good article... that motor made 500HP at the flywheel.. it would make a bit less to the wheels obviously, and IMO would not be what i consider reliable.
and also still not a stock block...important notes:
With a goal of 500 hp, forged pistons become mandatory. While B-series pistons are by no means inferior, cast metal is what it is and just can't put up with the cylinder pressures associated with 500 hp-despite the tuning. Placing confidence in the remainder of the factory components is easy but previous testing has shown that
the factory cast P30 pistons tend to fail well before the 500hp mark.
A set of Arias pistons were employed and tied to the factory B16A connecting rods. The Arias pistons feature a flat-top
design that lowers the compression ratio to 9.0:1.
the idea to use aftermarket head studs was tossed aside and, instead, the
factory head bolts that had been through countless torque cycles were used, along with a factory head gasket.
Obviously, this is not the way to properly build a serious turbo engine but it goes a long way toward demonstrating just how strong the stock stuff really is
