Triumph Spitfire, 1500inj with 4x42mm throttle bodies
Posted: Thu Jul 24, 2008 6:05 am
I rebuild a 4 cylinder 1500cc triumph engine to electronic injection,
despite some Triumph specialists, who said it couldn’t be done.
I had to make a 36-1 pickup on the crank, nothing off the shelves by Triumph for this.
I disconnected the mechanical fuel pump and used the normal fuel line as return.
An extra fuel line with 2 connections on the fuel tank and a 4 bar fuel pump.
I basically used 4 throttle bodies on Weber intakes with Weber air-filters
and after the manufacturing of the 36-1 pickup and sensor it was a down-hill battle of putting
parts on the car and wire them to the computer.
The project started in the start of 2008 and was finished after 5 months,
basically because I was driving around the first 2-3 months with 2 carburetors and
having the MS logging more and more data.
Also I had 2 small band lambda injectors installed and after installing the electronic injection
I waited to long for ordering a wide band sensor and get the car running smooth.
The ignition is a basic table that came with the computer, working with the old 12v spark coil and spark distribution.
I simply made some runs and heard the car fire (heavy sound) and put the ignition map 3
degrees later, till the nasty sound was gone.
It isn’t the most expensive car and it isn’t the fastest now, but I still enjoy working on it and I
am looking for next month for the APK (Dutch yearly check).
working on the VE-table now;
one happy customer;
