I Wanna buy + build an FC~ HELP new to scene

['87 Turbo II]

ok time out for a noob
13b-rew = fd?
13bt-rew = fd turbo?
if this is tru i thought the fds were twin so wouldnt it be 13btt-rew?

13b-t = trubo fc?
13b = na fc?

t2 = turbo2 = fc turbo = 13b-tf


can someone correct mistakes and or tell me if i got it right?

well there is no such thing as a 13bt-REW. All FDs were 13b-REWs so the "T" is understood, that's why there is not two "T"s (I don't quite know what REW stands for but it has something to do with the twin sequintial turbos). FC Turbo II (two) are not, as many would think, twin turboed but rather it's the 2nd model in the Rx (rotary experiment) line to receive a turbo, so they added "two" however, it is the first american spec to receive the turbo and 87 was the first year of the turbo.and FBs can be "12a" or "13b" 13bt IS the turbo FC and 13b is the N/A FC. I have no idea where you got "13b-tf". Also for a little more speculation There is another rotary line in Japan, the Cosmo. They came with either a 13b-REW or a 20b (the 20b was also twin turboed but there was no N/A or single turbo edition so once again the TT is understood)

hey thanks for the help. one thing i never heard of fbs (gen before fc's)i thought they were called sa's thats we called them in japan. differnt chasis in america? and one last question so if all fds are 13b-rew then all fds are turbod is this correct?

 

[smo0f]

FB = 1st gen, not sure of the year range but it went up to 85, maybe started 79. the 13 B FB's were modeled the 'gsl-se'. There were other models like 'gsl' etc. Only the gsl-se had the 13B engine, and was produced in both 84 and 85, which uses EFI (fuel injection). Previous versions used the 12A motor, and that was carbu'd.

yeah all Fds are turbo. and I thought the Japanese name for the FC was the Savannah Rx7 so was the FB also called savannah or sa?

i just know we always went by chasis names over there, and since everyone called them sa's i thought they were sa-somthing. but if there fbs thats kool just never heard them called that

well I think it's unnoficial but on rx7club.com we call 1st gens FBs, 2nd gens FCs, 3rd gens FDs, and some people are trying to pin FE on the Rx-8 but it's not too popular.

 

[SybrFreq]

fb = sa22
fc = fc3s
fd = fd3s

 

[SkinnyJoint]

fb = sa22
fc = fc3s
fd = fd3s

there we go sa22 so why the **** would ppl call them fbs...

 

['87 Turbo II]

there we go sa22 so why the **** would ppl call them fbs...

because it makes it apattern that's easy to follow, and we as a race are lazy people.

 

[KatakanaKarl]

In Japan, all 1st gens were SA22's. In the US, the earlier model 1st gens were SA22's, but later ones had the FB VIN codes.

So, technically (as far as US RX-7's go), some 1st Gens are SA22's, while others are FB's.

I gotta read up!

Karl's Guide to Mazda Rotary Engines (Thanks Wikipedia and RX-7 Club):

40A: Prototype single rotor based on early NSU KKM400 design. Never produced in volume.

L8A: 789cc engine used in early Cosmo prototypes.

10A: First Mazda production rotary engine, used in production cosmos. 982cc.

13A: Rotary engine designed for front wheel drive applications. It was only used in the R130 Luce, from 1969-1972.

12A: One of the most successful engines for mazda. Used in many Mazdas, from the RX-2, to the first generation RX-7s. It was the first rotary engine to feature the 6-port induction system later featured on the 13B. A turbo version was available on the Japanese model RX-7 as the highest level engine.

12B: A single distributer version of the 12A.

13B: The most successful Mazda rotary engine. Came in numerious varieties:

13B-AP: Designed for better emmissions and power. Used in REPU (Rotary Engine Pick Up)

13B-RESI: Rotary Engine Super Injection, a fuel-injected engine used in high-trim level GSL-SE 1st Gen RX-7.

13B-DEI: Dynamic Effect Intake, used on the US model NA 2nd Gen RX-7's, had the 6PI system as well.

13B-Turbo: Based off the DEI, but without the 6PI system. Turbocharged, made between 185-200hp. Found on Japan market 2nd Gens, as well as US model Turbos.

13B-RE: Twin turbo engine used in lower-trim Eunos Cosmo.

13B-REW: Twin turbo engine used in 3rd Generation RX-7.

20B: 3-rotor engine used in Mazda 757 and 767 Le Mans cars. Originally named 13G, name was later changed to conform with Mazda's engine naming convention.

20B-REW: 3-rotor twin turbo engine used on high-trim level Eunos Cosmo. Holy grail of rotary engines, but VERY expensive. Also difficult to rebuild, due to two-piece eccentric shaft that requires a special tool to remove.

13J: Early 4-rotor prototype engine used in 767 Le Mans car. Proved unsuccessful, and had to be redesigned.

26B: 4-rotor engine from Le Mans winning Mazda 787B. 2.6 liter, made 700hp at 9000RPM. The engine used variable-length intake runners, and had its internals cermet coated to reduce wear. The 787B was the only Japanese car to ever win Le Mans, and the 26B was the only non-piston engine to win.

Renesis: 13B derived engine used in the RX-8. By moving the exhaust ports from the rotor housings to the side housings, exhaust overlap is eliminated, provided better emmissions and gas milage. Uses throttle-by-wire system, three-way variable intake, and 6 fuel injectors to maximize power and torque.

sa22 (12A Carburator)i beleived went from late 78 to late 82.
a remodified fb (12A CARB and GSL-SE 13B on 85)from early 83 to 85
fc Series 4 86-88 (13B N/A 86-88, 13BT2 87-88)
a remodified fc series 5 89-91 (92 in japan and some here in US too)(13B N/A & 13BT2)
fd 93-95 in US and continued till 2002 in japan (13B-REW wich is TT or Twin Turbo)
the cosmo has been going on and off since the 60s. its had engines from the L10 1.0 litre engine to the great 20B twinturbo.
the cosmo also had a 20B all motor,a 13BRE twin turbo and somewhere along the 70s it also had a 12A.

i dunno if you second gen owner have noticed but if you remove that fan clutch cover you get a hell lot of space. EVER WONDER WHY?

WELP, the FC or second gen Rx7 86-92 was originaly designed to have the 2.0 liter 20B twinturbo engine. However, CRAPPY emissions n regulations here in the US would not allow it so it got stuck with the 13b or 13B turbo2.

I don't own an FC, but I have noticed the space you talk about on a few that I've seen with electric fans. I always wondered about that but figured it just had to do with putting the engine weight behind the front wheels.
Also, weren't most Japanese manufacturers limited by some sort of max horsepower output?

 

[FC3Cturbo]

You know why that huge space is there..... not because it was meant to have a 20b (cause it wasn't) is to keep the weight distribution to the best possible ratio. The 20b one that you are speaking of would have been an "upgrade" available. And I'm glad it didn't come with one, otherwise you'd see 50million FC's with 20bs running around and a ****** would be nothing special.

I have heard that the max hp "law" that japanese auto makers had was never actually a real law. It was established so that they would not be killing each other trying to make ungodly amounts of hp to keep in touch with each other performance, I.E. 98' Rx7 vs. 98' SupraTT. 280ps each (at least thats what they say they come with..) But we all know that the flick of an EBC can add an easy 20-50hp with the right supporting mods.

 

['87 Turbo II]

The 1990 GTUs were supposed to house the 20b but the project failed to launch because of cooling issues.
