Having got my hands on the S4, I can't wait to start tinkering. Because of budgetary constraints, I think I will follow Andrew's advice and go for a 38 DGAS. I have found one on an RS2000 manifold. Will this manifold bolt straight on to the Pinto?
I also read somewhere that an RS2000 exhaust manifold would be an improvement. I have also found one of those for about £40. Likewise will this bolt staight on? I realise I'd need to modify if for side exit.
