    TR6 EFI Conversion

    I have just finished converting my '69 TR6 to EFI. I have fitted an Emerald K6 ECU, triple Jenvey Heritage Throttle Bodies on a Racestorations DCOE manifold. The engine is a saloon block with a lightened & balanced rotating assembly, bored out to +30. The cylinder head is a Fast Road spec' from Peter Burgess and the cam is a PH2 from Newman. The car went on the Rolling Road at Emerald on Friday and produced 178.9bhp, I was very pleased with that.

    What are your thoughts of adding EFI to stock TR6 engine?
    Would there be any benefit?

    You would get much improved starting and improved MPG I would expect, on a US spec' car there is always the Pattonmachine injection conversion you could do.

    Nice! Looks like triple webers. Is that the injection system?

    Exactly what I'm looking for to put on my 3.4 MK1 Jag. Have seen these on the TRs, and one on a Jag, looks exactly like the multiple carb engines.

    Yes, each body holds two injectors, the centre body also has a built in throttle position sensor.

    Are you still using a cable drive tachometer?

    No, I had my tachometer converted to electronic, it takes its feed from the ECU.

    Don:

    You installed the O2 sensors on the header branches from the outer cylinders, 1 & 6. I think I know the reasoning, but please explain.

    And also curious to know how you dealt with crankcase ventilation.

    The 2 ITB's feed 1-3 and 2-6 respectively
    The 2 tubes in front were the easiest.
    Crankcase ventilation?..., same way the stock did it

    Hi Don,

    Can you give some info about those throttle bodies? Are they custom made? If not what are they?

    Thanks

    Thanks. They were mainly ITB's Looks like it was a small operation running out of a guy's garage (or something like that). Stopped in about 2017. Lots of photo's in google.

    Re: TR6 EFI Conversion

    When I was considering EFI for my TR3, I was looking at these throttle bodies from Borla Induction. As it turned out, I got the original SUs dialed in so good with a wide band O2 sensor that I abandoned the EFI project. I have a bunch of new stuff that I accumulated from that project such as fuel pump, MegaSquirt (w/wiring harness), temp sensors, and MAP sensor if anyone is interested...very reasonably priced.
