Valve springs

Uprated Mazda beehive springs. These are for use with 7500 rpm engines with a max cam lift of 11 mm and will use the standard retainers. Price for 8: £80

These are mainly used to bring early 7000rpm engines up to the later 7500 spec. Useful if you race a stock 2.0.

Uprated valve springs, for up to 8500 rpm and 12mm lift, the price is for 8 springs and retainers as the original retainer is too long and does not fit these springs £160

Updated crank mounted chain pulley with grooved or serrated mounting faces to prevent slipping, genuine Ford part. Do not fit this with diamond washers £50

Genuine Ford timing chain £80

Underdrive pulley £173

The OE pulley weighs nearly 2kg, this one weighs 720g and is a smaller diameter so the water pump and alternator run at a sensible speed at high rpm. This is for track use only and for engines which spend most of their time between 4000 and 8500 rpm. Using the standard item over-spins the driven components in this rev range reducing their effectiveness and sapping power.
