lol :up: the temptation ... it's always difficult to stick to the original simple idea along the way isn't it? :lmao:James, i do have an engine which i got a bit over-enthusiastic with and completely stripped it. Now instead of rebuilding it for when the car is ready to be tested, i'll get another V6 to use instead. This way i can rebuild my spare V6 with some slightly different, slightly more expensive parts. Also if i get another F25 with it, i could have a standard gearbox for road use, and a quaiffe ATB diff in the other gearbox for track use.
