oh yes much more involved that that.

Water hoses to modine need extending,
oil pressure switch need moving or theaded block rotating so pressure sensor faces down, which rules out all possibilities of fitting and external oil pressure for a gauge.
Turbo oil feed pipe on 2wd foul on the tank.
Block need's tapping with m4 tap for location bolt (not needed really)
Dipstick tube need bending. (which makes the dipstick foul on the tube internally upon removal)
New bracket needs making to hold dipstick once suitable place has been found.
-8 & -10 fittings need welding onto sump.
sure there is other things ive missing.
Plus my one from Needforspeed had no o ring recess where it sits into the block which there supposed to have.

Then there's the cost
