I actually installed this kit in my Mk3 Supra swapped 2jzgte, yes sir I also had to modify my transmission tunnel but no cutting. I'm using a Wildwood clutch master cylinder with a twin plate 1000hp/1000ft lb clutch and it feels stock so I'd have to say that your customer's car needs that to be changed out. Now I have spoken with a company here that builds these transmission for more power and also sequential set-ups. Tick Performance here in the States and they recommend Dex 3 even after the break in. The guy I spoke with said it works best with the internal pads/ material of this transmission. They have seen some come back with less than a thousand miles for rebuilds. I'm going to stick with what this shop says... Dex 3. I'm also thinking maybe by this car being an automatic you have to do more modifying possibly! Not sure just a thought 🤔. Anyway great install video.👍🏁🏁🏁👌👆💯🌟

I installed same kit last year to my RHD Supra. It was originally W58 car, the only modification I had to do for the tunnel was more room for the reverse lockout solenoid and that's all. Only things I have broken so far is 2 units of 3/4" Wilwood master cylinders, now switched to 13/16" Tilton with grannas's own res and it feels so much better with the Tilton ST246 clutch. Overall the gearbox feels amazing to drive but it is rather noisy during engine brake. Redline oil.

Nice video. You’d think after all this time of doing the installs GR would have sorted that stiff peddle.

Interesting to see your take on the kit. I installed mine on axle stands on my drive and while it was PITA, getting gearboxes on and off layed on your back is a PITA anyway tbh lol. What's really odd is I didn't have to modify the trans tunnel on my UK car, but you can clearly see the lack of room in your video. It's tight against the passenger side, but not touching. When I installed the kit, GR originally supplied a smaller wilwood slave and the peddle pressure really wasn't an issue. The only complaint I had with the smaller slave was the clutch would disengage a nice inch and a half off the carpet, but then it wouldn't properly bite until quite high up. Joel happily swapped out the wilwood slave for the large bore Tilton. I haven't had a chance to test yet, but once the single build is done I'm looking forward to giving it a try. Having ran dextron 3 and the 75w, the dextron 3 is quite a bit louder, but once I knew nothing was broken, it doesn't bother really. That gear change and the box strength is worth the offset, IMO.

Let me know if you play around with the master. The grannas kit come with 13/16th (.081) bore. It is quite heavy but my softened up.

It’s strange that I have a 1995 rhd jdm one and the clearance looks slightly better than in this video. Thanks for your honest review though, interesting comparison to some videos saying that tilton clutch drive like stock. 😅

Isn't the reason the fitment in the tunnel was bad because you were installing a manual in the auto tunnel? It's my understanding that regardless of market, going from auto to manual transmission requires hammering the transmission tunnel. I have a RHD 5 spd manual and I only had to do minor massaging for the lockout.

How well were the gear ratios suited to the diff? (Did it still have the auto diff in place) P.s I still need to get a move on and film my r154 review - some good points highlighted in this video which makes me glad with the choice I went for. Thanks for the advice 👍🏽

Thanks for uploading this video and your review. I am also in the process of going t56 from an auto supra real soon...Did Grannas reach out to you about your issues? will he make any adjustments to any customer who will go from auto to manual for rhd supras?
