Relatively new to RX-7s

So lately I've been looking into RX-7s and I found that the FC is much cheaper than the FD, why is that? What is the difference between the two? I'm looking into buying an FC. I'm pretty sure the FC will be faster than my Celica GTS . So are the FCs pretty fast? Slow? How can I upgrade it to get really good times on the 1/4 mile, or enough to kick a Prelude's ***?

FC N/A are slow as hell. An FC TII is crazy fast with small mods.

No honda can beat an FC TII if its not turbo.

FD is overpriced imo and always breaks down.

A lightly modded TII can burn a stock FD.

FC has lower compression rotors, has more potential has far as power.
FD has a GREAT suspension

well its kinda of like the mkIII supra's (86.5-91ish) to the MKIV supras (93-98) they are just two different cars... you can get FD's at decent prices if you look around but finding an fc will always be cheaper... gts celicas are pretty quick but an turbo II or street ported fc should keep up or pass depending on the situation

Yes, Richmond thread in the NE forum https://www.rx7club.com/ne-rx-7-forum-30/richmond-va-rx-7-owners-143677/
Also we have a local rotary mech, Richard mitchum owns a company just of Midlothian called Mitchem enterprises; he's got a bunch of parts cars, builds E-Production class race cars and is the head Tech inspector for NASA-midatlantic
he doesn't work on FD though
Jay is the local for that, used to work at Delta V on Boulevard but has moved on

come down to one of the regular Friday night meetups at the Starbucks on Forest, there is always a couple of 7's https://www.rx7club.com/ne-rx-7-forum-30/weekly-richmond-va-friday-night-starbucks-meet-new-location-533164/

be warned we're not all about drag much, mostly autocross, road course and of course drifter guys
the meetup is a wide variety of people and cars hanging out and talking shop, no stupid stunting and we wanna keep it that way, we have no popo problems and have the permission from the owners to be there

You're comparing two different generations of RX-7, thus the price variance. (FC=2nd generation, FD=3rd.) That, and multiple other factors. There is no "better than", thats just opinion, and you will get different responses as far as that goes. Differences are easy to find by searching the FAQ sections on the 2nd gen section, and 3rd gen.

FC's are a great platform, non-turbo FC's are not "fast" depending on your definition of the word. Fun yes, the FC platform in general is a great overall car. If you want to have a "fast" (as in 13's or faster in the 1/4) then the easier route to take is getting a Turbo II variant of the FC.

Before you go out and purchase anything, you should research and read literally everything you can about these cars. Look at the factory service manuals, read posts on here that deal with common problems, and everything else you are interested in. There is a plethora of knowledge here. The best thing in my opinion that you can do before purchase is to research and have a general knowledge of what you are working with, and dealing with before jumping into something.

I think a Turbo II is a great car, and a more than fun car. You just have to find one that fits your price range, and is in the condition you need it to be in depending on your experience level. Its better to pay more for a better example of something, than to pay less and end up putting just as much into it in the long run....

Check the FAQ first. It will define most of the acronyms you see in the Archives.

FC = '86-'92
FD = '93+

Two totally different cars.

Omg i don't know where to begin..

First yes there are a crap load of motor swapped Honda's that can spank a stock t2. Now mod alittle and well we all know what will happen.

FD is actually the cheapest it's ever been hell i just seen one on here the other day for 9k and it ran! And if you do regular maintenance it will last just fine. It's usually the previous owner's that neglected the FD's maintenance because they didn't know what to do.

And finally how lightly modded are we talking? bolt on's? I don't think so. Maybe with full exhaust/intake and a little extra fuel then yes they can.Remember an FD has way more top end its not just about 0-60.
