im thinking about buying a 84 mazda rx7. all i know is it has a rotary engine. does anyone know if they are fast, or if there is anthing i can put on it to make it faster? (manual trans)
an aftermarket air filter like HKS superflow, K&N won't hurt anything except even worse gas mileage. Top that with free flowing exhaust, yes, you get more power, but you WILL see your mileage numbers drop really quick...Originally posted by hotown it runs good now. is the factory motor pretty quick? could i put a cold air intake and exhaust to make faster?
I wouldn't. Rotary engines are like 1/10th the prices of 4stroke engines in Asia. People simply swap to another rotary should one fail. The workmanship is so much more expensive than the engine itself.Originally posted by MopeDman rotary's are very tempramental in weather too......if its humid out they may not start...
and engine parts are kinda expensive.....and not many mechanics know about rotaries...
IF i bought it.........i would search around for an old chevy truck or sumthin with a 350 in it......then swap it in..... make it hella fast and cheap for parts.....
really? Hmmm....Originally posted by nick3470 actually in japan they have to swap out the engines about every 50000 miles to keep them under emissions laws
