Hey trex...can you please explain to me in detail all about how a rotary works and what the reason for apex seal failure is, oh also Why does adding a midpipe even create higher boost pressure? If you can answer all of my questions in full then you do have room to speak, but if you cant...according to your logic then you shouldn't even own a rotary...Not trying to start a flame war. just giving a diff way to look at it.

 

whats a rotary?

 

For info on porting the wastegate, see my site, and go to: Upgrades --> Engine --> Turbos --> Wastegate Porting.

 

lol stop it already!

alright here's the deal. I don't want to comment much on the above but I have to....
Dude when I saw this thread just now I almost choked on my gatorade. Many of these people didn't know much about their cars when they got them (me included) but they made the effort to learn on their own. The forum is very useful as a self teaching tool. You can search for any term or question and get much information specific to that. Perhaps you are searching in an inefficient way and not specific enough. You have to try to think of a couple words that would be in a post about your question try that method. Like you said, they shouldn't make fun of you for asking that question since you want to learn and they probably didn't know about this when they first got their cars either. This is true but it is almost embarrasing to ask a question like this ever so they probably searched for what a wastegate is and pretended like they always knew it since it is basic terminology. It seems that you just were frustrated by all the threads that came up and became lazy and didn't want to look through all of those. I don't blame you but have a little pride and know what you are talking about and then ask a specific question. That is the only thing the forum is for is specific questions that have not been answered because everything else is already backed up somewhere on the forum and can be brought back from the dead by searching.

I'd like to add that there are 2 types of boost you have to worry about boost creep and boost spike. I believe that you lessen the creep by making the wastegate bigger or buying a bigger one and boost spike can be controlled by a boost controller manual or electronic if you can afford that.

The midpipe is one of the hugest steps in upgrades and it seems like you are very unclear about modding the car. I have thought about the midpipe and done research for a while now and I still have questions about it. I am telling you to not do it until you are sure of what is going on. What upgraded ecu do you have? Do you have an upgraded radiator, ast, boost gauge, water temp gauge, fan mod, downpipe? Those are the basic rel. mods. Next, since you have an afermarket ecu I don't know if it needs to be tuned for your mods or if it is preprogrammed but I would get a intake and catback. Also before you start doing these things what is the condition of your motor and turbos? Get a compression check and test the pressure of the coolant system and with the boost gauge your boost pattern. If you have a problem it is stupid to add mods without fixing that first. If you want to run higher than 10 psi you should get an intercooler and a fuel pump. Then you can run 13 psi and that imo would be maxing out the stock twins if you want them to have close to a normal life span. If you get your wastegate ported and a manual or electronic boost controller you can then put in the midpipe safely and it will make it easier for the turbos to boost to 13 psi. You will lose lower end power with the midpipe but the gains up top will make up for the loss below and get you better 1/4 mile times.

good luck & do it right

 

He wasnt sure of the answer so whats wrong with asking the "knowledgeable" people of this forum.

 

Thanks, Steve. You've been providing me and a lot of others a free RX-7 resource for years. Without criticism.

 

You are welcome.

I remember how "dumb" I was when I bought my '7, as I had only owned normally aspirated V8s before that. It takes a while to come up to speed on rotaries, and if you throw a turbo on top of that, there is a massive amount to learn.

 

You guys that are so quick to "flame" whenever you see a post that offends you would do this Forum a big favor by simply not responding at all.

There will always be newcomers to the rotary world and with the newcomers there will be newbie questions. We should be welcoming these new folks who will be keeping the rotary going. With a little experience they may become the next experts that help us all.

What ever happened to tolerance?

 

Is a wankel the same thing as a widget?

~11K on motor #2. 93k on chassis. I'm the Xth owner. I knew a bit about these before I got mine (6 weeks ago) and have been brainstorming ever since. Needless to say this whole site has been a wealth of knowledge, but I have to say that not EVERYTHING I need is on here. Beeing a newbie myself, I don't have room to criticize either way, but I would have to say that 1) there are some pretty basic questions asked here that don't have to be, and 2) some posts are...well, those who post them need some anger management... Funny though...

 

Why would it make any difference if the question is basic or complex. If you want to answer do so, if not move on to another post for gosh sakes.

 

Ive been running 15 lbs of boost. My mods are a Downpipe. what should my next mod be?

 

jokes aside...steve cirian..your site is WONDERFUL!

I wanted to thank you on behalf of all of us who page through all the great info you have put together. I was on there yesterday trying to figure out some profec b and boost related issues.

excellent resource...really excellent. It's been my bible for the past three years. between this forum and your site it has been possible for me to actually explore this car with the wisdom of others experiences.

thanks again

rotary. !!!!!! WTF. i thought i had a four cylinder supercharged Rx-7. no wonder. god dam it. i want my honda back.

give the guy a break. i am a newbie and did a lot of research. read for hours and still it's hard to figure everything out. sometimes you just need a little clarification. besides i thoght the forum was for help from knowledgeable rx7 gods to lowlife newbies. j/k hahahahahahhahahh.

 

Why is it that when driving the car (stock) I will get it to boost and let off on the gas a little, get it to start blowing off and then push on the gas it will then continue to blow off as I am accelerating?

 

I dont think that is normal when you are accelerating you shouldn't hear the bov at all
maybe you are hearing the turbo spooling up?

 

Wow boys, can we pull our heads out of our asses and help our fellow FD owner? Damn, i thought there was a comradity between FD owners. So please, be kind to the noobies!

 

you cant compare this to a mechanic.. its a totally different issue. this guy is just asking a question, a mechanic is being paid to do work for you.. bigggggg difference.. anyways

yes, people here are harsh, but you really should check out the entire search. just cause you dont see what you want in the first couple of threads of the search doesnt mean you should just screw it.. chances are you'll learn something else while your looking through.

 

he did search.....and when searching for things like this sometimes there are thousands of items that come up. so make a new thread, ask the question....and if you know the answer, help him out or point him in the right direction. i search for stuff all the time, but sometimes, especially when you're a newbie (like me) you see things totally different, and need something cleared up.

 

Sorry to resurrect one - but this is gold best explanation i have seen yet.

 

Good lord - you sure were diggin' eh?

 

Some people just do not know learn on their own.
Must have been caused by bad parents or bad schooling.

We are here to help learn about the FD. Not how to take a first step.
Life is hard and if you do not learn/adapt, you suffer.

 

thats right biiieeetches....you better listen to mr. chucky!!

In the future, instead of just doing a broad/non-specific search to find a possible answer check the FAQ as well. That's what it' there for.

Knowledge is key with these car's, I don't claim to know everything (or even a whole lot) about these car's, but I did do about 3 months of straight research on the FD before I bought one. Read the WHOLE FAQ and comb through the Archives, most all questions about these car's have already been asked and answered somewhere in here. If you have a question that hasn't been answered and you ask it in an intelligent manner chances are you won't get flamed.

Why is everybody referring to the OP a newb? His handle says he's been on since 2001...

 

Well for starters, this thread is from 02.

Now with that said, the FAQ back then wasn't nearly what it is today. check the time stamps on the posts in the FAQ...

 

LOL, good point =P Basically owned myself (with the assist)

So whats with the crazy resurrection?
