Fuel injecting a triumph6
I retrofitted fuel injection to my son's GT6 spitfire. Total cost was less than $500 USD. I simply modified the Zenith stromberg carbs to hold port style fuel injectors (2 in each carb, 19#/hr injectors), and added a high pressure fuel system near the motor. No return line, no modifications of tank, no problems. The ecu is a Megasquirt I on a V3 board. I made the fuel/injector fittings by drilling out plumbing fittings. I got the injectors off ebay (used) for $10 plus shipping, and the other sensors from a junk yard for $15 total. I made my own relay board and wiring harness so the computer controls the fuel pumps. To make it neat and more up to date, I added a new air filter box so it could breath even better. The box also holds the air temp sensor.
The car presently runs better than ever before, passes emissions, and starts easily when it's cold out. It started on the second try, and then It took about 2 hour to tune it so i was very driveable, This was the first fuel injection project I ever tried. The people at DIYautotune were very helpful when I was getting started. I have subsequently done extensive testing on my MGB, which I have injected with a variety of carb setups. (2 1.5 su's, 2 1.5 Zenith strombergs, 2 1 3/4 Zenith strombergs). The best so far is the 2 1 3/4 zenith strombergs. Very VERY peppy-like (or slightly better than a new late 60's/early 70's B). The details of that are posted at [www.mgexperience.net] and references cited in that thread. For more details, read the referenced posts first and then email me at drivers-seat@juno.com.

Re: Fuel injecting a triumph6
Having raced GT 6 and Vettesse's in the 60's and 70's we found that the first thing I would do is replace the Trans driveline rear end axles and hubs and the radiator to start with. They are junk and if they are any good you canget good money for them which can go for replacments. These parts are too week for even the stock 4 cylinder spitfire . If you want to can call you and go over what we did and how we got 220 hp and total reliablity out of a stock bore vettesse.
