03-05 Evolution VIII Toda Racing Exhaust Campulleys
TODA Racing Adjustable Campulleys allow precise tuning of camshaft timing. Adjustable campulleys are essential when using TODA camshafts or any non-stock performance camshaft.
TODA campulleys are made completely from T-6 7075 Duraluminium which is a more expensive and it's a higher grade of aluminum commonly found on fighter aircraft landing gear or other high stress areas. Unlike our competitors which generally use T-6 6061 aluminum, which is the least expensive but most versatile heat treatable aluminum. Since T-6 6061 is more versatile, it might require more attention in a long period of time. The use of T-6 7075 aluminum allows TODA Racing to offer the strongest and lightest campulley on the market.
In addition, our advanced "VERNIER" timing degree system makes TODA campulleys 50% more accurate than our competitors. VERNIER timing degree system measures crankshaft degrees, not camshaft degrees. For long term durability the timing marks are machined into the metal, not painted on, or silk screened, therefore they will not rub off with age.
SR20DE(T) campulleys utilize stock factory steel outer gear and aluminum adjustable inner plate. First used in JGTC (Japanese GT Championship) number 81 Daishin Silvia. TODA JGTC SR20DET engine won the construction title in 2001.
TODA 4G63T campulleys are compatible with all Lancer Evolution models (EVO I~EVO VIII) without MIVEC (Mitsubishi Innovative Valve Timing Electronic Control System) function. Intake and Exhaust campulleys are interchangeable.
