The SWR (Sunworld racing) engine oil pump has up to 40% faster flow rate than standard. If you have a big bore kit installed or other race performance parts installed, it is advisable to replace the internal engine oil pump to a high flow unit. The higher rate of engine oil flow will help cooling and reliability.
