Only real restriction is that I want to stay rotary.
assuming you stay rotary. the most reliable way, is the simplest. ideally you'd start with a running factory turbo car. the engine needs to be rebuilt with new rotors and probably all 5 housings. maybe a small street port, less is more here.
you need to replace ALL of the water hoses, radiator, water pump, thermostat, thermostat neck if its an S5.
you need a 3" exhaust, bigger fuel pump, larger injectors (550/1600 or since the EV14's are in fashion maybe 700/1000). you could do 300hp on a BNR style hybrid, but a 60-1 on an HKS manifold will do it with less boost. you need an intercooler, a good efficient core can be smaller than a cheap chinese one. in fact the JDM 1.5 stock intercoolers actually works quite well.
you need a good ecu, PFC for instance. tune it well and leave it alone!
i did one that was a new engine, except the Eshaft, 60-1, and after 10,000miles of street use it did 392rwhp@12psi....
