"fast as ****": well i might've exaggerated a lil, i dont want it too fast, just because idk a racetrack i could unleash all that power on so it would seem kind of pointless for the street, but say around 400-450 hp

"durable": i'd like it to last to atleast 150k - 175k miles, which i hear is very possible as long as you treat the rotary correctly

"LS7 crate motor": Isn't that american muscle? a little contradictory to me it seems to be put in a Jap car, but on the bright side, I am a fan of chevy

 

not true

there is at least one way to create overlap and still keep it MSP and this is why its important to go to 7stock Bagged-one. you can sit in a room with Rick Engman , Carlos Lopez , various members of Speed Source etc


cheap , fast, durable. pick two.

 

No such claims have been reported... yet


Are you serious???

 

I admit I'm about a 3 month 8 owner, but IF you researched the car more, and just knew this in general, but this engine is quite small (1.3L).. IF it were possible to crank over 400 horses into it, its just not good for that little engine.. It wouldn't last long. I was in the same mental boat as you, but mine sank not too long ago. If you want 400 horses, you need to buy a car with 400 hp stock. This isn't Gran Turismo where you can just buy a 10,000 credit exhaust and get over 50 hp from it. Mazda designed this car so amazingly, that even stock is almost race ready, at least a good contender. Its hard to find another car at the same price with the same amazing handling and suspension, and comfort... And 4 door 4 seater with reasonable trunk space It is what it is. Even the stock exhaust system is awesome! And I have heard this engine will usually put out till 100k, thats usually when its done for, so I heard.. Pushing more power through it decreases engine life.. So unless you have tons of money and lots of free time... Have fun exploring endless possibilities

Thats my 2 cents

 

idk, i read somewhere that rotarys could be just as reliable as piston engines if driven a lot and redlining a lot and maintaining it properly etc... but ive been looking around on this forum and it seems that some guy named LambertRX8 had 168,000 as of dec 08. He hasnt been on in awhile, but he had the original motor. Besides that though, reading peoples threads, it seems most get problems around 75-100k

 

400-450HP? You really need a driver mod as well to drive a car with that amount of power. Have you ever driven one?


Stock renesis engines rarely go past the 150k miles mark. 400hp means a lot of dedication and maintenance. You're doubling the engine's output in the end.

 

soo, what was this guy talking about? Has anyone ever put an LS7 crate motor in an rx8? How did that go durbaility-wise? Im assuming it has a lot of power

 

I disregarded most of what you said as it was irrelevant and this statement is simply FALSE... Quite frankly, reliability issues would be a YOU problem depending on the circumstances...


(been discussed/old news). Again you are not going to make the RX-8 by your definition "fast as ****" without some form of FI, swap, nitrous, or whatever you want. The Renesis or any motor for that matter will not be a reliable daily driver if you go the "fast as ****" route; therefore requiring rebuilds sooner than "normal" if it were to become a daily driver.




pointless....

 

Whats the difference? Plenty of RX7s with LS# swaps. It is the standard for drop and forget power. There are even a few RX8s with LS1-3 running around. LS7 has the same mounts (it wont be the same to squeeze it in there tho)

That wasn't worth 2 cents. So much ridiculousness in this thread. What is RX8club coming to?

As for 400hp daily driven, reliable renesis... it is only a matter of time. Seriously.

 

bhop, I was trying to point out the fact that a stock rx8 is already better than other cars on the road, and it seems like he wants to "improve" a car that he doesn't own, and possibly never driven one either? Lol. Just throwing out a different view of the 8, because most mods are pointless if you don't even take it on the track.. Example: offroad truck never taken off road, classic

 

My internal sense of fun disagrees with this sentiment every time I put my foot down in my "pointlessly" turbocharged 8.

 

to each his own, I like my 8 just the way it is

 

Why not just buy a chevy instead of dropping a LS-watever into an RX-8? Are there certain advantages to doing that?

 

because rotors eat pistons for breakfast

 

Look, you are twisting this all up in knots. Nevertheless, have you ever driven a Chevy? An RX7/8? I rest my case.

 

Sell the 8. Buy a chevy
My .02

 

He doesn't even own one.... like I said, this thread is pointless.

 

it would be pointless getting an rx-8 and then asking all these questions. Talk about about a buzzkill . I have driven a chevy before. Also a GMC and currently a Cadillac, but never an RX-8. I had started this topic with the assumption that rotary engines are long-lasting. If i had known theyre not so much, I wouldnt have started this because I am in search for a reliable car to last me to about atleast 150k miles. THANKS TO EVERYONE though who has put up with me through this thread . I appreciate the help

 

I heard Ford made a mistake with their F-150 engines... They never fail

 

except that overlap alone isn't going to adress the flow limitations of the Renesis ports so it's a moot point really. Ultimately the only way to get any more substantial NA power out of a Renesis is to p-port both the intake and the exhaust, and why bother using the Renesis as the basis for that style of rotary engine?

and I also don't have to attend SS to get world class advice on the Renesis, you're kidding yourself if you think the really hot information is revealed publicly there ....

 

if carlos says it does and rick agrees who am i to disagree? of course it depends on your needs and your definition of substantial.

 

My take on the above topic is this....

Other than for purpose built motors that may be limited by motorsports classification, it seems an utter waste of time and money for an individual to go down that road anyway. For the investment returns (in terms of money, trouble, time, etc), FI wins hands down.


but hey, we might as well discuss is, since the OP is clearly:

 

yea,

wtf do you know! and wow.

beers

 

If you haven't seen the actual numbers then you are neither in a position to agree nor disagree

Otherwise you have me at a disadvantage ....

 

My msp has been ported. It is very loud, as most people who have heard it know. It doesn't do the "brap, brap, brap" like my 13b-rew did but I like that. It is pretty expensive (I through in some ceramics while I was in there and got the plates re-nitrided) and lots of rushed hours. I do not plan on going FI with my 8 so I figured what the hell. Got a little more power, my car screams at 9.5k but it is not recommended for the uneducated/no-experience rotary owner.
I did notice the difference in the cooling ducts/water jackets what ever you call them, THAT is the biggest difference aside from the side ports that I noticed. You can't just port the hell out of it like the older 12a/13b's.
My 2 cents for the archive.
