If you want to buy an RX7 just to put a V8, it'd probably be more worth your time ot buy a car with an SBC V8 in it.

My friend rebuild two saab T3s, welded up some manifolds and stuck low compression heads on his 350 chevy small block, which resides inside a Jaguar XJ12. He's in the process of looking for an XJ-S and he's chucking the V8 in favor of the origional V12.

I don't see anybody talking about aviation here. Your point is...?

How long has the 911 been around? Porsche has had more than enough time to iron everything out. The RX7 wasn't designed with this in consideration.

How origional. If I had the money I'd put an S2000 engine in a 240.

I would be dumb and crazy enough to buy a priceless concours-quality '68 Mustang, a Mach1, Yenko Camaro, or a '69 Z28, or a convertible Hemi with matching engine and chassis numbers.
I would be dumb and crazy enough to sell the engine to someone building a Cobra kit car or part the engine out and sell the block for scrap.
I would be dumb and crazy enough to install a very ported, very built 20B with a very big turbo.

They'll have the last laugh of course. I'll just pretend I don't know English.

LMMFAO I was wondering why in the hell I got 4 forum mailers with the same name on them...hahaha

Really your Viper handles better?

This doesn't take into account the chassis flex or insane amount of brake fade that a Viper experiences as well.

And for the $35-45k you'll spend on a good condition early model Vper you can easily make the RX7 beat it in a straight line, blow it away in the corners and braking with money left over incase you break something.

But in the end you still have an RX-7. The end result of this "Viper killer" is an engine half-life of an hour and gets 15 gallons to the mile.

Miles per Gallon 13/22

How is this any different from the Viper in MPG?

As far as reliability I don't have to run 2 bars of boost or push huge RPMs to outperform a Viper. You should realistically see 15-50k miles out of the RX-7 motor depending on how hard you drive it....about the same as the Viper motor except a rebuild/reman will cost you about half as much on the RX-7 motor.

Vipers are a joke, a LS1 RX-7 or a Vette is actually a real sportscar.

well my uncle is installing a lt1 in his wifes xj12, after putting one in his daily driver. that v12 is nothing special and after trying to work on one, you might do the same. the only thing you lose with that swap is the nice v12 sound imo.

the whole point of RX-7s is to get away from the piston engine concepts, and try new things. I think putting anything other then a rotary engine in a RX-x is wrong, find some other car to whore out, but for the love of God, leave RX (Rotary Experimental) cars rotary

I personally love the idea of a rx7 v8 because the rotary engine design was and should have remained a water pump .The styling of the rx7 is nice but the power plant under the hood is all wrong! .The v8 engine can be mounted in the same place as the rotary. The small block v8 only ways 75-125 lbs more depending on engine components.The 50/50 weight can be restored by relocating the battery to the back and changing to a fiberglass or carbonfiber hood.. I put a 89 5.0 leter engine in my 1990 gxl and have never been happier with the bottom end torque. As for the handling in the corners it's still just as good as but the gas pedal is crispy and responsive. No regrets not one..

I have both a V8 powered RX7 And a rotary RX7
The one with the V8 had a blown engine thats how it ended up with a V8.

here is something I want to know.
Why does it matter So much what "OTHER"
poeple do with their cars?

I say if you want to keep it rotary then more power to you.
I say if you want to make it a V8 RX7 then more power to you.

Is there any real point in bitching and whineing about it to one another?
Do you REALLY think you are going to change one or the others mind about what they are doing with their OWN car?

If you answered yes to either of these two questions then you should wait for a really windy day, stand outside faceing the oncomeing wind, and take a piss as hard as you can, the end result will be the same.....;)

V8 rx7
 

I have a 88 convert with a 383 and a T5 trans. A HELL of a better driver and easy high 12's low 13's everyday driver. I love it 100 times better then the slow ass factory set up. It is easier to work on and part are cheaper. The only down fall so far is the gas mileage. You have to play to pay. For sale is my 77 porsche 911 with.. yes a chevy 350 in the rear.

