I had my TR3a converted using a Jenvey heritage weber look-a-like throttle bodies and an Emerald ECU. I was very pleased with the set up, easy to start, smooth and torquey with an added 20bhp and improved fuel consumption. The car had a reasonably well tuned motor with 89mm liners producing 115bhp prior to the conversion. This was a before and after measurement on the same rolling road.
The car has left me now although is in the hands of a member on this forum.
