No that turbo costs about 4-5k and it's probably what I'd suggest for a 4 rotor. I don't know if your twin KKK kit thesis is going to work. Not with 2 seperate manifolds. Did pineapple say anything about it?

If I was running a 3 rotor with BP , you better believe a Turbonetics T90-T100 would be strapped to it.

 

All this 4-rotor talk seems a tad ridiculous.. I wanna see the results.. pics, dyno, more pics.. not to mention an engine managment system for 4 rotors... man i doubt you final cost for everything is goign to be around 25k...

 

If you are serious about doing a 4 rotor, contact Jeff Bruce in New Zealand to have a custom eshaft (and modded center/intermediate housings) made so you can make a 4 rotor out of 13B parts. You will have to make your own intake manifold and exhaust manifold - but that is within the capabilities of any custom race shop.

Sorry, here is a better link.

http://www.hitman.hm/engine.htm

The eshaft for the 3 rotor version he does is $700 US if I remember correctly ( or is it $1200? Can't remember but those two numbers stick in my mind)?

 

he is just dreaming. about twice a month, there is is always a newbie asking about engine swaps and things of that nature that they read in a magazine.

dont hold your breath for pics and dyno numbers because there is not going to be any. this is no different that the average newbie with one post asking "How much for a 3-rotor swap? its just about $3,000, right?", but this just involves an extra rotor.

i am honestly surprised by the number of replies this thread got in such a short time...

 

and BTW, good luck with the 26B conversion!

 

Joe,

Do you have to be a jerko** all the time? You were once a newbie. Just because you have 4000 posts doesn't make you an expert, not to mention the fact that you don't own an RX-7.

Do you know for sure that this guy doesn't have the cash to dump into this project?

If you have nothing useful to say, stfu.

I was going to hold my tongue until I read your latest post.

Good luck codaxx, and definitely call around, and give Jeff in NZ a call. Someone will make you what you want, you just need a wheelbarrel full of cash. Ask Jim LaBreck!

I did quite a bit of digging into converting to a 4 rotor. It has been done to an FD by the way. But I don't believe there has been a turbo 4 rotor in an FD yet. When it came down to it, it was the novelty that made me want it...sense took over and I have started the three rotor project. Although I still think about what could be with a PP 4 rotor...the sound alone would be outstanding.

The logistics suck. You have to cut into the firewall. You can run a relatively basic ECU...but you will not get any split. If you want split you will have to patch a couple ECUs together because (as far as I know) their are none that have eight coil drivers...maybe you can run enough of the optional outputs (on Motec, TEC, etc.) as coil drivers to get the split.

DIY for $25K is optimistic (I'm not going to say that it can't be done). You will need to spend about $5-6K on a transmission (that will take the power). Pineapple charges about $7500 on the 4 rotor conversion of your 13B (I would go ahead and spend another $2K and have them dry sump it). You will need a custom differential, driveshaft, turbo, turbo manifold, exhaust, intake, intercooler, ignition, fuel pumps, injectors, full roll cage (for safety and frame strength), maybe tub the rear end (to get some meats that will hook), BIG tires, serious suspension work, HD clutch, proper shielding between the tranny and cockpit, plus all the small stuff that comes up...

If you do get started, drop me a line...I wouldn't mind helping if I can.

 

Hurley rotary who make the racing and 3mm tip seals claim to make a Quad and even 6 rotor conversion which are listed under their 13b engine rebuild options.

I have no dealings whatsoever with this comany altho - I will say some of the tuning house that specialize in other perforamance marqes in the UK are often very creative with their promises (cosworth aside) from the looks of it the HP output is somewhat less than you want - weather that is a NA figure im not sure.

Sorry bout the time between posts.
Joe just for your info I do have the money to do it if it is feasable. Current car list owned owright by me so shut up before I squash you with any of my cars.
2002 Audi S4 Last Dyno Power Result=440Hp
2002 BMW M3 Last Dyno power Result=475Hp
93 Rx7 Last Dyno Result=455Hp
2002 Nissian Xterra Supercharged=420hp
S14 with RB26DETT motor swap =600 Hp(done myself)
Sorry To be an *** and and brag.

Atihun Thanks for tellin joe off before I got a chance to do it properly.

One reson Im shooting for 25 K is im doing alot of work myself being a fully certifed Mig,Tig,and Arc. I have a Tig in my garage. And a 4 post lift. That is where a lot of the cost is.I do a lot of work for my friends. And have done quite a few swaps making my own soild engine mounts.(not as hard as it looks. But doesn't look the prettiest thats on the bottom.)

