It was a genuine question. The difference between a 325 and a 330 isn't £13k either is it?.

What whp are you hoping to run? Have you included the cost of a remap to utilise the changes you want to make to your inlet manifold?

What is your ultimate goal?

You might get more help in the BMW general forum too.

Well i was hoping to to take it upto the power of the 330i which is 268 bhp i think and then a further remap if possible i know its going to be a few hundred pound for the remap alone.thsnks for the replys
