Pretty impressive. If some of you don't know the Ls1 engine is from a Vette

the rotary IS a real engine...

[Nemisis8u]

the rotary IS a real engine...

.....umm sure. I've heard nothing but bad comments about the rotary. It still is a pretty cool car.

[initiala4]

Rotary = light engine. I wonder why did he stuff a Chevy V8 inside it....whats wrong with the engine that came with the car? :roll:

[AlienDB7]

Why didn't he use the LS6 instead?

[stracing]

another dickhead who likes defeating the purposes of an RX7 i presume? just like lowering an off roader
anyways he could extract the same amount of power from the rotary compared to the V8

[tkach]

stracing think about it. a rotary engine has to rev up high to make any power. also they are expensive to make power with. so a v8 conversion isnt exaclty a stupid thing. i doubt youve been around alot of real car people who accualy work on cars but if you have the phrase "theirs no replacment for displacment" may have come up and its true. dont get me wrong i can make a rotary make 500 hp i can also make a v8 do it for less then half the price with alot more tourque and a better powerband so i dont have to rev the motor way up to see any power. its like vtec motors. no power below vtech nothing. now the little rotary engines are light and small so they go along nicly with mazda's 50/50 theory. and if i wanted a rx-7 purely to handel yes a v-8 would be a bad upgrade. but if i want to make it very fast in a strait line well then bring on the new motor mounts and the 350.

[tkach]

no the v-8 unlike a rotary is not a piece of crap. you can also rebuild a v-8. also the lack of sophictication makes it more reilble less can go wrong. please dont hit me with this jap motors are high tech and blah blah horseshit. first of the rotary is a german idea. thats why it was called the wankle after the german who invetned it. 2nd they are crap. i got my mazda rotary engine mechianic certifaction in college a couple years back. not only was the class crap but the motor two. u cant rebuild a rotary and make it work right. and varible valve timming wasnt invted by honda seeing as i am on a rampage agasint stupid techno savey people who think high tech= faster all it means is more problems. im not attacking anybody here dont take me wrong. im not trying to be mean. just trying to make others think. whitep this isnt some hateful thing agaisnt you. i dont know what you ment, but id rather say it all now other then in 20 little posts like a post whore. but i do like the rx7 they are fun but i like sick low end power, and sadly the rx7 can never provide me with that. unless its got a v8 under the hood. btw anyone tested out a rx8? i wanna hear real peoples oppions on them. in la they are on a back order i know a girl who bought one hers wont be here for another 3 months. so test drives arent avaible atm.

Hey whats the codec I need for that video? My computer here at work tried to download some codec but came back with a codec error.

:(

I want to see a japanise car with a brutt of an american motor in it.

:mrgreen:

[Jabba]

A very good program to identify which codec is used in a video is G-Spot....

Find out all about it and download it here....

Cool. Absoutly love the name of the app.

[stracing]

tkach...your second last sentence basically summed up why its stupid.
yes i have been around ppl who muck around with cars.
my point which i made VERY(to the power of infinity) clearly defeated the purpose of an rx7 which seemed to go in one's ear and out the other

and sometimes price isn't main concern with ppl

[Jabba]

Cool. Absoutly love the name of the app.

Also for problems with WMV files I have found downloading the very latest version of media player from microsoft gets most things playing...

[AlienDB7]

According to microsoft, you need the new WMP (7 or newer) to play wmv's encoded with vbr wmv9. Old WMP6.4 (my prefer player) works with cbr wmv9 though.

[fishfreek]

Im using media player 8.00.00.4487 here at work.

[Nemisis8u]

I have wmp 9 so mine worked no problem. As far as the comments go how can you "stracing" tell that that V8 defeats the purpose of the car? I don't think that you have any data that will tell us the weight of the engines. Do you? So calling the person who did that a dickhead is not very appropriate. Additionally I doubt that you can extract that horsepower safely out of that engine. Surely it will run, but for how long?

