2ND generation rx-7 --- v-8 conversion kit.

they move the battery to the back and set the engine further back so the weight distribution is maintained. the car does get heavier but that is offset by the fact that the v8 has more torque. thats the reason for the swap.

swapping a 30 lb battery to the back of the car and setting a 400lb cast-iron v-8 block "back" in the car does not maintain the 50/50.. . if you are going to set the engine back, what about knocking back the firewall ??? ... the 13b as it sits weighs a whole what 200lbs (IF THAT) ? and revvs to 7000 with ease... very smoothly i might add.

why you would want to destroy a perfect fc is beyond me... only reason one would abandon the rotary is because they don't understand what they truly have.

hell a ported 20b would run circles around any v-8 conversion fc or fd, not to mention out handle it.

i may be new to the rotary scene, but i take the time to cover all aspects of the market.... i'm not going to shun something simply because "it ain't got no pistons"... typical quote of a v-8 owner.

give me a bridge ported 20b, a decent fc or fd, and i'll run circles around your v-8. this thread should die... there's a reason the rex'es came with a rotary ... it was meant to be different, not like every other car out there.

just my $.02 and all in good fun guys...

let me tell you something. the 13b does not weigh 200lbs, at least not a turbo one. Trust me, because it took 3 people to lift my turbo motor into my garage. Maybe its 200 without anything on it, its more like 260-270 lbs.

the fc engine bay has alot of space in it, so moving the v8 further back isnt as impossible as it seems. the weight distribution is maintained. if somebody knows what theyre doing they will do it correctly.

but i completely agree with you about the rotary engine in teh rx7 and why it should not be replaced. hell. i'm not getting a v8, i got a turbo 13b, were no enemies. btw the 20b would throw off the weight balance of the car also if not for other modifications.
the v8 conversion is only cheaper because its easier to find some dumb chevy 350 than it is a japan only 20b.

lol... i've got a 13b in my garage, in pieces, DON'T MAKE ME WEIGH EACH PIECE !!!! LMFAO... kidding.

i daily drive a piston-powered car, and its reliable, and runs fine.

i have a rotary toy, and there's no way to describe the powerband, you can certainly attest to that... why anyone would want to trade that giant smooth powerband for a rattly v-8 ... i guess i just don't know.


pound for pound, i'd put a tweaked turbo fc against any v-8.... but that's just me

I dd my FC...

dd your fc ? sorry i'm not up on all the recent terminology

daily drive... lol man i'm retarted.

its ok.

well since you daily drive your fc, what kind of mileage do you see out of it ... (curious, since yours is a turbo)... i get no better than 20 no matter what i do.

my car is non turbo, and i am swapping in a turbo engine in a few weeks.

i never really checked the mileage, but i guess mine is around 18-20 depending on how i drive

stock ecu runs rich which is part of the reason why its so bad.

when i swap the motor, i'll have a apex safc and see how that affects anything.

why would you take the BEST part out of the car and replace it with a PISTON ENGINE :S

hey ... in addition to the "richness" of the ecu ... yeah, that's true...

buut. i'm pretty sure the side seals are gone in my 7 ... if you park it cold or hot, and re-start it, and get into it leaving, it smokes like a cropduster until it fully warms back up, which i am assuming is oil leaking past the seals, and then burning off when you re-start it. which is no big deal, but...

i took my 7 thru emissions here in ohio... with no air pump, shitty plugs, and the faulty side seals... passed emissions with flying colors, i was sure it was going to fail, which blew my mind...

burning oil and richness from hell .. and it runs great... lol

Lets just put all this bickering behind us and marvel at the fact that a 1.3L engine can do such wonderful things. lol

Fuck, i need to move to ohio.

why, to get around emissions where ur from ? (what state are you from?) e-check is hell on older piston engines and diesels, but they're doing away with it after this year. its only a caunty based thing right now, but they're talking about making something state-wide later on