For engine Mangement Pinappeal Says his 26B is 2 13b bolted to gether so all I have to do run One engine managment for each 13 B. He said the Twin Exaust would work quite well. This is looking very good and not as expensive as it orginally seemed. Abount the same as a nice pettit racing 3 rotor conversion. But a lot of work done myself. It looks good. Look for the first 4 rotor turbo FD next spring. Yes there will be dyno. And I will do It just cuz people say you cant. Ill be doing the welding myself and probibly motor assembly. Any other good suggestions please post em. Thanks for the guys that want to support it. Thanks for the help. The only issue left would be rebalanceing the chassis. Mabe have drop in weights to balance it. Take em out for dragging In for road racing? Just a thought. Probibly have to loan the car out to a hot shoe cuz I cant drive it. I Drag. He wins Races with Turns(Bah).

Thanks For the help

 

Hey Joe sorry to jump at you. I get tired of the never been done so you cant.Sombodys got to try it. If works easy ill make kits for people at cost. It seems that some people can closed minded.

You never know the 4 rotor might become like the 3. You alrady screwing you handling when you dump the 3 in it might as well smash a 4 in it.

Also dont be looking to soon for it. Im driving my seven this summer then im tearing it apart to start the 4. Its been decied. It all be fun. If workd well. Well have a meet and all take drag runs in it. Who crashes First will be the real question

I dont know where you live Joe but Im in Nevada.
When its finished anyone is welcome for a ride and people with crediable driving record are welcome to take it for a spin. Whats the fun if you cant share what you got.

Driving this Spring

 

codaxx... good luck man. Keep us posted(the ones who care). dont know about driving it.. but I sure would like to see it when your done.

 

So what? Every now and again one of those guys builds the damn thing. I'm not saying codaxx is for real but does it matter? NOBODY on this forum has taken the time to calculate exactly what is required to do a four rotor conversion, least of all you. People have offered estimates but I doubt anyone has gone anywhere near measuring up a mock-up.

Becuase some people come here for fun. It's most FD owner's dream to have a big displacement rotary so talking about what's involved is fairly harmless.

As far as I can tell you don't even own an FD. That's fine but could you tell me why you come here? Do a quick search for your username:

https://www.rx7club.com/forum/search...der=descending

You'll quickly see that all you do is come here and bitch.

-pete

 

More power to you man, but like Joe, i'll beleive it when i see it.
Thats quiet a task your undertaking.
If i was rich though, i would be doing the same thing...
Man, if only i was rich, i would learn to weld and fabricate ****, and spend every waking hour in the garage....

 

Can't argue with you there

 

hehe, just finished reading page2, wow buddy, where on earth did you get that kinda cash (certainly not being a mechanic, hehe)

I'll say one thing...with a list of cars like that and your admiration for the Rx7 and Rotary Engine, I'd say you have your priorities in order

 

Stocks Make the world fun. And some Side busisnesses

 

Legit bussines.

The one issue I spent some ime thinking about is the weight balance issue. I taked to a mecniacal engineer. He said weight would dramaticly affect the handling more than the front bias would. His thought that the front weight bias would only be around 55-58% of total wight. Not too bad for the power gain. His suggestion was a tube chassis up front to balnace it out. Lot of money though.

The rorotay Rx7 is the best performace for the money of any car avaialable IMHO. I drive it more than any of my other cars. And my rx7 is my only car my friends arn't allowed to drive. All the other are fair game.

Yeah my friend just fender bender my BMW insurnace gets the bill on that one. My guess 5g's. Ohh well **** happens.

Also I im not total rich I Just love cars. And I spend all my money on them. Hence my obsennion cost me a nice house and a girlfriend they date me cuz my cars and leave me cuz all i do is work on em.

 

And a healthy imagination doesn't hurt either, right?

Sorry, but until you cough up dyno sheets and pictures for all of those cars, I think you're full of **** too. You did save enough money for a digital camera, didn't you?

Not one but three 2002 vehicles and you've already modified them all to 400+ horsepower? Not to mention ALL of the vehicles you listed apparently have 400+ horsepower? Mind giving us a mod list for the M3? I'm sure everyone would be interested to find out how easy it is to modify the M3 to 475 horsepower. How about the S4? I have friends with S4s. I'm sure they'd love to find out how to make an easy 440 horsepower...

