Toyota FR-S : Official Name for the FT-86 Concept?

[ichitaka05]

^ That's why ppl use full stand-alone or sub-ecu and leave the main ecu alone. I'm praying that Cuz of this, Subie's ecu won't be hard to crack from 2011~

It's when you try to add a turbo that things get messy. Toyota really needs to make their ecu's flash-able, if only for this car. Hopefully since Toyota is using a Subaru engine, Subaru will also help develop the ECU. Does anyone know anything about the ECU?

Side note: A EJ20H (twin turbo) would be pretty sweet!

EJ20H = Valley of Death. There's a reason they stay in Legacies and aren't a common swap.

As for standalone's, no big deal. May have to wait a bit for a plug and play unit but it won't be too bad. For example, a P&P Haltech Platinum Sport 2000 for my car is $1900 installed with a base tune. It's the rest of the turbo install that may be a pain, strictly from a packaging/fabrication standpoint.

I'm still worried about the strength of this new transmission.

Looks like I have some reading up to do about Subaru engines lol. I'm not to familiar with Subarus.

Aren't Subaru's fairly easy to tune using the stock ecu. The transmission is another area of concern. I know the wrx transmissions have been known to be weak whereas the sti transmissions are better and ca handle more power.

The EJ20H uses a sequential twin-turbo setup. First one spools, then the other. The Mk4 twin turbo Supras use a similar system. On the Supra, as the first one approaches its set boost, the sequential system begins to 'pre-spool' the second turbo so that by the time the first one is at full, the second one is smoothly continuing. (Rough explanation). The EJ20H uses the same idea, but apparently not as smoothly, and I've heard of a lot of complaints of a dead spot from lag at the transition from 1 to 2 turbo operation. They call it the Valley of Death. It may be over-dramatized, but the EJ20H doesn't seem to make it into swapped Imprezas.

An advantage the transmission will have is not having AWD that will be trying to break it on hard launches. Wheelspin will be the fuse, at least for a stock car. But if this car comes out NA and with no plans for a turbo (god forbid...) the transmission (and diff) may end up being the weak link, even if you boost the motor yourself.

Like I said, tranny will be built by Aisin AI. Some of the JDM FR companies uses them (Nissan, Mazda, Toyota, Mitsubishi) and GM too. Tranny gonna be the least of my worry

It depends on the purpose of the tranny. Twin Turbo Supra got the V160/161. This was the transmission of the gods. NA got the W58. Not known to handle much more than 50% over stock torque.

If this car is destined to be a NA only 2.0L there is no reason for Toyota or Subaru to ask Aisin to build it to take more than 200 lb-ft, there is no reason for it to be super strong.

I'm just throwing out worst case scenarios, so we'll all be that much happier when the 305 hp, bulletproof 6 speed, 2.5L Turbo Sti/TRD, easily tuned with a Cobb Accessport, version comes out. (pleaaaaase...)

That's the thousand ft/lb question

Don't forget, it's gonna be 6sp. I don't know much NA engine w 6sp tranny that is weak.

Thanks for the info! I was thinking it was a parallel setup? Learn something new right?

The MOTHER-LOAD! (...time to come back down to earth lol)

Everybody knows the MR-S came with a piss weak engine from the factory. So does the Miata. A powerful engine does not a sports car make. In either case, the power is a turbo or a 2ZZ swap away.

anyway.. back on topic. Anybody stop to think that FR-S might be for another car that can drop the top?

agreed about the holdens and falcons, never drove a mustang but whatever. yeah il stop talking shit, this opinion comes from me not liking that car in general (aesthetically) and i realise that other ppl dont share my opinion. so i promise to stop hating on the mrs

[CyberFormula]

i would much rather have the JDM 2.0 sti engine than the 2.5

and as far as power goes, if it comes factory 270hp....its already pretty impressive for me. No need for 300hp/300tq.

[blur]

I'm probably going to debadge and rebadge the car once I get it . . . FR-S is odd.

But torque is delicious. Mmmmm... torque...

I'm almost positive they'll call this car something cool in Japan. They don't really use the alpha-numeric names over there too much...ie: Sylvia vs 240SX, Fairlady Z vs. 300ZX or 350ZX, Integra vs. RSX, Trueno/Levine vs. Corolla GT-S, etc, etc...so we can debadge ours and get JDM badges to put on the car...that's what I did to my IS
