This is the most interesting stage of the whole project.......
Once it's on the road, the fundamentals of the motor, mapping, timing etc. diminish to some degree. But hey, you got your hands full with it.....and most likely have things to work on besides entertaining pelicanites.
Excellent updates thus far...
Basically...., we're all curious about the powerplant.

As Keith said the motor was built by Timmins and tuned by Peter Dawe.
It has a 993 case, 3.9L displacement, upgraded rods, springs, retainers, solid rockers, ported heads, bigger/lighter valves, ITBS (Jenveys) induction, aggressive cams, Motec M600 ECU.
Peter (very busy as we are in the middle of the racing season) tuned it and was impressed by the torque. He's sending me the dyno sheets but the motor was putting down 310 rwhp at 7,000rpms.
The cams are designed to hit the peak HP at 7,600rpms.
So (very grossly) at 7000rpm the motor is putting down 232.5 ft/lb of torque.
We'll lose some torque but at 7,600 I would think the motor would put down around 330rwhp.
We can talk numbers all day long.. I am not interested much in wether it puts out 375hp or 390hp. To me driveability and throttle response are top....
Plus if Mr Dawe was happy with it.. then I am happy too....
