Tuned 2.1l Ford Pinto SOHC in anger...
Short clip of a tuned Ford Pinto SOHC engine - bored to 2.1litres, Big
Valve head, ported and polished, match inlet, twin Dellorto DHLA45 carbs,
electronic ignition and a custom Exhaust manifold. This engine made 170bhp on
the rollers at Redline Tuning in Iver, and snapped the propshaft universal
joint like a carrot during a test run - Happy days :).
2.2 Ford SOHC pinto Engine with open pipes - Mk1/Mk2 RS2000 Escort/Cortina Kitcar
2.2ltr ford sohc 'pinto' engine
offset ground crank, diesel rods, cologne v6 cast alloy pistons, teflon
buttons, Burton power rings, stainless steel one-piece inlet & ex., valves
(44.5 & 38mm respectively - wasted stems and inlet seat further narrowed).
Epoxy resin used to improve shape of inlet port - 'Apple port' as per David
Vizzard book specs.
2x Twin 45mm Dellorto DHLAs with (If I remember correctly) 38mm Chokes.
Infact, the specs I followed are available in Des Hammill's book 'How To
Power Tune Ford SOHC 'PINTO' Engines. He gives several examples of motors
including 2-3 set-ups for Pinto engines including 2100cc which is the one I
used. It got the results you see above.
Cylinder Head work has been elaborate and very time consuming (Valve guides
have been ground flush with the roof on both inlet and Exhaust ports).
Exhaust ports enlarged throughout. -
Both in. & ex. throts have neen 'throated' and then blended in upstream
with the rest of the port.
Heavy duty bearings all around including camshaft.
Standard ford factory camshaft & springs used during this video.
Standard points type distributor etc etc..
Mechanical Compression approx 10.8:1 (I used 100octane shell V-power
petrol for my runs).
Standard flywheel had all the available mass machined off to give the
lightest possible unit whilst retaining the most of the strength. It has
five steel dowel + 6x ARP bolts fastening it to the crank.
Crank was machined at halesowen engines (Don't think they do it anymore as
old man retired) then heat treated at laystall crankshafts in Wolverhampton
(different trading name now I think) and also polished at laystall
Diesel rods have seen some machining to get them to fit the crankshaft
(Rods are thicker and longer + a little hevier when standard).
Rods fitted with ARP YB cosworth rod bolts (No nuts).
I spent the best part of 7 years building this engine.
It has been a financial disaster and I would not do it again.
Saying that however, the value of building and running the engine
successfully will most likely reveal itself as the years go by.
I'm pleased you like the video and wish you great results with your
(Dedicated to my uncle).

Building Mk2 Escort rally cars
Past Wyedean Rally winner Dave Jenkins talks about the Mk2 Ford Escort,
made from 1975 to 1980, and its enduring legacy in rallying.
The video coincides with the first Escort Dave Jenkins Motorsport has
built, which took a humble one-time economy car and turned it into a
performance machine with a price tag of more than £100,000.
