Thats from the same thread, you say we are too dumb to figure out rotary engines but you don't even know how to read, in a thread you started no less, dumbass.

lol, thanks for bringing up a completely irrelevant thread from 2004. I looked it up and had a laugh, I guess almost everyone goes through that ricer phase when they are 16-17.

Just keep telling yourself that, if it makes you feel better. Truth is you have no idea what you are talking about and just pulling "facts" out of your ***.

Go ahead and read the forum rules at the top of this section...this isn't the place for you to bash v8 because you idolize rotary engines, you are simply being a troll and no one wants to listen to your retarded-ness, so again GTFO!

I didn't realize what section i was in when i made my first post. So sorry about that.

However, i will agree, that this arguement could go on forever, so i will end it here.

I guess from now on i will shut up about anything I say, as you can't get any reliable information from anyone these days I guess, I mean, I though technical information sections were for technical information, not sarcasm.

You all make good arguements, however until i have my own proof, this will obviously be a never ending battle.

Well, except for Rosey, Rosey appears to just be some retard, hanging out in this forum, but otherwise yes, you all are pretty intelligent.

Bleh.

I'd like to voice my opinion on this...

The LSX series of motors are great motors. Its just fact, and to debate that is idiocy. However....any motor, whether V-8, inline 4, rotary whatever....is gonna have issues when you mod them, especially if you tune them incorrectly. Everyone says the rotary is unreliable....personally with my car, I've never had a single rotary related problem with it and I daily drive it...but its not boosted so I can't speak for that. Not to mention when cars come from the factory, their meant to be reliable....you can't sell an unreliable car...its only after you start modding the car that it starts to become more reliable. It seems that rotary motors seem to be more sensitive to tuning then piston motors from what ive seen as well, and they require a bit more attention.

Personally...I like the rotary motor....but i'm not gonna be an ignorant *** and start saying things like "the rotary motor is god and no motor is better in the RX-7 then the rotary despite what your facts may say" ya know what i mean? Also, you can tune any motor to beat any motor. Rotary vs v8....I4 vs v8. I4 vs rotary...whatever...its all in the tuning and the money and time put into it. You cant really say ones better then the other....thats all opinion. You can use numbers to justify your reasons, but not all rotary motors are the same just like not all v8s are the same.

The LSx series of motors arent bullet proof...you can blow them up just like you can blow up a rotary. How reliable your car is depends on how you mod/tune it right? Many rotarys have tons of power and are relatively reliable, especially the race motors and what not...but their built for that and have tons of money into them. I mean if the rotary was as bad as many people say it is....they wouldnt be reliable race motors.

Sure the rotary is race proven...but so are v8s, 4 cylinders etc so saying the rotary is race proven as a defense for the motor is kinda stupid.

Personally...i like the idea of an ls swap. I would do it, but I would want to have another RX-7 to keep the rotary in ya know? The rotary does make the RX-7 unique and its what makes an RX-7 an RX-7...among other things....

And when it comes to swaps....you can fit any motor in any car....as long as you want to put in the time and money required. ****...ive seen an Ls1 in a hatchback civic! That was cool! but anyway...their are tons of motors to choose from when considering a swap...and as the LSx swap becomes more popular, i would probably become less inclined to do it....just because i like the idea of unique swaps....like, swaps you dont see every day.

Anyway...those are my opinions...i dont know if I transfered them to "paper" well enough to convey what exactly i was thinking...but i tried and i think most of you will understand what im trying to say.

Yep, I understand what you are saying.

I think the biggest thing I don't understand, is if someone doesnt like the motor that's in the car, and they swap it out, and say the original one is trash, that's like a smack in the face to everyone who has one, especially the handful of intelligent people who build their cars right and dont have problems.

If more people just said, I simply just don't like the rotary, that's why I swapped it, then that would cause less stress. Because that's exactly what i think, especially with someone who's sig says "Im not anti-rotary, im anti-idiot."

That's why I secretly fantasize about buy old collectors chevy vehicles, swapping rotaries into them, and melting down the old engine/trans to make furniture and engine mounts with.

My vote goes for the 13b-rew, better engine than the 13b-t, nevertheless, stay rotor bro!

Just let your drifting friends, that defined autoworks drift car is a s14, with a 13b in it!

Yes, please prove my point some more.(about you being an idiot) Let me explain(since its too hard for you to grasp) what my signature means. Here we go:


I have ABSOLUTELY NO PROBLEM WITH ANYONE who owned a rotary car, in fact I think they are cool little engines and when done correctly they are bad ***(like that 4 rotor RX7 on youtube).

