Duals do I need anything so my car don't go pop!
OK I just cashed my financial aid check and I now have enough to buy the true duals I am talking with both mazdatrix and Suds7 about a system and will probably get it within the next two or three days. I need to know if I should get anything else before I instal them like S-AFC or somthing like that so that I do not run lean/rich whatever. I just don't want for my car to **** up after putting the duals on.

With the N/A you should have no problems. I'll admit I didn't have true duals on my N/A, but with RB header, silencer, y-pipe, and muffs (hehe muff). I never worried about running lean. Your fine!

Ummm, I'm not exactly sure of why you HOW you could "**** up" your engine by putting on an aftermarket exhaust...the only thing you are doing is freeing up a lot of exhaust gases...its going to help out a lot, I've heard good things about the true-dual set ups. Only downside I would assume would be that its going to be loud...but then again, I don't think there is a decent exhaust system out there that gives power and a quiet exhaust tone. Also, the popping you are talking about, its called afterburn, its gas burning/popping in the exhaust piping and it does that when you get rid of the cats, its not bad, hell, you'll shoot flames because of this...surely you aren't going to run cats? I don't think the true dual set up comes with a cat.

The stock n/a fuel system should be sufficent for up to 250hp if you stay n/a. People mostly use S-AFCs to lein out their air/fuel ratio to get more power thoughout the powerband. At least you asked though instead of just throwing some parts on their that you dont know the effects they would cause.

nono no no dude I meant POP like the big one you know the one that makes it neccesary to rebuild the engine. I know about afterburn and backfire and whatever else you call it. I just wanted to make sure my car would not run too lean and have the danger of blowing up.

You will be fine with the true duals....I have the Mazdatrix true dual and they are great! And not as loud as you would think.
As for more fuel, you will not need it at all! I have a huge street port on my n/a and I am running almost full rich!
So just buy the Mazdratrix true dual with the racing beat mufflers and you will love it
Good luck

TO get the same power to wheigt ratio I need (i think) to be at about 200rwhp and that is my goal. I know it is very ambitous but I do not have to worry because I still have some time(2-3years) until I will realy have to prove my car's worth and defend Mazda Rotaries.

I've had the true duals. No problems with the stock ecu. If you want 200 rwhp you'll need a standalone ecu and a streetport. If you have a streetport then you don't want true duals. They ONLY work good on stock port rotaries. I always have to repeat this every time someone posts on the subject. You absolutely need to have a collected exhaust on a ported engine. I now have a ported motor in my GSL-SE. I played around and tried the duals. Power wasn't all that impressive but it was better than the stock exhaust. It worked better with a collected system. On my old stock port 2nd gen it was entirely the opposite. I had fantastic power all the way through the power band but I suspect the ultimate top end suffered as compared to the collected. Average power is what wins races though not peak power. The duals also sounds like crap. Try to get your engine to run on one rotor. Thats what they sound like.

I am in the research stage of getting the haltech E6k and would like some help with what I will need. I don;t exactly know what I do need so if anyone could help me out with a list. I only plan to port if the old Bee blows but I don't expect it to(soon anyways). I am also going to change to an LSD and a MANUAL steering rack and lighten the car as much as possible(without spending a lot of $$$$$) I might also replace my sunroof with LEXAN but I dont know yet. What I realy need right now is help with the E6K. Thanks to all for the tips and advice.

I hope I have about 205 rwhp on my car right now, and yes its a big goal and hard to do. But you do not need the ek6 just get a S-AFC and you will be set. Hopefully the dyno soon will show I have about 205 Cant wait!

Flyby: I hope your dual system works better on your ported motor than mine did. Then again at the time I couldn't tune it in any way. I do know that MY motor makes more power collected. I do want to see the results from your port job though. That thing looks really cool. Can't wait for the dyno chart. If you top 200 rwhp then just think how much better it could be with a standalone ecu and no factory afm to restrict airflow!!!
On bridgeported and peripheral ported engines you will lose hp over a single system due to the increased overlap and the lack of exhaust scavenging. My streetport is as big as I could get it with as much overlap as I could get without a bridge. This is why mine didn't work so well dualled out. If your ports are larger but overlap isn't increased then it would work great. Good luck with which ever route you choose.
