I fitted the throttle bodies to the Plus 4 myself. Following the instructions from Omex it was not particularly difficult but it has to be said I am accustomed to mechanical work.

Omex provide a kit for the 1600 engine, that their new kit for the Plus 4, uses their own high quality direct to head throttle bodies and they have simplified the installation from when I did it.

I am currently using the ignition map that they deveped for this system and that, together with the new, larger, 300 cell cat has made a great difference to low and mid range torque.

Their brochure can be downloded here.

The kit comes with a starter calibration but it would need to be tuned to match the exhaust system used.
