The Cartune Company (2003) Ltd in New Zealand does 1uz and 3uz conversions / parts and wiring. We have been working on UZ Toyota V8 engines since 2004 when we did our own Hiace van to transport dirtbikes around NZ. Since then we have swapped to doing mainly just Lexus V8 work from a family owned farm hidden away in our paradise , surrounded by the NZ native bush. We sell parts and simple to follow wiring instructions for the 1uzfe engines. For enquiries email info@thecartunecompany.co.nz Take Care. Kelvin

1994 1uz Lexus ls400 with 1,100,000 miles still going strong, I believe the uz is one of only 3 v8’s ever made to be aircraft certified

Thats an impressive distance. Very cool. Yes, 1uz did get aircraft certified.

Hi Kelvin. Just changed my oil from a 10w40 to 5w50. I'm very satisfied with your recommendation on going a higher oil weight with my 1st gen 1UZ non-VVTI The engine run so much more smoother on either idle or running and I feel more power across the rev range up to redline. Never thought I'll be hyped by just changing my oil! Cheers mate! . Previous oil: Royal Purple HPS 10w-40 Current oil: Amsoil Signature Series 5w-50

If you remove the oil psi relief valve insert a shim and reassemble you can increase psi regardless of tipe of oil

Hello Kalvin, I love your channel, keep posting your the best,your the only guy for uz on internet, I have swapped 1uz vvti into my mazda rx8 ,didnt had much space in the engine bay so had to install log header pipes, installed a greddy gauge and the oil pressure was 60-70psi when cold on idle and it keep dropping as the engine gets hot to 0psi but it did go up with rpm, then I installed the manual guage to confirm it, I guess the greddy gauge was faulty, becuase on manual gauge it gives me 35psi when cold and 21psi when hot on idle kept the engine running for 15mintues, I'm running 10w-30 in my engine acording to factory spec, and the weather here in my city is around 1 in winters max and in summers it goes upto 48 which engine oil should I use, I build this car for daily driving and drifting practice, we dont get 10-50 normally available here hard to find , but we do have 5-30,10-40,20-50,or heavy oil 20-60 available here, most avialable brands here are mobil1,zic,shell,calltex,liquymolly,valovoline, kindly suggest which oil should I go for to protect my engine at best, and any other things you like to mention I'm all ears, your no¹ student

@CartuneNZ 3 года назад

Simply changing the oil is a great way of improving the oil pressure. In the race vehicles I monitor oil pressure and a 5psi difference at the end of runs indicates its time for new oil. Cheers Kelvin

@nctaurussho4664 3 года назад

15w40. Rotella is what I use in my 89 ls400 high zink value as well. Shit we change oil on semi trucks at 14k if the oil can go that long in a big diesel, definitely good for my car . But with theses newer engines being produced with vvti systems, cam phasers, thicker oil will make for lazy actuators and throw a trouble code.

@CartuneNZ 3 года назад

I do like the extra zinc oils. I've found the 10W50 penrite works fine in the VVti but you are correct , too high and the VVti gets lazy , which is definitely the case when I tried the 15W60. Lesson learnt. Cheers

@Johnnyaspec 4 года назад

That's shocking, we used to shim the pressure relief valve on Vauxhall engines to increase oil pressure a bit. But I can't remember if that effected idle pressure or just max pressure.

@CartuneNZ 4 года назад

It is shocking. Ive done plenty of different mods to relief valves on other cars over the years. The boats I work on the pressure is adjustable on the pump easily and i check the logging of oil pressure every run and suggest a change when the pressure drops a little bit. This engine has had a life before I got it but fortunately its just my test engine.

@robssm2 4 года назад

One thing that the shimming does is ensure the bypass valve seat pressure is high enough to forgo a bleedby issue. So yes it can help idle and max in that way.

Hello David. 10/40 is my normal car choice. I have a vvti swap in the fleet which again has oil pressure through the ecu, on decel it was going below where I was aiming for. It sits around 15psi idle but on decel would drop to about 10-12. Still inside spec and with a switch no one would know. I adjusted but still wasn't happy so ended up between the two at the 10-50. Most run just fine on 10-40 over here in nz conditions.

Heavier oil generally leads to higher oil pressure which causes less engine performance as its more resistance for the engine to push however Getting the correct oil for your application is important to ensure best engine protection. Cheers Kelvin

@YhAFbwts 4 года назад

While I agree these are very low oil pressures, consider this. Pressure infers flow. Pressure is easy to measure, flow less so. You will get oil pressure when pushing against a blocked line, but flow will be zero. A low pressure situation with excellent flow will deliver oil to the thirsty parts. I've seen oil testing done with clear cam covers under various conditions. Under really cold start conditions crazy high pressures are achieved but little flow to the heads.

@CartuneNZ 4 года назад

Good morning Mike. You are very correct. Understanding the relationship between pressure and flow is important and how it effects operation. Your fuel pump is an example, drop pressure there is plenty of flow. My footage for this one of the pressure changing as engine warmed up didn't work as I wanted to show that as well and more on the 3000rpm pressure when the engine internal forces require pressure (and flow) to ensure sufficient oil stays between the critical parts instead of being pushed out.

@CartuneNZ 4 года назад

Good morning David. As per the video use your oil pressure readings to select oil suitable for your use, engine condition and climate. So many people just change oil to different spec without checking. Hopefully this makes sense. Cheers Kelvin.

@CartuneNZ 4 года назад

Correct, as oil effectively leaks everywhere we need sufficient flow to supply everything and enough pressure to prevent metal to metal contact.

The plan was to give this one a tidy up when it was retired from being a test engine. It will keep going for now and if gets to rattly we might have to see how long it lasts at red line and get another from my stock pile. Race engines with this oil pressure would be coming apart. I'm pretty comfortable suggesting a race engine comes apart if I'm at all worried. Cheers Kelvin
