One of my good friends put a buick grand national motor into a Datsun 240Z (I think thats the model) purchased the motor and tranny for next to nothing (automatic) high kilometers, from there he did a lot of cosomizations, anyways, he did a lot of body work blah blah, didnt work on the motor, put on slicks and ran a 13 second run... Not bad if you think about his costs..
The rx7 v8 is a great idea... But the thing is "WHO can really do it.... "
1st you need an rx7 (Gx/Turbo.. Dont matter what) Personally I would recommend a good conditioned rx7, that way you dont have any other bullshit problems on the way.... 2000/3500 dollars
2nd Collected money for the LTI/Transmission, that will cost you some spare change, and your best bet is to get one that is in good condition ... Simple equation = Good Condition Rx7 + Excellent Motor = LONG LIFE 2000/4000 Dollars
3rd... Having it installed, NOW this is the crazy ******* part, either you know your stuff or you dont, if you dont have friends, or a mechanic that knows how to swap, dont even bother with an rx7 V8 swap, sorry friends this is not simple stuff to do, what I would do is look for someone in my local area, and talk, get to know him/her, and pay them for the installation
Think about that for a momment an rx7 with 320 + hp with a 6 speed tranny, that runs possible mid 12 seconds passes with no MOTOR work, and an insurance cost OF NOTHING.... And the total cost will not be more then 8000 Bucks thats including a good conditioned Rx7
Wow...
The only thing I can say to you all is... This is not amateur **** to do, I showed the article to the same friend who did the GN swap and he said it would be a lengthy project for someone who hasnt done it, but a simple procedure for someone who did
Inexperience = approx 1/2 months of works
Pay/Somone who does = approx 1 week
Ps... I did a swap on a DSM (Diamond Star Motors) Eagle Talon... And we swaped the 1g motor with a JDM motor (1g) cyclone... It took as 4 weeks to complete it (we didnt know what we were doing at first)
We then had another friend do the installation at a store/mechanic, and he took 4 days....... NOW THATS WORTH THE MONEY

The V-8 conversion giveths with one hand and takeths with the other. You will have the power and proven reliability of a V8, but your car wont handle quite as good. You guys like to blow the handling issue out of perportion. You have to remember that 50/50 is still acheivable, and while it may not handle as good with the V-8 due to different perportions and the location of the motor, it will still handle damn good. It's still an RX-7 chassis and suspension boys, so its gonna handle good. I just stopped worrying about that ****, I mean who really cares. I once scorned people for putting a V-8 in their RX-7. I tried to find any reason I could to convince them that it was stupid and wrong. Well I got a ride in a 420+hp small block 2nd gen and now my opinion has totally changed. In fact I am likely going to be the proud owner of a v-8 RX-7 in the next week or so. Im to resposible to use the RX-7's handling abilities to its fullest on the street, but I will sure as hell light them tires up and kill some hondas, and vettes from the stop light.

<snip>
i was just thiking of putting a aluminum v8 into it. and hey more power, and less money in the long run.

sure you will aaron :)
sure buddy,
ill se you in the spring....o wait beater meet
my uncle just got an 86 NA with a racing engine and trans out of one of those dirt modified cars.
600hp minimum,
when i got down on sunday ill get some pics and post them for the v8 rx7 ppl.
Everyone else:
I respect the rotary and it is a wicked engine!, but i don;t have the $5000+ to put into it alone so that it has as much power as a aluminum v8, the v8 is cheaper and has more power.
the rx7 is a great car.
Im sure the hadnling would be fine, once you get some stiffer springs and some good shocks it should handle the same.

Rotary engine is the best engine in the world...... when its running right. Needs more research and developement! Its also to damn expensive to build a motor you can count on.

November already?!?! Time for more V8 RX-7 info.

