Quick Overview

The 4 Piston Racing K20C1 Crate Engine is designed to be a more durable and more powerful engine than the OEM K20C1. The OEM connecting rods are strained with increased torque loads and bend easily with the power that is able to be produced by the stock turbo and fuel system. Our engine replaces those with a forged Saenz I-beam connecting rod that is 100 grams lighter than stock, yet can handle more than double the torque and horsepower. The OEM piston is replaced with a heavy duty forged Wiseco piston with tool steel wrist pin. It has a thicker top, thicker pin boss area, and much stronger ring lands, which have been prone to breakage in road race engines. Compression is left close to OEM for easy tuning on pump gas. ACL race bearings are used, and engine clearances are setup for use with racing oils made to operate in high heat strenuous track conditions. The engine can also be daily driven, and expect it to be more durable than the OEM engine.

The engine uses a 4P CNC ported cylinder head, offering up to 130 CFM gained over the OEM tumble port design. The exhaust is ported in the short turn, bowl area, and at the exhaust outlet for increased flow, but left thick in areas where water is near the port to avoid cracking with high exhaust temperatures. Horsepower gains are seen on the stock turbo, but REALLY come to life when using a larger turbo. The exhaust relieves backpressure that you will find once larger turbos are pushed hard for high horsepower. We install Ferrea Competition Plus valves for the high exhaust temperatures. A normal stainless steel valve will begin to distort and bend with high exhaust temperatures, and when they cool they will stay bent. A Ferrea Comp Plus valve has memory....it takes more heat to distort them, but they will also return to their original shape as they cool. High temp Viton valve seals are used throughout, and valve motion is controlled by Ferrea PAC valve springs with Titanium retainers. This eliminated valve float beyond 7000 rpm that exists in the OEM valvetrain. Valve motion is controlled beyond 9000 rpm, and larger camshafts are able to be used with these springs IF you have the fuel system and turbo to support such RPM.
