for 250rwkw, can't go past a std AU engine.
Get one with good comp and put new gaskets/seals and it will last for ever. |

Here look. This is me cruising in 3rd gear at 7.8 compression 28 psi.... no lag, no power issues. http://www.youtube.com/watch?v=eIfYHkNR_b0

You would be nuts if you didn't use E85..
Which takes 30Lb+ on 8.8 compression easy.. We're getting a head of ourselves here.. Turbo efficiancy and MAP has to be considered.. Street engines only require 280 rwkw MAX..[12 to 15Lb] If it's being built for road use and race weekends ?? There's about 3 different ways to skin a cat here..
