Wats up
Ok Rotors or "Rotary's " in Mazda Rx7 are a good engine if u no wat u r doing?
and depends on which Series u are look for
Rx7 s1-3 comes with 12A Rotary ( 1.2 L )
Rx7 s4-5 is the 13B Rotary ( 1.3L )
And the s6-8 is the same 13B ( 1.3L )
well i hope u no the Base of a Rotary
its true that u need to service the engine but its not 10,000kms
it's every 100,000kms is when u need to do a full rebuild,
The price of the service depend on how well u take good care of the engine as well?
And modifying a Rotary can be a little tricky if u want to keep it legal on street
most people i know try to port there engine
its free up the exhaust so better air flow and sometime misfire that makes a
BANG BANG sound in some which sound's bad
but if u r a Rotary head like some people then its just natural
but by doing this u may get a lot of hit's from the police because its illegal
there other ways like simple mods but this is the most common in where i hang out
But if u modify the engine wrong then well u can't salvage a lot from it
I hope its helps and good luck with it
