port your wastegate, port match the manifold to the turbo inlet, if you rebuild then street port it and use fd corner seals and springs and oil pressure regulator, remove emmissions. I don't know just some ideas. good luck

not really an upgrade, but you might want to check the condition of all your brake and fuel lines.

1) How much power you want to make?
2) How much money you willing to spend?

i'm willing to spend at least 2k on it. now the brake lines are ss and the fuel pump and lines will proly be in that 2k investment. as for rotaryrocket's reply thanks, i mean i would do all of that if there was a shop in my country that actually knows what a rotary is and how to care for it. i know how to care for it because my dad used to own 2 rotaries R100 and a SA22 12AT. i would like to make around 220 - 230 at the wheels, or more if possible with that investment...it has to be streetable nothing extreme.

bump...ok so far i've got the exhaust system (single n1 cat) and a KN cone air intake...i dunno if i should get the dp though. i was gonna start with the simple stuff first like a Greddy Auto Timer and some gauges. cause i have no idea if the dp will get me into the Fuel cut zone, proly will. so then after that i would buy the dp and the FCD. after that i'm gonna get the Walbro 255 and some 720cc secondaries. then to top it off a S-AFC. how much would i be making with all of that in place?
