i was talking around the shop today and we are all pretty confident that we should attempt it.

my question is: who on here would buy a complete renesis 3 rotor kit if it were available for lets sayyyy... 15 grand, if it put out 300+ N/A? a stock 20B can put about 230 in N/A form and can pretty easily reach 300 with some mods. the renesis already puts out 180 in N/A form, so 300 shouldnt be too far of a reach, if one at all.

it would probably cost a very experienced rotory shop a good amount of dough to install it as well. unless we decided to install them.

i just want to see who would be interested.

For that kind of money, I would send my car to rgonza

Yeah, I know this is probably completely unrealistic, but I would pay ~$12 (parts and labor) to get an RX-8 to 300whp+. Of course, having a turbo in addition for that low-end kick would be better. I know I could get better cars for that price and blah blah blah -- the RX-8 is the car for me.

My main problem is that I wouldn't want to void my warranty. If I knew a dude that ran a rotor shop down the street then it might be different. I'd feel confident that things were done right and that problems could be handled without a huge cost (maybe just parts or something).

But yeah, rgonza got to 650whp with minimal turbo boost for well under that price (parts only). Granted he's in PR so it's not exactly down the street, but it's still awesome.

I think I would make the sacrifice.... So I would say yes

Raptor2k

15k? nope

raspyrx7

$15g installed I'd consider it... depending how much I could sell the stock motor for

I'm with abbid on this one.

drivelikejehu

me too but 400 is gonna cost you alot more than 15. my FD alone was 15 with 40k on it. a friend of mine spent 24,000 (not including the car) getting his FD safely to 400 at the wheels.

who would do it for 12 grand?

As the club president of the 3-rotor dreamers club I would be REALLY interested in this, but like everyone said (and as president of the cheap modders club) 15K is a little steep.

Can I offer a suggestion...two possible alternatives:

(1) You sell a DIY kit that gives the customer all you need to build a 3 rotor with his/her own Renesis as the major parts source

(2) You bring in the customers 8 and build it for the customer by using as much of the customers Renesis as possible

Both those option would keep cost down and bring you ALOT more customers!

According to the initial post, the $15k would only be for the kit, not the actual install. The total cost would be completely absurd for the hp gain.

drivelikejehu

its cheap considering a professional install of a 20B into an rx7. last i heard Peter Ferrel charges about 35 grand for a 20B conversion into an FD. your looking at a completely new subframe, intake and exhaust manifolds, ecu, cooling system... the list goes on...

300 is just a guess, it could be alot more than that, nobody knows. its never been done. i know its quite easy to reach 300 in a conventional 20B, so honestly, i believe the renesis will yield much more than that.

i think 12k (which is also an ESTIMATE) is pretty reasonable. your getting 300(+)hp thats all motor, no turbo, no boost guage, just power. IMO, id rather spend the money and have 300hp that i know is going to last years and years, rather than spend half that, double my hp, and have to rebuild every six months. more boost = more problems. keep it simple. and if you REALLY wanted to spend some cash, you could still slap a huge turbo ontop of things later down the road.

im not trying to argue or anything, but theres alot more to good power than just dyno numbers. i do understand that everyone spends their money differently, and i respect that.

i shudder to think of the inverse relationship that HP & gas mileage have on a 3 rotor engine...

yiksing

Too expensive

rx8wannahave

There are ways to lessen the blow, like going from 4.44 to 4.11 or 3.90. Not sure its possible but with 300+ HP our gearing doesn't have to be so aggressive.

drivelikejehu

gtorx7 on the rx7 forums has a street ported N/A 20B that has all customs manifolds and he says he gets around 17-18mpg with a few trips to redline every time he drives. he pushes 315 to the wheels and has P Ports that havent even been opened up yet.

this car is HEAVILY modified for drifting. the 20B renesis we build will be designed for everyday use in an everyday rx8 (or rx7). the gas mileage on a renesis is MUCH MUCH better than the previous 13B or 20B. the side exhaust ports completely eliminate port overlap, improving efficiency greatly.

15 grand w/out install isn't worth it, you can probably put a covette engine in there for less money and you get twice the power and twice the torque. I know it's not a rotary, I'm just comparing what you could get for the same price.

I think it'd be cool to see if it could be done though, it's an awesome project, and then mazda might get smart and make a 3 rotor version.

and if we get really lucky we might see a mid-engined 4-rotor mazda supercar that would be something like the NSX... only with a rotary... *droooool*

RotaryManiac

15k no. 12k no. thats just too much to spend for 300hp, especially if that doesnt include installation.

mike1324a

I love the idea. I cant afford the price but it is the first step toward an 4- rotor Renesis and that would be worth seeing. I dont know if this is feasable, but why not build a first 3 rotor renesis and then attract customers from that. People are turned off to the price but i think its becasue they have yet to see any form of results.

hondasr4kids

for 15K you get a 20B installed and running in a 8. That is with your choice of turbo and tuning.

Now, it be nice to show Mazda what a 3 rotor renesis can do.

IZoomZoomI

wow 12k... thats a hard pill to swallow. But well worth it, collectively i've already spent that amount on mods.

DARKMAZ8

A 3 rotor n/a is a great idea and something I have been considering for a while now. Of course, for that price you can find other means to make that kind of power but the 20b just sounds incredible. Plus, 300whp without a turbo would get a lot more respect and you can always add a single turbo to the 20b if you want 400+.

My only gripe is the fact that the renesis is still in the early stages of FI and I feel that ditching the renesis is not giving it a fair chance. I really like the renesis for what it is and it really depends on what goals you have. I think that 300whp will be enough for a 12 second 8 and that is enough power for a street car imo. If you want astranomical hp, then the 3 rotor is the best way to get it but I believe the renesis is more then capable for all our 300whp goals.

Unless you do all the work yourself you're not going to get a 20b swap done for 15k.

DARKMAZ8

sure you could. The 20b swap is wayyy easier with an rx8 then an fd(more space). Plus, it's not an exotic swap like it use to be. In a couple more years I can see this swap done for even less.

rx8wannahave

I hope we don't discourage them, I think they can tell that this is a universally loved idea. I prefer NA power which is why I'd love to entertain the idea of a 3-rotor Renesis but the price is just not at the sweet spot.

drivelikejehu...how about my idea's to bring down cost? Please please please make this possible.....just thinking about it....

drivelikejehu

oh dont get me wrong... it WILL be done. now selling kits was just an idea, and the purpose of this thread is just to kinda see who would actually want to buy something like this. no offence to the rx8 owners out there, but its a much older crowd, and the majority of you arent looking for (or need) something like this.

im not trying to keep this a big secret, but rather progress rotary technology. if anyone has ideas suggestions or solutions to problems that are unforseen at the moment, feel free to give your 2 cents. hell, since we dont have an 8 at the moment to put this engine into, if anyone would like to volunteer their car to be the first you would walk away with the worlds first true 20B renesis... for free.
