1uz MLS Head gaskets VVti onto non vvti and sharing ARP Head stud part numbers

[@1uzfe]

Kelvin I just want you to know your videos are the only reason I’m pursuing a 1UZ build. Here in north america people give up on 1UZs due to limited parts availability and general lack of knowledge. It’s either you get an ls engine or a jz engine or nothing at all. But your videos are just a fountain of information and its made the process a lot easier. I really appreciate it 🙏

[@jrjames9385]

You'd be right on all accounts. People are too lazy to learn how much can be done with this motor. Thanks Kelvin! As Fedora said, your videos are a wealth of information for those of us seeking it! Stay well and Merry Christmas 🎅🎄.

Always helpful buddy!! keep up the great work

[@flyingham7691]

this video is perfect i was wondering and couldnt find info

[@brianblank82]

Thanks mate ! Merry Christmas

[@CartuneNZ]

Merry Christmas back to you. Cheers Kelvin

[@FlangeMaster10]

Many thanks for all the videos this year Merry Christmas.

[@CartuneNZ]

Thanks. Merry Christmas to you too. Cheers Kelvin

Thanks for the info. I'm busy with an ongoing twin turbo 3UZ and stopped when we got to 693nm at the rear wheels. Obviously time for upgrades. I bought a set of the ARP studs as you suggested and they are in. Only one small fitment issue that will need your attention on a 3UZ maybe a Vvti 1UZ as well. The head stud on piston nr 1 that is nearest to the exhaust port needs some finesse as the timing gear of the exhaust cam touched the stud and nut. I had to grind the stud a bit shorter. The Allen key still works but only just. The nut needed the same attention. Just something small that might help the next enthusiasts. Philip

[@CartuneNZ]

All correct. I discussed this in the video. Cheers Kelvin

[@jdmmix]

Calvin great videos keep up the good work.

[@CartuneNZ]

Thanks

[@Adam-qk9pk]

Hi Kelvin love the videos , so informative mate. I was thinking of drilling my 1uz out to take 12mm studs I wanna push it past 1000hp is it worth it ? Or are the 10mm ARP good enough ?

[@FullBoostJ4]

Another informative video, appreciated 👍

[@CartuneNZ]

Glad to help. Hopefully this helps people for years to come. Cheers Kelvin

[@bvward]

Kelvin, I noticed that the rod bolts were for "Cracked Rods""... Do they work on Bent rods as well? if so, I need some! Thanks for the info. I wonder if ARP would consider offering a package with shorter studs, or a kit specifically for the V8's.

[@CartuneNZ]

I've also got one of those bend rod engines. Haha. Video coming for that. I'm not sure why arp dont list specific numbers for the 1uz range

[@CraigDoesDrift]

Hi Kelvin, is there a difference in thickness of head gasket?

[@mob187eastside]

What a view !!

[@CartuneNZ]

Sure is. Lovely spot to live

[@faraimulenga409]

Will the 2uz mls work on a 1uz non vvti

[@josuenava4555]

Which are head studs would you recommend for a boosted application making 600rwhp at most and seldom and 450rwhp for the majority?

[@CartuneNZ]

The part number from the video.

[@paulmeglasson1919]

The 1UZ-VVTi head will physically fit on the 3UZ-VVTi but it will slowly pour coolant into the oil pan and the dip stick mounts in the wrong place

[@aaronhill3443]

This was super informative thank you. I figured MLS head gasket required machine shop for 1UZ. I'm thinking it's about time for new head gaskets for my 250mi 93' SC400 but I'm not 100% sure. She might be burning oil but I know it's leaking it. Other than that it runs awesome and the oil isn't coffee and the coolant isn't miracle whip. I want to turbo my SC400 at some point too. On that note, I heard the stock ECU can handle up to 8psi- is that true?

[@FullBoostJ4]

I'm running 6psi on my stock skinny rod 1996 Ls400

[@CartuneNZ]

The stock ecu tune was very rich in the higher throttle / higher load settings and had very conservative timing so many people have used them in boosted situations. Some guys are successful and I also se heaps of guys which try and fail as it isn't ideal. I prefer to use an aftermarket ecu when I modify an engine outside factory parameters. Cheers Kelvin

[@FullBoostJ4]

@@CartuneNZ I'm looking into a Link ecu now Kelvin, probably the Monsoon if I can get my hands on one over here in the UK for a reasonable price.

[@CartuneNZ]

@@FullBoostJ4 monsoon is a great choice. Flick me an email which I'll sort after the break and we can work a deal.

[@fmn716]

Was actually chatting to mark about getting these. There is a guy on KZbin that was building a budget 1000hp 1uz. He also used arp head studs but used standard bolts where the scissor gear are. What’s your thoughts on this

[@CartuneNZ]

I think buying a set of ARP head studs and then using stock head bolts in the middle is a silly idea. I would much prefer having studs with all the same clamping force and stretch characteristics. The clearance issue are very easy to overcome. Cheers Kelvin

[@thedpfteam2423]

Bro. You made me laugh. 1uz gods didnt want us to see part numbers for sure. Lol

[@CartuneNZ]

Glad you liked it. Cheers Kelvin

[@Jxsh180]

Are the corolla head studs suitable for boost. And making 600bhp

[@CartuneNZ]

Easily good for well more than 600bhp and boost.

[@erkopihlak]

Any OE codes for 1UZVVTi MLS head gaskets?

[@CartuneNZ]

In my other video on the topic. Cheers

[@josephgale6630]

Do not go out and buy ARP Celica/Corolla head studs, as you called them. 203-5407 are actually MAIN studs from a Celica/Corolla that work as head studs on a 1UZ. Do not make the mistake I made guys! I bought the head studs for a celica/corolla and they are 50mm too long.

[@CartuneNZ]

Correct. Hence why I included part numbers to avoid this issue. Cheers Kelvin

[@georgepeprah5118]

Do you only work on toyota cars?

[@CartuneNZ]

I try to. We do a few others with 1uz fitted from time to time
