Lexman

I wonder what the difference is between the N / A and the turbo engine? The idea is to switch to Forged Pistons & H-Beam Connecting Rods. but is there anything else that separates them in blocks and tops? Then the problem is that I live in Sweden and here are not these engines to get hold of, so is there anybody who can help send them to Sweden? any company or someone who sells them and can ship abroad?
