You're doing a great job there, but I have to take issue with your assessment of the original engine!!
I don't think Buddsy was being sarcastic, the 900 series is a corking piece of engineering.... as is the Rover V8 (I've built dozens of em).
But I think most Esprit fans would agree the revvy 4 cyl engine is more suited to the car than the lazy RV8..... nonetheless, opinions are like bellybuttons: we've all got one.
Try not to take the comments too personally, you're clearly doing an ace job...... even if it's wrong
