If you were talking 16V then you could save yourself a whack of ££'s as I notice from your sig your in the states atm.

You could have yourself a pukka bottom end by using the Blacktop engine thats used in the 2.0 Focus out there & here in the UK. Source the Rods, Pistons when you are out there, to lower the compression, so its ready to take decent boost.

The Blacktop will cost you a bit of extra cash in the UK but is a far superior engine than the earlier 2.0ZT 16v's.

You would see 300bhp without having to touch the head( bonus )
You would still be talking about Management.
Can use EFI inlet & RST manifolds with adaption.
T34 would be ideal.

I supose it all depends whether you want to carry out the work yourself or have a UK tuner spec things for you, but IMO you could walk away with a 300bhp engine with the potential for a whole load more, whilst keeping costs lowish.
