Oh the agony of decision! V8 or Renesis? It burns...
#51
you sir are very wrong. it is a bolt on putting a v8 into these cars. since it has become so popular to ditch the 13b for something a little better, companies have been making a killing selling these kits to people. takes literally no fabricating at all to stick a v8 into the car. al lyou have to do is know how to use basic tools and you can do a v8 swap. no need to create a craddle foe the rx8 motor. and hell if youre scared of wiring a sbc needs like 4 wires to make run, talk about simplicity, no need for a ecu or anything of that sort
and also when the v8 is in the car its positioned pretty far back. its not like all the weight it over the front wheels. you can still keep the 50/50 weight ratio if you do it right
see i told you they were gunna be up your *** to keep it rotary powered.
oh and also whoever said the 6 speed would be an upgrade, go hit tjhe books. its not

wow,so much mis-information here.and so much BS.
Yea you can find a 20b for 3k,but can you get it running for 3k? I dont think so.
You can make a LSx or 5.0 run and drive for 5k.
Flyboy-just do some research bro.and you make the decision,dont let people with negative comments influence you like such-
"also a renesis is more performance, my cousin has a 13b 1st gen that destroyed all the v8s in the competition so the renesis should be great"-----ok show us some proof?
"5.0 has been done to death. Also take a serious note at how many V8 Rx-7 projects are always for sale. Because they suck."----WRONG!
and so many other negative comments.Do as you want bro.Let me tell you this,I drive next to Corvettes and Cobras and they **** their pants.When your at the gas station,pumping gas and you crank a V8 RX7 and people almost break their necks to take a look.Im speaking from expirence.

the FFR is NOT faster in a straight line, hence the surprise. it almost keeps up, and then has to shift. he only was able to get past because its 1000lbs lighter and on slicks, rx8 was on the factory bridgestones. keep in mind this is on the RACETRACK too, its not some punk kid, its a guy with a racing license, vs another guy with a racing license. again hence the surprise.
on the street against someone that didn't know how to drive, in the same rx8 i took a newish 911 non turbo, again i was surprised, they were angry!
personally i'm not into the v8's much at all, the only one ive driven that was cool was my buddies ls1 volvo wagon, but hey it is YOUR car, either way pics are good!

my shop space is driveway too! i did a 20B FC, a couple of t2's, the P port...

I have plenty of pics up right now, and there are more on the way of all parts of the build, but DirectFreak has given me the warning that once pistons show up the thread is going to be moved here, which is really very saddening

Haha but do you have the whole driveway? I only have the edge, my parents don't like me even having it there (I'm younger than one might think). I do give you mad props for driveway wrenching, if you ask me the coolest cars are the ones done by people in their garage or driveway. Those 8s are quick, I've seen a video of one catching and owning an M5 on a track, but the cheap power is just too much to pass up.

ive done both, and having the shop is nice, especially with weather and stuff, but either way you still have to work on the car, and the driveway is right there...

Like others have said you kind of have to decide for yourself. You're clearly not a purist (a stance I can respect, if not agree with) so that means your choice likely comes down to ease of the swap and performance per dollar--both up front and cost to own / maintain--for whatever you want to do with the car.
When I did that math I landed on a heads and cam ls1. Sure it's been done but as to the argument it's not "unique" I'm one of 10 or so v8-7s I know of in a city of 17+ million people (Los Angeles) so how unique do you really need to be?
My car makes 462 rwhp and I use it as a daily driver on 295/30r18s. It brings a smile to my face every time I step down. Some folks say it doesn't have a soul. I can live with that. Can you?

and the 7 being the seventh time its been a failure!!!
To re title this thread, it should read: " Oh the agony of decision! Victory or Fairlure again? it burns.
Seriously, go with a Ls1 man. 310whp bone stock and about equally the same torque. Parts are cheap and available, theres TONS of reputable builders and ETC. Best decision i ever made, and i used to have a 3mmm cryoed 76mm single REW with all the bells and whistles. When my rx7 had the stock Ls1 was 10x better then the single turbo rotary setup inside and out. Go figure i made about 340whp with all that jazz and it still blew up after 4,440 miles on the fresh rebuild. Stock ls1's simply dont blow up unless you use sand for oil or something rediculous causing such a failure.

You ought to drive a car that's already been swapped, of course, finding a Renesis swapped car will probably be a lot harder than finding a v8... but this is coming from a hardcore rotary guy for the last 5 years. I love the car with the rotary... but I think I'll like it even more with a v8 All it took for me was one drive in a swapped car (and it was basically a bone stock ls1), and I was sold. Should have come from the factory like that.

LS1=ak47
Rotary=glock
They both get the job done but the ak is still gonna keep on shooting long after the glock blows up in your hands.....
I dont give a **** what "rx" stands for. they're shitty motors for people with low budget and high hp goals. I love em to death. I have fun with mine but LS1>rotary. All day.
If you're talking a pp 20b or pp 26b, that's a completely different monster and i'd take either over a piston engine because they're ******* boss and dont need engine-blowing turbos to kick ***. 26b is a pipe dream for most of us....

Now to the OP.... skip the renesis. The renesis is nothing short of lame. Yes its a good lil' motor stock and can pull a few cool tricks, but the older 13b's put it in a headlock. I say build a 13b 4-port from either a T2 or 13b-re and make more power n/a and for much less effort. The 13b-re in my daily driver is at 230rwhp and I do not have any money in it at all. THEN if you decide to supercharge it, the engine will ACTUALLY live a really long time. Cant say the same for the thermal heat trap the Renesis is. And on the v8 regard....... LSx or nothing. The Ford engine takes some work to produce even stock LS power. And it is a cast iron behemoth at that. My two cents..

that's a good point. its not technically true, mazda has published a couple of SAE papers, and new model training books that really explain everything on the engine, they really even gave enough info to have a good start on programming an aftermarket ecu. it would take a lot of time.
the other story i have, is my friend was taking me around infineon, and we came out of turn 11 right next to us was a factory 5 cobra. to our surprise the 8 pulled on the factory 5, all the way until after turn 1. the factory 5 is 2000lbs, and on slicks, so it should leave a showroom rx8 in the corners.

Interesting. The FF has *terrible* aero. Their lap times and overall performance suffer partially b/c of that. Wonder how much that played into that.
Back on topic. For a GSL, I'd go for a Renesis. That car is nice and light and simple. A nice rotary would be fun in a light chassis like that. I think the V8 would be overkill power wise and would require too much effort to drive all out and too much suspension and brake work.

You and me both :P
And what a beast is! I urge everyone reading this to check this guy's build thread. I'm with you on the "unique" thing, I have yet to ever see a V8.7 in person and I've seen more than a few cars.
Agreed, I love rotaries and if I had big moneys I would do a ported 20B or bigger and jizz my pants every time I drove the car. But I don't.
I can't say much other than check my build thread. IT'S TOO LATE
It will take some insane effort to wring out and not die, but that should just make it fun. If I need more brake I'll do the FC swap, and my heavily upgraded suspension can handle it, should only be another 50 to maybe 100 pounds toward the front overall.

To blow up a 340rwhp 13b with 3mm seals in a bit over a oil change takes some REAL skill. Seriously you would have to TRY and TRY hard to pull that one off. I have no idea who touched that setup, but keep them away for a while. Or better yet for good.
