- Proof that from gen 2 engines onwards the 1uz is an interference engine.
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
Kentucky Boy here 🤠 .. I've personally snapped timing belts in a 5m Supra (82-85) , a 7m Supra (86.5-92) ,, and , 2 sc400's , one 92 & one 94 , no engine damage whatsoever , love my Toyota's !! Driving a 97 sc400 now (light rods) , & guess what ? Just installed a new OEM timing belt , that crap isn't happening to me lol.. Hope everyone is having a great weekend 👍
Kelvin you are a top person to learn from. All these keyboard kings let them talk all they can. You are doing a great job love your work.
Thanks.
Thank you so much for clearing this up when others were saying mixed things. This is my first big engine I'm working I and I wouldn't have gotten very far without your channel. Keep it up!
Wow, I just assumed all were interference, cool info, thanks again.
Glad it was helpful! Cheers Kelvin
10/10 on timing belt remove technique.
Haha. I was in a hurry.
That was freaking awesome!
Love the animals at the end, the munching and walking on the grass with the birds chirping was some asmr for real. Thank you for your knowledge ive learned alot from you.
Glad you like it. Cheers Kelvin
Kelvin...im a lucky bastard for sure....a year ago we went round and round on changing a belt.WP, TB, Starter, injectors....etc..(non-Toyota belt)....was the issue I was sent a 91 tooth belt... never started....tird for three days...thinkin it was cam sensors... got a OEM belt toyota part. Reinstalled and ya know what that takes .... installed and it has 8K miles since....purrs like a kitten. One lucky bastard signing off..
THANK YOU FOR YOUR HELP. 1997, "Coach" LS400 IUZfe20. 196K.
Mr. Kelvin, always love seeing your amazing knowledge of these engines through your videos! REALLY contemplating wanting to put a UZ engine into my 1977 Chevy Camaro, but have a few questions and thoughts. I don't have Facebook, which seems to be your more prominent form of advertising beyond UA-cam. Is there a link to a website as far as pricing for parts, pieces and services that you offer? Maybe an email address or a better form of asking in depth questions for sorting options? I currently have Qty. 3 early Gen 1 engines at my disposal, along with a 4wd/awd 2UZ 4Runner, and quite a few ideas that really need some extra knowledge to sort through possibilities!
Thank you! This is great 👍
Glad it was helpful!. Cheers Kelvin
Literally there isn’t a Toyota publishing copy wrightpiece of literature that disagrees with you . First gen 1uz was always listed as a non-interference engine. The only other possibility is that first gen you have with the 1st gen rods and gen 2 pistons. I’ve been researching this setup for a while and it seems that unless you have .500 lift Kelford or similar aftermarket camshafts it WILL become interference. Only option at that point is to fly cut new valve reliefs, thus lowering the chance of bent valves but decreases compression .
It’s amazing the utmost gall of people trying to reverse the well known . It’s all for views and arguments.
Well made video once again. 🤙🏼
Thanks. This engine is 100% a gen 2 engine. Ive checked it underneath when I had the sump off. Its just got a gen 1 intake for wiring as, if you noticed old yellow isn't presently in the workshop. You are correct, toyota has had this info around since 1994 but guys still dont get it right. We are doing a gen 2 piston, gen 1 rebuild soon. Cheers
@@CartuneNZ Well I am following with enthusiasm. We are looking at a 1uz engine build for our Plymouth Duster. I found a ‘94 LS400 that I am picking up in a week or so. Hopefully the center/mid sump fits .
We will be dropping my in some cams for a little lope but otherwise cleaned up, new bearings, rings , mls Cometic gaskets and HD fasteners. Maybe Prius COPs and a turbo down the road. Kelvin, is there any of the factory ECU’s that can be tuned ?
I heard of an LS430 ECU but see no confirmation
@@docfischer7291 I have videos of ls430 ecus being reflashed and more waiting to be released.
@@CartuneNZ I must have missed that ! I’ll search through your videos again. Thank you Kelvin.
Doc
Thanks for the info. I think the confusion comes specifically from the 95 sc400. I got one with gen 2 visual stuff on top (Ignition coil), but i turned it over a couple of times without the timing belt and the valves didnt touch the pistons at all. Dont know what they did with that year.
