Thanks! It is a customer/friend’s Darryl. You can it out on Instagram @gr_rally3

Glad you're enjoying it. Yeah it is awesome hey. Very appreciate for the relationship we have, the products we've developed together using both our mechanic and mechanical engineering skills. Also grateful to work on such a sick GRY. As for plans, pretty sure he'll keep it as a street car but setup for the couple of track days he days a year. He wants to get the most out of it without having to go down the MoTeC route. As time progresses more opportunities will open up on the factory ECU. No sequential due to the cost, not sure what he has/planning to do with the clutch especially for the track days. Stay tuned for more updates! Have you got a GRY yourself?

Thanks, Aaron! Triple awesome that you’re a GR Yaris owner, it’s a Rallye and a mechanic too! Just checked out your YT channel. Yes, that’s how it idled on the first start. It had already been tuned with the breathing mod upgrades before we started our series of installs. The Type A Kelfords sure are a step up. Ben from Benchmark is re-tuning it as we speak.

Always have to sneak it in 😎

Did you tune it with ECUTEK after installing?

@@denstoj nope its still running the stock map untuned. Hasn’t missed a beat or thrown a light or anything

@mercywing2 awesome, good to hear. Yeah shouldn’t throw any codes as it runs all the stock sensors.

Absolutely! Are you in the line up for one?

@@denstoj I'm ready to purchase the Corolla in the States when the automatic comes out. Gonna be faster in a straight line and around the track than a manual.

@arctictruck10 awesome! Hope it isn’t too hard to get your hand on it

@denstoj it's either this or a Golf R.

@arctictruck10 GRC all the way!

Thank you! Another video coming on Saturday morning (Aus time). The compressed air screwed into the spark plug hole is used to push up against the valves to hold them in place while we remove the valve collets to swap the valve springs over. Otherwise, when we remove the valve springs and collets, the valves will drop inside the combustion chamber. Less work than having to remove the cylinder head.

Which car and model?

Sick! You'll have to upgrade your rockers from the older cast to lighter pressed metal rockers in the Evo 4-9 4G63. They are backwards compatible with the older engines. Full details on our website: denstoj.com.au/products/4g63-pivot-retainer-clips Let me know if you have other questions.

Hey Cliff, great question. Yes it is a pull type clutch. It is hard to explain but you put a flat sided screwdriver (fairly wide) between the clutch fork and clutch release bearing end plate and twist. Applying a little bit of load to the clutch fork in the opposite direction. I wonder if there is a video out there showing this?

Excellent question and I am not sure what Daz (the owner) is planning to do with the gearbox to handle the extra torque. I'll have a chat with him as it's worth considering upgrading the clutch especially considering he does track the car. Sequentials are just too damn expensive! I imagine it would be difficult to find the OEM safety factor on the torque specifications of the gearbox. The best way to tell is from real world experiences of different setups and what it can handle. Do you have a GR Yaris and considering upgrading the drivetrain in yours?

@@denstoj Yes I have a Rallye which I mostly use on weekends, but I intend to run in the summer rallysprint series later this year. Just for fun though as I don't have the budget to compete with the guys with fully built tarmac cars. It seems like it's relatively easy to extract a lot more power and torque out of these cars, but the gearbox is a weak link. I've had that feedback from one of the workshops over here in WA that has a shop car that they've stuck cams and a tune into. They ran into issues with hard track work. Likewise there are reports out of the UK of similar issues at a range of tune levels with 5th gear in particular being a problem. I'd like a bit more oomph but I think for the time being I'll focus on handling and reliability mods. I used to have an Evo 9 tarmac car and the biggest jumps in performance came with tyres and suspension and a reduction in weight.

That would be fun for sure but yes hard to compete when the $ start adding up. Focusing on handling and reliability mods is a smart approach. Keen to hear how you go.

If only I could hit restart 😅

No worries. Let me know if you have any other questions.

Thanks Lukas!

Yep keen to see what Ben from Benchmark can get out of it on the dyno. Will make a video on it for sure. It’ll be tuned on Ecutek.

Thank you. Hope you learnt something from it.

@@denstoj Definitely did, I know people were blowing them up but not sure exactly why

@@CamberClub Send them the video :) Rod bearing failure due to oil starvation is the most common with aggressive driving in the FA20s but if it's in the head, it's going to be a rocker!