I have a problem with ******* IDIOTS who blindly talk **** about swaps they know nothing about,(thats where you fit in) and continue to put down the people doing them....like when the ******* on page one said he'd spit in the guys face if he swapped an LS1 on there.

It'd be funny if the US ever decided to enforce the no engine swap rule......the 2nd gen for sale section would be flooded with so many NA's for sale.

TII's and FD's would rise in price though.

why would they rise? 90% of them would have to get scrapped.

So is what you are saying, is that because NA rotaries with a bridgeport can make over 200HP/l with almost no internal modifications, I should be on a honda tech forum? HAH, I hate Hondas, that's hilarious. Everyone who knows me knows I cant stand Honda's, it makes me angry to even sit in one.

Whatever, I tried to go out on a good note but you called me a ******* moron, so **** you. I'll get back to building my T2 engine and making reliable turbo 300HP/L engine that gets 20+ MPG. Let me know when you can make a reliable stock internal 1500HP LS1.

I can't believe I'm posting but...

Anyone who does an SR20 swap into one of these cars is wasting a lot of time and money. It's doing everything people hate about the LSx swap, and none of the advantages. Just check out how much an SR20DET weighs...

But your right, Sr20's are pretty lame motors. No torque, redline at 5400 rpms or less weighs more than a boat anchor. actually i think that is the only thing a sr motor is good for; anchoring boats to the harbor

I am far more interested in the hp per lb. comparison of a powerplant. Hp per liter really doesn't mean a whole lot to me. A stock 346 ls1 weighs essentially the same as one that displaces 440+ ci, depending on specific parts used of course. You will not win many internet hp/liter wars with a pushrod v8, but it's hard to beat the performance for it's physical size and weight.

It would be nice to see an all-aluminum 13B engine compared to the aluminum LS1 in terms of HP per lb. Well mostly aluminum, rotors and seals would probably have to remain what they are.

Too bad we don't have any rich volunteers.

hp/l is a useless argument that honda fanboys(and you...) use to try to make your tiny engines seem more impressive. Hp/weight or hp/physical size might hold up in an argument.

Yawn. Everyone is building a 700+hp t2 engine. Wake me up when you actually accomplish something. I'll be out driving my ls1 powered car in the mean time.

Hell throw in things like HP per mile per gallon as well, the LS is still hard to beat, especially when you start talking higher hp numbers. Then add in reliability.

There is a reason the SBC has been (practically) swapped into everything.

LS1's are very good for their size, power and cost.

If cost wasn't a factor, we'd see a lot more V12's being swapped into everything.

Still, I would love to swap the V8 from the Ascari A10 into an FD........that's 8 cyl full of win right there.

you know, a badass once told me(this guy is my goto guy when it comes down to anything Rx7 or Lsx) that the Ls series motors are awesome. especially for the price. if anyone else were to make this engine, especially the higher end cars like mercedes and BMW and who the **** ever, this engine would cost SOOOOOO much more. but because chevy can mass produce it for a very low cost, a lot of ignorant people out there discard it as another old chevy v8 with 1955 design.

Again, imagine how much this engine would cost if mercedes made it identically...

I love the rotary engines but they do require more maintenance than piston engines, which is a turn off to most people.

In the end don't ask which is better, read up on the subject. Educate yourself and decide for yourself what fits your needs, and what will make YOU happy. I want a 13bt doesn't mean it's right for everyone. At the end of the day it's your car, so who cares what other people think. As Dave Coleman once said "Other people suck, who cares what they think". Asking for opinions only puts people on edge, defense, and takes away the reason why we are here whether that reason is a SA, an FB, FC or FD.

go with what you feel and like...and educate yourself cause when it's all said and done...it's your car good luck...

Just the thread I was looking for...

Since the LS1 mentioned specifically in the title, the LS2...LS9 whatever should not be applicable, unless you wanna make a good argument why it should be?

I question how CHEAP the LS1 can be built for?
Does it put down 400hp at the wheels in stock form?

What needs to be done to make it put down 400 at the wheels?
Remember, 400 at the wheels comes out to 460bhp - 470bhp at the crank.
How much do these parts come out to?

What about 500 at the wheels?
How much does this cost?

Lots of people claim it's cheap, but I don't know how they get their numbers from...
Set of LS1 heads - $1,000
Cams, lifters, pushrods, etc. - $1,000
This **** ain't cheap.

Granted, at the 500hp level, building a 2 rotor isn't easy either.

The LS1 does have a big advantage when we're talking stock-for-stock engines.
The LS1 does have an advantage in torque.
But, when we're talking about big power (over 400hp), it isn't that cheap!

Don't even bring in NOS...
You can NOS anything.
It's not permanent.