[stracing]

so you agree that a V8 is lighter than a rotary? maybe a small block it will be just the same. was it a small block he put in it? i haven't dl the vid yet
i'm comparing a V8 seen in a commodore when parked next to a RX-7 and you'll see how much space it takes up. with the materials used you know it'll weigh quite a bit.
also the acronym RX means Rotary eXperimental does it not? so whats the point of calling RX7 why not V8X-7?

mazda designed a lightweight car with a rotary that goes fast around a circuit. then this person goes and puts in a V8. now he would have to tune the suspension to compensate just to go just as fast around corners as he did before. so basically its not lightweight and its not a rotary so hasn't he defeated mazda's main aims? it would be just as stupid if it was reversed, putting a rotary into a commodore. it'll never produce enough torque to pull that lardy arse. actually mazda has made that mistake before with their toadpacer something or rather.

[novass]

i dont know much about rotaries, but from what ive heard they are a pain in the ass. one of my roomates works for a Subaru/Mazda dealership in the service department and he hates the things because they are so unreliable.

also im not sure how much a rotary weighs, but an LS1 is all aluminum so it may not weigh as much as one would think

[AlienDB7]

The engine in the RX8 actually weights about same as the 1.6L ecotec (100kg) from lotus.

"Further development of the rotor is possible of course. Better
casting techniques are used by Mazda to reduce the weight of the
rotor in the RX8 engine. The RX8 engine is rated at 250 HP at
8500 RPM. Not bad for a 200 pound engine twelve inches wide,
fourteen inches high and seventeen inches long. This is an
exceptional power to weight ratio and power to size ratio that
exceeds any piston aircraft engine despite the use of low cost
cast iron rotors and end housings."

In contrast, the LS1 weights 390lbs

rotary motors are great motors, you just have to be familiar with them. the rotary got a bad reputation because of the thrid generation twin turbo RX-7. seems alot of owners couldnt follow instructions and feed them high octane only, hence causing detonation, hence causing bad motor. i have tons of experience with rotary powered cars, some well over the 150k mile mark and running strong. the people who bash the motor are usually the people who dont know anything about them.

RX7 With A REAL Engine ?

So the rotary Jesus Padilla dominated with in the NHRA All motor class last year isn't a REAL Engine?

[hemi_fan]

For those of you saying that the SB 350 is the same weight as the wenkel, ur wrong, The wenkel is lighter than many of the 4cyl engines. They also make extremely good horsepower compared to their size and weight. The main reason why they are not widely used is because their design makes it very difficult to repair them. They have rubber seals on each point of the triangle in the housing (if you dont know how they work, i'll post pics, just tell me). When these points wear out, you suffer massive power loss and possible failure. In order to replace these, you litterally need to rip the entire engine appart just to get at them. This is why many people do engine swaps in them. They really aren't "High-Tech", just a different design compared to a regular combustion engine. Id still much rather have a V8, just because I love the sound and feel, but these wenkel engines are extremely good, so dont be cutting them up either.

[SilverPhoenix]

The V8 is just not as sophisticated as the rotary...

or as complex so therefore more reliable, and rotaries aren't exactly lighter, the LS1 weighed in 6lbs lighter than the S2k's engine.

[oic0]

The whole point of a rotary is that its a much better design than the piston engine. They have bad reliability because they havent been refined. A piston motor is an unreliable piece of crap too, theres just trillions of dollars of research and refinement in them as theyve been around so long and are so popular. Did you know GM almost put a 4 rotor 450hp motor in the corvette at one time? they even made a concept car of it with a running engine. They changed their mind though because they didnt want to alienate customers or something.

[JeromeBaker]

Wow that is a cool video. The mechanical coolness alone gets this video two thumbs up.

But, did anyone else notice the fluids leaking from underneath the car when he was reving the engine in the garage/driveway?

Are you kidding me? The 13b has 3 moving parts, no camshafts, pulleys, valves pistons, rods etc. It just has a rotor that moves in an oval.

The only reliability problems with the rotary is the extreme amounts of heat they generate from the sequential turbos. People improperly tuning them add to their detonation problems.

or as complex so therefore more reliable, and rotaries aren't exactly lighter, the LS1 weighed in 6lbs lighter than the S2k's engine.

Do you have any idea what you're talking about? The S2k has a 2.0L 4 cylinder motor.
