Call me Mister Thickie but there were a few things i wanted to know about 2.0litre DOHC pinto engines. What are the main differences and what are common problems/issues when using an injection version as opposed to a carburetor when including them in a kit car such as an Mk indy.

Thanks for any help

carb version is 105hp efi is 115hp.

you will find the efi sticks up a fair way above bonnet line.

mark allanson has made a modified system - might be pics in his archive, or u2u him

DOHC or pinto?

different engines.

Cheers

The DOHC and pinto are different engines. A search of this site will yield plenty of information. The DOHC was around 125bhp and even heavier than the pinto at 115 as Steve said. Mark's solution to getting the plenum system under the bonnet looks a good one. Once again there's been plenty of chat, which can help you decide which way to go. Many of the carb installations that I have seen haven't quite fitted under the bonnet though.

I did an injection one by modifying the standard unit, Photos in Cairb.

Hope this helps.

Cheers,

Colin

Thanks for the replies and i meant DOHC not pinto now you mention it

I missed the fine detail and my answer referred to the pinto!

125 hp for the dohc, and similar tall bonnet issues

See also previous discusions on twincam reliabilty problems. Nuff said.



Enjoy

The twin cam reliability was not really its fault. We tend to get them out of 'end of life' cars when they have not been correctly serviced. They need regular oil and filter changes, and chains at the specified times.

What I am trying to say is that it is a good engine, but won't take the abuse like a pinto can

What is the specified time?. When the bro in law had one we couldn't find a service interval for the timing chain.

I have seen 60k as typical for the cars I have had

Here we go again.....From my experiance the Ford DOHC 2.0i engine is one of Fords better attempts.....It's BULKY but not massive.

It can go into a standard locost with a few mods........Take a look here:-

..& here is someone whos doing it:-

After you pass SVA you can always change the engine for a newer ford lump...It just needs to be addapted to the MT gear box....not a majour problem.

p.s. my daily drive is a 2.0i sierra....

the reason you cannot find a chain change interval for this engine is that Ford didn't specify one, but the accepted norm is that it is worth doing at 80000, and that they have a tendency to break at 120000 miles, usually due to the tensioner running out of travel due to chain stretch/wear.

The ford service manual states

'The timing chain must be replaced at least 2 weeks before it breaks....'

See, that's all we were looking for, some definite advice, it wasn't asking too much was it?. Now where's my crystal ball and sockets.

Yawn..........seems the main reason the timing chain goes is the use of the wrong oil.....should be 10/40 & not 20/50....helps if you don't thrash the engine from cold (but no one here would do that anyway?)......too thick on startup when it's cold. this causes the hydraulic chain tensioner to place too much tension in the chain & Pop!

If you would like to read a little more on ford engines:-

....Ohh & the MT75 gearbox DOES NOT use 80EP oil.....so If your gear change is a little stiff....you may like to try the propper oil.....best changed before installing the box.

I'm cross-posting this so we can get some better info.........

I'd rather be laughed at for being a fool.... than be a laughing idiot.........