Lets just put all this bickering behind us and marvel at the fact that a 1.3L engine can do such wonderful things. lol

if you really think about it, yeah mazda calls it a 1.3L, but ... in all reality its really 3x that size, and has 3 power pulses per revolution. its similar to a 2-stroke in setup (porting, oil injection) and a 13b has the equivelant setup to a v-6, because each side of each rotor is doing a different thing (compression, intake, ignition, exhaust) ...

this explains terrible fuel mileage, and power that's equivelant to a 3.9L in power potential.

lol, you dont know shit about this stuff, go do ur homework before trying to put up arguments.

and since you've bring up that argument swapping a 30 lb battery to the back of the car and setting a 400lb cast-iron v-8 block "back" in the car does not maintain the 50/50.. . if you are going to set the engine back, what about knocking back the firewall ??? ... the 13b as it sits weighs a whole what 200lbs (IF THAT) ? and revvs to 7000 with ease... very smoothly i might add.most of today's recent v8 can be found with an aluminium block, and whats nice about the gm engines is the T56 tranny.

im not saying i like those v8 swaps, but dont spit on em, they're as heavy as a 13b is and that has been proven. the battery swap is to give more space under the hood, since the only real difference is the height of the engine. but since none of us here compete in any big class world racing or rally shit, its not realy a valuable argument since u wouldnt even notice the changes

oh i forgot ... pistons are so cool. asshole

just dont piss on em, thats an easy thing to do.
let those pricks play their game alone, dont become a prick by playing too.

alright ... sorry for my foul mouth and etc. this thread needs to die

having a V-8 in an RX-7 would make it front heavy, meaning you would need new steering components, and maybe if you were to build it with lots of power drifting around every corner could be the best thing in the world. you could drift like a pro just trying it for the first time.

I guess you could look at it like that... But in my own eyes I just couldn't justify a v-8 in an rx7. If you want a v-8 in a car go buy a mustang or a camaro. They're just as capable in their own respect.

I've seen 5.0L mustangs that would eat an rx7 alive, but I've seen rx7's that outran the large v-engines like they were sitting still.

all in good fun ... read the signature

no.

havent we discussed this already? read the last 2 pages to see why its not true. the ls1 weighs slightly more than a turbo 13b.

ok, i'll spell it out...

if you put a v-8 into an rx7, you are ignorant because you are simply giving up on the potential a rotary has... or the unwillingness to try something that's part of a new territory to someone who only knows "it ain't got no pistons"

No, it doesn't, proven earlier in the thread.

So you're essentially saying that putting a V8 in an RX7 makes it the same as a camaro, (or, worse). So that, outside teh engines, there's nothing special about the RX7 that you can't get in a Mustang or Camaro? You really hate the RX7 that much to think that the engine is the only part of the car that is important?

That attitude completely ignores the fact that the FC is lighter, looks better, is better built, has better brakes, looks better, has better ergonomics, is smaller, looks better, has a better interior, better suspension, looks better, etc... the FC is numerous, cheap, easy to get, and unlike a lot of swaps, is dirt easy to do as the engine compartment accepts the V8 as though it was designed to be there. And the chassis carries the engine in such a way that it simply doesn't change the balance that the original car had, due to how far back it sits.

The car is far more than the engine, and we can be a enthusiast of the rest of the car, and even still like the engine, and still want to swap the V8 in. And it's been proven time and again that the conversion doesn't "f*ck up a unique car" but it DOES change it into a torquey, fun car with a different character than the stocker. Not necessarily better or worse, just different. In fact, most V8 swaps aren't done to cars that are in good running condition (though as those get cheaper, more conversions to running cars will happen), and are instead done, as my car was, to dead cars that even you rotary purists won't pay any money for.

