Hey all, I'm looking at finally getting my RX8 after lusting for one since 2003

My question is this, if I go for a super clean 2004 will I be able to "easily" replace the motor with the 2009 version with the upgraded oil system?

I plan on installing a mild FI system so I figure there is a decent chance that after a few years of FI on the 2004 motor I just may need a new one

Sorry if there is a thread on this already but I couldn't seem to find one.

Thanks!!

 

thats kinda pointless....just get a rebuilt engine...Ive seen a few vendors on here sell them between 3 and 4k which is alot less then a brand new one.

And if your going FI then your gonna have a better cooling system anyways.

 

I think you miss the point. The 2009 motors have a 3rd oil nozle for better lubrication of the apex seal. If I have to pull the motor I'd rather raplace it with the most reliable/current version of the Renny.

What I'd like to know is if the footprint of the 2009 motor is the same and if there would be any ECU issues regarding the new motor...

As for engine replacment costs I'm looking down the road a few years atleast so it's hard to tell what that price difference would be by then.

 

If you are willing to drop a ton of money on FI and a new motor.. just save a little more and get the 09.

But I would not buy an 04 unless you replace the motor and such. There have been many failed engines and recalls on them. Try to get an 06+

 

I got an 04 with 30k miles so for and no problems at all.

 

If you're worried about lubrication just get a rebuilt pre 09 motor and run a good amount of premix and keep the OMP functional. Kinda of a waste to spend the money on an 09 motor, considering you would have to get a complete harness and ECU to make it work. It's not a plug and play with pre 09's.

 

 

Thanks, that's what I was looking for Looks like premix is the way to go

 

I second the just get the 09. However, I've noticed for the most part, that the people who are on the forums the most tend to have the least trouble. Either way do your research and you'll be fine.
