Cosworth head on a pinto
Just wondering is any one is running a 2ltr pinto with a cosworth head on it. If so what kind of output are you getting. I would be using my 45
dellortos on it. Also what do these setups use fuel wise, cos with the 1500 mile round trip to Le Mans next year in the tiger fuel might get a little
costly. My current pinto does 100 miles to the tank about 20mpg

I've not got one, so happy to be corrected, but my understanding is that a 2 litre Pinto with a Cosworth head pretty much *is* a Cosworth motor
(though not as strong).
If as you imply, you go naturally aspirated then 200-250ish bhp should be possible with the right work. I recently heard of one running with Weber
50's with lots of porting, bigger valves, and race cams that made 315bhp on a stroked 2.4 bottom end.
But, I don't think this is a particularly cheap or straight-forward option ... its not just a simple head swap. I think you'd need to do
work on both the head and on the bottom end to make it work, and then continue to work ...
Fuel economy will mainly depend on the right-hand pedal, as always. Tootle along at 60mph in a high gear and you'll maybe see low 30's.
Thrash it and you'll see low teens (possibly less!)
Hope that helps

I heard a long time agao that the reason the cossy lump was so good was the turbo was a perfect match to the set up and that the head wasn't
that special, this was also about the time the Warrior head was the better one to get, not sure if things changed/become clearer over time

It would need a change of pistons and cams, the porting is restrictive for a NA engine and requires a lot of work to bring it up to standard, and when
you have spent all that money it will use fuel at a fantastic rate. Nice engine if done right, but not a project to be done on the cheap, you'd
be better off using a Zetec engine, as this would provide you with a much better starting point.
Whatever you stick the twin 45s on will use lots of fuel, it's the nature of the beast.

Incidentally, this sounds a little low. My original (standard) 2litre pinto made upper 20's in a Super Six, with no problem. When I swapped to
mapped ignition I was regularly seeing low-mid 30s. But then maybe I'm just a wuss of a driver

I find these fuel consumption figures hard to believe, I used to own a Mk 3 cortina which had a 2ltr pinto, and that regularly turned out 25 plus to
the gallon. I would have thought that fitting that engine, (even tuned), into a car that wieghed just a bit over a bag of sugar, you would get up into
the high 30's. Mind you if you wear size ten lead boots, then maybe not, but even then low 30's.

Mine gets about 23mpg on general blatting about (full throttle 50% of the time, full brakes the other 50%), but if I take the Mrs out (knuckles go
white at anything over 50mph), I can easily get over 50mpg, and over 65mpg on one occasion, but I get about 45mpg on long trips.
2.0 Pinto injection.
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Better off now going for a Duratec as they are ali blocked and produce 200bhp out of the box. The Cosworth head was designed for forced induction and
therefore not great in standard form if used as a n.a. lump. Millington Racing Engines have for some years built unit called the Diamond, bored out to
about 2400cc and producing summat like 300-350bhp ( I think) but costing upwards of £10,000-ish. Nice Duratec or Zetec I'd go for.

The low fuel figures is probably a lot to do with the twin weber 45's that are usually fitted to these engine, they don't really have jets
in them, rather funnels!!

millington was developed in the late 80s early 90s , extensively used in darrians .
the 2.5 version was over £14k on carbs .
obviously you get a new engine for that - its just not worth spending that money .
unless you can pick a previously converted engine . Cosworth also made some big port castings , but mainly to sell to people building them .
a duratec would be fine

Cosworth heads were designed from the outset to be turbocharged. I think they have low port velocity or *something*
Back in the late 80's if you wanted to soup up your n/a pinto, the Warrior 16v head was the one to have as it was designed for normally
aspirated engines.
At least, that's what the voices in my head are telling me.
Cheers,
Neil.

Originally the cosworth engine was born from cosworth building a 16 valve head conversion for the 2.0 pinto for engine tuners to use.
Ford upon visiting the factory thought we could use that and said build us an engine! Cosworth had plans of making it 250hp n/a with big carbs but
ford wated a turbo however.
A chap i know has a pugeot 205 rally car with a rwd n/a cosworth engine, this produces 250hp i believe with twin 48mm carbs.
If you want a n/a cosworth engine buy a blown YB, either head gasget failure or melted pistons, perfect opportunity to make a stronger engine then.
pistons i believe for n/a use are 96 ex vat a piece. i think the whole engine could be done for under 1000 if you took your time and shopped around.
