FYI, Anyone wanting to mate a small block Mopar engine to a late model trans needs to talk to this guy:
Peter Willie
2470 Seanine Drive
Victoria, BC, Canada
V9B 4Y1
250-474-2980
Pwille50@shaw.caNot only is he a dedicated Mopar man, he is an absalute transmission genius! (auto or manual, modern or vintage). I just visited him last week, he has a small block A-body 5 speed project in his shop right now and really scienced out all the bugs, it's a slick deal let me tell you! *He also drives a sick SS/A (that's a 4 speed Race Hemi A-body!)

Clair,
received yesterday the package. Thanks so much!
Everything is working. Don't know what the Tacho reads, but it works..
The Shield needed indeed minor grinding on the holes for the Starter. But not that much that it would be visible...
Fan-TASTIC!! Glad that stuff made it in just fine, and again I'm amazed how fast you get the parts on the car. You even painted the dust cover, but left the PN sticker exposed to draw attention away from the fabricated parts...  
Now if I can just get motivated to get out in the garage and work in this 100-108* weather we've been having lately. About all I can get motivated for at the moment is lifting a nice big, cold beer...

Buschi and I are approaching it slightly differently, but the majority of the parts will be the same.
Bellhousing, clutch slave/master cylinder, pressure plate, flywheel, bearing retainer from a 93-?? Dakota V-6 with the AX-15 5-speed trans
Transmission, shifter, driveshaft yoke from a 1988-1992 Toyota Supra Turbo
Custom clutch disc (Advance Adapters = $120, RAM = $250)
Custom pilot bearing (or input shaft sleeve)
Custom speedo cable
Custom hole in floorpan
Custom Trans X-member
Modified clutch pedal
Those are the items I can think of off the top of my head. The thread really shows a lot of the effort that went in to the swap for Buschi (I haven't done mine yet), and we'll just have to put some effort in to collecting all the PN's and such.

Thats all on parts... You need to weld a new Torsionbar x-member. And you can see above and on previous pictures that you will have problems with the exhaust system. Clair, this car is now a good car for driving every day. And saving 2 L gas on 100km is a good effect too. Man, I love what we did...

so, at all I drove maybe 600 miles the last weeks. And I love it - especially on the Autobahn...  This is what my Speedo compared to the Navigation system reads: km/h (mls/h Orig Speedo) .......... km/h (mls/h) Navi. 45 (28) .......... 50 (31) 55 (34 ) .......... 70 (44) 85 (53) .......... 100 (62) 100 (62) .......... 120 (75) are there speedo gears with different gear ratios on the market (Toyota)?

Don't forget that every competant speedo shop (and I'm sure there are some in Germany) can make a correction adapter in case there are no stock speedo gears for this application.
Good luck,

Finally - disc brakes on the front.

Greg, I haven't compared both yet, but here's photo of the 154 piece I took a couple pages back:  It appears that it has some eccentricity to it like the Mopar, but I was thinking that the AX-15 unit was close to the same size/shape as the older Mopar units. I've got both out in the garage, just need to find time to get out there and compare. Clair

On update... the 154 speedo pinion adapter does NOT have any eccentricity to it, so there's probably not much that can be done about changing ratios. Interestingly, a Mopar speedo pinion slips right in to the 154 adapter and fits like it grew there. The tiny lip seal even fits the Mopar like it should, and the overall length is about right, too.
HOWEVER, the big deal is that the 154 speedo adapter is on the pass side, and the Mopar/AX-15 is on the driver side, so the pitch of the two gears are opposite. That means that even though with some surgery you probably COULD swap pinion gears around, the teeth won't mesh. And, without some eccentricity to the adapter, you couldn't adjust pinion gears with diameters different than the one that came stock.
So, what is it going to take to get a non-adapted accurate speedometer reading? Obviously, the tires and rear gears need to be the same - not an easy trick. Tires on a stock MKIII Supra Turbo were 225/50-16's (24.86" tall), and rear gears were (apparently) 3.7, 3.9, or 4.3:1. Yikes. Short tires AND low gears. With only one gear on the speedo pinion, I'm not sure how the speedo was calibrated. Seems like it could be done with the ECM, but I'm pretty sure that the speedo was mechanical on this series of cars. Can't say for sure, though.
Other thoughts?
Clair

OK, looks like the orig speedo is reading about 20% lower than reality. That size in a BFGoodrich Radial T/A goes a mile in 806 revolutions, so with 3.23's and a 0.75:1 overdrive, the engine should be turning 1,953 rpm. So:
45 kmh (28mph) = 911 rpm
60 kmh (37mph) = 1,204 rpm
100 kmh (62mph) = 2,018 rpm
200 kmh (124mph) = 4,036 rpm (autobahn, right?)
You COULD get a tire that was 20% smaller, but that would look rediculous. Maybe a speedometer shop could recalibrate your speedo? Or maybe keep the GPS in the car...

Last idea.. (I know I said that last time...) In the spirit of "Don't raise the bridge... Lower the river.. Got this message from a gent over on the Turbo Dodge board. He put an R154 in a RWD Acclaim behind a Turbo 2.2 with a DOHC Neon head. I asked how he got the speedo reading correctly with his setup: "I worked around that problem. I installed a Stewart Warner electronic speedometer in the dash and combined the Toyota speedometer drive with a Chrysler drive. I attached a couple of pictures. If I wasn't using the Chrylser factory cruise control I could have just used an electronic sender off another Toyota, such as one I picked up off a Toyota mini van. The Stewart Warner speedometer will work with just about any type sending unit. To calibrate you just drive a measured mile and push a button." Sounds like a plan. So, the other part of the equation (for you) may be this. A dash panel that allows you to use the aftermarket gauges you already have in your Dart along with an adjustable speedometer. http://www.redlinegaugeworks.com/popups/popabody1.asphttp://www.redlinegaugeworks.com/products.aspMight be worth the expense.
