500hp upgraded valve springs and Camshafts On Our GR Corolla (Gymkhana Grid GR Corolla EP10) 

You know it’s gonna be a sick GR Build with lamspeed parts 😎 well done boys

I'm a Toyota Master Tech, new chain tensioners come with what looks like a blunt thumb-tac installed into the hole to keep it locked. The trick I use to ensure I don't do what happened to you (as has already happened to myself) is I use the thumb-tac with a string tied to it. I've had one pop out and fall into the oil pan, but I was able to retrieve it via the string.

Can’t wait to see what those lsds do!

The added details are great, especially with such a new platform. Motive is about the only one that has explained their process with the GR Yaris, so it’s great to see a different perspective.

Awesome video guys! Great set up. Have added to our playlist!

If we are going with "John the mechanic" I vote we start referring to Dave as "boost God". The internet isn't ready for where this groups headed. Good job boys, see you in a week for some Rocketwagon fire.

Excited to see some skids after the engine and new differentials.

Any new videos coming out soon? Can’t wait to see what you have done

We have the same spec gr but mine probably will never get to this level

Just sub'd you guys are ABSOLUTELY KILLING IT! About to complete the break-in period on my GRC and I cant wait to start modding it. Love the in-depth tech talk, I've been learning so much. Can't wait to see the result!

Great job, bros! I had to sell back my GR Corolla, and these videos are my cathartic therapies. I'm eager to see you guys in the competition. Btw please record everything and post it here 🙏 is the only way I can see you. I'll be cheering you from here

drip king dave!

Nice job there, we should do some cooperation!

You got any events coming up in the Corolla or is this all prep for next season.

Will this void your warranty? 😂😂 JK Jk Looking good Nemtec 🤙🏽

Yeah was really informative So I'll know what to do and the pit falls 👌🏾👌🏾

You’re a mad lad.

Be noisy for 15 seconds not minutes.

I would trust these guys with my car that is for sure

Man ok...what is crazy... the block looks so close to the geo metro block......😮

Hah shimming diffs is exactly how I used to shim my electric Airsoft gear boxes. Neat.

Really loving the in depth look into these parts, especially the differentials. Hope you touch on this again, in particular regarding the shims/setting backlash of the rear diff etc 👍🏻

Kind of fell on your videos. Expected the typical bolt on dyno here you go stuff. Really pleasantly surprised by how serious you guys are and how confidently you tear into things. Well done. Definitely love the details and the step step presentation. Subscribed.

Are the cranks keyed or do they use friction washers?

it’s getting exciting .So sick.

Interesting. Are you guys pushing for 500hp on stock compression? Looking forward to seeing the dyno results 😀

2:47 Dave's got the bling!

Why resurface everything on a fairly new head? Or was it more of a clean up? Anyway, the more details the better. Loving this project!

Awesome gr bros

Aren't the aussie guys getting 500 hp on the yaris engine without doing alot of upgrades??
