Brent C Posted April 14, 2019 Report Share Posted April 14, 2019 Hi Rob The injector I have fitted on my six came from a Vauxhall Senator. I know these would not be available to day; I did my conversion in 1996. You could look at sourcing a set, from a scrapped 2.5 BMW, as theses are similar to our engines, in that they are the same CC and a straight six. You could then send the injectors to one of the specialists, to have them ultrasonically cleaned and inflow tested, I used a bloke off Ebay, he sent mine back with a before and after chart, showing the improvements gained. The ones I have are yellow and are larger in diameter, than the Lucas injectors. I don’t know if there are any serial numbers on the injectors and I am reluctant to start pulling one out as the car is running so well, I don’t want to disturb anything. I too have used the original throttle bodies, so had to open up the holes to fit the electronic injectors. I went to the minimum depth, so that if I wished to go back to the old PI system, I could still fit the original nylon insulators, although they would have to be installed upside down, to get the “o” rings to seal. As with any conversion, you will have to install equipment to the engine that was not really designed to be there. I managed to get the holding down clamps. I also got the fuel rail from the Senator, but again I had to modify these to suite the six. By doing this you can save a lot of money. Brent Quote Link to post Share on other sites
rob7 Posted April 14, 2019 Author Report Share Posted April 14, 2019 Hi Brent Thanks for your reply was hoping to be able to get injectors to fit straight into my thottle bodies but it looks like I will have to go down the root of opening up the holes in my thottle bodies thanks once again for your help Rob Quote Link to post Share on other sites
GT6M Posted April 15, 2019 Report Share Posted April 15, 2019 Cant say about the bosches, but fitted Keihins, the TBs need a 9/16th drill down em, basicly aboot 20thou moer than standard. note this is only at the bottom part, not touching the top part at,o top bit seals wid the help of an O ring,or 2 if yer pedantic, or can just use the bigg seal ont bottom oft injector the O rings are better, as injecter dont ..wobble aboot , plus ye got moer room for the bottom seal as ina GT you aint got the bonnet clearance. can get em in either low or high impedence, both got + an - s for each type low impedence, then ye,ll prob need ballast resistors, unless yer ECU can handle both. ten a penny in scrap yards as fitted t,most jap cars Aim t,get some frae a car with 120-130 ish BHP max,ish , as then the size will be aboot right ie cyls 4 /120=30x6 cyls=180 BHP will need t,get 2 sets cos they be a set of 4 on most cars, bigger engined cars they be too big https://www.google.com/search?q=keihin+fuel+injector&client=firefox-b-d&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiV1t334NLhAhUT8uAKHTcVCJMQ_AUIDygC&biw=1140&bih=673&dpr=1.5#imgdii=PdBOX7aQn01bUM:&imgrc=diZA5kHZFz9hJM: Quote Link to post Share on other sites
PodOne Posted April 15, 2019 Report Share Posted April 15, 2019 Mazda MX5 blue 220cc or yellow tops 280cc IIRC would probably do the job running about 80% duty cycle. As for ecu not cheap but I'd suggest a second hand Adaptronic 420e or the newer Universal from EFI Parts in Runcorn. Email or speak to Chris. Top bloke and excellent service. He might even have a base MAP if he has done a TR in the past to get you going.The adaptronic forum is good support as well. The ecu. will run everything you could ever want from a std EFI to forced induction, traction control etc. Andy Quote Link to post Share on other sites

rob7 Posted April 26, 2019 Author Report Share Posted April 26, 2019 Found some injectors on eBay from a 2.5 bmw will have to drill out thottle bodies as advised by Brent on earlier post but it looks like the fuel rail will catch the thottle bodies has anyone had this problem before Rob Quote Link to post Share on other sites
Harald Posted April 28, 2019 Report Share Posted April 28, 2019 You have to create an adaptor like the one in the picture . Harald Quote Link to post Share on other sites
rob7 Posted April 28, 2019 Author Report Share Posted April 28, 2019 Thanks for the picture but have now removed some material off the thottle bodies should .be ok now thanks again Rob Quote Link to post Share on other sites
TriumphV8 Posted May 2, 2019 Report Share Posted May 2, 2019 Unfortunately I lost the pictures of that modification. Maybe Jochem will ad some pictures with that solution. After removing the material from the bodies also the surface for the bolt holes must be set deeper and none of the holes can be used for taking off the air pressure for the ECU and manifold pressure for the booster. The bigger injectors have the simple disadvantage that they need short times at idle and small load. As we are in the range of 3 milliseconds any influence from voltage or anything else becomes more relevant and the metering is not that precise. From that reason it became a rule that under full load the injectors should have the size that they are permanently open with a small reserve. Quote Link to post Share on other sites

Andreas, sorry for the delay....I was unfortunately occupied with some of my other issues... The CR Bodies were skimmed off so the fuel rail can be positioned closer since the injectors no longer need adaptors. Quote Link to post Share on other sites
BaldiGit Posted August 15, 2023 Report Share Posted August 15, 2023 Has anyone gone EFI and kept there original throttles in place? Rather than use a single throttle body on the end of the plenum... I have a Vitesse which I'm just starting the restoration of. And I have managed to find a set of TR throttle bodies for it and it seems a shame to choke it through one throttle body.
