So in that case.... what would the power limit be while retaining the stock intake, exhaust manifolds, and exhaust header pipe? Maybe 200-225hp? I think few people have the capability to install custom headers and custom exhausts - "bolt on" stuff is much easier to work with. (Yeah, I know we can't get 300-400hp with bolt ons, but I'll worry about those power levels *after* I get to 180-200hp!  )

THere are T3/T4 hybrids (T3 exhaust turbine with T4 compressor) then there are various Trim levels that will get you higher flow at top end with less intake charge heating....but at cost of low speed spoolup.
Unless somebody at Cometic (#1 head gasket supplier in the Turbo sport and compact world) can do custom head gaskets for the 617 and head studs on head boost levels are still gonna be under 15 psi. Custom pistons allowing 18-1 compression will allow higher boost levels and more fueling for more power but now you are talking far more money than most of these cars are worth, even the nice ones......
