Its not that straight with too many things needing changing or upgrading.

But the biggies are :-

Engine, gearbox, rear diff, ecu, loom, brakes and suspension.

It's 20 pages so is doable but a hell of a lot of work.

If you fit a turbo your insurance would end up the same as a WRX or worse as it's then a modded car & not a standard one.
