now now now dont slam me here... i know most of you guys say Heck no for nitrous on these motors... but im rebuilding my motor now anyways... and my neighbor has a 1st gen rx-7 and its not turbo'd and hes running nitrous just a 100 shot.. he was like you should build it and run some good boost and thow a 25-50 shot on it for the strip and it be crazy lol.... that got me thinking not that I will be using nitrous but really why is nitrous looked soo down on for the twin turbo rotary motors??? what makes them fail exe... and if i were to want to run nitrous what precautions should one take?? just honest questions and please dont slam me for this... I did seach and didnt find anything but no nitrous and vin diesel and stuff lol im looking for real answers as to why.. mainly for my knowledge..\
Thanks Guys

well i was just curious that everyone is sating it will kill your engine and stuff and not to do it. but i know up to a 50 shot isnt much at all.. I was just asking why everyone hates it soo much on rotary motors expecially on the fd's. does the instant cooling have an affect on the seals that cause them to crack or something.. I persoanlly dont see a 50 shot being a problem on a 13b rew, and i have considered it after a rebuild but id like to go with it unless someone can give me a good reason why its worse on a rotary motor rather than a piston motor? im not baggin on anyone im just looking for facts..

Nitrous properly tuned by a PROFESSIONAL WITH EXPERIENCE with NITROUS and ROTARIES
wich honestly there aren't that many of
is GREAT!!!
trying to just "bolt on" some "kit" without consulting a professional you WILL BLOW YOUR ENGINE do not get any type of KIT until consulting someone with the appropriate experience.
Now, theres not that many "rotary specialists" around out of those that are only a certain very small percentage are experienced to do nitrous on rotary engine so basically your looking for certain people normally drag racers of course.
my advice : contact Judge Ito if you dont know how you can just PM him on this forum. he can answer ALL you questions and then some.!

excellent thanks villan!!
well my brother used to work for holley in there nitrous department for r&d he now works for deere with me in our r&d department. hes very knowledgeable on nitrous and how it works exe.. when i talked to him he says hes positive it can be done and everything and was explaining it to me but when i said i had a rotary motor he was like ohh... lol he doesnt know much about them but he said on the average engine nitrous can and will be safe if you correctly use it. he did tell me not to go hogwild on it unless my motor is built.. he did say on a stock motor you can normally run up to half the rated horse the motor is putting out (there are some exceptions) i told him what about a 50 shot he said that is very minimal but still can destroy a engine very easily... basically he told me when i get it dyno tuned run a wet kit and make sure its rich to start with go with the correct jets get my car tuned for the turbo first then tune with nitrous.
anyways he told me tune rich and work down till it shows correctly on a wideband. that is very laymans he said but its the correct way to do it. he also said to buy into a purge kit and gauges they are worth a bundle on a nitrous motor.. so after talkin to him on it i feel pretty confident on running a 50 shot after my rebuild. but i will not jump right into it. I will PM the man and get a 2nd opnion and see what he has to say..
thanks guys... now i gotta rebuild my motor, ohh by the way i purchased a rotaryavation rebuild kit earlier i did a search and i see people have good luck with them so lets hope!! and lets hope i get my fd back on the road come springtime!!!

Well, sounds like you already now someone w/ ton of N2 experience..
My take on nitrous.. Its already hard to tune your car with turbo(s) and its going to be even harder with Nitrous. Its not just about adding it, you would need to change the map on your ECU to handle it. Like Villain has mentioned, it needs to be done by professionals who have experience running N2 on rotaries. Also, Good turbo(s) should be able to compensate whatever N2 set up your thinking of. Its just not easy as bolting up a kit... you might spend up to a grand getting it tuned....

so pretty much ditch the nitrous idea and just spend the money on going with a nice single 60-1 turbo or gt35 or something simular rather than the stock twins? it be safer and easier to tune in the long run. and not e all that much more money.

I would... if I had to choose between N2 or nice single... But like I said, depend on what you want.. If you want a drag car, maybe N2, large single car, that you know when you are going to spray on a leveled drag strip.
If you want a good all around single car to drive and make few quick runs, good tuned single would be my choice..

Herb, i already bought a large m2 SMIC, and im scared if i go with a single the SMIC wont be that good. has anyone ran singles with the side mounts with success?? if i go single I will most likely keep the smic system and just run some sort of duct work to direct air into it or something... just tryin to get ducks in a row here.
