DIY throttle bodies and manifold for Pinto
I'm afraid I have no idea who converted these,
or what carbs were used, there are no markings left on them whatsoever.
They are converted 40mm carbs, powder coated,
with modified spindle to operate the tps, which is on a bracket
at one end. Fitted with alloy torque tubes and chromed steel ram
pipes and mounted on to a fabricated Pinto manifold, which is powder
coated. The fuel injectors (I'm told 1600 Vauxhall) are mounted
into bosses in the manifold (not the bodies), and fitted with a
fabricated alloy fuel rail.
They do look remarkably similar to a set in Dave
Walkers injection book though, even down to the TPS.
All fixings are chromed steel, as is the TPS bracket.
There is a vacuum connection on the underside of the left intake
tube, and an untapped boss on the underside of the right intake
tube. The centre of the manifold has a fitting for what I assume
is a water connection. The torque tubes are alloy, 58 mm in length,
the ram pipes are 42.5 mm from the front face to the torque tubes.
The bore of the bodies is 40mm, as no chokes are fitted (obviously,
but you'd be surprised the number of people have asked).
The TPS has been removed to show the D shaped spindle
The manifold is powder coated alloy, 93mm at the
top face, 73mm at the bottom, so you should be able to work out
the angle from that if necessary. All faces are skimmed flat and
free of coating. Two locating dowels are fitted, between tubes 1-2
and 3-4. The injector bosses are ground flush with bore of the tubes.
Doesn't show up very well, but there is a linkage,
consisting of two sperical bearings. One LH thread, one RHthread,
with a threaded adjuster between them.
