I know a lot of the jdm engines are more stout than the usdm egines, I was wondering if the same thing applys to the jdm rotarys. Do they put the same 13bt in the turbo II's in us?

I also wanted to know if a nos appilcation on a rotary will reduce the engines life, significant or not, Thanks.

Yes they do, only thing prolly different is the emission equipment, even that there they same.

IMHO i think Nitrous is bad.

more boost is better

is there anyone on the boart that's using nitrous?

Why?

I know of a couple of NA guys that do, but I can't think of any TII guys.

It's rare because of the difficulty in tuning. Some local turbo/IC shop had some CRAZY 500+whp FD running nitrous and the first time they hit nitrous, they just blew the motor. LOL

Just don't do nitrous unless you know exactly what you're doing.

Apart from a few emission-related external differnces, it's exactly the same engine.

It's all the same parts.

NOS significantly increases power.
Increased power increases loads on all the engine parts.
Increased power also increases heat.
You think it'll reduce engine life?

NOS helps cool down the extremly high temps created by the turbo.

RETed

Wrong.
It's the intercooler's job to be doing that.

Yup.. the day that nos cools down stuff...

GT34

Of course it will reduce the engines life. But will the TII be able to take it with it's cooling system? Is it sufficient enough? With all engine cooling aspects out of the way, will the rotary be able to take the extra load on the engine caused by the nos in the system. Keep in mind the rotary might not start the next time you head out, or it could make it to 150k. But what's the logic behind using nos? Does it deteriorate the apex seals?

No man... A stock Turbo II would definitely not be cut out to deal with NO2. Of course, you could make anything work with the right supporting mods, but seriously, NO2 is a "rare" path to power for a streetable turbo rotary.

The rotary can handle just about anything except detonation and over-heating. And no, NO2 (in and of itself) does not deteriorate the apex-seals. But yeah, just don't do it.

BTW, do you have an Rx7?

Well, that is all sound advice, but if he sprayed like a 50 shot with proper tuning he should be ok for a long time. I personally (in my youth lol) sprayed a 75 shot on a car I was told could barely hold a 50 shot. I didn't mind if I blew the engine but I was still curious. I went through about 4 tanks before I took it off. Never blew the motor.

There is also a quote about rotaries that I remember to this day. "Driving a rotary is unbelievable, driving a boosted rotary is phenomenal, driving a boosted rotary on N02 is just stupid retarded!" (stupid retarded meaning the absolute plateau of unbelievable performance.... his vocabulary wasn't to strong lol!)

If you spray, please let us know, I'm pretty sure there are quite a few people interested to see how it does.

If Vin Diesel can do it so can you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!111``1`one`11!

No, you don't understand.
It's the instantaneous spike in power that leads to increased wear&tear.
Even with high power 13B's, you don't just go *BAM* instant increase in power.
The power is gradually increased as RPM's rise.

Even with the 50 shot mentioned above, on an NA, that's like a 30% increase in power at the push of a button.

No not yet. I'm looking trade in my trubo mx6 for a TII rx7. I'm trying to learn as much about the rotary before I buy one. The reason I'm asking about the nos on the rx7 is because I'm looking into buying a jdm one with nitrous. I'm a little iffy because it's already got 144km on it and I've seen quite a few 7's with rebuilt engines in them before that milage. But from what learned it's better not to have little or no carbon build up. And the best way to keep it down is by stomping on the gas every once and a while. That's why I'm thinking nos would help keep that down.
