does anyone know if there is any difference in the engines between a 1993/4 and a 2004 rx7? or is the rx8 engine the same aswell?

 

uh oh... (puts on fire resistant suit)

 

rx7 engine != rx8 engine

The difference between a 93-95 series engine and a 2002 can be found here...

Look for Series 6, 7 and 8 information.

 

2004 rx7's dont exist lol..
and the rx8 has a non-turbo engine with different ports..its not as powerful as the 13brew that the FD rx7 has.
ontop of that i hear that the rx8's renesis engine dosent even make as much power as advertised..

 

The renesis motor rx8 motor and the 13b-re motor rx7 are totally different engines the ports are in defferent locations. FYI not many builders like the renesis it was never though of as a good motor. The 2002 engine compared to the 93 engine is it has a little bit better turbos and the open up the intake side of the rotor housing both increasing horsepower by 30.

 

i thought it didnt but ive been told they still make them in austalia and new zealand, this breaker must have an rx 8 then, gutted, thought it may have been the same engine but without all the turbo bits etc which i could use off my exsisting blown engine

 

The rx8 isnt a bad engine. It has better emissions and I think it generates a decent amount of power for an N/A.