The minor handling you will lose with a properly done V8 swap with aluminum heads won't be significant as stated. 85% of the people on this board can't drive their RX-7's to its handling limit anyway so the minimum amount that they lose they won't notice anyway. 450ft/lbs of torque to the back tires they will notice.
Low mileage LS1 (all aluminum) engines with 6 speed transmissions sell for around $5500 and guaranteed to run. The factory heads flow nearly 300cfm! Add ported heads $1500 and a larger cam $300 and nice exhaust they are putting out around 425rwhp on 92 octane naturally aspirated. There are engine/trans mount kits out which make the swap easier, then you buy an aftermarket wiring harness with everything labeled and what you can't figure out you have a car electrician do the rest. Same goes for an LT1/6 speed but they are around $3500 and weigh 60lbs more and have a decent cylinder head design.
I've said enuf for today..... the V8 RX-7 isn't a bastard car. It satisfies the need for more power that is reliable and cheap. It keeps the looks of the car, light weight, great aerodynamics, and IRS.
All you guys that say the 13B can last 10 years is right... A stock 13B.... once you start putting out good power and reach levels close to a mild V8 you start rebuilding the engine often. Yes.... stock they run for a long time.... any major mods and they are a time bomb waiting to happen.

If I do get this car I will let you all know the handling & braking difference that I notice. It is an SE with TII(GXL,GTU(S) brakes, and no sunroof. So its a relatively light car to begin with. It has a remanufactured 350 out of a 69 camaro Z28 that is pushing 275 HP stock. Along with the full exhaust, air gap intake manifold, and 750 cfm demon carb. Should be anywhere between 300-320 hp at the crank. I'll compare it to my TII, which I will still have.

Brian D. Cain's TII:
Ported TII motor- did it himself... otherwise stock rebuild... About $800 Haltech w/flying lead kit $1300 T04B 60-1 HiFi $800 manifold $300 wastegate $300 BOV $125 Stock intercooler converted to air-to-liquid (requires some welding, a small pump, and a civic radiator- about $200 total) He runs a 3" single exhaust, which I won't include the price of (only about $200-300 from a local shop) since you didn't. Let's add it up now: $3825, or about half the cost. Reliable daily driver, driven EVERY day... 425 RWHP. And the car LOST weight due to him removing extra crap. The numbers for a V8 swap just DON'T MAKE SENSE, when you can do this without all the fabrication and headaches required, for HALF the money, the same horsepower, and it doesn't upset the balance of the car.
The V8 swap enthusiasts need to get educated.

But you don;t wanna mess up your weight destribution!
before i go on im gonna need a few facts, how much does the rotary motor with tranny weigh?
i was just thiking of putting a aluminum v8 into it. and hey more power, and less money in the long run.
so if anyone here has a v8 rx7, post some pics,
my uncle just got a gold colored 7 with a racing engine in it, ill get some pics of that/

You are the one who needs to get "educated", because if you knew jack about **** you would know that you can build a 450hp 350 for 2500$ For the cost of bryan D cains setup that "you estimated", you could have a 500hp 383 with all aluminum components weighing in at about 60 pounds more than a turbo 13b. Brian D. Cain is one of the few people out there who are competent enough to build his own motor, fabricate his own components, and keep everything tuned right. Thats why he isn't in the motor a month club like joe rotor who blows 7k$ buying top of the line everything just to pop it due to mal tuning. Do you really think its that simple to do all that you listed? Its real easy to type about BDCs success, but is it really as easy as you make it out to build a reliable 420+hp 13b for only 3500$. Id like to see you do it before you start preaching it like its the bible. You have no right telling people to get "educated" when you are the one who seems to be ignorant. Take a look around you, people are blowing motors left and right. I'll say it again. If I could afford to build up the 13bT the way I wanted to, and I didn't mind forking over1500$ ever few years to "refresh" it I would, but I can't. Is that going to stop me from having fun in my RX-7? **** NO! See what your stupid little comment started!

Hmm..forgot about the ls1's, the AL block I was looking at was the only one you could find for a long time...and these v8 guys (edit: almost forgot myself in this category...I've been here too long 
) are right, you can build a small block chevy extremely well for pretty cheap, being that it is the most produced engine on the planet (started manufacture in 1955), and has the most aftermarket parts availible for it...also do not forget that horsepower and torque aren't about peak numbers, but how broad the curves are (I've seen "weaker" cars take some fairly beefy motors b/c of that) and how reliable the motor is...
I've listed below most of the work done to my motor (can't give away all of my secrets) but I drive it almost daily, and have put over 75k miles on the motor...when I got the heads reworked at about 55-58k miles, I still had the crosshatching from the bore job on the cyclinder walls, and my buddy george runs a 550rwhp '68 GTO that hasn't had anything more major than an alternator replacement in ~5 years...I love rotaries, but don't down these guys for disagreeing w/you, it just shows your ignorance and/or intolerance...

