engine overhaul 120-130

The exhaust with the dual downpipes makes a huge difference to the way the motor produces power. I did this conversion on the B18 engine in a 122S and was surprised how the engine seemed to deliver better performance. I have also done this with the B20 engine. Using a 2-2.25" diameter exhaust system is important as the original 120 exhaust is restricting.
As I stated elsewhere, the only thing you have to do is somehow match the differing thichness of the inlet and exhaust manifolds.
