                <div>That's great info, very extensive.  Months ago I
                  asked ITG UK if they had one in stock (NLA in the
                  "colonies").  They said that they had no stock (last
                  sale was 14 years ago), so it would be bespoke and
                  cost 71 UK pounds plus carriage, etc. Needless to say
                  I declined.</div>

            <p>I bet they have the pattern on file. It is just a sheet
              of  aluminum with holes drilled in it. They should be able
              to make them up on demand cheaper than that. But maybe
              they have a min. price for specials.</p>
            <p>At worst someone could just trace their back plate and
              hand it to someone who has the special tools to cut one or
              more out.<br>

                  of possible resources for people trying to piece <br>
                  together an EFI system with a focus for TR3-4A
                  engines.<br>
                  <br>
                  Before TWM went out of business they offered DCOEs,
                  intake manifolds, <br>
                  and major EFI conversion components, including
                  throttle bodies based up <br>
                  the DCOE configuration.<br>
                  <br>
                  When TWM went out of business they sold their EFI
                  business or <br>
                  transformed into Borla Induction<br>
                  <br>
                  <a href="https://www.borlainduction.com"
                    rel="noreferrer" target="_blank"
                    moz-do-not-send="true" class="moz-txt-link-freetext">https://www.borlainduction.com</a><br>
                  <br>
                  Who produces the DCOE based throttle bodies and other
                  major EFI components.<br>
                  <br>
                  TWM sold their intake manifold business to Pierce
                  Manifolds, who still <br>
                  offers the TWM DCOE conversion kit for the TR four.<br>
                  <br>
                  <a
href="https://www.piercemanifolds.com/TRIUMPH_TR3_TR4_HIGH_PORT_WEBER_40_DCOE_p/k131.htm"

                  <br>
                  So you can still get the manifolds, linkage, EFI
                  throttle bodies, <br>
                  position sensors & such, all originally designed
                  to work together as a <br>
                  system.<br>
                  <br>
                  itg makes an air filter with holes properly spaced for
                  the TR four using <br>
                  TWM/Pierce manifolds and DCOEs or TWM/Borla throttle
                  bodies. The <br>
                  critical component is the back plate which I don't
                  think is still being <br>
                  mentioned in their web site. If you want to use a itg
                  air filter (I have <br>
                  one on my TR3 with TWM manifolds & DCOEs) ask for
                  back plate part number <br>
                  28-JC-50.<br>
                  <br>
                  itg has a formula (for their filters only) that
                  calculates the minimum <br>
                  distance between the horn opening and the facing
                  element for no negative <br>
                  affect in air flow. The minimum distance is calculated
                  by dividing the <br>
                  inner diameter of the air horn by four.<br>
                  <br>
                  I think this is probably enough to piece together a
                  mechanical fuel <br>
                  injection system & put an air filter on it. No
                  idea about a computer to <br>
                  add the "E".<br>
