1uz engine preparation - Why it's important to do it properly. 

I love your way of thinking. Preventive maintenance is so important and worth the time, 100 fold. My UCF20 has 359,754 miles on her and still purrs like a kitten.

I'm from New Zealand and this is the first time I've heard another Kiwi pronounce NZ as 'Nu Zeelind' haha, love the content

I'm stripping my motor shortly, good advice Kelvin.

These videos are awesome. It's so easy to miss something simple that will cost you huge grief. I pick up tips with every video. Thanks Kelvin

Thank you so much for putting forth your views. I wish more people thought like you. Thank you so much for making these videos and having this entire channel

Anything a 1 uz is planted in to especially the first generations 1uz and my god you turbo it, anything that engine goes in is magic and the engine It’s self is amazing so easy to look after compared to an equivalent German engine and it’s build quality is in a league of its own everything from the deck design to the bracing girdles inspired from jgtc where this engine was originally intended for

I need to buy one of these 1uz

This was gold, and sums up exactly my thoughts when people swap engines and don't check them over, or claim an engine is good or bad based on the stock rods/pistons capability. If you are putting any engine into a project just open the damn thing up and make sure its healthy! People often spend thousands on an engine swap and skimp on the most important bits >_< A mate swapped an engine into his car, got it dynoed and then it spun the big ends and couldn't work out why. Had he got any sort of oil pressure sensor? Of course not...

I have a 2006 Lexus SC430 with the 3UZ 4.3 V8, and I pulled apart an extra 3UZ from my parts car (very disappointed when I saw the skimpy 3UZ rods) that was unfortunately totaled 6 years ago and I am currently looking to build it up. There is someone over here that used a 2UZ block that they had re-sleeved with a Tundra crank and different rods and pistons and its displacing 5.2 liters now. I believe they used the 2UZ since its iron which makes sense. There is not much wiggle room on the 3UZ block to go oversize with the pistons, so I am looking to build up a short block as mentioned, and using 3UZ ported/polished heads with larger valves, bumpier cams, and honed intake manifold and modded throttle body. I want the engine to last since this is going to cost several thousand to do it properly with all forged internals, so Ill aim for a 4.7 if a 5.0 or 5.2 is pushing it since I am planning in the future to add a turbo with maybe 8-10lbs at the most. I am very curious what this engine will put out while NA - I am thinking it will be up from 300hp - 325lb torque to over 400hp if this is done properly and easily 500 plus with the turbo. I have the 6 speed auto which does not hold up well past 400hp, so I need to find a reputable person/shop that knows how to build up this transmission to handle the power. This car is just for enjoyment so I have other cars for daily driving, but I also need to figure out how to get past smog when I do this, which in CA can be very tough to do! In the mean time with my SC430 I am getting a tuned ECU for my SC430 here in California which makes a huge difference without even adding power and gets rid of the throttle lag, and I have a Lextreme 2800 stall converter I am installing soon with an external trans cooler, and adding headers to the mix little later this year. Apparently the converter alone allows the car to really spin the rear wheels when it was not able to when stock. I am figuring this should get me by and I can enjoy it over the next 1.5 - 2 years while building up the extra engine, taking the time to make sure everything is done properly. The current engine in the car only has 106,000 miles so its in decent shape and will hold up in the mean time. Have you worked with any stroker setups for the 1UZ, 2UZ, 3UZ engines before? There is a guy who is local that did a 5.2 but he hasnt gotten back to me to confirm all the parts he used to make it a 5.2, and he just told me it was a 2UZ block with tundra crank and he did not recall of the top of his head the rods and pistons used. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5gBmCi6WRvA.html&ab_channel=Lextremely

One of my 1uz in my ls400 is on 920,000 miles she’ll easily do a million and everything still runs perfect, did the cam cover gaskets recently was clean enuf to eat your dinner off them cams, kal your literally helping keep 1uz’s around the world running with your knowledge keep it up for us owners

Found a 93’ ls400 here in the US, complete factory 1uz 279k, the only reason I’m still thinking about buying this engine is it’s a Toyota engine. Going to tear down this 1uz to freshen it up and put it in my 84’ Hilux, ironic how both of those topics were both mentioned in this video.

