Consider that the factory achieved more than that for their
SuperProduction (euro series) Cars. Rumor says 400 HP.
I've assumed that 400HP needs more exotic pistons, rods, and crank but
280-300 may work with stock stuff.
A lot of this is detailed on my "page" but here's a little more detail.
(copycats welcome!)
Here's the steps I intend to take to get there...
Breathing (other than turbo itself):
- Danielson Stage I head which has bigger valves and is ported
- Extrudehoned intake manifold and plenum
- bored throttle body
- smoothed ducting/hoses
Intercooler:
- air/water to improve soaking and latency limits
- large radiator in place of muffler with ice chest in trunk
- electric pump for constant circulation
Turbocharger:
- T03/04 hybrid with ceramic bearings
ECU and Boost Controls:
- standard N9TE ECU
- Saab APC system for 1+ bar boost
Exhaust:
- full 3 inch (almost) from turbo to side exit exhaust
Ignition:
MSD 6A for sure spark at high boost
Injectors:
- N9TEA (or larger) injector
Fuel Pressure Control:
- Malpassi (FSE) Rising Rate
Other:
- thermal insulation on various ducting
