Thanks mr Gloverman - that's really useful. Mine is definitely the round connector with three blades on the alternator, one perpendicular to the other two. Do you happen to know a part number for this? Or what I should ask for at the Toyota parts shop? Normally anything I ask for on ths...

Hi all, I'm missing the plug that goes on the back of the alternator on my 1992 SC400 sourced 1uz. Does anyone know what the plug should look like? Or where I can get one? Does it come from the engine loom or wiring on the car body? I can provide a photo of my alterantor if needed. Any...

Hi all, Thanks for all the replies - btw Samsdad - how did you find the Castrol Syntrax gearbox oil - reason for asking is I can't find VMX80 listed here (I'm in the UK). Was the syntrax any good? Cheers, Mat.

Thanks! It will have to be the greasy finger then..... :) Need to get the new engine number on the V5 at some point. Cheers, Mat.
