PIST-OM-DUR-87.50RXS

 

PIST-OM-DUR-87.50RXS
We also supply the RX version which comes complete with rings for those people who are using a secondhand engine. The pistons will come with the rings unfitted as the rings must be gapped when fitting. Available 87.50mm Bore Set of 4. Also available singly.


Duratec 2.0L Omega piston in display engine
PIST-OM-DUR-88.00XS
The 88.00 version is designed for those who have a secondhand engine that shows some bore wear. We would normally recommend the engine is replaced if any substantial bore wear has occurred due to the thickness of the cast in liners & would only recommend the use of an overbored engine for either road use or engines of a mild state of tune. The pistons will come with the rings unfitted as the rings must be gapped when fitting. Set of 4. Also available singly.
Retro Ford included our Duratec pistons & rods in it's News page in January 2007 issue: Retro Ford January 2007
'SBD has released some goodies for the latest must-have engine, the Duratec. They can now supply high-quality intruder pistons for said engine, which will push the compression ratio right up but can also be machined down to suit your application. Their bore is 87.50mm, they were designed by SBD itself & are produced by Omega to suit both the 2.0 & 2.3 engines. Also pictured is a steel rod which SBD can supply for either the 2.0 or 2.3 engine. The 2.0 rod weighs around 455g & has a centre length of approximately 146mm, the 2.3 weighs around 480g and is around 155mm long. The combined piston & rod assembly is around 90g lighter than the standard setup & so will unleash valuable ponies from that Mondeo engine'
See Frequently Asked Questions for why we do not sell Duratec pistons above 88.00mm

ROD-FD-2.0LDUR-146S
Duratec 2.0L steel rod set. We have designed this rod to replace the standard fragile item, it has a bronze small end bush, which replaces the press-fit version. Ideal for use with our piston. These rods have been tested extensively by ourselves to over 9000rpm on standard crankshaft & over 9500rpm on a steel crankshaft. So beware of cheap imitations!
Weight approx 455g
Centre to centre length approx 146mm

This design of rod has several improvements which benefit the engine. There are two vertical grooves on the side of the rod, this directs the oil spray as it exits the big end vertically upwards towards the pin and the crown of the piston,. This has two benefits, it helps to supply lubricant directly to the gudgeon pin also the cool jet of oil to the underside of the crown of the piston helps to reduce the temperature of the piston itself. On the small end, we have repositioned the oil hole which feeds the small end bush. This is because the one at the top which is normally used effectively weakens the rod itself which increases the possibility of breakage when the rod is brought down by the crankshaft. By moving the oil hole to the side of the rod, there is far more material in this area to help maintain its strength.

Because of the above modifications it is no longer necessary to supply an oil feed through the bearing, even if your bearing still has a hole for the oil jet, it does not reduce its improvement, the hole is simply filled with oil and the pressure in this area is maintained.

Practical Performance Car included our Duratec pistons & rods in their Top Gear section of the January 2007 issue: Practical Performance Car January 2007
'There's a lot of potential wrapped up inside Ford's Duratec HE twin cam. Even in standard form it can make decent power once freed from the restrictive Mondeo management system, but with uprated internals the all-alloy lump can cope with astonishingly high revs and serious bhp. SBD Motorsport have just released lightweight piston and steel rod sets suitable for 2.0 & 2.3-litre engines, shaving 90g off each piston & rod assembly. The pistons are an 87.50mm bore, can be machined to fine-tune compression ratio and accept standard Ford rings. Roads are available in 146mm (2-litre) & 155mm (2.3-litre) lengths'

Slipper pistons & rods

ROD-FD-2.0DUR-152

The new 152 rod has been designed specifically to go with our new 2-litre Duratec slipper piston, it is 6mm longer which has helped to reduce the rod angle which in turn helps to increase the torque. On our high spec engine we saw an increase of 6lbft torque & just reaching 200lbft torque. Due to the smaller pin size on the piston, this has reduced the weight of the small end of the rod which means the rod is actually 12g lighter than our normal Duratec rods. We have also upped the rod bolts to the ARP625+ high spec material to cope with the extra performance.

This design of rod has several improvements which benefit the engine. There are two vertical grooves on the side of the rod, this directs the oil spray as it exits the big end vertically upwards towards the pin and the crown of the piston,. This has two benefits, it helps to supply lubricant directly to the gudgeon pin also the cool jet of oil to the underside of the crown of the piston helps to reduce the temperature of the piston itself.

PIST-OM-DUR-87.50SLS  Forged Duratec slipper pistons

PIST-OM-DUR-87-50SLS

We have designed a 2 ring slipper piston for the 2-litre Duratec with the help of Omega & the latest improvements in design that they have gained through GP bike development, we have produced a new forging specifically for this piston. It is of a much stiffer construction, uses a smaller lighter pin at 18mm, we have also moved the pin closer to the crown of the piston which helps to reduce piston rock which also helps to reduce friction. It is ultra-lightweight & low friction; in initial tests we saw a 7bhp increase in our high spec engine simply by changing the pistons along with new matching rods.
