yes grant, you should go for more power, the car looks nice as it is. I certainly like it as you well know. please ignore my previous suggestion listed above as its quite ridiculous actually when i think about it.
reckon getting the engine swapped out for something like a 2.5 block with the mods you have could make it even better.
i dont know what scooby andys talking about? my inlfatable goat mounted intercooler works well for me
