Thanks for sharing the details, I love following along!

Ok, one more update for what's to come:

I went on a short vacation for my Nieces birthday in Puerto Rico. Her boyfriend is a mechanic and works on mostly German cars. He was really interested in learning about my project, and we talked at length. One of the things I discussed was the possibility of going with a Drive by Wire setup to simplify things. The option is only $225 for my M600 and would eliminate the TPS and IAC and any issues with linkage. The Holley project is completed but I am just not happy with the linkage. Even though I matched the geometry of the OE TB, the Holley feels harder to actuate, and gets progressively harder as it opens due to springs and the attack angle of the linkage. Today he emailed me that he is sending me a TB and pedal he had left over from past jobs. The TB is a Bosch 74mm and the Pedal is from an X5 BMW (PART NUMBER UNKOWN AT THIS POINT). Both known working as they were "test parts" so to speak so basically new. All this for less than $20 IN SHIPPING. I will report back on how this all fits up. In searching, the TB should be a perfect fit, hopefully the pedal works as well. I found this (see pic below) from a seller in Australia for the TB. Anyone know of a supplier in the States that has something like this available?

Hi Bill -- you won't regret going DBW.
I wasn't aware of it working with MoTeC's hundred-series ECUs?

That adapter is readily available from Vibrant:
"Bosch 74mm DBW Throttle Body to 3" HD Adapter #12470"

Making a pedal mount and brace won't be difficult, either.

Chris,

I was looking back at old emails for info and stumbled on the one you sent me about DBW and started to investigate it. The license is not awfully expensive, and it will really simplify things once I figure out how to program and wire the pedal and TB in.

I have another question for the brain trust:

Does anyone know of an adapter for the factory fuel rails to AN style? I found the ones for the female ends but not the mail ends. They are 16mmx1.5 inverted flare I believe. Will I need to contact BoxterGT to see if he can just make me a line to connect them?

here is a pic of what I am trying to convert:

They should have the connectors you need: https://www.batinc.net/

Or instead of adding adapters -- use the original hose ends, put new hose on them at the lengths you want, mark the orientation, and send them to Len so he can crimp in some modern ethanol-safe hose.

I came to the same conclusion and spoke to Len. He is checking his stock of hose ends for me.

thanks for the info.

Bill, What Bosch coil number are you using? Looks like fun build.

Dual Bosch 0 986 221 024 coils on one output from a Motec M600. This was recommended by Motec. They provided me all of the coil data info to program the ECU as well. They really fit well using the smaller NGK plugs (BKR8EIX). With the origional Boch plugs they stuck out a bit too far and would have required an additional gromet at the valve cover to seal it up and keep them from shaking around.