I love rotaries. I'd love to see a TT 20B in a '66 Mustang fastback (a car that weighs about the same as a stock FC TII, BTW). A rotary porsche 914 is cool. I'd put a 13BT in my Fiat 124. I've put one in an MG before, and have drooled over Gibson's 400+ RWHP turbo 13B in a Triumph Spitfire. But somehow, because I support V8 RX7s, I'm a rotary hating redneck to people like you, and I just don't get it. This is supposed to be a fun hobby. It'll be the most fun if people simply knew what they were talking about, and didn't give others shit for building cars the way they want.

The RX7 is a light, balanced chassis regardless of engine. It's a GREAT looking car regardless of engine. It's a well built car regardless of engine. How come ALL you can see in your OWN CAR is the effin' engine?????? Apparently you think the rest of the car is a POS that only exists to give the rotary something to move around.

hey chris..


Why? Is it too hard for you to be able to actually use yor brain?

Why can't we have an intelligent conversation without people like you being little bitches about it?

JUST MY OPINION, NOT LOOKING TO START A FIGHT

I had an R100, RX2, 2 RX3s, 2 first gen RX7s, then the FC. I also had a 12A powered MG Midget, crewed for an SCCA rally RX2, and an IMSA RS RX3 road racer and the same team's Formula Libre 13B powered formula car. All my rotaries (except the R100) were slalom racers and street cars, with my '73 RX3 with the heavily ported later 12A single dizzy engine being my favorite (wish I had another one). Fricking fast little car (ran 13s back in '84) and a lot of fun to race and waste the average musclecar with back then (most street musclecars back then were like jacked up Novas and the like that weren't as fast as they could be. 13s on the street was enough to win a LOT of the time in stoplight confrontations...).

http://mywebpages.comcast.net/cvetters3/RX3.jpg

One of my first gen RX7s had an RX4 13B that was heavily ported. the car was beat up , but that engine was nuts in there. ;)

My FC was bought to go autocross instead of teh Porsche 944 I was looking for at the time, and after I had Greg Fordahl set up the suspension, it was a champion autocrosser. But when it died in '93, and I had the choice of rebuilding it to stock specs for big bucks, or trying to make it fast for even bigger bucks (and unreliable), I got to looking at the empty engine compartment and realized that the small block Ford would fit in there perfectly. hell, there was more room in there than in most Mustangs...

http://speed.supercars.net/pitlane/pics/484414b.jpg

I had the car for 5 years in V8 form, finally selling it in '98 to pay back taxes. It was completely reliable and an excellent autocrosser and street driver. Yes, it was different than it had been as a rotary car. That was the point. I wanted to build a unique hot rod, similar to a modern version of the Shelby Cobra Daytona Coupe.

I still love rotaries, and would love to build a rotary powered hybrid car. If I hadn't gotten my '63 Comet convertible project started, I'd love to put a turbo 13B into my Fiat 124. Wouldn't this car be cool with a Turbo II engine in it??

http://mywebpages.comcast.net/cvetters3/fiat_spider.htm

Does that look like a car an ignorant redneck would build?

This is a HOBBY. It's supposed to be FUN. It's not supposed to be about worshipping religious idols and attacking people who you label as heretics! Cars don't HAVE souls. Cars are mechanical objects built by people.

I built mine for fun after my autocrossing FC died. And it was a faster, better handling autocross car after the conversion.

http://mywebpages.comcast.net/cvetters3/rex1.MPG

But that wasn't why I built it. I built it because that's the way I wanted it at that time. it was fun, and when I built it in '93, it was the cheaper route. As well as being more unique. I HAD Mustangs and a Trans Am before. I didn't want another one. I wanted to see what would happen if I took the nearly perfect FC chassis that I loved the looks of and already had, and ran a cheap, light, high torque engine in it. The result was much more than the sum of it's parts. Much like the result when I put a 12A into an MG. that's what the hobby is all about. And here, I run into closed minded idiots who would rather insult me and the car than just learn from it, basically saying, "I don't care what the facts are, I want to be closed minded and insulting" as though thats a valuable goal for your life.

ok, i'll spell it out...