If I could afford to build up the 13bT the way I wanted to, and I didn't mind forking over1500$ ever few years to "refresh" it I would, but I can't. Is that going to stop me from having fun in my RX-7? **** NO! See what your stupid little comment started!
Show me how to build a $2500 450 HP (not counting nitrous) 350 including the fuel system and headers to fit an RX-7 chassis. You made the statement, let's see the numbers. Oh... that includes the kit to put it in, right?
What about all the fabrication to make it work? I didn't think so. You're counting MOTOR ONLY without carb/manifold etc. not including the transmission, etc. against brian's ENTIRE SETUP. What about running 4.10:1 gears with a V8? Yes, you can do it... but it will suck on the street. You can change them... only about $500 for the gears + having them installed- good luck if you are gonna try that one yourself. Will a stock diff in an RX-7 hold up? FD and TII ones probably would... but I wouldn't want to try it with NA parts. Transmission? Again, TII or FD parts MIGHT be ok... but they were not designed for the torque of a V8. Clutch? Gonna be a mix of parts, or a "custom" unit. $$$$$$$$$ Oh... sorry... I didn't include Brian's clutch in the price I listed... add another $300-$400 to it... he has an ACT 6-puck.Yes, it IS as simple as what I listed to duplicate Brian's efforts. He'll tell you the same thing. His motor is not at all radical- it's pretty mild, it's just well tuned and has a big turbo.
I happen to know Brian pretty well. If you look on my website, you'll see pics of me helping put a motor in Dale Nesty's car... in Brian's garage. He's not in the pic 'cuz he's holding the camera. If you look on his site, you can also see pics of me working on HIS car also. Granted, nothing radical like the Haltech install... but still, I think you can see that I DO have the proper background to "preach" this subject. We've had numerous discussions about modifying the 13BT. It all boils down to tuning. If you shortcut there, you'll be paying a lot more later. I keep saying "what if?" and he shoots me down... DO IT RIGHT OR DO IT OVER.
Fabricate his own components? Hmmm... the air-to-water intercooler he designed, but had it done. (welding, etc.) He'll tell you it was a PARTIAL success, but not that great. It did the job though. His car is NOT that radical, at least from an engine/drivetrain perspective. He's done a bit more weight reduction than I would, but that's personal preference. ANYONE could duplicate his setup with proper care and patience. If you don't believe me, ASK HIM. Is it as easy as typing it all out?
ummm... NO. But it IS easier than an engine swap that will require DOZENS of altered or fabricated parts to make it work properly. The reason people blow motors is that they build the MOTOR but don't address fuel and ignition timing issues. You can't take shortcuts there. DO IT RIGHT OR DO IT OVER.
People modify RX-7s and raise the boost, without addressing mixture and timing... then when they blow a motor, they whine about it being unreliable when in reality it is their own stupidity that caused the problem. I bet I can blow up your "reliable" V8 almost as quickly by running timing and mixture settings that are as far off as those that cause the demise of the typical modified turbo rotary. Care to try it with YOUR V8? I didn't think so...

It would be wierd to see a 7 that sounded like a chevy, it just ain't right. I don't like engine swaps in these cars, but I do have one for sale that would be perfect for that. I do like MOPAR and Vector, and a few other non-rotories, but I still wouldn't drop a Hemi in a 7, if I want that I'll get a Challenger. Also, I hate GM and Ford so its hard to say anything about my relatives race cars and cars, mostly bow ties. Granted you can get parts for the older ones dirt cheap, but you get what you pay for.
Well that was my minority opinion.

FCD + stock ECU + lots of boost = new motor
I agree. The misconception that all rotary engines are unreliable stems from improper maintenance, and improper tuning. It's not a boinger, don't treat it like one.
As far as V-8's, if that's what you're into, then go for it. It's your car, not mine.

I actually know of a guy running a 5 lug n/a transmission in his 10 second 350 powered RX-7 with a powerglide tranny. This car is driven daily, and it has never broken a rear. The reason that the rear holds up better with a V-8 than a rotary is because your not dropping the clutch at 7000 rpm when you launch.

Nothing wrong with its current state of development if you know what you are doing with it