We'll find out once we get it on the dyno. Stay tuned, will release a video on it. 👍

What upgrades are you planning to do?

@@denstoj I would like to valve springs and head studs myself I just need the tq specs and sequences

Awesome. Great to hear you're giving it a go yourself. I did some quick Googling and looks like the workshop manual is behind a pay wall online. Or just watch our videos on repeat 😝

@@denstoj both 😉

That's it! How soon are you thinking of doing the upgrades?

Cheers! Will keep the videos coming. Awesome. Let us know if you have any questions.

Good question. It's a backup mechanism like in your B58 👍

You can never have enough preventative measures

@halorita yep, especially on such a highly strung motor

Thanks! Not sure sorry.

@@denstoj thanks, did a bit of digging. It's 39nm

@froshtyv awesome! Thanks for digging it up. Didn’t get a chance to check for you yesterday.

Cheers! Kelford cams dropping in on the next one.

What power are you aiming for out of this build? Are there any restrictions in your rally competition to use aftermarket engine internals? Just curious why you'd run OEM parts if you're building an engine for racing.

@@denstoj we use a 34mm turbo restrictor. All apart is free. However, we aim for high torque under 4500 rpms more than high horsepower at 5000 and above. Thanks for the quick answer 🙌

Ah got it! So many low end pulls from the cornering. That levels out the power between competitors nicely. Have you considered running the 267-EZ Kelford Cams?

@@denstoj I already have the 267-B, but now I see that the EZ ones can solve it

Yes, the EZ would be the ones to get for your setup. Kelford are running a 10% off promotion on their G16E cams for July as they just finished a big run of production. 😎 Let us know if you have any other questions.

Thank you. We’re busy editing the rest of the videos in the series. 😎

Thanks! and yeah, when you're leaving the head on, it's not simple. Were you thinking of doing it yourself?

@denstoj yes but me and my friend aren't mechanic haha 😅

Good on you :) awesome to hear you and your friend are keen to get hands on. You might have to watch the video just a couple more times while you're doing it ;). Having the right tools will be important too.

Hey goat3800, yes if you’re one of the luckier ones, it is possible a rocker could dislodge safely and tuck itself neatly in the tapet cover and the 2nd exhaust or inlet valve will keep doing most of the work. You will notice it low on power or running a bit odd. How is your 86 currently running that has you concerned? Thanks for the question.

Hey @silviamadness, it's very important to give the master cylinder and pushrod clearance. There should be no load on the pushrod while in the rest position. You can shorten the stroke of the pedal by shortening the pushrod. The height of the pedal is adjusted through the pedal stopper. There is no other adjustments you can do as clutch take up is controlled by pressure plate. Let us know how you go and if you have any other questions feel free to ask.

@@denstoj I appreciate that very much. I’ve been adjusting, kind of back and forth to see what feels best. It seems like a bit of give and take thus far, but still playing with it. Did you guys use the factory bearing carrier as well? I know the Nismo twin clutch does not come with a bearing carrier, so it would be assumed to reuse the factory one. However, I’ve been told a taller bearing carrier is to be used instead. Thanks again for responding

Good question. When correctly installed, our rocker retainer clips do not cause any additional wear or noise in the rockers or valvetrain. The clips are designed to be non-intrusive under normal operating conditions, engaging only when the rocker loses pressure from the valve spring. This is achieved by the existing groove in the hydraulic lash adjuster where the clip attaches. It is narrower in the middle where the clip and rocker normally operate and wider at the top, so the rocker is "caught" by the clip if it tries to fly off. This solution is similar to the system used in the B58 BMW engine found in the GR Supra, which does not exhibit any ticking noise despite being a high-performance and expensive engine (see video clip below). Our clips do not affect the regular functioning of the valvetrain and will have a lifespan equivalent to the other valvetrain components. Did you have any other questions? ruclips.net/user/clipUgkxuOoS4rvnUSjs-JlaFsIuwjUv-lLUeEen?si=NcihwGaRVDiaxEdB

Could you share more about your concerns?

