Anyone wanting to do a Renesis swap??

Doesn't look like too bad of a deal...will need an ECU and exhaust to begin with, but that's pretty expected.

that's my bad....He started the project, but I don't know if he finished it....He was dropping it into a GSL-SE.....Search for Renesis swap in the 1st gen specific section.

Why would you want to do a Renesis swap? My friend who works at the Mazda dealership shop says that the engines flood out too easily and they have to replace the engines almost on a weekly basis. It isn't as powerful as the the REW engine and has very little torque at all. The TII engine or the FD engine would be better swaps.

Umm... ALL rotaries flood out too easily... and why are they replacing so many? Any reasoning behind this? They have better apex design, and as long as you're keeping your oil level up, you should be okay for lubrication like the other models.. not much danger of detonation.. though they DO have 10:1 compression N/A

The RX-8 flooding issue has since been remedied with newer ecu flashes. It can still happen every once in a while though but this is true of any rotary.
No joke it isn't as powerful as the 13B REW. It doesn't have turbos. Turbos give the REW more low end power and therefore torque. How much power does the Renesis make compared to the last nonturbo rotary? It most certainly does make good power and torque for a nonturbo rotary. Don't compare it to ported or race rotaries either. Keep it on the same level. Compare apples to apples. Comparing a nonturbo Renesis to a turbo REW is almost as silly as comparing a 12A to an LS1. Not the same thing.
The RX-8's do not have major engine replacement issues. They have had a few though and these were early on. It seems during engine assembly in Hiroshima, a few water seals got pinched and caused the engine to leak. Doesn't sound like a reliability issue to me but rather an assembly mistake. All Mazda rotaries are built in this one plant btw. Condering the number of cars sold so far and the relatively few number of engines replaced, they haven't really had an issues. How many things did the 3rd gens have wrong? How long do their engines last? Why is the Renesis bad again?

I want to do a RENESIS for my next engine, but that will be a few years, as I just got a fresh engine installed...

Okay, my response came from RX-8 driving expirence and the knowledge of mechanics, and not your usual dealership mechanics. Mazda gives you specific instructions that are annoying and time consuming. Even with a turbo it only has 240rwhp, though more than a REW, is not a big gain for forced induction. Even with the turbo it still has less torque than an REW. It is not a tunable engine, cutting the exhaust completely only gets 8HP gains. If you like it that is you but from my expirence it is not a good engine and not as reliable as everybody says it is.