And its funny how all your numbers come out perfectly even, rounded to the nearest 5... I figure someone who knew how to modify so many cars would say something like... 355.8 RWHP. See, my Z06 has actually been on a dyno... have any of your cars? Or are you just pulling those numbers straight out of your ***?

Joe's right, you're full of ****. If you were as savvy about modifying cars as you claim to be, you wouldn't be here asking newbie window-shopper questions about shoving a 26B into an RX-7 "just because you can" or bragging about your money. You'd just find someone who could do it for you or help you with it and that would be that. I'll grant you the RX-7... anyone with "stocks and side businesses" (or who flips fries for McDonald's) could afford to finance a 3rd gen. for $15k or so. The rest of it? Riiiiight. And saying that you're capable of a 4-rotor swap because you can weld is just... lame. Extremely. Personally, I'd be embarassed as hell to have said something like that.

So I'll believe your 4-rotor swap when I see it, just like I'll believe you have a 475 horsepower M3 when I see pictures and dyno sheets for it, and I'll believe you have a 440 horsepower S4 when I see... you get the picture. Literally. Go get some pictures. Prove it.

If you'd showed up asking intelligent and humble questions to gain knowledge about a 4-rotor swap, that would be one thing, and I'd side with the people who told Joe to lay off, probably. But the first thing you did was swing your "money" in people's faces, claim it was a cinch because you welded something once, and then tried to blow Joe out of the water when he called you on it by listing a fictitious stable of incredibly modified cars that you apparently got with stock proceeds or whatever. The M3 alone would have set you back $70k with mods easily, if you'd paid cash. I don't know too many people making money on the market these days... want to clue us in on your secret?

No, I don't believe one ******* thing that you've said, and you might as well pack your **** and leave if you don't have pictures, mod lists, and dyno sheets to back up your claims. Anyone with a list like that and the apparent knowledge of how to super-modify not one but several types of cars should have plenty of documentation, in my opinion. Prove me wrong and I'll apologize, but if you're as full of **** as you seem to be, you will never know a moment's peace on this forum for as long as you stay.

 

 

but really, what gave it away that you really are BSing, or have no clue as to what you are getting yourself into, is that you are not even thinking about the many, many other one-off and custom modifications you need for this engine to work in an FD. firewall clearance, steering rack, driveline mods to handle the power, etc....all problems that come up even in a "played out" 20B swap, that would just be magnified with a 26B.

and besides...you live you in Reno, Nevada for chrissakes. who the hell would have the resources to do all of this anywhere near there?? oh yeah, i forgot...you know how to weld.

seriously, no different than the typical newbie coming in an asking questions about a 20B swap and thinking its as easy as swapping in a B18C5 into a Civic Si. except people are tired of hearing about 20Bs, and when the 26B topic comes up...everyone blows their load.

and yes, the nice and even dyno numbers did seem a bit odd.

 

Hmm...Squeezing quite a bit of power from both an M3 and a S4.

The only thing I can say is that the RB swap into an S14 is fairly difficult. Not much space at all. In fact, the swap has most recently gained notoreity. The exact details regarding the swap are still closely guarded, but it can be done. I've seen the swaps done w/ all the RB series engines. Not to say that I doubt you, but after installing a RB26DETT engine into the engine bay of a 240SX, there is not that much room to make 600hp out of it. Not to say that it can't be done, but it would be (IMO) pretty difficult given the space requirements. There are also only a few individuals (literally a handful) who have gotten it done and I know most of those people.

With the money spent to make all those cars 400+ hp, you might as well have purchased a Ferrari or Porsche 911 Turbo, etc. The insurance for one of these two cars would probably be less than the sum of all of those cars.

I want to see a picture of the cars lined up!

 

hell, since we are on a damn RX-7 forum, how about you share with us the list of modifications on your "455 hp RX-7", and who performed the engine work and tuning?

 

Ill post the pics as soon as I get home. Im in Tenesse right now. Look for the pics Sunday.
Ill also post the dyno sheets.
Ever heard of APR for the audi I run 108 octane in this.

Mods on the Rx7 kkk stage 2
Haltech
Apex FMIC
Full HKS Exhust
Street Port
19 Psi 100 octane.

The BMW was bought Like that from shop in town Called IVM Inner Velocity Motorsports. Thats their claimed HP no dynoed.

The Motor Was bought From motoRex. As a tuned setup with new turbos rods and pistons and EMS.

Anything else Joe D

 

Would a smaller block like that fit easier in the 7s?
