So who is installing the rotors? Are you having anything else done to the motor while you are in there? I am sure that the racing beat rotors are a quality part, I am just not sure it is the best money spent but if you already have them then go for it.

Turbos don't blow up motors, tuning does. S0rry.

Okay wise ***, there is no reason a 11 to 1 air fuel ratio should have problems with my engine, at 8:1 compression, and absolutely no reason 25 psi should do damage to the motor but it did.

I don't know why, I had checked fuel pressure at first but it wasn't an issue, there are no stuck valves, no defective parts but the Turbo.

Maybe I just got shanked with my supplier, but I don't care anymore, the Diesel's use em fine, I'm Turbonetics and Greddy, Mitsubishi isn't bad either.

And yes the Turbo blew it up, it's not the internals I lost the engine with, it's the cylinder head, hood, valve cover, alot of the passenger side engine and front was destroyed, un-recoverable as it chipped the block in several key locations and tore the vaccuum lines and a fair portion of the intake mani up too.

You do realize that Turbonetics uses Garrett turbos, right?

ravenforbidden

That's not my point, Turbonetics and Greddy themselves are not the issue, the supplyer from Garrett itself is the issue.

Wow we are way off topic now...

Does anybody know if the 88 Greddy Turbo will bolt up to the RX-8 or will I have to fab out a new manifold? I would like to think so, but I'm more a Centrifugal Supercharger expert than a turbo one.

Say what you want, I don't have the pics and I hate garrett, that's just my choice, doesn't mean you need to sway my post away from target.

You wanna talk about the Fox well we can talk all you want in private message, I will end that the Hellion Kit has bit the dust recently as well, though that was more my amusement than anything, and I'm installing the new Procharger F-1R kit next December (09) when I finish my two runner projects.

Now back to topic.

Fluid pointed out that the Greddy kit is complete, with a 'Greddy' turbo, two pieces of exhaust manifold, and all the cold side plumbing and control bits......

Okay but will that bolt to the larger 88 mm? I would imagine if I cranked the Octane up, ported, and possibly added some other helpers I could see a larger turbo used, maybe not an 88, but larger than provided.

If you need more power than a GT3071R can produce than the rx8 was the wrong choice for you.

No.

There is very little room down there for anything.
The medium frame Garrett barely makes it and the 3071 is the highest output turbo available in that size from anyone.
And it doesn't "bolt up" - it requires modification.
Hence the need for the BHR/MM kit.

that statement is not complete enough to be considered true or false. if you were way out of the efficiency range of the turbo @ 25psi, and creating ridiculous charge temps, then that AFR at that compression still = boom.

i'm not saying that was the case, just saying you seem to be overlooking a lot of things in your opinions, including physics.

i find it funny that raven thinks the same rules apply with turbo'd mustangs and a turbo'd Renesis.

you sir are a boob.
kthxbye.

ravenforbidden

Turbo's are fundemental products, and despite being a Rotary the Renesis still operates as an engine and has many characteristics like a V-8.

With a Air to Air intercooler blasted by chilled CO2 I doubt it was charge temp, like I said the turbo blew up not the motor.

TO BE CLEAR IT FRAGED AND TOOK THE UNDERHOOD WITH IT

I do not know how that could happen with Royal Purple synthetic that was running a temp no higher than 150 when it blew, I have gauges and a ECU system that recalls all that for me and nothing was even remotely close to redline, the TURBO was defective, twice, I didn't even make two runs with either Turbo, and the 76mm Y2k BB has held strong despite being a mismatched Turbo, even though I fragged that out recently I blame myself for racing it on pump gas.

This time it was intentional enough I saved my motor, and will just be going to a Centrifugal Blower that runs a hell of alot colder...

It's already been said, Turbonetics turbos are just modified Garrett framed turbos. They used the same cRaPPy parts.

ravenforbidden

But it is my firm belief the single ceramic ball bearing turbo (Turbonetics) is superiour to the dual ball bearing turbo used by Garrett.

Look I know you have great experiences with the Turbo, but I have not okay, talk about it all you want, I'm probably just one unlucky sob with those Turbo's, but I'm telling you it happened and I'm not happy with the product anymore.

Talk about it all you want, the Turbo blew up twice, not the motor, not defective parts causing the Turbo to fail like the intercooler and things where fine, it was the Turbo unit itself which detonated twice.

Maybe rather than using the same exact setup Turbonetics has something that works better with what I do, non of the Garrett user's I race now can keep up with me at 8.08 secs in full trim, audio, and occaisionally joyrider loaded up.
