"I talked to IPT today, and they said that a well kept 241E automatic is good for up to 175-200ft/lbs of torque. Their modifications should allow for 400 HP, which is well beyond the OP's target.
They do a lot of things to the transmission.
* Valve body is custom calibrated to provide firm, positive shifts
* High performance pressure regulator boost valve is installed to prevent sluggish line pressure rise
* Extra clutches are installled
* Modified solenoid assemblies are installed
* New one-way clutches/sprags are installed
* Lube system is redesigned for increased flow and cooler operation
* New flat bearings are installed in all locations
If you put a transmission cooler, increased pump, and more clutches like the modifications from IPT do, you will have a better transmission."
Ser ut til at IPT kan bygge en A241E kasse som tåler 400hk. Bør i så fall holde plenty til en 2GR som skal brukes til litt koseturer om sommeren

"Turbos and automatics actually tend to go very well together. You can stay on boost while it shifts and avoid some of the lag that you get when you aren't abuse shifting a manual. Would the ECT in the MR2 be a good match? I have no idea - but I'm not going to simply jump on the 'automatics suck' bandwagon when there are many scenarios in which it wouldn't.
My Corvette has a 4 speed and I wish it were Automatic. The Auto available for my particular car was a Powerglide 2 speed...and I think I'd still prefer it for that particular car."
" You would think a forum of enthusiasts wouldn't be so blind when you mention the word "automatic". Most modern automatic transmissions can shift faster than you can on your best day. What in the hell does having a big torquey motor have to do with anything? Based on people's assumptions, you would think they haven't driven an automatic transmission since 1962...
Given that Toyota has 5 and 6 speed automatics, it's certainly not a matter of not having enough gearing. Seriously, how cool would a 6 speed paddle shifted 3sgte be? I wasn't kidding when I said you can get an aftermarket transmission controller and paddle shifters and have buttloads of fun in an MR2. Screw two-steps and launch control. How about programming a transmission to shift at the right RPM every single time? How about never ever missing a shift again? How about completely predictable runs down the strip every time? How about fast fast fast downshifting on the track without dealing with worn synchros, imperfect rev matching, and tons of weight shift?
Nah, it's a slushbox. Couldn't possibly be any benefits to that. Let's just throw the whole idea out and never explore it. After all, everyone knows that the best of the best innovate by never trying new things and always sticking to the old and familiar and comfortable.

Litt spennede kommentarer fra et par velkjente guruer i MR2 verden (Bill Strong og David Hawkins), to godt respekterte guruer
Må bli en preppet A241E kasse skjønner jeg
BTW:
the point of DRIVING an MR2 is driving the car, and that includes shifting it like a man.
Blir vist ikke MANN(!) lengre om jeg bytter til automat
