Go for a 4x4
standard might be an idea if you want to get used to the power but you will soon need more and get bored i can guarantee you.
getting stage 3 does add up when you take a new turbo into account.
you would save £'ssssssss if you bought one that had already got it done (properly). then u can just take it easy for a while until you get used to it
Also, 350bhp in my 4x4 is less scary than an old 200sx s13 i used to have with 170bhp.