Correct. There are sub models of sc400 with the heavier rods which run later than 94, and there is the factory mismatch as you mentioned. Ive seen it myself, confirmed factory numbers. I'll do a video on rods and pistons at a later date.
@@CartuneNZ That was my issue in the brain. had a sc400 that looked like but wasnt the same as 97 1UZ
So the 1997 SC400 has a non-interference or an interference engine?
I have a video specific to the sc400. ua-cam.com/video/uYYGvr49Ark/v-deo.html
Thanks for the info Kevin, I have a 1uzfe myself, but I really struggle to figure out if it is a gen 1 or gen 2. I tried tuning into your video around the 1.15 minute mark where you mentioned the coil facing up and a few other distinguishing features of the gen 1, mine looks identical. But I still am unsure sine the gen2 also looks so similar, what else can I use to make sure I have a gen 1 or gen 2?
This might help. ua-cam.com/video/VLZkPL4J5kU/v-deo.html
@@CartuneNZ 100% helped me!!!! Thank you very much Kevin, this took me ages to figure out!!!!
learn''em up Kelvin......!!!
Thanks
Can you swap heavy pistons into a light piston engine?
I have a 1uz from every generation I want to do some extensive work and experiments with these. The small block design is what draws me in the most. Very modern for it's time and capable with competing with new.
Yes I can swap the heavy pistons for the light pistons and vise versa
Quote “94 was a long time ago....”
Yep it’s been a while since you first started at the Cartune and I worked at Midas and we become mates ....
Hi, do you sell fuel Rails for 1st gen 1uzfe, I'm from Canada, and im wondering if you ship here, Cheers
I have a few sets of gen 1 fuel rails. I think I may even have both options , the early and the later Gen 1 units. I'd have to check. Cheers Kelvin
Nobody has done (well I can't find knowledge on it) a 1uz bottom with a 3uz top in a gen 6 camry(2007/2008 camry sportivo)... do you have knowledge on whether this can be done? I've pressumed it might be too tall but I can't find anything on it on the interballs.
So basically whether you say yay or nay pretty much decides the future of my ckc build (commy killing camry). If not then could you recommend an engine that will fit and dear God don't say a fricken 2gr because that's been done so much it's been beaten in to the ground.
Thanks for your vids mate keep them coming
That Ram is what’s called “fluid gen1 to gen2”
It’s can be non interference or interference as it chooses moment by moment
Often that moment is when I'm not carrying my ram attitude adjustment stick too
So my my timing belt is not on right it's out of timing car won't start the belt didn't break do u think the valves bent? Please answer I love your videos
I don't guess. I test. So I would be testing your engine to confirm if its damaged or not. Cheers Kelvin
Hello. I have a 94 1uzfe and I want to drop it into a 95’ Sc300 body …. Will this work or will I have some re-wiring to do?
Are you wanting to fit just the engine with engjne harness and hopeing it will all plug in? Thats a no, for all versions of uz.
i have a 1st gen 1uz can i run the later style mass air that's round instead of the big bulky one?
I have jobs where I've swapped from early management and afm to later afm and management.
Is there a way to make my vvti non interference if so how?
Sure, using a set of custom pistons might do it if they have suitable valve pockets, however you will also likely lose performance
So Kelvin are 2UZFE's interference engines?
The 2uz shares a very similar head and piston design as the vvti engines, the early 2uz same head style without the vvti and later 2uz vvti and all have the ability to clash valves to pistons if belt is not connected. Interferance for 2uz.
😂😂😂 love the demo
Thanks for the compliment. Cheers
Kelvin, I hope this calms the keyboard warriors ;) Was that sheep just shorn? I noticed some trailing fur...
My sheep are wiltshire. They self shed their wool. Thats my arsehole ram who is less than friendly and when with the girls he's very protective, read he chases anyone out of the paddock, hence his aggression towards the young bull.
Just bought a 1992 SC400….No interference then? Yes!
The secret is to maintain the engine and its not an issue either way.
It actually makes me rather angry, that Toyota does things like this. If they change things, I wish they would just rename them.
Remember they never touch if the belt never breaks.
Non vvti non interference… vvti is interference right?
Maybe watch the video for the correct information.
So it's non-interference.
😂
Gen 1 non interferance, from gen 2 all interferance.
