thinking of putting my cousin"s 94 rx7 engine on my 04 rx8 his engine has 88,898 miles stock the engine runs like new (think better then mine) mines has 69..but ill wait for the warranty i still have 2 years so is a working project

 

ok thanks for the news!

 

u welcome, btw nice pick of ur self U LOOK VERY HAPPY :D

 

You will have to piggyback computers to get the FD engine to work with all the electrical systems in the RX8.

 

what do u mean by piggyback??

 

I mean run 2 computers. One to run the FD engine and one to run the RX8 systems (including the electrical power steering). Then these will have to talk to each other.
Also, I don't think the motor mounts line up. New ones will half to be fabricated.

A FD swap is probably one of the easiest of the swaps. But in modern cars, nothing is drop-in easy.

 

There is a thread about this being done, but as noted you cannot drop in a 16 year old engine and turn the key and expect everything to work.

What you desire is a custom job.

that i didnt know thanx for the info man .. yeah its a custom job ill just have to wait and see ive done engine swaps on toyotas but on a rotary to be honest this is my first one so i dont have 2 much experience on them

 

What are you thinking? It's a lot of work, hassle, and modifying to do an engine swap within those two engines. And why put an rx7 engine rather than getting a refurbished rx8 engine? I know you have 2 more years to think about it until it will be a project for you. But anyways, let us know 2 years from now on what will you do about it. But for now, enjoy your rx8 engine and take care of it, rather than swapping it with an rx7 engine. Good luck on the route your going to.

 

Don't get me wrong, it will work nice once it's done. And it will be easier to make big HP numbers with the FD engine. It just won't be drop in easy.
