look, I don't know about you guys claiming that the N/A's were built for handling and the TII's built for speed, I think that's a bunch of hogswash... its all a market thing, tII's were more expensive and there was a great mistrust of Turbo's back in the late 80's, hence, the N/A's (GTU's for sporty/cheap people, GXL's for those who wanted a nicer ride) I've driven both types, HARD, and actually, in stock form, the TII's handled better both because of the 16 inch wheels and the suspension.

As far as an N/A beating the 15 second mark.. I have an 89 GTU with a 3" free flow exhaust, fresh air intake headlight cover, k&N filter, Stock wheels, Dunlop SP5000's, and a Summit Racing switch to control the six-ports. Granted my engine was rebuilt by KD-Rotary, but its not ported, just rebuilt. With the subs and amps in the car my best time is 15.1 at Cecil County Dragway in MD, by dumping the subs, amps and the passenger seat and after adding the cool air inlet, i got a best time of 14.8 at 94.6 MPH on 100 octane.... I can beat a rustang off the line, but I've faced the facts that even a ported N/A isn't gonna take a rustang at the lights if the other guy knows what he's doing.

I have to agree with my GenIII buddies on this one... the only way to get truly fantastic performance out of the N/A's is to decrease your intake manifold vaccume....

by adding a turbocharger...... WHich I have mostly figured out... just don't know if i wanna invest the money in this car or buy a TII... or a genI and stuff 5.0 in it...

One final note... if you are going to try and hop up an N/A to compete with the big boys..... use an 89-91 engine block (better compression, six ports), chuck the OMP and run premix gas, port the bastard, and buy a Haltec, NOS, and a wideband oxygen sensor to set the maps... (unless you're one of those low tech carb guys, but with the Haltec, you can set a street map to save some fuel....) but always remember..... You MAY beat some of the mustang boys.... but If you go up against a GenIII, or a Supra... you'll just tick yourself off!

i agree, people need to be choosey of who they race, Na's will never be super fast strip cars, but they are not slow *** crates. maybe if somebody built a purpose built tube chassis drag car or some thing crazy, but why, these cars were designed for and are incredibly enjoyable in the turns. or sideways in the turns for that matter.

Basically the same setup that PP13BNOS, after tunning the SAFC on a real dyno with a real wideband, he got 167hp (or was it 169) at the wheel; 15.2 at the dragstrip with 95mph.

Listen guys I am in the same boat, I own a 91NA, and I want to make it faster........I know it can be done. I just don't like people saying my car feels like a 14 sec car, numbers speak for themselves.

btw.....wondering what exactly you are gonna do to "break the na barrier"???

Well, 15.2 is a respectable time for a N/A. That will prolly beat a S4 TII in stock form.


I konw my mods and hp are at least BALLPARK. There have been dyno runs of cars @ 153+rwhp with exhaust and intake (no porting). So it's safe to assume that's like 180-185. Now add intake porting and some small other cheap mods and 190 is definately attainable. Pineapple racing sleeves and a few other goodies and 200+ is more than attainable .

What mods are you running KNONFS? Have you taken your car out to the track yet? I will someday when I 1) get the money and 2) find the time to drive all the way to brainard (2-3 hour drive each way).

well alot of people think that you shouldnt dump your money into an NA,because its an "NA".there are alot of people being held back from makin their NA fast...ex:money,know-how,no rotary shops close,...blah
I'd actually like to see someone do something no ones really ever done in an FC...Non Turbo...make some sort of history or something....

RETed

My suggestion to all the NA guys who are getting defensive...
Get a ride in a "mildly modded" turbo and then make your comments...

peejay

Yes, yes it will.

The best thing you can do is add lightness. You get more gains from removing weight than adding power. Removing weight makes life easier on your tires and drivetrain, adding power makes things harder. Plus, removing weight also aids cornering and braking, too!


2210lb + 190lb driver + 130hp = the results in the right lane

Ive been reading these "NA's are slow" posts for as long as I can remember.Do you know what I find amusing? The NA guys always stand behind the same 2 defenses...reliability and handling. No one ever questioned the so called reliability of an NA rotary, so let's leave that one alone...let's talk about them being slow.

Everyone (NA owners) says it's OK that they arent that fast, and that that's not why they own an NA. They say they own NA's because of the handling. They say they don't care about drag racing...it's not real racing. They say they'd kick all of our turbo'd asses in the twisties or on the track.

My point? Read through all these posts with NA owners taking up for their cars and what do you see? Them posting their 1/4 mile times....not their track times or their drifting stories...their 1/4 MILE times!!!


Isn't that amusing, all the "diehard" NA guys who swear by the handling, not the acceleration....DREAM of their cars dipping into the high 13's! Why is that? I'll tell you why...they are in denial of their TURBO ENVY!

Seriously, I know there are some people out there who actually race their cars (i.e.--Silkworm), an that is very cool. But the rest of ya, stop the whole "we're too good for drag racing" bit. You drive your car everyday on the street...not Laguna Seca..You're not gonna find to many touring style races on your way to work.

I tried saying that last week. No one would take me up on that.

The reliabilty thing is funny. Almost all the people that bring it up wither have or need a rebuild. My garage queen maintenance hog TII still has the unopened stock motor in it

dre_2ooo

I have NEVER once mentioned reliability as why I own a NA. Hell, my engine **** itself at 108k miles, you call that reliable?

I konw ALL RX-7's have incredible handling. That's just the way it is. FB, FC, FD, all known for great braking and handling. They always dominate at the track reguardless of induction. They are made for and ARE great track cars.

