FC RX7 specs...N/A reliable???

mk3mann · 10-14-2004, 12:02 PM

hey guys, well my mk3 turbo supra is up and going, i dont want to put alot of miles on her...so i need a daily driver.....a fun one

first, i want a FC rx7, are the NON turbo's reliable at all?

what are the differences b/t the non turbo and the turbo?

what motor did the non turbos have in them?

what were MAJOR flaws or problems with that series of rx7?

heck, all i knwo is i want one....and what should i look for in one?

thanks so much guys,

Jonathan

NA's are very reliable, put a nice full exhaust on there and that will give u a good hp jump up. Boost is a factor that tends to lessen the life ina rotary, but do the regular oil change, spark plugs (i change them every 6 months) and any other stuff and u will be just fine. If u can find a 89-91 model they are newer and tend to have alittle more hp, a GTUs is basically a turbo model without the turbo so u get a nice LSD. The engine is a 13b. It would be hot to run a nice individual throttle body on the intakes. That would clean up the engine signifigantly. But anymore questions just ask

Ghost of Duluth · 10-14-2004, 01:09 PM

Agreed. N/A = long Rotary life, Turbo = short, cussing, hair pulling out, short lived fast death.

turbo23 · 10-14-2004, 01:20 PM

Turbos are good to, just most people mod stupid dont get the right tuning and pop. You can build a strong turbo FC and easily have it last 80-100k but after that any car no matter piston or rotary isnt gonna be worth *Censored**Censored**Censored**Censored*

Darkstar · 10-14-2004, 01:41 PM

Ahhh... I don't know if you know tat, but Ghost personally has an FD which has made him some problems. And I wouldn't say that he had it tuned in a wrong way or with some bugs. It just depends on a motor, it won't go beyond it's limits. You can make it reach it's limits later, but it surely will die sometime if you don't rebuild it after some time.

NA's are definetely more reliable than turbos. I suppose that's because of rotary engines tendency to overheat (mostly FD I suppose), and the turbos making the temperature even higher.

turbo23 · 10-14-2004, 01:46 PM

Well FD motors just require alittle more attention, i beleive he was still twins, which creates alot of heat, but if he were to go single, with a large radiator, and a vented hood he would be fine

What is the quad rotor set up?
where do i get one from? I have a video of the SCAT 4 rotor fd.....pretty hot eh?

lol...

i just want a good fun car for backroads....and highway miles...

how much do you think i can find a decent fc?

turbo23 · 10-14-2004, 03:32 PM

quad rotor is basically race oriented only, ive pretty damn expensive and not intended for daily driven street use, considering some 4 rotor aplications can get u 700hp NA

i love the way they sound though!

lol...

what motor is the N/A rx7 motor have ? the 13 B 2 rotor?

Cobra_R · 10-14-2004, 04:54 PM

yea its a 13 b 2 rotor.
Im selling my NA FC convertible if your interested.

240drftr · 10-15-2004, 06:05 AM

700hp n/a

turbo23 · 10-15-2004, 06:12 AM

just imagine with a large turbo setup, possibly a 2 big turbos. Can someone say 2000hp?

NismoSigma · 10-15-2004, 06:45 AM

:O~~~~~~~ Plump buttery goodness!

2000HP? Good lord thats alot from a rotary. Wouldnt that just make the engine last like 2 hours at most?! LOL sounds like the engines that they used to use in nascar, back a couple of years ago. For qualifying they would sacrafice an engine by using water instead of oil, you got alot of less weight and you got one hella fast lap, but you lost an engine! :P

Darkstar · 10-15-2004, 11:03 AM

In Hurley Engineering they make custom 4 rotor NA engines, which are composed from 13B parts and a custom eccentric shaft. The power outputs are going to be high, but not as high as 700HP. Remember that Mazda787B racecar had an R26B NA quad rotor (Jesus, now that's some kind of nice machinery), which had variable intake length, and it posted around 750 at the flywheel. I don't think that it's going to put THAT much in a street car... Considering the fact that guys in Japan can pump 350 NA horses from a 20B with turbos taken off (example: JGTC Amemiya Aspara Drink RX-7), it shouldn't be a problem to go over 430 in a quad rotor. The guys at www.4rotor.com have an RX-7 quad rotor project car. It's going to be a monster, I'm telling you...

well I thought about staying with Toyota and getting an old school cressida and rebuilding a 7mge ( non turbo) motor for it...torque....but 4 doors on backroads dont mix that well...or maybe in the case of the cressida there is an acception....

I ahve always loved the FC rx7...and i dont care for the turbo...thats just if you want to blow it up soon

..

I am going to TRY to get a hardtop ( NO sunroof at all)...n/a...i want fun every day driving

Darkstar · 10-15-2004, 01:42 PM

You could always get a first generation non-VVTi twin turbo 1JZ

mk3mann · 10-15-2004, 03:02 PM

yeah....thats true.

mk3mann · 10-15-2004, 03:17 PM

but the conversion is pretty hard....being wiring and all...and banging out the firewall too....lol

but the 1jz aftermarket parts are rare in the states and VERY expensive...and the bottem end is good only to 500 whp...the 7m is a little more stout....but has its hinderences too

SidewaysGts · 10-15-2004, 06:35 PM

20b is an awesome engine, they make cose to 280 hp stock on twin turbos.. removes the turbos you get 250 hp NA, says a lot about those turbos doesnt it? japan has this magic numberthing.. dunno what or why...

Basicly port the 20b engine a bit 300+ hp na is easy enough to get, or keep the turbos and do some basic turbo work (intercooler upgrade better radiator up the boost blah blah) and your looking at a good 5-600 horsepower easy.

I concur on that point!

but i didnt think that the turbos were that bad!
And i didnt even know you could make such a powerful n/a rotory!!!!!!!!!

this is some good info...and food for thought....next project here i come

sideway5daze · 10-16-2004, 09:07 AM

i got a n/a fc and mine is overheating

SidewaysGts · 10-16-2004, 08:02 PM

Not that the turbos on the 20b suck, just such low boost i believe.. then again i dont have one so i cant say for sure; just going on what ive been told.

Darkstar · 10-17-2004, 01:23 AM

I would say that those turbos are great... In a stock car, they're pumping much less than 1bar (14psi), so using about a quarter of their potential. I've seen one RX-7 (it was in hte Import Racer mag) with a street ported 20B swapped in, stock turbos, and custom intercooler and radiator. Result? 550hp...

it wouldn't happen to be the Pettit Racing FD track car would it?

4 rotor engines arent bought nor you can buy them, YOU MAKE THE DAMN THING. these engines are custom made by a company. pretty crazy idea but it works.
