Hi....... my project go on so slowly the stock throttelbody from the meg2rs has 40mm diameter. It is possible to use the throttlebody from the meg3rs (45mm diameter)?? of course with customized meg3rs intakemanifold Mechanically that would be no problem, but it fits from the elecktrick /control of the ECU ?? greetings
I did this on my mk2, the wiring is different between the two TB's, i did have the wiring diagram for this, but not long after i fitted the mk3 TB i removed it, i had a couple of occasions where the throttle would not do anything, had to stop, turn the engine off and restart then it would be okay for 2 minutes or 2 weeks you would never know. I had it mapped with it fitted and they said there wasn't any advantage in having it fitted, the standard 225/R26 TB is good for over 500hp. I kept the 250 manifold and made an adaptor to fit the 225 TB to it and i didn't have any further problem with the throttle not working.
Thanks for your information. Pin assignment I have ... have the visu data if there error messages ?? or did you have to read error memory? thanks
