Rotating Assembly της ZRP για Mitsubishi 4G63 / 4G63T με μπιέλες 156mm
Mitsubishi EVO 4G63 / 4G63T ROTATING ASSEMBLY (Comp.Ratio 8.5:1)
This ZRP kit for the Mitsubishi 4G63 engine is the ultimate solution for taking this engine to the next level of performance tuning for racers that can’t exceed the 2.0L barrier but can benefit the broader torque and horsepower band. The Rotating Assembly kit utilizes an 88.00mm stroke crankshaft, ZRP Heavy Duty (EN24) Series Long Connecting rods 156.00mm and custom made Wossner forged pistons.
The crankshaft is manufactured from 4340 High Tensile Billet Steel, designed from scratch, with knife edged counterweights and straight through oil feeding, to reduce weight and rotating mass while providing enhanced lubrication. The result is very light, yet tough enough crankshaft, that is able to handle power outputs in excess of 1000ps.
The ZRP heavy Duty (EN24) rods, are designed with maximum power in mind. They are “I-beam” shaped and made from the finest materials, High tensile steel 4340 EN24T-817M40T. They are equipped with ARP L19 3/8 fasteners. For pistons, we have developed with Wossner a new line of “beefed up” pistons to accompany our kits. They are based on trustworthy forgings but have special hardening processes, designed to accept oversize valves and high lift cams, 3.20mm skirt walls, lateral gas porting, heavy duty pins and premium quality rings.
LONG RODS Benefits:
Allows for higher compression ratios (or boost pressure)- Reduces the tensile loading of the rod (nr.1 cause of rod failure)
- Reduces the pulsing of the intake charge and provides a smoother flow
- Reduces peak piston speed
- Increases the peak airflow
- Allows for shorter piston skirts
- Reduces piston rock and aid ring seal
- Reduces piston side loading for less friction and less bore wear
The Rotating Assembly Kit includes the following:
- ZRP 4340 Billet Steel Crankshaft with knife edged counterweights.
- ZRP EN24T-817M40T Forged steel I-Beam rods w/ARP L19 fasteners
- Wossner custom made pistons with Gas-porting
- Heavy Duty wrist pins (Cylindrical shape)
- Stainless chrome/Ductile moly top rings, tapered second ring, 3-piece oil rings
- Piston clips
- Fully system balanced and ready to install
Great horsepower and torque gains.
