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

Already a post on this thing

 

someone on this forum already did this swap anyways.....but yes, there is already a thread on this...

 

CM, just out of curiosity.....Who already did the swap?

Kenn

 

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.

 

He abandoned the project. It has been done in Japan though.

 

id sure like to see it done. all the custom work would be a major PITA tho

 

very nice...so who will be the first here in the east coast????

 

too much $ for me, i rather do a 302. :Flameon:

 

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

have you seen the people that drive those things. they dont look like the oil checking type. its the honda civic mentality thing.

 

If you go visit alot of Mazda dealerships, you'll find that half the people that work there don't know squat about rotaries. They are just mechanics.

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.

 

I know about the one over here, but the shop that did it won't give out any info on how they got it past smog, I am assuming that they used the entire wireing harness and all acessories but not sure. (99% sure)
