john.r.davies Posted January 17 Report Share Posted January 17 Recently , someone asked about ways to install EFI on a TR6, but I cannot find that post! Whoever, they may like to look at the Standard Triumph Experimental Department page on Facebook, Standard Triumph Experimental Department | 2.5PI Electronic Fuel Injection - anyone know why this development didn't get taken any further | Facebook Today this picture has appeared of a saloon, I presume 2.5L, fitted with a common rail EFi system. Some relevant comments are under it. Quote Link to post Share on other sites
The horseman Posted January 17 Report Share Posted January 17 Hello John, Have a look at my article in TR Action Issue 317 which describes fitting EFI. After a further rolling road mapping session the TR managed 33 mpg at 70mph heading to the Loire Valley in France during September last year, with no exhaust smells or problems in heavy traffic and ferry queues. There was pain, cost and down hearted times getting there but it was well worth it in the end. Ian Quote Link to post Share on other sites
john.r.davies Posted January 17 Author Report Share Posted January 17 Thank you, both who replied! I don't want to this, but thought it interesting that Triumph tried it, In the day. Maybe your suggestions will help the guy who asked! John Quote Link to post Share on other sites
harrytr5 Posted January 18 Report Share Posted January 18 Jenvey now has a trick injection kit that looks like the original. Very nice, have a look. Regards Harry Quote Link to post Share on other sites

I had my car converted to EFI successfully back in 2017. It was the full Emerald kit, with Jenvey throttle bodies, and their K6 ECU. I have covered over 30k miles, and it has been excellent.

saffrontr Posted January 18 Report Share Posted January 18 To get back to John's original post the Lucas EFI shown in the first post was completed in 1970, some nearly 54 years ago, and shown on Tomorrows World on the 8th January 1971! Does anyone remember this, unlikely methinks? The development car also featured an anti-lock breaking system, cruise control, contactless ignition and an electronic speed limiter. All of these are now taken for granted. It was also noted that the EFI would have met the prosed 1974 Federal and California regulations. Why did Triumph not take it forward at the time, I can only assume cost and in any case in 1970 they were already looking at the TR6 and big saloon successors. So have we made much progress in the past 54 years, well sort of in that there are or two EFI systems such as the Emerald that are readily available to fit to your TR6.

Hi Tom, I bought the intake manifold from Ramtech in the U.S. and the electrical wizardry from Kevin at EFI for Classic Cars, still a work in progress. I'd definitely have opted for the Jenvey throttle bodies had it been available. Richard. Quote Link to post Share on other sites
John L Posted January 18 Report Share Posted January 18 To me the Jenvey ones in the pictures above, shows with the yellow caps, to be the fuel supply line, so where do they get the vacuum from for the brakes, presumable the MU isnt used any more. John Quote Link to post Share on other sites
Richard71 Posted January 18 Report Share Posted January 18 Hi John, I assume the plug on the middle throttle body (or any of the three) would accommodate the original hose-barb fitting. Richard Quote Link to post Share on other sites

Does anyone remember this, unlikely methinks? Yes. I don't remember the broadcast but someone posted a link to the video which was on Youtube or elsewhere on the web. I've forgotten which forum I saw this. Might have been the 2000 Register - it's so long ago ... The video doesn't come up with a quick search. Cheers, Richard PS: Found it!

Andy Moltu Posted January 23 Report Share Posted January 23 You have several options throttle options. The new bespoke Jenvey manifold/throttle body kit. Modified standard inlet/throttle bodies. (DIY or from fredmillturn) Weber style inlet manifolds mated to DCOE fit throttle bodies (from Jenvey but good copies from China used by the Nissan 240s etc) As well as Jenvey heritage throttle bodies which look like Webers. All of the above can be mated to your chosen ECU, tps temp sensors etc. Emerald seems to be a favourite and has a built-in atmospheric pressure sensor. Just in the research stage so not done it myself yet. Quote Link to post Share on other sites

Just in the research stage so not done it myself yet. I got the whole package from Emerald, including the Cannon inlet manifold. I went for Jenvey throttle bodies, but the Jenvey Heritage look good. They were not available when I purchased all the kit back in 2017, nor the bespoke Jenvey manifold/throttle body kit, just released. Any questions, just ask. Cheers.

CK's TR6 Posted January 23 Report Share Posted January 23 It is nice to see both the increased interest and the increased availability of EFI solutions. The Jenvey offerings of three different approaches are very nice. Ramtech is also a good option, looks a lot like the Teglerizer intake. With well over a decade of experience with my installation my observations are, crank fired ignition is a worthwhile endeavor, sequential injection was an improvement (cam sensor maybe needed), not all O2 sensor systems are created equal, and lastly, for me, robust knock sensing is an area that needs much investigation. The picture is from 2011?2012? original installation. Quote Link to post Share on other sites
Hawk Posted January 25 Report Share Posted January 25 I explored this recently but the cost of the Emerald kit is (in my opinion) prohibitively expensive. By the time you factor in dyno work (and ignoring the instillation costs) you will be well over £6,000 for the 'basic' kit. Quote Link to post Share on other sites
harrytr5 Posted January 26 Report Share Posted January 26 20201220_181816_14238493111737.mp4 Yes the cost is a main consideration but it was an itch that I needed to scratch way back in time when I had my then TR6.Wind forwards a few years or so and I thought now or never. I drove Jerry Vincents TR5 with his home brewed EFI and I was hooked. First version(2010) was single throttle and converted the original Throttle bodies to accept Bosch injectors and fuel rail. Emerald ECU and hardware software from them. They looked after me and talked through the problems I was facing. I ran this fault free till 2019 and then fitted the Jenvey Heritage throttle bodies because I loved the look and performance. Always reliable. Horses for corses.