RETed, yes, I have ridden in 13 and 12 sec cars. Hell, I even drove a V12 Brabus SL600 ($95,000 sticker) for a bit. Yes, they are fast as hell and I know my N/A is nowhere near that much fun in acelleration. But that's not why I own the car. I bought the car cuz 1) I'm a poor college kid and a TII is outta my price range 2) I love the rotary engine and NEEDED one, 3) This has been the ONLY car I've ever loved 4) It 0wNZ at auto-X and 5) it's got a "PURE sports car soul" and 6) you gotta admit, it's one cool car .. in all aspects.

I just get all riled up when fagotr0ns doubt my legitimate kills. And especially JoeD with his daddy's mercedes. And felix wankel calling 300ZX and Mustang GT's commuter cars just cuz I raced and beat em.

I just know this : I get one hell of a blast driving my car and that's all that matters.

Well shut the **** up about me then.

rx-7s rock

I have pulled 16.3 with my stock N/A. I lost the time slip. I know I have it somewhere but I can prove that I pulled 16.3 stock with about 32,000 miles. And I have the slow 2nd gen....I have power nothing! I say with a few good mods (full exhaust, intake, and street port) mid 15's to 15.6 is possible.

Are you another "robiferretti"?!?! You sure sound like one

Personally Im not a constant member here just yet until I get ahold of this 86 NA GXL. But this sounds a lot like the arguments we yousta have on the ZX2 boards. Cept it was mostly import vs. domestic.

I find it almost amusing you can all argue back and forth amongst eachother over diff generations and NA vs boosting. Now my ZX2 had absolutely no aftermarket support. Stock my car ran a 17.2. Modded a best of 16.4. Thas a 99' 2.0 ltr Ford Escort. Now we have gotten these NA cars down to around mid 13's and still street legal. U mean to tell me that u can't take down a NA rex a few seconds and stay streetable and NA? Has any1 ever tried boosting a NA? I'm just asking cause I know nuthing about rotary motors.

*sigh*,...well I've been trying to stay out of threads like these, I think that they are kind childish, but I'll break down and throw my $.02 in. I've owned my rx-7 for almost 3 years now, its a 86 GXL. I love the car to death, and have tons of fun driving it. I've ridden in 10 and 11 second drag cars, and while it was a blast being pushed back in your seat, the general feel of driving fun wasnt all there. Now, I will be the first person to admit my car is slow. Ill say it again, MY CAR IS SLOW. Now I think I could pull a high 14sec 1/4 with it, but since when is high 14's fast?? I could dump thousands into my N/A and *maybe* hit 13's, but I just wont. Why?? Cuz for that much I could buy a Turbo2 and lighty mod it and be 10X faster. Personally I wish I wouldve done a little more homework before I bought my car and waited to find a nice Turbo2, but as long as I have this Id might as well play around a little, have some fun with it. I've beaten my fair share of cars with it, V6 mustangs/ V6 camaros/ rsx-s/ even 1 mustang GT. But so what, all those cars are slow also. And if they had the mods on them that I have on my N/A they probably wouldve smoked me. All this argueing is stupid. Noone said that N/A's are pieces of **** or anything, they just said that they were slow, which they are. And a turbo will handle just as well as a N/A, if not better. Just have to be a little more cautios of boost hitting while your in a turn, but other than that just the same. And a FD will own most FC's on the track, even a FB would with a modded suspension. I just realized that I dont have much of a point, so Im gonna stop now

I run a 16.1 in my 'vert. Remember, the 'vert is 300+ lbs heavier... and all I have is a filter and exhaust.

I realize that some people live in areas where these things are still relatively expensive or very hard to find.&nbsp I think it's time to move...

There's no distinction between NA or turbo here.

Only one you owned?

Last time I checked, I think the Miata and MR-2 Mk I kicked it's ***?

You talking about an NA versus a turbo?&nbsp I hope not, cause however you slice it, the Turbo II is just an NA with a turbo motor in it...


I really don't drive my cars cause they are cool...

dre_2ooo

1) TII's are RARE up here
2) Agreed
3) I've driven a few other cars and owned a MX-6 before this one.
4) There are so few cars at the auto-X's up here in my class.... Last time I ran consistent times with an FD, but he was just learning. Never raced a MR-2 at an auto-x. Miatas are VERY comparable though .
5) No, not NA vs. Turbo, i'm talking RX-7 in general, they're all sports cars
6) Neither do I, but that seems to be the general synopsis around here

Blowtus

I've been in a few quick na rotes, and while I know it's possible with enough money, you still don't get anywhere near the driveability of a turbo... if that's not an issue for you then great. Starting off with an na if you're after straight line speed just seems bloody ludicrous to me. Unless you've got heaps of money to spare and like the noise or something...

wow, from the last time i checked this got really tense. I don't think my na is SLOW, but i agree, if i had a little more money , patience ,and researched it more, i would have for sure bought a tII. but i bought a super nice gxl, I love it, I love the way it drives, but Yeah I wish it was faster. I am sure that everyone that owns an na wants more power. I don't really want a turbo, i want to be different, supercharged and carbed. But of course that is not happening anytime soon cuz i'm broke, and i would want a peripheral port before the supercharger. Also, the floor will probably need redoing before that. i need to rob abank or some ****.

Come to think of it, i am pretty sure every rx7 owner, wether tII or na, wants a little more power. turbo guys just started a little higher up in power. going fast is an expensive game, in some places na is way more affordable
