<p>Only as a last possibility. I'm working on 3 projects that are
taking all my time & energy. If you have a way to get them
produced in hand & no other source for a pattern, I can remove
mine, go out & buy a big sheet of paper, trace it then mail
you the tracing. I expect to have more time in a couple months.</p>

</div>
<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"
rel="noreferrer" target="_blank"
moz-do-not-send="true" class="moz-txt-link-freetext">https://www.piercemanifolds.com/TRIUMPH_TR3_TR4_HIGH_PORT_WEBER_40_DCOE_p/k131.htm</a><br>
<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>
