FWIW
"The engine is a 1641cc flat-4 engine. I recently rebuilt it. It has 87mm forged pistons, Rebuilt conrods, stock crank, MOFOCO 110 cam (equivalent to a scat c25), rebuilt cylinder heads. Redline is around 4750 rpm. This is a strong engine. It has the Megasquirt fuel injection controller. The injectors are Mustang 19 lb/hr rated, the throttle body is off of a 95 ford escort, the turbocharger is off of a 2003 Audi A4. The computer is tuned to run 20 psi should you desire to push it that far. It does have a manual boost controller set to around 10 psi. It is also equipped with a blow off valve for that highly desired WHOOOOOOSH!!!! It is setup as a blow through. The engine is equipped with a MSD Boost Timing Master. It retards the timing under boost and is adjustable. "
