trerynn Posted November 18, 2016 Report Share Posted November 18, 2016 EFI conversions are usually praised for power economy and reliability. Some of our members say they did their own system, was it diy installing of a kit of parts or was it trips to the brokers and scanning eBay gumtree etc? Not wishing to reinvent the wheel would any one of the true DIY converters please produce a detailed listing of the parts obtained from breakers etc to do the job.

Mike G Posted November 18, 2016 Report Share Posted November 18, 2016 HiI converted my 6 in 1996, to Bosch “L Jetronic” EFI. By modern standards, it is fairly basic, with parts sourced from a Vauxhall Senator, with an ECU supplied by the late Mike Pumford. I kept the original manifolds and opened them to accept the larger diameter yellow injectors. The car starts just like modern it pulls smoothly even from cold and has covered 63,000 miles since being installed. Including 2 trips to Italy and 2 trips to Spain. I did all the work, in my modest garage. Obviously the parts I source are long since out of production, but it is proof that these projects can be carried out by the average punter. Also a number of issues I had to overcome are still relevant on a more modern set-up.Mike G Quote Link to post Share on other sites
had17462 Posted November 18, 2016 Report Share Posted November 18, 2016 Hi ,I do happen to have the bits from a Vauxhall senator as I was going to do the conversion but never got around to it,if of any interest let me know Nick Quote Link to post Share on other sites
Nick Jones Posted November 18, 2016 Report Share Posted November 18, 2016 Very out of date and not including the ignition side (which is also long done) http://www.shadetreegarage.co.uk/Megasquirt1.htm This was a true junkyard-special made entirely from used parts, except for the MS ECU which was home-built from a kit. It's done alot of work since then, including being thrashed all over Europe several times, and almost all the hardware is unchanged. Some more here which was my PI conversion. Also mostly used hardware. Starts about post #10 http://sideways-technologies.co.uk/forums/index.php/topic/5167-nick-mk2-pi/ Have a poke around on here too. http://sideways-technologies.co.uk/forums/index.php/forum/6-ignition-ecu-and-fuel-injection/ Nick Quote Link to post Share on other sites
DOG_MORGAN Posted November 19, 2016 Report Share Posted November 19, 2016 What are the the benefit and the total cost to convert from a standard tr6 pi thanks billy Quote Link to post Share on other sites
TriumphV8 Posted November 20, 2016 Report Share Posted November 20, 2016 Benefit and costs widely spread relying on the person who does that job. Also the benefit depends of the state of tuning of original engine. A homemade EFI on a TR6 Carb was established by me spending about 1000 Euros including buy & refurbish of inlet manifolds with ball bearings. Out of the box systems start about 2000 Euros and a swap done by a specialist fully done might be around 4000 Euros including setup on rolling road. Mine is about 20HP over the carb version and accepts wilder cams without lumpy idle what allows a gain in power for the daily driver to about 35HP without running into trouble. So where you can end at 135 HP tuned with carbs if you do not want to sacrifice driveability the EFI can go beyond 170HP. Fuel consumption is about 15% less to before if ignition control is employed what I did and is included in my estimated costs. This is not a must but as all requiered data are already in the EFI its a good idea and easy step to do so. Always keep in mind that a PI or carb can be trimmed for good economy than the gain in better fuel consumption will be less and there is a gain in power with the EFI and if the engine was set for power before the saved fuel will be more than 15%. The benfit is that EFI can do both: Very reliable at part throttle and perfect power development under high load. Quote Link to post Share on other sites
