I recently bought a rx7 and i have a engine out in my rx8 and i also just bought a 13b injection engine from a auctioned rx7 frfom a salvage yard and i was curious if the 87 rx7 engine could be installed into the 04 rx8.

 

An N/A FC engine in an RX-8? Well anything is possible......

 

why would you want to put a 146hp NA FC engine in place of a 232hp NA Renesis engine?

 

im just trying to get my rx8 back on the road for less than $11,775 that mazda quoted me and i got the deal of a life time on the salvage rx7 parts praticaly a steal for engine and trany for $450 plus every thing under the hood and the dash for $250 more

 

i want my rx8 on the road again and i want to make it manual drive also

 

the engine and trany are in great shape runs great and had less problems than the renesis engine.

 

anything is possible, it won't be easy though.

 

You can get a used renensis from Atkins Rotary or MazMart for waaaay less then that.

 

To be more charitable, they are rebuilds. Usually what, a little less than 2 grand? And all the sensors will plug right-in. Your gauges would work.