I like the thought of installing a LS1 in the FD, it makes a great car even better. I wouldnt do that conversion to a stock original FD like mine that cost 20K. I would perfer to get a FD beater under 5K + 8K for conversion , if you are going to spend over 20K might as well buy a used Vett.

it was as said by tough guy out of my ass i didnt feel like getting into fractions at that moment

I love my v8 rx7!! Runs 11.5s with a pretty mild 350. It turns alot of heads when people expect to hear a rotary motor

Yea, people are not used to seeing something like that. It's just not 'ordinary' and the looks you get alone are worth the effort. Not to mention how much faster it is. I don't have a problem with rotaries - my rotary had a problem with me :p:

WOW thank you!!!!!!!!!! This is sooo true. We will never make someone on the other side of the V8 fence come over unless they had some idea of doing it after.... my engine goes out.... I get enough money... whatever....and then they support the V8-7 anyway so it doesn't matter

You little rotary dildos...
 

For all of you little piss ant rotards who doubt the complete superiority of the American pushrod v-8 over the rotary let me enlighten you from actual experience.

If you take away the following facts;

* The LS1 powered FD is faster than the rotary FD

* It sounds better

* That because of it's broad torque curve and instant throttle response it handles better

* That it is way more fun to drive

* That it gets better gas mpgs

* That it will actually pass an emission test


And just concentrate on reliability. And the fact that I've been driving the hell out of my LS1 powered FD for a year and a half without so much as doing one repair or any maint besides oil changes. The LS1 wins hands down.

Just the comfort of knowing that my engine isn't going to blow up made it all worth it. All that extra performance, handling and mpgs that I got on top of it is just gravy.

Suckers.

Alum. V-8 is the final frontier. I think it is a good ideal because if you are looking at 600hp plus V-8 is the only answer. Sure BT and REW can make big power, but for people like me who likes to beat on it track event after track event I don't think a turbo rotary will take the beating and be user friendly on road course like a 500-600hp NA motor. 20B...... I don't think for the effort it is worth it. I don't know but 20b just is not that fast for all the money I seen or hear people spend. Drove a FC 20B and you think the extra weight in front would not be that bad but it was bad. If weight dist. can be worked out V-8 is good and it looks like the chassis can actually hang with it compared to other cars. Drove my friends supercharged LT-1 240z and the drivability was great. I am sure there are some high power 13B that can keep up but the response and control of the power from a super charged or na V-8 is hard to beat.

Well if you want a v8 in your rx, please remove the RX badge. Thats all I ask. I know that the v8 swap is a hell of alot cheaper and has more power, so it is understanable that people would want to do that swap, more bang for the buck, but it is no longer a rotary experiment, so remove the badge. That way you want look like some rice kid with a Nismo sticker on his stock Sentra.

yes it is a rotary experiment that went wrong, why can't i still call it an experiment ?

I'd like you to show me 2 things:
1)Legitimate Mazda publication explaining the "RX" in "RX7"
2)A badge of any sort on my car

Worry about your own car and not what kind of stickers or badges are on mine, ok?

This is just stupid, I've never seen so many people bitch and whine.

So what if they want a more reliable car. I don't like domestic cars but I know that Chevy has always made a good longblock and now this one is aluminum it's even better.

Remove the badge? The car is still an RX-7 no matter what, even though there are still tons of people that think mine a Vette!

I don't go and bitch at you cause I don't like the boost gauge you installed!

LOL, I'll put a GTR badge on my RX-7 if I damn well please... :D

That's like saying that the old 32 Ford guys should take the Ford badges off if they have Chevy 350 under the hood.

I can appreciate that the purists don't like it, oh well, see me care... :)

Hi, I'm new to the forum and the 'RX-7 scene'. Recently bought an '87 RX-7 with what I am assuming is a blown apex and a blown side seal (from the FAQ thread.) I have been trying to decide which I should do: Rebuild the 12A or swap in a 305 or 350 (I'm partial to Chevy engines.)

I would prefer no one tells me which one I should do, I would only like 'advice'. And please only speak from personal experience of actually having DRIVEN one. I hate it when people post false tech, or "someone told me that..." (Flaming is usually the only outcome in these situations.)

After reading all 9 pages of this thread, what I need to know is this: How well will an RX-7 with a V8 ride as a daily driver? From what I've gathered from this thread, the handling isn't totally destroyed. However, I don't plan on doing autocross, mainly drag. Gas mileage is not a problem, because, as has been said before, you have to pay to play.

P.S. Please post maturely.
