Toyota "Preparing" Hotter Supra GRMN, Says Chief Engineer

[A70TTR]

sure, but I wouldn't underestimate the standard cars... that's where all the focus is going to be until the GRMN comes out.

granted, my estimate doesn't take into account that head design which is admittedly a bit past my expertise.

My uneducated guess is a half year from first release or five months from GRMN release.

there's a car for everyone and every goal, but most times the initial base cars are already way past the factory upgraded ones if there's a release delay, but this is all just conjecture anyways.

Couldn't agree more. If ppl are able to push the GR Supra to lengths of the GRMN car, or beyond, before it gets released.... I would be ok passing on it. Especially if I'm saving my shirt from high markups. But, it's all relative to the buyer as to what they want.

I am pretty sure that the tuned base car will outperform the GRMN version in stock form in terms of pure hp

Of course, but just like the MKIV TT 6spd’s, the top tier cars will get the tough-er hardware . I would feel better with a highly modified car packing beefier components from the manufacturer....that’s just me.

Like I’ve said before, “think MKIV TT 6spd, but as a MKV.”

I like these little treats.

So do we have any guarantee that the GRMN is going to be made in any quantity over 100? Or even sold in North America?

That’s a good point. But I am certain they will not be very limited. Toyota has to recoup the development costs of their engine and all the other equipment it’s packing. If they only sell 100 they will have to be stupid expensive or Toyota just doesn’t care about profit anymore.

Considering the Supra hype in NA, Id be surprised if they didn't

Yes... you're starting to catch on. If the new Supra is a run away sales hit, they will still sell fewer Supras in all of 2020 than Ford will sell Mustangs in a single month. The economics of the GRMN model already doesn't make sense.

I'm going to place my bet on timeline for that power level at right around where the VR38 was... so, I'd say ~2/3 years

which is coincidentally about where I place GRMN release

Yeah that sounds about right. No doubt there will be some guys that will bolt a big turbo and start push the limit just to get the 4 digit number, but the proper way is after let's say HeadGames or VAC Motorsports start looking into those heads. N54 has 84mm bore and it has the tiniest intake valves, 31.4mm partly because to have room for DI injector partly because the dome shape is weird. B58 has smaller bore size and i fear it has even smaller valves. The integrated manifold is something new to me and i don't know if it should be upgraded or even how to do such.

The major drawback is the trans in my opinion. If it had DCT i would be all over that car because the upgrades already exist and are proven to work to whatever TQ you throw at them. The torque converter though never had a upgrade solution. People have for ages tried to upgrade their ZF 6hp trans and they couldn't. The TCU is too complicated to get the work. Hopefully some of the development from Hellcats can be transferred to these cars. If there is infact an alpha car with 6MT option around, i think the best thing about that car is using that car's coding and software to convert base cars into manual cars.

The wild card would be running a Syvecs standalone which can control DCT and swap a gearbox from M3 in there.

I'm thinking there will be a greater number in total production (i.e., LFA with 500 cars in total). But what do I know .

 

[A70TTR]

I think there is a much better argument for a Supra GRMN, just based on the forced induction platform. that adds instant headroom to all other modifications, especially given how good the chassis is.

the GRMN 86 on the other hand was fairly bizarre because it was $50k for nearly the same FA20 (+16hp), some CF and weight savings, a set wheels, and some seats. as such, they knew right off the bat that Japan would be the only acceptable market, and my understanding is that even there it took a while to sell them all (an accomplishment in and of itself at 100 cars). ultimately it was crazy expensive for very little gain, especially when everything was easily accessible in the aftermarket (including that small power bump)

there is so much more they can do with the A90, especially transmission wise.

 

[mkivalex]

^^ I.agree. It would have taken a ton of cost to bring thr 86 up in power a considerable amount with the engine that was in it. With the Supra there is a lot that can be done without the same investment. But the game changer will be a manual transmission. I am not sure if Toyota knows just how many people are most likely holding out or hesitating buying the car due to the transmission.

If/when they release a hotter manual version. I dont see any issue selling those cars

 

[A70TTR]

Yeah, if they had a manual, that alone would cause a ton of people to flip sides, let alone the other improvements.
