FC RX-7 Vs. S13 240sx

[Gman]

Since the search button isn't working for me, I got a question for you guys. &nbsp;These two cars are evenly matched when you compare them together. &nbsp;FC Series 4 motor vs. SOHC KA and the Series 5 vs. DOHC KA seem to match up pretty well. &nbsp;Balance for the FC is 50/50 and the S13 is like 52/48 or seomthing. &nbsp;Anyway, do you guys/gals have any experience with both of these vehicles? &nbsp;What were you impressions? &nbsp;Personally, I have been looking for black S13 FB, but I can't find too many here in AZ. &nbsp;Then i began looking at N/A RX-7s and they seem to be pretty good cars. &nbsp;Pretty reliable engines when maintained and 13BT motors are pretty cheap if it blows up on you. &nbsp;Any opinions are welcome. &nbsp; <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/cool.gif" border="0" valign="absmiddle" alt=':cool:'>

i used to have a 88' fc3s turbo 2 before i got my 91' s13 FB and i loved it!!! that thing hauled ass like a mofo and killed all who opposed me and even went 140 mph racing an accord, golf, integra, corolla, and a 240sx!!! my 91' FB is my pride and joy as of now and i think with a turbo upgrade, it should be even better than the rx-7 IMO but both cars are greaaaaaat!

i drove my friend's '86 NA, and that thing was a hoot! first thing i noticed was that the tach was in the middle of the IC. and u know that any car with a big ass tach dead smack in the middle of the IC is built for fun! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'> &nbsp;i loved the responsiveness and light steering in that car, plus it was light as hell.

The FC is a fun car to drive! Plus the engines are relatively easy to rebuild ( i have done 2). Ive said this before, if i didnt have my s13hb, then i would have an 89-91 Turbo II FC!

<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'> my friend has an FC with Air intake, Racing Beat headers, and HKS twin exhaust..we would always race with my Datsun 510 (R.I.P). I always had him on start off but he will eventually catch up like a ROCKET! Now I sold that datsun for an S13 coupe, w/ straight pipe to Remus exhaust(loud). Everything else is basically O.G. Once i got the car, i wanted to race him but the bafoon wrecked it in the mountains. now he has a 89 FC GXL which he transplanted his engine to and would have the car running by tomorrow <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/hmmm.gif" border="0" valign="absmiddle" alt=':hmmm:'> &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'> .

So i'll keep you posted who is gonna win!

[Gman]

Thanks for the reply guys, I think I will most likely get the FC. &nbsp;I love the fact that it revs to 7k + and they respond fairly well to basic mods. &nbsp;Just want to say i got nothing but respect for well built 240s &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> &nbsp;

Coolerow, let me know how the race goes. &nbsp;I'm interested in seeing which car would win in a straight line race. &nbsp;Do you have the DOHC motor? &nbsp;Which motor does your friend have? &nbsp;Series 4 or Series 5? &nbsp;(1986-1988 146hp Vs. 1989-1991 160hp)

[blink0r]

Best race....

My '91 DOHC 240sx VS my friensd 1988 RX-7 GTS (n/a)

My 240 is supposed to be faster in the 1/4 mile by about .4 tenths of a second.... everytime we race there's a different winner due to driver error. Even handling, these cars are simply too close to compare. If i had to buy another car, i'd get the FC TII <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'>

FC's are very good cars performance wise. In NA form, with the 13b engine, they give spirited performance.

The 86-87 have the 140hp engine, the laters ones with 160+ or so. If you going to mod it, get an earlier car, your going to end up with the same amount of horsepower either way N/A.

Put on some headers, a good flowing exhaust (stock exhaust is crap, very restrictive), and intake and you'll have a fun machine. They respond very well to mods.

The FC turbo II are fun too. The 87-88 have a bit less power, but they are also lighter.

Whichever one you get, make sure you change the oil every 1500 miles or so and keep those plugs clean.

Not entirely true. The later engines have lighter rotors that let the engine run up to 8000 RPM, and that is what gives it the extra ponies...so get the later ones. Oh and try for a GTU if you dont get a Turbo. The gtu is the sportiest non turbo.

kewl, Gman i will...

All i know is that the poor bastard is gonna cry after i humiliate his FC with my S13! I'll even try setting up an inboard camera pointing out my rear window, cause that's where he's gonna be..."trying" to catch up!

[samiam]

Well, I know I here alot of good things about them from everyone here. The rx's are and can be a pain in the ass especially when you start to upgrade, i.e. turbos, exhaust, intake all that stuff. Those cars unlike many other turboed vehicles are very responsive (negatively speaking) if the air/fuel is just a little off. And the 'snake pit' as many call the vacuums and wiring is a pain in the ass also, but on a plus the only thing you usually blow is the apex seal and you can replace that easy. You'd have a better chance w/ a 240sx. The rx are not as reliable for daily drivers. I've been working on them for 5yrs. Don't get me wrong I thing they're bad ass and love the styling. But too much of a pain.

PISTONS are better than Rot-Whores!

What I meant was that the earlier cars had less horsepower, but they also weighted less, I believe 200lbs or so. Stock for the stock the later cars and earlier cars would be pretty much equal. However, if you mod up an earlier car you will surpass the later 13b's hp, plus have a lighter car to begin with. Better power to weight ratio right out of the box after mods, without stripping interior, insulation, etc.

The GTU is basically an N/A version of the turbo II... better brakes, lsd, etc.

Before you buy an N/A FC3S, remember that these things have NO TORQUE. I mean, literally no torque... you can rev and rev and rev all the way up to 9k rpm, but you still won't get any torque. The DOHC KA is 155hp and 160lb/f (? or was that reversed) wheras the late FCs were 160hp and &nbsp;about 130lb/ft... or is it nm... shit... anyway they're fast cars and beautiful (i like their styling a lot, reminds me of Porsche 944s, yet not quite the same) but if you're going to get one, try to get your hands on the '88+ Turbo II.

My '93 240 pulls harder than my friends '91 convertible, but then again there's a ~400lb weight difference, and I've got heaps more torque.

Ideally, you'd find a cheap FD3s (1995 R2), but by the time you found that, I'd be driving it. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'>

The ugly snake pit that you have on the rotory engines (million vaccum lines) can be all cut down to about three vacuum lines if you know what you're doing. &nbsp;I know a rotary guru that used to build the engines for mazda and he told us that other than the restricitve intake and exhaust and any other fuel problems that you might encouter, theres no reason that you can't run a rotary engine up to 10,000 rpm's on the stock motor. &nbsp;My buddy does that in his first gen and that thing kicks ass( and its loud as hell too) &nbsp;because its bridgeported with a holley carb installed.

[NOSfEDs12vh45dett]

RX 7, is a good car only in the Turbo guise, then you get the best of both worlds, HP and torque, although, get a series 6 FD the only way to fly.

[samiam]

Okay, I have to admit if you bridgeport those suckers and eleminate some of those vacuums and lines. Then it'll sound like a domestic and tear up some chit on the road. But, we're talking bout regular people that basically don't understand that much into rx's it takes a while to get the basics and tuning on those rockets. I saw a bridgeported x7 from Okinawa a while back....and I must say, it was sexy.....for a Mazda.

[junia]

Back in okinawa I saw a first gen with a 13b carb turbo. &nbsp;That thing was bridgeported and the owner was just sitting there revving it hitting over 9 grand on the tach with easy. &nbsp;That motor went from 0 to 9000 rpm in an instant.
