RENESIS engine in an FD??????
I was just wondering if anyone had considered a RENESIS swap in an FD? And if anyone had what did you find out? I wonder because it seems to me that @ 250 hp Normally Aspirated there is a lot more potential for horses.Also word has it they would are more reliable and less troublesome for daily-driving. If anyone did check this out what type of cost would be associated with this endeviour?
Thanks,
Catlin M.

You know, everything is just theory now. We have no clue how the renesis will react to a turbo. For all we know, it could be running 11:1 compression, and adding a turbo with just 10psi will make it pop.

I love how everyone just ASSUMES the Renesis is going to be a reliable engine when no one has even driven one yet. Maybe they will be, maybe they won't be. It's going to take them being in service for some time before we know for sure. Autodom is full of examples of things which looked good in development and even reliability testing, only to be found to be a major design flaw once cars got in customer's hands.
Plastic AST anyone?

I have been told that because of the configuration of the the new Renesis engine that it will be just about impossible to add a turbo. I doubt a supercharger will be able to add more than 6 or 7 lbs. Maybe you could add one of those new computer controlled NOS systems. I know I could never take just having 250 horses, so it may be a while before we learn what that engine can really do. I am not happy with the 300 horses I am getting now. My bet is that it would be reliable in stock form. I got about 150,000 miles on my stock first gen before it started to smoke and needed a rebuild.

If it even becomes available through "standard" aftermarket channels, what makes anyone think that this is going to be at all cost effective? It is not going to be a direct replacement...there will be major mods.
If I really wanted more torque, I would go for a 20B. Yeah, there are major mods there too, but it likely has more potential anyway.

I dont think adding a turbo will be an issue, but it WILL require some CREATIVE plumbing. Any one wants to really add a turbo, they will add one.

They brought the compression of the Rene up to around 10:1. Isn't the compression in the 13B-REW like 8.5:1? With fuel mods and ECU and whatnot, what's the most pressure you can run DAILY? 14, maybe 15 PSI? So what's to say that you can't give the Renesis 8-10 psi? With obvious mods to ensure you don't pop it, I'm sure it's possible.

i heard that a 4th gen rx7 was being discussed in mazda.. and it would have the renesis engine with the twin turbo induction on it..?? i heard this awhile ago in some thread.. if so that would be the car to wait for.. imo i think the fd is a way better looking car the the rx8

I would never do it. Torque being 1 reason and potential in the modding catagory as the other reason. No way you can produce as much power through N/A rotarys as with a F/I rotarys. Power is higher on my scale than reliability.

The Renesis was designed to handle a turbo as quoted by a Mazda engineer on Rotary News. Also, check out the www.rx8forum.com...

Have any of u see this engine close up? I went 2 times to the NY auto show just to get more info from the eninge they had on display. This engine is complete different engine except for exterior design, This engine use 6 injectors, oil injectors is competely different instead of 1 outlet it has 2 to spray into the charmbers, Also it has throttle sensor like some piston engine does behind the air intake. I had ask one of the mazda rep to removed the cover from the engine bay. when did it I took some pictures of it the alternator is mounted on right side. And this is the only reason why I envy on the Renesis engine is that it does not have all the nightmare solenoids that we have on the 3rd gen. In my opinion it will be the other way around u will finds guys asking to put in 3 gen motor in the Rx8. Also the Rx8 has more engine room so can put the 3gen engine with a single turbo and make it a killer Rx8.

like every one said... Its just assuming.. But lets just think Positive Thoughts. not Negitive ones.

I don't even know where to begin with the rotary to do something like that. I would think you'd have to change the dimentions of the rotor itself to accomplish that, which means that it's not even worth it IMO. I suppose if the housings were the same dimentions, and the seals on both new and old generation rotors were the same going on the assumption that the rotors were different in size, then theoretically you might be able to. And that might be a good idea with the "improved effeciency" of the side ports and all. Damn...did I just get way too into that?
