@cloud100, stop spreading false info, air intakeS? turbo? b16? the stock engine comes with 240cc injectors already, why do you want 280cc injectors? if you dont know what you're talking about, its best to stay out of it, sorry for being a d*ck, but i had to.
@MDbasim, your engines a d16w9, there arent any superchargers for this model, and no, you cant swap in a b16. Yes you can run 7 psi turbo and a 50 shot safely on everything stock, given that your cars tuned well, your best bet is management, which is either kpro or aem ems. If you think im speaking in french, its best that you either search on international forums, or just by an rx8. i suggest you piece up a nice turbo kit, go for a t3 super 60 turbine, custom made turbo manifold, taiwanese intercooler, locally made intercooler piping with 3" piping, hondata kpro ecu management, 525 cc deastch work injectors, bov, and a 50 shot nitrous.
this will cost a good 450-500 thousand rupees
go to my threads and check my turbo civic out, its a 2005 model...shoot me an email if you need any help.
