Twin Turbo '74 Duster
I don't know if this is the right forum for a turbo/fuel injection build, if it isn't can a Mod please move it to the correct place.
Starting off I fuel injected my duster about 3 years ago now, I ran a stock 5.2l from a '94 dodge with a 727. I utilized all of the factory engine wiring and a MP ECU and just supplied the required constant and keyed on power. About a year later I tore the car down again and had my first go at fabrication and twin turbod the car. The turbos used are T3 (.48AR exhaust) Ford SVO turbos, utilizing magnum manifolds. With everything put together I ran 7psi on the stock rotating assembly with no tune. Since then I've added a methanol injection kit that is actuated by a pressure switch and upped the boost to 11psi.
Right now the car is disassembled and will be sent of for paint shortly. While running this setup I've noticed the short comings of the OBD1 electronics in a force induction application ( The computers aren't easily tuned, it's prohibitively expensive and isn't very precise). So since the car is torn down I'm going to be placing a 5.2l from a '99 dodge 1500 in place of the old engine as well as a 44RE to replace the 727. I've just finished modifying the upper trans cross member to accept the wider tail section.

I should find time to do the lower cross member and the trans mount this weekend. I'm posting this up because I know a lot of people have questions regarding a turbo mopar and I think there may be some people interested in what is involved to put and auto overdrive into an A-body.
