I spend a lot of time on the GM Performance website, and according to them, the T-56 Magnum can hold some 700-single-digit torque, and it's like $5k.
(Looking at you Tada, surely you can make a tranny that handles 3/4 that for cheaper)
Did you use an LS or a BB crate? V8-swapped Sciobarus are nice.
Neither, it's a 5.7L Toyota V8.
And you mated a T-56 to that? How?
Would be useful to apply to other engines.
I haven't yet. I will eventually. I mated the factory 6 speed (J160/AZ6) to it. It's not that hard if you know what you're doing or at least know a shop that does. All you need is an adapter plate, custom flywheel, transmission mounts, a custom shifter extension, and a custom driveshaft.
If that sounds expensive, it's because it is even without the cost of a T56. That's the only reason why I just went with the factory 6 speed for now, cost.
Some good news here is that the B48 and B58 are modular. Any manual transmission and flywheel designed for the 20i will fit a 40i. (Strength issues aside). Not that it matters as much as there already exists components for the B58 for a manual from other cars like the M240i.
The real nicety would be the existence of mounting hardware, hydraulic components and pedals.
Yes this would work nicely if built. Less components that need to be designed.
Keep it on the down low, we don't want Toyota/BMW to make it even more difficult than it already is.
I'd like to believe this is the serialized MKV he's talking about but he probably means it's the I6 not the lower spec I4.
I hope I'm wrong but those two sentences back to back makes me think only the I4 will get the manual transmission.
The test car this time was a right hand specification, but a turn signal lever was attached to the left side of the steering column (Japanese specification appears to be a turn signal on the left side)
And above all, the sound that reaches the ears was comfortable. The sound that is transmitted to the driver in the car is said to be "directed with a speaker" (Mr. Tada)
The test car this time is still a prototype under development, and further refinements are scheduled before release. Even after being launched, Mr. Tada talks about his vision, "Every year, we will make improvements by adding variations."
All excerpts from that article.
So if we want the best MKV we should wait 'till the end of it's production cycle
Hopefully it would get a manual transmission & 400-500hp, what it should have had from launch.
Let me add a few:
That article's pretty honestly written. Like it says the interior's all BMW and nothing but BMW, except for the instrument panel, that that part is all Toyota. They gave the digital panel an analog feel, unlike what BMW did.
It also says how the car doesn't comply with Toyota's in house criteria that all Toyota cars have to follow, like how low it is and how thick the door sills are for rigidity. It breaks Toyota's own rules for sake of performance.
Price is within reach of 86 owners, if they tried hard.
Toyota told BMW, mileage be damned. Just focus on performance.
Driving position was sunken not only for lower center of gravity but to give the entire position a sports car like feel, along with the positioning of the steering wheel and the gear lever. Can I read between the lines that they positioned it ideally for a manual gear shift lever??
Stability control can be completely turned off. Although even with it on, it's not very intrusive.
Final specs are not yet set in stone, and yes, it said that even with the 2 liter turbo, the torque was ample and that Tada also tested the MT model the other day.
Anyway, that's what I have from memory.
I have a hard time believing this part or at least BMW half-assed it. 340/382 for the EU and US spec, respectively, doesn't sound like they went all out. Knowing Toyota and their non-economic car strategy, they actually do dump a ton of fuel for reliability over mileage/performance, mostly with trucks and SUVs. From my experience the 5.7 V8 stock runs an AFR of low 11 to high 10 at full throttle and extremely low timing for an NA engine. You can run a blower or a turbo at 6 psi without touching the tune.
I'm pretty confident there will be a ton of room to increase performance and mileage, leaner is always meaner... until you blow a hole through your block
I believe he's referring to "Porsche-like" improvements
