Nor will ever be.
The crank casings are all much the same, so:
Option 1) 3.3 turbo pistons, rings, bearings.
Or
Option 2) 3.6 crank, rods, bearings, pistons, cylinder casings.
Or
Option 3) 3.8RS crank, rods, bearings, pistons, cylinder casings.
The last two are going towards being a n/a build, although option 2) can be changed to a turbo spec build for much the same price.
1 and 2 we can keep the bigger cams already in it, so its a bit more cost effective. The 3.3 turbo options is more realistic in terms of power wanted VS cost, so it'll prob go that way.
It's getting a chip done soon for the new exhaust an cams, so dad/me will just run it until it brakes something then think more about it.
