With the factory valve seats, the typical life of the 2. Beware of systems with huge pipe diameters though - they are not necessary and hurt power. However, the cam is very easy to change and not expensive so I tend to treat it as a service item like brakes or tyres - a new cam and followers every couple of years and all is well again. . The standard casting has a plain flat finish to the external sides of the head. It now used split port induction and produced 110 hp 82 kW and 125 ft·lbf 170 Nm.
Extra capacity on its own does relatively little for power until cylinder head flow and cam lift have been improved in proportion. Even today, some 20 years after its release, new ways are being developed to extract even more performance. The additional displacement was achieved by boring the 1. It offered a negligible improvement in terms of either performance or economy over the older Kent engine which was cheaper to manufacture, hence the 1. Chris has been using his car as a road car and for run- what- you- brung drag racing.
It was later used in the as well as the and from 1983 it was used in the. This engine is also a non-interference design. I have my own valves made and offer 43. This stroke length would be used in the 2. As above, a short motor for home assembly starts at £, please phone for more details. Bore was now 82 mm 3.
Lubricate inside with oil and tap gently into place on the valve guide with a small socket or length of tube. With the factory valve seats, the typical life of the 2. Chris Todd has made some radical changes to his Mk 1 Fiesta, not least of which is putting the engine in the back! It includes spring caps machined to locate the inner spring properly and requires your old caps on exchange. The exhaust valves are actually far too big as standard. Bore and stroke were now 82 mm × 88 mm 3. However, they also tend to have very bad port shapes and can't be modified for good flow or you'll break into a waterway. In reality it only develops about 105 to 110 bhp.
In South Africa, the 1. When I build a fast road engine I put the necessary cutouts in anyway in case a big valve head is added at a later date. Output was 69 hp 52 kW and 86 ft·lbf 117 Nm , while European versions produced 90 hp 67 kW in standard carburettor trim, or 105 hp 78 kW , 108 hp 81 kW or 115 hp 86 kW in various fuel injected versions. The only proper solution for high rpm engines is correctly designed double springs like our own. Best avoided even for ported standard valve work and absolutely no good for big valves.
The springs aren't located correctly and usually either the inner or outer spring goes coilbound long before the other one. All new core plugs fitted. Bore was 80 mm 3. Somewhat surprisingly, four-speed Escort Pony models achieved better mileage than five-speed cars, with upwards of 30 mpg in city driving and 40-45 mpg on the highway not uncommon. The new lifters will be reduced to scrap by the worn cam lobes within minutes of starting the engine.
Its valves were mounted at a compound angle in , although some versions altered the combustion chamber shape to increase swirl. To compound the matter, Ford didn't use the best available material for the camshafts. A short motor ready to accept all 1. However, the 1300 was dropped in 1986 and replaced with a 1392 1400. The 1800 has a very poor flowing cylinder head designed for swirl and economy rather than power - also the camshaft is a roller follower design and quite different to the smaller engines - for these reasons the 1800 is not considered a suitable engine for tuning.
The engine is so simple that it's pretty hard to assemble it wrong but despite this the one thing that few people get right is fitting the oil pump. The block was slightly modified to provide an oil return from the turbocharger. The cylinder head is capable of very high flow figures when correctly modified and the power capability is good. In 1700 cc form I have an engine to that spec with a solid 140 bhp plus doing the rounds of the dragstrips in Aberdeen which shows a clean pair of heels to 16 valve Golfs and Vauxhalls and the like. Change the oil and filter too flush the engine out as well if you want to do the job properly - all that material that wore off the old cam lobes is down in the sump gradually wrecking the crank bearings and oil pump. Early Mk5 Escorts carried the engine but it was phased out in favour of the Zetec.
