FORGED PISTON AND RINGS SET 83MM VW 2.5L JETTA MK5 5Cyl + 144MM X 20MM HIGH PERFORMANCE STEEL BASIC CONNECTING ROD SET 7/16"" BOLT (1000HP)

For VW 2.5L Jetta MK5 Nominal bore diameter: 83mm (engine displacement 2.510cc) 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: 29.3mm. Dish volume: 12.7cc Pin offset: 1.10mm. Material: Forged aluminum 4032 T6. Average piston weight (unit, without pin): 329g (11.60 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 VW 2.5L Jetta MK5 – 5pcs set 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 83mm set Contains 01 complete set for 5 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. For AGU TDI AEB 8V 16V engine, and others VW engines with OEM 144mm con rods.- Center to center distance: 144mm (5.669").- Big end size: 50.60mm (1.992").- Small end size: 20mm (0.787").- For up to: 1100hp- SPA 7/16" bolts- Tightening torque: 9 kgfm (65 lbft).- 4340 forged steel.- 655g (23.10 oz) each rod with bolts (there may be variation of up to 10g (0.35 oz) between units).- Set with 5 pieces.- Rougher surface finish.- 1 oil channel at the small end and 1 oil channel at the big end for maximum pin lubrication.All SPA Turbo connecting rods come with CMD Extreme Pressure lubricants.About CMD Extreme Pressure lubricants:- When the operation requires extreme pressure, all ordinary lubricants break down and allow metal-to-metal contact with consequent scoring, frictional heat, work and cutting tool damage.They will not corrode the finest surfaces nor will they mulsify with cooling liquids. But these facts are not the most remarkable feature of CMD lubricants. The truly outstanding property of CMD is its ability to withstand extreme pressures!CMD EXTREME PRESSURE lubricants are regularly used from 40,000 to 50,000 psi.
