Forged flat top piston and rings set 83.5mm VW 2.0L 8V + Application solid tappets performance camshaft

Forged flat top piston and rings set 83.5mm VW 2.0L 8V For VW 827 2.0 8V engines won’t fit ABA, AGG, or other tall blocks. Nominal bore diameter: 83,5mm (increase engine displacement to 2032,69cc) Recommended bore to piston to bore clearance: 0.08mm (For nitrous or extreme applications, consult your builder) Piston ring grooves: 1.5 mm / 1.5 mm / 2.0mm Compression height: 29,30mm. Pin offset: 1.10mm. Material: Forged aluminum 4032 T6. Average piston weight (unit, without pin): 318g (11,21 oz). Rated for 1000hp. Innovative high performance piston skirt design that provides: 1. Smaller piston to bore clearance  2. Less noise 3. Better ring seal 4. Higher power 5. Durability Features: Anti detonation grooves: protect the top ring by disrupting detonation waves and reduce piston-cylinder contact in high temperatures and engine RPM conditions. Accumulator groove: accumulates residual combustion gasses reducing top ring flutter and improving seal. Pin oil lubrication by broaches and oiler to reduce friction and increase durability. Super A Piston Pin for VW827 (63.45mm) – 4pcs set For VW 827 engines (Super A pistons) Dimensions: 63.45mm x 20mm (length x O.D.) Average unit weight: 116g (4.09 oz) Rated for 1.000hp Made from special steel alloys that combines optimal mass with high resistance.   Piston rings 83,5mm set   Contains 01 complete set for 4 cylinder engine.Compatible with SPA Super A, with 1.5mm / 1.5mm and 2mm channels.Ring thickness:1st ring 1.5mm - Made of carbon steel, which is 35% more resistant than cast iron and on average 30% lighter. With DLC (Diamond-Like Carbon) treatment, which is the application of carbon particles, whose physical and chemical properties are very close to those of the diamond, providing greater resistance to the material and reducing the friction of the surface, which significantly reduces friction when working against other surfaces.2nd ring 1.5mm - Made of cast iron.3rd ring 2.0mm - Manufactured in 3 pieces, which guarantees easy maintenance, better stability in the control of the oil film and improves the oil removal through the piston lubrication holes, as it has a better area for displacing this oil.   VW 8V 288 N/A application solid tappets performance camshaft   Application: EA 827 engines Capacities 1781-1847-1984cc from 19868V Engines with hydraulic tappetsVW Golf, Corrado, Audi 80, 100, 5000, Quattro, Jetta, Passat, Scirocco, Sharon, Vento, Gol, Pointer, Saveiro.
