So here are some engine pictures. It's a 2.5 SOHC 16 valve with what John at Outfront calls a Z-head modification. If you look at the manifold you can see the intake risers are taller and larger than normal. The 3rd picture is of a normal 2.5 SOHC so you can see the difference. The change is supposedly worth 15-25 ponies depending on intake, exhaust, etc. Once the car is finished Greg will bring it back to Outfront and they will dyno-tune it and we'll see what we have at the wheels.
