Re: Never before has so little power been made from so much displacement!

Ok must have missed that, I never worked with anything with such low compression or radial or aircraft or mitsumotorcycle or antique with fuel injection let alone all combined.. I do have a couple Corvairs tho wink

Certainly someone will chime in where to ship.

3)better shift linkage

You think one of those PTO boxes that somebody linked to kind of too late for this build for #1?

I've been thinking about #3. Pretty much all of our MR2's could use that. I hate the damn shift cables.

It's too late. when i pulled the motor i cut the cross members instead of disassembling the motor to get it out. did that yesterday, there's no going back now

as for the shift linkage, what i had setup made the stock MR2 setup seem like a super sharp shift setup. it was almost impossible to tell what gear you were in. i had to guage the gear i was in based on where the shifter would not go. if it was in 2,3 or R the shifter would not quite go all the way forward (about 1/2" from the stop) and the same for the other direction.  and neutral was a whole other ball of wax. the only way to guarantee neutral was to jam it in a gear then go forward till you felt it fall out.

it should be possible to retrofit an MR2 with push/pull rods to remove the slop

I think I miscommunicated. It's my understanding that the Kinner-engined version has now moved back to the theoretical from the actual. So what I was getting at was if you were doing it again (and setting aside the caveat that if you were doing it again from scratch, you wouldn't use two 90-degree boxes), do you think that one of the PTO boxes would be a better alternative than the 3000 diff?

I think you're right about retrofitting the MR2 cables with a solid linkage. The only thing that concerns me (other than time) is that the solid rods wouldn't really want to accommodate the to-fro rocking of the engine. I dunno.

Ahh, you're asking about a lessons learned kinda thing.

I'd skip all that noise and orient the engine and transmission to fit a short driveshaft to a boat v-drive. you can get a 1.65:1 overdrive ratio in there. that would turn the motor's 1950rpm to 3200rpm and i'd put that strait into an audi diesel transaxle so it has taller final drive.

I'd link the engine to the v-drive with a double guibo equipped driveshaft using the 96mm guibos instead of the weaker 93mm ones like i used.

the transmission / vdrive driveshaft would probably be torque tube style to align the flywheel. that worked really well with the goldwing box.

the stock MR2 has a left-right motion restricting rod on the driver's side top mount. the motor should never shift left/right so i'd just go to the rear firewall with the rods and into a bellcrank that makes both rods go left/right from these those rods could connect directly to the transmission. the stick in the cab would likely vibrate with the engine a bit, just like a longitudinal stick would but it should be crisp.
