Just curious if anyone has successfully replaced the electronic throttle body with the throttle body from an 850 (drive by cable instead of drive by wire). If so, how difficult is the conversion and does it work?

+1 i've been curious about this myself.

I think it would be a good amount of work, and possibly needing an ECU retune. You wouldn't be able to use cruise control, and the ECU that wants to control the throttle couldn't, causing error codes and a bunch of potential problems. And there is the entire mounting issue. The drive by cable has the throttle mounted in a different area, so you might need to swap the entire intake manifold. The actual pedal stuff wouldn't be as hard, simply swap it in.

Just my thoughts on the subject.

List off the top of my head:

New ECU, they are completely different between 98-99
New Engine wiring harness
New Body Wiring harness
Intake manifold
t-body
Intake plumbing
Gas pedal
Throttle cable


That's all I can think of right now. But to answer your question, sure it's possible but how much time and money are you going to spend before you realize it would have been easier to buy a new car.

Ok. Does anyone here want to buy my really nice 2000? New battery, alternator, battery cables, good tires... How about a trade?

how much?

Danny don't be hating.... it's not that hard.

I've only done one and here's what it took and what I found;
Parts:
Intake manifold w/throttle body
Accelerator cable
Gas pedal
Intercooler piping from intercooler to Tbody
Associated gaskets and some tubing

What it takes:
Install all the components, leave ETM connected and relocated somewhere in engine bay. You'll also need to connect the POT box from the orignal 'gas pedal' to the new gas pedal so ETM/ECM/TCM still gets an input.

What you give up:
No cruise control, No tracs control (also means you can smoke the tires all you like so maybe not such an issue).
Under normal driving it works find and you don't even notice there is a difference with the exception of better throttle response however if you start getting into throttle and the ECU or Tracs tries to pull some throttle back (to prevent wheel slip) and sees it isn't happening you will get a CEL. Also helps if you have a stage upgrade with torque limiting removed (Prevents power pull back via ETM from early torque development).

So not the best solution, but I'm paid to try this stuff out so I thought I'd share my findings...

[dmelviØØ7]

I guess that's one way to do it

Hey I'll be the first to say it's ghetto...!

Thanks for your input Lucky, prior to this I had not heard of a succesful conversion.

The bigger issue here for me is that these cars are can be had pretty inexpensively now, so unless you have a free (or close to it) donor car it dosen't make much sense. Ohh and you save yourself lots of work

[MrWinkey]

So the ECM doesn't have a constant MIL due to missing ETH and pedal sensor signals?
