Wössner Z20 turbo Forged Pistons

Wössner are regarded by Europe’s leading motor sport engine builders as being the piston of choice when building an engine not only to perform, but to withstand the stresses and duress’s of competition life.

Wössner pistons feature a unique Moly coating on the skirts and a grade of 4032 Alloy (T6) which allows the engine builder to run a closer piston to bore tolerance then he might do on another make of piston.

This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances.

The crowns of the pistons are also mirror polished to better resist detonation on a high performance engine. Mirror polishing allows a more even spread of heat inside the chamber which will help prevent “hot spots” on piston crowns. Price includes all piston rings and gudgeon pins.

Z20 oil pump fitting collar

Tired of using a screwdriver to poke the seal over the crank when fitting an oil pump to the Z20 engine ?

Do it the proper way with this fitting collar – this fits over the crank end perfectly and has a taper to the outside , allowing you to line up the flats and then just slide the oil pump onto the block , the professional way

if you have ever managed to damage a seal when building one of these you know that by the time you have stripped it back down to fit a new pump seal , this thing would have already paid for itself 3 times over .

If you build a few Z20s then this is for you , if you want to build one but carefully then hopefully we have made the price accessible.
