FC RX7--what do u guys think?

[teggy 2nr]

im planning on investing in an rx7, ive heard alot of bad things about the rotary so i just want to know what people think? RX7 owners?

[SampaGuy]

my friends fd blew the engine... and it was like running perfect, next day it blew. no warning at all. i dont trust rotaries but the FCs sure look good

[EJ25RUN]

OK, rotories can be fun but take special care

#1- never run lean = death of motor

#2- detonation is bad in any motor but is catasrophic in a rotory.

#3- overheating is a serious concern, espically in the poor design of
fd rx7 radiator position.

#4- tune with any bolt on. even a simple downpipe or exhaust job can lean the motor to death.

#5- finding someone who specialises in them. (like it says)

do your reserarch, if you are serious about buying an rotory you must go through most of the stuff yourself.

IA isnt the place to get this info, thats for sure.

thanks alot, i noe a guy who specializes in rx7's

87 GXL is N/A - they are notorious for lasting forever and not blowing up easily.
The heat from the turbos are what shorten the life of any turbo car - rotary or otherwise.

cool!! good info!!

Used to be Mazcare (Marrietta) that was THE rotory specialist, but last i herd there Great mechanic "think his name was bryan" left, other place i would take it is Balance Performance.

My roomate got his FD to 77k before the apex seal went out on it, though probably his fault cause his 2nd turbo had died on him and he was still driving on it :shrugs:
It's nice though having one in your garage

MazCare is a great shop, and does quality work.

Your friend's second turbo probably was ok, but the TCA was probably bad. Very common problem. Happened on mine as well. You can drive on it, but it's better to lock it open if you are going to. I'm guessing that he didn't know to do that.

FDs are by far the best RX7 built...so get a FD dont; get a FC

^^personal opinion. i think that the FD is for a more serious rotary tuner if your buying one to mod. i love the FC. its light, simple, and not that costly to mod. if its going to be your first rotary id get a NA FC S5 (series 5) GTUs. its light and already has the TII trans and LSD diff. reason i say that is the NA trans is CRAP! it might hold 200HP or less it you have a strong clutch. i broke my trans with only 135hp with a street/strip clutch. if you get a NA and later want a turbo you can either swap to a TII motor or turbo the NA (if the miles arent that high). heres a excellent link to the full write up on turboing a NA http://www.teamfc3s.org/forum/showth...threadid=37694. you should check out nopistons.com Rx7club.com and Teamfc3s.org (if you havent already)

My God, I haven't posted on this thread yet?

I just love reminscing about the past!

:]

My first rotary:

'88 Turbo II RX-7









It was clean as hell. Ran GREAT. Great starter mod-list when I got it, and it was surprisingly fast for 10psi on the T4 turbo I had in it. Super nice interior for a late 80's car too. I loved driving that car. Only problems I ever had for the year+ I had it, were old-car related...pinion diff seal, diff mounts...that kinda stuff.

Next up:

'93 RX-7 Twin-Turbo Touring/R1









-----------------------------------------------------------------------------

Looks great...torquier than the FC...amazing interior and stock BOSE system (part of the Touring package). Overall, it's a VERY fun drive. The OS Giken twin-plate clutch + short-shifter in mine, are a little much for daily-driving though.


In general, I do feel the FC was much more reliable. And with the added help of removed emissions, it was surprisingly easy for a not-so-mechanically inclined person such as myself, to work on

In general, FD's are EXTREMELY expensive to not only maintain, but also difficult to work on. The sequential system for the stock twin-turbo's is rediculous, thus I went non-sequential. Even beyond that, they have so many more flaws, STOCK, regarding cheap/poorly-effective parts, that in themself, damn near REQUIRE upgrading. The stock computer is unforgiving when working with aftermarket upgrades, and pre-detonation as well as fuel-cut are a strong possibility, even at stock boost level on a cold night if you're not careful. The stock radiator has plastic end-tanks, and is prone to basically taking a dump after some time. Also, the stock "Air-Separation Tank", which is like a baby coolant resevoir that basically burps air bubbles out of the system for you, is PLASTIC....and with all the generated heat produced by that motor, along with the 99% plastic vacuum lines...are EXTREMELY prone to becoming brittle and simply breaking. That in itself can cause MANY 'sudden-death' moments for the motor.

In general, again, I found the FC was much more SIMPLE, and easier to work on. Thanks mostly in part to the stock SINGLE-turbo...which is why about 60% of FD owners go single-turbo. Simple, space-reducing, and predictable.

In general, an FD is a HORRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRIBLE choice for any first-timer rotary, and/or RWD-er, or first time turbo-driver. Without ANY form of experience in any of those categories, the 'joys' OF owning an FD, can be easily abused, because shit...it IS fun to drive.

Look...if you want an RX-7 that badly, pick up a clean 89-91 RX-7...N/A or Turbo II is allright. The 89-91 body-styling and interior changed for the better over the 86-88 for sure. They look GREAT, and still have massive potential.

Take a look:





If you've at least done some considerable research regarding general rotary maitenence and "Do's and Don't's" then either a N/A or T2 is a great first-time rotary vehicle, In my opinion, an FC makes for a better teacher of how a rotary engine works..and is great preparation for owning any other rotary vehicle. But again...even going from a Turbo II to a 3rd gen...you're talking a WHOLE different monster..FD's require ALOT more maintence, and the motors are alot more 'fragile', initialy...without proper care. Modifications like an upgraded intercooler, radiator, air-separation tank, and aftermarket ECU (chipped, piggy-back, or standalone) are great, not only for increasing horse-power and tunability, but for even increasing the longevity of the motor by increasing the actual effectiveness of the 2 most important things that keep a rotary engine running strong: One, running cool. Two, running at appropriate air/fuel ratios as to prevent pre-detonation, fuel-cut, and general fuel-related problems. Those are the two biggest killers of rotary engines. And no, not all fkin' rotary engine blow at 40k, 50k, 60k miles. It's ALL about how they are maintained throughout those miles. Period.

Look...I've already typed like half a page.

If you want ANY RX-7, just go to www.rx7club.com and www.nopistons.com and just READ READ READ.

I'm spent.

Thanks for your time, guys.

I hope I was informative.

RX-7's suck unless they have 8 pistons... or more than 2 rotaries and driven only once a year... or unless they're in an animation.

i dont know about an FC, but an FD can take a full exhaust and intake with the stock ECU due to the rich settings. but i agree with all of the above, and i own one (but maybe not for long, theres a soarer that caught my eye)

NA to NA a piston motor could NEVER take the abuse a rotary could. adding boost is when the rotary's life starts to fade.

[Kalifornia087]

Buy One. Now. I just bought my 88 GTU Thursday and the reason i did.... I fell in love with it after test driving it. Great car. When teh rotary blows i have a 302 that will go in it, so im not worried. But seriously, AWESOME CARS

Take a look:

im in love!!!!

[K24cb7coupe]

I had a fc and i was a great car is sold it so i can get an fd, but i want a bone stock R1.

NA rotaries are slowteries. Just ask any rx-8 owners about getting 0W(\)e([

[AE86 Dorifto]

Rotary engines can last amazingly long if you take care of them properly. My friend has a white fc but it's just too bad he's a dumbass and has never checked his oil even once. It's only been me and my brother taking care of his car. But the thing is really fun. It handles amazingly and stays in total control when it's sideways.

P.S. Do a whole bunch of research before going off and modding it.