JUST MY OPINION, NOT LOOKING TO START A FIGHT

BTW, opinion can be wrong. Here's an analogy (you do know what that is, don't you?): Let's say someone came on here and started a thread that said RX7s will never be fast, and rotaries will always be slow, because he once had an N/A RX7 that ran 16.5 second quarter miles, and was beaten by a stock Civic Si.

How do you think that would go over?

Do you think people here would not only tell him he's wrong and an idiot, but back it up with proof that he's wrong?

And if he came back and argued with them the it was just his "opinion" and he should be allowed to state it without being insulted, do you think he would be let alone? You think everyone would go, "oh, it's ok now, because it's just his opinion."

No, being insulting and factually wrong can't be simply ignored because you say it's "your opinion."

Always amazes me that people like you want to be able to state your opinion without anyone being able to state theirs in return.

i can use my brain chris, i just dont know why you keep up answering the thread, its been 10 pages now, i think everything has been said and done, and theres no use to repeat something thats been said 2 post earlier.

Because no matter how many times things have been proven, little kids with no experience keep saying the same retarded things.

This is a hobby. It's supposed to be fun, and not about attacking people who modify or otherwise have fun with their cars as though someobeody's religion is being upset by said modifications.

It's sad that there are musclecar guys out there insulting small engine cars out of ignorance, and it's sad that there are small engine fans attacking hot rodders out of similar ignorance. I try to educate people when I have time by using direct experience garnered over decades, and people like you complain about it. Why? Why do you care if *I* take the time to try to educate people and tell people they need to be more openminded? I'm not telling anyone they have to make theri own cars like mine. I'm only educating them on why their misconceptions are just that.

Tubjub basically directly insulted me by making the statements he did about the conversion in his last few posts. So now I'm attempting to address those insults in an intelligant, and informative manner, and you tell me to shut the fuck up? Why is it so important to you to be that insulting? Up to the point you said that, I didn't even insult HIM, much less YOU. Are you that immature?

the picture is more a gross maner to tell you were all bored of seeing this thread up to the top again and again,

let tubjub think whatever he wants, you cant teach someone how not to be dumb on internet, and by trying to do so, you look like a dumb yourself.

and i think you should stfu, take it as an insult or not, im fucking bored of seing this thread, and im not the only one.

and tubjub, stfu too.

How? How is putting factual information on the internet 9which is what it was designed for), especially factual automotive[ information on an automotive forum, "dumb?" Seriously why would you complain about that?

and i think you should stfu, take it as an insult or not, im fucking bored of seing this thread, and im not the only one.

If you're bored, don't fucking click on it. It's apparent that people still don't have any knowledge of the subject, so teaching them is still just as important to those of us who actually like the hobby, regardless of when the thread was started.

If it isn't important to you, don't participate. But factual automotive knowledge is kind of the purpose of an automotive forum. You have zero influence over whether I post factual information about various cars here. And in fact complaining about it makes you look like a whiney, immature retard that would rather be ignorant than actually know anything. Why is that a valuable goal? I can easily tell you why having automotive knowledge is important on an automotive board. Can you make a relevant case for promoting ignorance and closedmindedness without looking like a fucktard?

Grow up, loser. :loser:

putting factual information is ok, i see nothing wrong with this, i have a problem with repetitive useless thread.

anyway, im off
im rx7less and im bored of this fucking site

chris, pm igor about being a mod, you seem to be just like the looser they hire

damn, i ain't been here in a while...

funny how chris talks to his damn self ... (must have nothing else better to do ?)

oh well who cares... this thread is old ... and i simply don't give a fuck anymore.

and if ur still around, go ahead, start some more shit ... i'm sure we can argue mindlessly about it for another couple weeks.

peace

and where's drftk1d at ? decided to sit this one out eh ?

oh well ... i sold my 7, became a bottomless pit... lol

why was it sold?

