max power from a 1.8t

[Wayne]

Stroker engines for sale online at £8k and a good GT30 kit for £2400 then your front mount,fuelling, intake, sensors, manifolds, piping, labour costs say £5-6k not including engine mounts, clutch, drive shafts, wheels, tyres, diff, mapping, exhaust, then correct brakes and suspension.....£5k again?

450bhp easy.

For that much money you could just buy a quicker car
