    89 sundance turbo to 94 shadow motor swap

    How do i get around all the emissions system to not have the headache of replacing all the vacuum lines? Regular grocery items are what you may possible spot on the Food Lion Ad.

    You only need a couple of vac lines to begin with. I would think vac lines are the least of your worries in a turbo conversion?

    You'll be getting rid of the vast majority of vacuum lines that you don't need. It's really quite simple. I would also ditch the parts store manuals and get some factory service manuals if you can.

    Re: 89 sundance turbo to 94 shadow motor swap

    well i thought about the 89 sundance because it was the car with the turbo , and the wiring harness that i pulled out of it came from four or five big pugs that were just underneath the dash and i matched them up to the ones in my car and they plugged right in, although the computers actually look really similar to the other one

    While the connectors may mate up the wires in them may not go to the same things. That's where the factory manuals would really come in handy. I don't have either of those years on hand or I could make some scans for you.

    I'll add that 94 is going to be SBEC II electronics while the 89' is a SMEC. That's a big difference in itself. That and the fact that there is a physical difference between the turbo and TBI computers even in the same year...

    You don't need a stand alone. You can go to www.boostbutton.com and see the best stuff going IMO. You will have to run the 89' Computer though as the later one won't have the injector drivers necessary to run the 4 injectors. You could get a 90-91 unit and go that route, but the 89' SMECs have more support anyway.
