Hey i am new to this 4.6 motors. I have a 99 cobra with a vortech SQ blower. My mods are 03 cobra fully forged block, 03 cobra intake cams, spec III clutch. I am wanting to put a turbo on and take the blower off. My question is how hard would it be to turn the stock header around and use them? I did that on my 5.0 for a twin set up. Also do you think I will need a different K memeber to get the 3 inch downpipe though? Thanks.
