is there a differance between a series 1 and 2 engine, the reason i asked is the original engine in my series 2 went bang and i installed an engine i had spare from when i had my xr3i (bought, was gonna drop it into the 3i but lost interest and bought a real rs.) i decided to fit a new cambelt and water pump but the water pump on my original engine is totally differant to the one on the spare. the original wter pump has one outlet and the spare one has 2 will post puics tonight to make description easier. any help appreciated