@@denstoj my concerns are that the clips seem to clip on very easily and i wonder if they can slip off easily at high rpms? if the rockers can pop out of place at high rpms what's stopping that happening to the clips? i have an evo 6 and am looking to upgrade the valve train specifically to rev higher (Safely) so am intrigued by your product

I totally get your concerns. Sure, while these clips might not counter severe valve float, they serve as an added layer of security. They've been successfully used in high-stress environments, including world-time attack winning Evos and drag cars that push over 1,000+ hp at up to 10,000 rpm. They pair nicely with upgraded springs when pushing higher RPMs and of course, we wouldn't build a 4G63 without them. Let me know if you have any other questions.

@@denstoj that sounds awesome! Is there any videos anywhere I could check out please?

We're working on a video. For now there are a couple of Facebook posts to check out: facebook.com/share/da3qR9tW9kz9rgpY/ facebook.com/share/bVRZJEuvG8bnwnU7/

Glad you found the video helpful! The transmission doesn't necessarily need external support when the engine is removed, as it's well-supported by its own mounts which makes things easier. Are you planning to pull your 86/BRZ motor out?

Yeah our editing could definitely do with some help and be improved. Do you do video editing freelancing?

Good question. We’d have to look into it. Were you thinking of doing any other upgrades to yours?

@@denstoj well so far I just have full bolt ons and and tune that’s can rise the Rev limit a little higher then stock maybe in the future when more stuff comes out for the car I will

@darkabyss5604 ok nice, I’ll look into it for you and let you know

@@denstoj okay sounds good thanks 😁

I've ordered both the rocker and lash adjuster in to inspect for you properly. 👍 Might be a couple of weeks before I have them though. ☹️

Hey Alexis, you can order straight from our website (link below). We've got them in stock and ready to ship out to you. Let us know if you have any questions. denstoj.com.au/collections/parts/products/fa20-fb-rocker-retainer-kit

I'll have a chat with Dennis and see what he thinks.

@@denstoj Thank you very much

@2018wrxaddict no worries

Haha yep just got to learn it the hard way

Hey! Do you mean spare retainer clips in case you break any when you’re installing?

@@denstoj yes exactly!

@bobbykosha6503 with careful installation it won’t be an issue. Happy to help you out though, drop us an email rockers@denstoj.com.au

@@denstoj email sent! Thank you for your help & have a Happy Easter!

@bobbykosha6503 no worries! Thank you and same to you

Appreciate it! Anything else you’d like to see?

@@denstoj Unlikely, but an FA24 full teardown.

@@haifai3916 thanks, yeah not planning to do it anytime soon but will keep it in mind. Happy Easter!

Thanks! Just clarifying you mean running GR Corolla exhaust springs in a GR Yaris?

I like your eagerness! Just confirming though, which swap are you referring to?

I’m not sure what the owner is running now after he has re-tuned it sorry. 🤔

Oh damn, that sucks. We’d have to look at one of our heads. No luck fishing it out with a magnet?

@@denstoj no luck with the magnet even tried flipping the engine. If I were to start the motor with that in there what would get damaged?

@hackiess8146 double damn. Yeah I wouldn’t recommend starting it. Did you want to email us some photos of where you think you lost it and we’ll check on our head when we can? Rockers@denstoj.com.au

@@denstoj yes im gonna snap some pics real quick

@@denstoj I think it sent

Is it after every turn/lane change or only under autopilot?

Yep! And Toyota should have put the G16E-GTS in the GR86 😎

I think they biggest constraint was the turbo itself since it sits under the engine, it wouldn’t have the clearance for the BRZ. They’d probably have to somehow move it into the engine compartment.

@@NJMICP3176 Yeah the, design of the BRZ, with its low hood line and tight engine bay, definitely makes it challenging to fit a turbo. It's not just about fitting, but also managing heat especially for long term reliability - possibly straying from the BRZ's ethos of being a straightforward and driver-focused. It's always an interesting balance! What have you got?

Would be cool but expensivr and unreliable

@@razokevX Yeah would be very cool. We're thinking of doing a swap. 🤔

Hey! On the FA20 in the BRZ, the clearances need to be between Inlet 0.10-0.16 mm (cold) and Exhaust 0.21-0.27mm (cold). We have a worksheet to help when setting up the valves here: docs.google.com/spreadsheets/d/1Ld78m5UFX5meDGyf2uukR9JtfcJP9cHZLUvrdrSbaMA/edit?usp=sharing

Are you trying to rebuild your VVT at the moment?

i am preparing to. I have tried watching this 6 times. I appreciate the effort. Not an affective teachingtool for me.@@denstoj
