Wasn't the RS2 was based on Audi's inline 5 cylinder, single turbo? Porsche help develope the RS2 platform. This was several years ago btw. Now it could be a currant S4 Avant which has the twin turbo V6. 250 HP stock. They do make an RS4 (still not available in the US:( with 380 HP stock! Consider yourself lucky Keepsake. You are exposed to cars in your country that we can only daydream about here.