I have a 1992 LS400 that still looks great but needs all the rubber bits and plastics wiring clips replaced. Everything is brittle and falls apart... Also a metal shaving fell into the intake and underneath an engine valve when I replaced the starter... "Little man with a hammer" waiting to happen... I feel like I am digging myself deeper into a hole the more I work on the car... Can a guy refresh the 1uz and remove the metal shaving without pulling the engine out of the car? Thanks for the videos by the way. This is an awesome channel 👍

Hey man I've just come across your channel and I've just brought and now drive a 2000 toyota crown and it only has 48xxxkms should I be going through and cleaning everything when it gets taken apart to upgrade things like the cams intake and few support things and how often should I service it do ya think

Hey mate, just bought myself a 1uz to put in an unknown vehicle as of yet. Found your channel last week and have been studying up. Question for you though, where is the best/cheapest place to buy parts? My usual sites i buy off have discontinued some of the rebuild kits and such. Cheers.

Love your work and passion for these motors. do you have any motors set up to drop in a surf rescue jet boat for sale , if so would love to talk

Hi old mate I’m getting past it a bit but I have decided to swap out an is Lexus an is200 with a 1-2or 3 uz-fe and can I patch a uzfe engine harness into my 200 harness and ecu if so how much would the said harness cost

Does anyone know the ARP main bolts code with washers?

Descaler acid works well. I guess that's the same as your al18.

I wish all the guys in SA would watch this video. And im wondering how many will watch it..... Up here in Botswana almost all the Mercedes Sprinter buses fitted with the legendary 1UZ have all been a dismal failure. I asked some of the drivers where the engines have been fitted, and they point to a garage either in Pretoria or Johannesburg. One such sprinter had some "jerry" cans fitted high up the rear doors because the garage had failed to address an obvious fuel issue problem (It appears the whole conversion took 5 days, on a non-prepped motor) and were anticipating an obvious excessive fuel consumption issue. The vehicle did 150km and the motor died, highway side break-down. After diddling with some wires it roared back to life and did the first trip home with about 2 fuel stops (for a tank that size!!!). At the base the bus broke down on its 1st trip with passengers on -board and had to be towed back to town. The second trip it did 100km and motor died. They called in an electrician and he failed to bring the motor back to life. Within the next few weeks they sold the bus to another operator 500km away and he towed it to another garage in Joburg. Engine prepping.

Would you recommend redoing rings and bearings during a prep?

That looks like a Holley intake manifold for an LS GM engine. Is that a manifold that is available , it would look bad ass popped out of the hood of my Plymouth Duster

When I you going to open workshops in South Africa?

Id love to work alongside with you and learn from you. I'm obsessed with toyota lexus products and want to find a way to keep as many on the road as possible

I have a question, what would I need for to gain 400 horsepower from a pre 93 1uz, I was thinking of supercharging but I don't know how much psi is safe nor do I know what parts I need to handle such force induction, if you can please lead me into the right direction budget is 5k in US. Thank you so much.

Does anyone know how much it would cost me to ship my engine to this man and have him sort it out ahahah

Hey Kelvin I just bought a 1UZFE ex -boat engine off trademe to put in my Jetboat Are you any where near Timaru ?id love to get engine checked over and freshened up

Hi, I was curious if you know what the max non-darton sleeve size that can be installed into a 1UZ?

Van the engine be swapped into a ford explorer 2005?

So how much for you to strip down and refreb one

Also what the 1UZ heads flow unported vs ported?

Did that first engine have a blown head gasket? That oil sludge looks like it was mixed coolant. Kinda brown / milky look to it.

do u guys got partners around christchurch?

Can we put a 93 1uz with 96 five speed auto

كفو 400مكينت ال اس

How much do you charge ? To do that

PLEASE ANSWER THIS 👋🏻 Can we tune the 1UZ-FE engine from Crown Majesta 2002? What can we do to enhance performance?
