91 740 b230f want to convert from regina to bosch ignition do i need whole engine harness from a bosch ign car and ecu or what




thanks

 

Why? The cost of conversion would be far greater than the savings you may get having the Bosch...

 

Are you thinking of going turbo? I can't imagine any other motivation for removing a decent injection system. You'll have to pull the transmission and swap flex plates too as the tooth count is different for the two systems. Of course, if you want to go turbo, you'll want to dump the AW70 and get an AW71.

 

want to convert form rex ignition to bosch and use 740 or 940 turbo fuel system if possable

 

Pretty much what I figured. There's at least one guy who's turbo'd a Regina car on turbobricks. I haven't really read up on the conversion but...if you have more time than money it can be done. Find and read the build thread...I'm sure it's enlightening. If you have some money to put into the car, I'm thinking the guy probably used MSnS rather than convert everything over. If you want to keep the stock turbo computers, I'd recommend getting a complete parts car so you have every thing you need right there.
