I said I heard, and I mean 12's as in 12.0. In street trim, pulling 1 G. I dont know too much about rotaries, and I'm trying to learn. I'm sorry if I'm coming off as some big shot..... the problem is, at my HS, there is almost noone who knows anything about any cars, and alot of them ask me questions, and ask me to teach them alot of stuff. so I guess subconciously, I kinda feel more like a teacher than a student.... I need to tell my friends to bug off...
and I'm 17. and no, my parents dont give me tons of money, I work for what I have... even though my dad wants to be involved (physically and financially) with my project RX-7.
also, dont tell me I am too young, I have been driving since I turned 15 (whenever I went somewhere with parents).

Making big plans for your RX-7 are fine and dandy but learn the basic first. Learn how to make a stock engine "Be all it can be"(quote stolen directly from the US Army). When you have the basics down go on to the bigger stuff. I personally don't think I need a turbo charger to have fun in my car but others will tell you its the only way to go. Make your own decisions after you know more about the car in general. You'll be much happier knowing exactly what your car has in it, not what someone tells you it has in it. Are you confused now? Sorry if you are.

Good Luck.

I thought it was the acual block that mattered for compression and turboing an na.

sinfestboy

actually, Im not confused. I understand what you're saying... and I think you're right. I have been looking at some specs, dynos, etcetera etcetera, and I am realizing that I dont really need to go that far with my rx-7. and even If I do end up doing it in the far future, by that time I might as well just get an FD. I'll settle for a TII

The thing that "flipped my switch" was this:
I realized, that in my hurry to create some totally awesome killer street machine, I would be skipping a very important, and very fun part of the process. Making a reletivly puny engine a beast, is a very fun process. I also solved one of the great mysteries in cardom.... why do legit honda fans like hondas so much? because hondas suck. thats why. and when they make something that sucks into something great, is quite an accomplishment that not many people can claim to have acchived.

NZConvertible

This is a silly attitude. You may not like Hondas (I don't like them enough to buy one either) but that doesn't mean they "suck". Hondas are some of the best engineered cars on the planet, something you would realise if you did a little research. You can hardly say a 100hp/litre piston engine that meet all required emissions and noise requirements "sucks". Stupid people may do stupid things to their Hondas, But I've seen some shocking looking RX-7's too!
Sorry 'bout the rant!

InfiniIIIREX

series 5 NA engines make 123hp per liter

NZConvertible

I said piston engine, much harder. The S5 engine would also fail all current emissions requirements today.

I say, go get a R100. I just saw some of them run at the IDRC at Palmdale, CA. Oh my god.....crazy ****.

Congrats to Ari Yallon and rx7.com to his awesome victory in Street class.

100 hp per litre is impressive, but the fact that top dogs at honda wanted it to be WWD (wrong wheel drive) says alot about the people at honda.... also, its 200 bhp, factory claimed. it actually gets 170 whp, at 7700 rpm. the car is horrible, it doesnt even have 100 hp till 4500 rpm. oh, and to say more about the people at honda, the morons didnt even put a LSD on it. makes me sick.

NZConvertible

Please tell me what 200hp FWD LSD-less Honda you're talking about? There's more than one Honda you know...

sinfestboy

RSX-S. the prelude is 2.2 litres. thats not 200 hp per liter just pointing it out.....

NZConvertible

I said 100hp/L, not 200.

The Integra marketed in Japan, Oz and NZ has an LSD.

I was referring to the 160hp, 1.6L motor fitted to Civics and Integras in the same countries throughout the '90s.

I completely forgot about the 236hp, 2.0L RWD S2000, that's 118hp/L. Definitely designed by morons...

sinfestboy

and, like i said already, peaky *** powerbands. no power under 4500 rpm. but back to rx-7's.....

FPrep2ndGenRX7

sinfestboy said - and, like i said already, peaky *** powerbands. no power under 4500 rpm. but back to rx-7's.....

Thats funny. You just described a PP 13B N/A.

sinfestboy

PP? and whats a PP?

FPrep2ndGenRX7

PP = Peripheral Port

I thought everybody knew that.

importboi22

lol you just said peaky *** powerbands sorry but rotories with a BP or a PP are kinda just like a honda no power till about 3700rpms... and on a turbo lude they have about 150 hp at 4k rpms at 8.5psi. if you dont wanna a peaky *** power band get a v8, but if you want to rev a lil to get power and have updated technolgy stick with import..... and btw hondas are a great car i dont wanna hear anybody doggin on them cuz you dont see the honda peeps dog on anyone why should it be different here?

84 J-spec engines ARE TURBO... Just so that you will know 84-85 gsl-se were 13B for U.S. BUT in Japan those models were turbo instead not too many but they exist. We got two of those engines running around in the family (Both my cousins have GSL-SE with 1984 13B Turbo engines).

NZConvertible

The 84-85 (Series 3) RX-7 Turbo had a 12A, not a 13B. The 13B was not turbocharged until 1986 in the S4.

From www.monito.com:
P132 or GSL-SE Model 84-85
The SE saw the re-introduction of the 13B engine, last seen in the 1978 RX-4, but now rated at 135 bhp because of Dynamic Effect Intake (DEI), six port induction (2 by 3), and electronic fuel injection. In Japan, there was a P132 with a 12A turbocharged engine. Power steering was offered for the first time. The interior was upgraded, but this did not appear in the Japanese turbo version.

the S5 motor is 13 yrs old for christ sake, give it a break, compare apples to apples - S2000 motor to 13BRenisis - now you are on the right track

Yeah, but InfiniIIIREX brought the S5 engine into the comparison, not me. My point was (and still is) Hondas are not crap. I just don't want one. Well, maybe a S2000

Felix Wankel

We can't compare the RENESIS till we get an actual power figure instead of speculation. Has Mazda released what it will actually do yet, or what they claim it will do? I haven't been paying much attention to it lately.

It seems that you have not read thru the whole site huh? Check out my next post extracted from monito.com.
You will also see a 6 port injection 12A engine. here is the whole link for all of you rotary engine fans...

Also from monito.com... You should read the whole site before you say something.. Check this out about half way down. The engines are sorted by date yes we do have two of those engines...

As far as the rotor/e-shaft assembly and high RPM use I understand that for anything over 7,500RPM you need to use special stationary gears and have them pinned to the housings more securely than the way they come stock. These mods are supposed to allw for a 10,500 RPM redline. At those speeds I also understand engine builders use carbon apex seals.
