ill get to you in a sec i have a few wrongs to right
most gains are dependednt on the model of the 13b, the type of port job, and the supporting mods.
how wrong are you, theres plenty you can do to a rotary. if you mean theres nothing you can do internally your still wrong. intake and exhaust port street porting, bridge porting, j-porting, periphrial porting, ceramic seals, carbon seals, 3mm apex regrinds, hardened stationary gears, lightened rotors(more on this in a sec), etc.
why is it you wont find any parts? id hardly call a nitrous system "to the extreme". a monster bridge port, 3mm ceramic apex seals, T04R, 4" dump pipe, air inlet thru the headlight, 1200ccm injectors, and a 200shot of the fuzzy stuff would be an "extreme"
ohh god...
the first ture statment yet, turboing will allow the greatest gains for the least amount of money assuming you buy a TurboII
getting A lightened rotor is pointless (god i hope your not talking about brake rotors
) all moderrns rotary powered cars are 2 rotor motors so you'd need 2 lightened rotors but you wouldnt buy them just to get them, their more of a "while im in there type of thing" as ALL internal mods to a rotary require a full engine tear down. but most internal mods are un nessesary as rotarys poer producing potential are only limited by the amount of air the ports can flow up to a certain point(13b-rew's making 800-1000hp+ on a basicaly stock engine(all stock parts) exept for a nice big port job). on 13b-t's (FC turbo engines) the dowels start giving way at about 350-400hp tho, nothing you can really do about it, if your looking for high horsepower you'd better look into a 13b-rew swap.(Can be a pain in the ass, almost not worth it unless your building a race car)
explain to me son, what prevents nitrous from making power on rotaries? lmao
depends what you mean by "2 systems" as there are 2 stage systems. and what does nitrous have to do with messing up your timing? again lmao
