anybody smallblocked a d50? how about turbo'd one?
D50's are awesome burnout machines, even with a stock 4-banger. The weight on those trucks is pretty much centered completely over the front wheels, so there's nothing to hold the back tires down.
My '87 D50 was a joke in the rain. If I stopped at a redlight, I'd have to slap it up into 4-High before pulling out, and then shift back to 2wd otherwise the truck would sit there and burn the tires through all 5 gears. Go to pull out on a steep hill, same deal, slap it into 4wd before letting the clutch out, or it'd just spin the tires.
I could downshift from 5th/overdrive to 4th at 45mph and break the tires loose just by easing the clutch out and giving it some gas.
Whatever you do, if anyone decides to keep the original 5-speed manual transmission (for a turbo 4-banger swap) STAY AWAY from that transmission!!!
Here's 5th Gear / Overdrive from one of the 7+ KM145 transmissions I killed. They can barely handle a stock 4-banger and are known to launch parts through the transmission casing.
That one split 5th gear open like a rotten egg. I had another transmission that blew up and spit gears through the casing (got dents and holes in the transmission tunnel on the '87 from that transmission).
Use a mazda RX-7 transmission instead if you have to have a 5-speed with the 4-Banger... Or one of the automatic transmissions from a D50, the 3-speed d50 auto is a Torqueflite 904 and the Overdrive is an A500.
