Hey everyone,
I'm new to all this, just after help or advice on what I can do to make my 03 BA future a little bit quicker.
I can't find much around so I'm assuming it's a little harder to upgrade a naturally aspirated 6 cylinder.
But any help would be appreciated!

Just the usual stuff, a cam and tune, decent valve springs, good extractors and exhaust, 3.45 or shorter diff gears, that sort of stuff. Plenty of stuff on here about that.

Or just find a wrecked XR6 Turbo and do a transplant.
