I'm a big fan of the Crossflow engine, ultra reliable, will stand a fair amount of neglect and abuse too. Easily tuned to up to about 130 bhp but after that you are into big money or Zetec engine swaps. Can have the engine swapped in 1hr 30 mins.

Don't write off the CVH engined cars nor the FIAT engined ones too.

When I put my TR engined Plus 4 on the road last year, it took a bit of getting used to compared to the 4/4.
