Ford 2litre (pinto) engine

Ford 2litre (pinto) engine

Ford 2litre (pinto) engine

(OP)
I was asked the question about the viability of a 2litre ford engine if turbo'd for a rally car.I have my doubts with the crank and was wondering if anyone has modified these engines previously and what problems they encountered.

If only somebody would invent a way of searching the internet. They could call it goggle, I bet it would be worth a mint.

Cosworth YB.

RE: Ford 2litre (pinto) engine

Pretty decent engine. Similer to 2.3 pinto which was an out growth of that basic design. Rod bolts are smallish won't live long beyond 7 grand rpm. Other then that you should be able to push 300+ horse through it without too much trouble. Just a thought, why not one of the other offerings that are all aluminum or iron block aluminum head. 4 valves per cylinder. The 2.0 you are considering seems a little clunky by comparison.------Phil

RE: Ford 2litre (pinto) engine

I modified one of those engines, but kept it NA.  Balanced the stock crank and rods with forged aftermarket pistons.  Big cam (0.5" lift, don't recall the duration).  Ran it past 7500 during a number of autocrosses to avoid an upshift-downshift sequence with no internal problems.  Went past 6000 on a regular basis.  

What I did find was that timing belt longevity was greatly reduced when forced to operate the necessarily stiffer valve springs.  And even after a careful build it still seemed to use as much oil as it did when it was 100% stock.

At one point, there was a 4-valve head available for this engine through Ford, though it's almost certainly out of production by now.

Spearco and others had turbo kits for this engine, though most of the publicity for same was dragstrip related rather than road race or rally.

I, too, did one of the T Coupe 2.3's  back in the 80's.  I used SVO cams and roller rockers, Isky valve springs and I ported the head and manifolds (I used the cast iron exhaust manifold heavily ported and matched) and modified the waste gate to allow 18 psi boost (Bosch adjustable fuel pressure reg).  The engine made 290 hp at the wheels on the chassis dyno and would top 155+ at El Mirage with the stock rev limiter.  I always felt the engine was being stifled at the sub 6000 rev limit.  Most of these engines love to rev and seeing them at 9000 rpm is common.  The bottom end of the Turbo Coupe version is bullet proof. One good thing, parts are readily available as these engines are raced all over the world (Google, my friend) and should you break a cam belt, no harm, no foul (at least on the 8.5 CR version turbo) the valves won't hit the pistons.

RE: Ford 2litre (pinto) engine

Some of these engines were turboed from the factory.
They are used in stock car racing  in my areas and those guys turn them over 8000 rpm in modified form.
Ford motor sports sells variations of these engines and I believe there are used in Formula class racing or one of the entrance classes.

Thanks to all for some good info.The crank was my main issue but I got much more advice than I bargained for and is much appreciated.Keep up the good work.

RE: Ford 2litre (pinto) engine

Have you bothered to check out "Esslinger Engr."?  They are pretty much the gurus on this engine.