well, it got to the point that the side seals were so shot that it used a quart every day or so, you couldn't get "on" it hardly at all without it blowing oil like hell... which fouled the plugs out so bad the car lost a ton of power... and other than cleaning the plugs everyday, i found someone who had the time and money to rebuild it, i had $300 in the car, got $1000 for it... they are priceless to the right person. ran like a dream otherwise but i got bills to pay... ya know ?

i feel that, ya gotta take care of whats important first. any plans to re enter the rotary world later on?

aw hell yeah ... i got plans to find something more exotic

i wanna find a first gen with a 12a ... i know someone local who had one for sale but swapped it out for giant ford v-8 ... just not my style if i want a 7.

i'd like to find any mazda rotary car to be 100% honest...

any ideas ?

if not i may pursue the toyota scene and get a mid 80's RWD corolla

i like the 80s corolla idea. a friend of mine is going to drop the engine from his 2nd gen supra into a celica gts convertible, last year they made them RWD. the engine isn't turbo, but still, it'll be a nice horsepower gain from the 22re... well i think that's the engine that's in the celica... anyway, that'll be a fun project.

lol... i was hoping, and i guess i'm fortunate that i didn't just start a war, considering the toyota has PISTONS and all... lmfao. yeah i know they didn't have the 22re... i think that's a truck motor ? not sure tho. they weren't all that powerful, but they had some crazy handling and impressive drift capabilities. had a friend with an 85 celica supra... cleanest 85 i've seen. i want that motor in a smaller corolla of same year... lol anywho i'll stop be4 i get told to take this to the toyota forums...

well this thread has officially gone off topic, so i'm going to try to get a mod to close it off... it's gone on for way too long.

i've seen 12a's and 13b's in hachis... :)

A friend of mine has a 85 with an 81 12a motor thats been built pretty well. It was a carbed turbo conversion but since blowing the turbo hes just went back to na. Hes got a full build sheet for the car including suspension upgrades. Has nice recaro seats . Was settup for scca. PM if you want more info about it.

Hey Guys, Don't mean to steal this thread but here's a concept you should all try to embrace...

Its kinda hard to judge a vehicle's performance just based on 1/4 mile times. I mean, think about it. An engine with less cylinders can rev up faster than one with more (ie: a 2-cyl bike motor revs up so much faster than a V8) So, when comparing this on short distance runs, of course a small quick spooling rotary will proove challenging to a v8. What the smaller motors have in acceleration, they lack top end. on the highway, a V8 will be able to crumble a small 4-cyl because of all that extra power available. Quick and light is the best way to accelerate. Now I'm also not discrediting the v8 and saying it can't accelerate like a smaller rotary or 4-cyl, it would just have to make up for its acceleration lag via pure brute force. Same for the rotary engine. I'm not saying it can't keep pace or even beat a V8's powerband at speeds over 100mph, its just the characteristics of these different motors make it hard to compare...

so thats the explanation as to why a lancer evolution down in florida rips on vipers, vettes and camaros all day and its a 4 cylinder? btw rotaries are pretty good on top end. (try driving a FD)

to everybodyout there that thinks v-8's are better than rotary's think again. Just of few turbo changes and fuel managment you can easily get 650+hp out of a rotary. Check out this web site they have the kits.

First of all i started reading this topic and had to join. I am on both sides of this arguement most of the time, but have to side with V8. My buddy has a rotary and it is FUN to drive. Shifting at 9000 rpm, quick, just over all fun. But anyone who thinks that a rotary will out run a v8 they are on some sort of drugs. i have a stock chassis car, with 8.5 inch slicks. it is a small block chevy, but it runs 5.20 in the 1/8th mile at 135 mph. The motor cost me bout 6000 to build and is done the right way. if yall ever find a rotary that can keep up yall let me kno and send them to tx. I will show them what a real hot rod can do!

this thread is old as hell dude.

check the post dates before you decide to bump a really old thread
