Does anyone else think $28k is a bit ridiculous for this motor? Kind of hard to justify when you can get a 3-rotor for around $5k and make all the horsepower you could ever want in a street car.

Instead of comparing the cost of doing a 4-rotor install yourself w/ Pettit's deal, you should be comparing the price difference between a 3-rotor or 4-rotor install assuming you do it yourself. With Pettit's deal you will get a well-sorted car that's ready to drive. Doing the 4-rotor install yourself, you will probably end up with a clusterf*ck and a 3 year project.

You look and a 650HP PP short block and decide it needs a turbo kit? I think 99% of FD owners would be happy with a NA street ported 480-odd HP four rotor.

I am working on a 20B 3 rotor conversion myself, and thats a big pain in the ***, let alone adding another rotor housing and side housing into the mix. Think about it this way gents, if its based on the mazda 4 rotor 26b (using the rotors and rotorhousings from a 13b) its going to be long as ****. You will have to either adapt the subframe to mount the engine aft of the steering rack. or relocate the steering rack and fab some new spindles to correct the bump steer problem that will follow. So realisticly, your cuttin the firewall too. Fabbing a new tranny tunnel. Doin a lotta trail fitting. so lets say even if you do most of it yourself your lookin at about 2 months of work just for the subframe. and for engine management its going to be a bitch. cause the 26b that i know of from the Le Mans Road racing cars has a variable geometry intake that changes based on RPM and its an NA motor. Yes i said NA. lol. so your looking at another 6k like it or not just for the ECU, like a Motec M8 or the M880. plus the money to fly one of the tech reps out to help you play with it and tune the damn thing at a cost of 600 per day, plus 275 per day of travel, plus a nice fat fee for comin and spendin time with ya. (not like i have done that lol) Don't bother with halteck there. then add about 1500 for the wiring harness alone, plus ignition, add another 500 in connectors.... can ya see where this is going? and i dont know about you, but i wouldn't run a 300 dollar radiator on an engine that cost me that much hell the SR radiator that i have for my FD was 500, so i would go to CR racing to have them fab me a radiator, at a cost of about 1200 big ones. (they make radiators for nextel cup cars and CART racecars). so that leaves us with a helova lot left. so ya still dont have a clutch, so your lookin at an AP racing 3 disc 5.5inch carbon/ carbon clutch, cause anything else would get nuked. thats about 2 grand, a driveshaft would be the cheep part at about 500 bucks. i would laugh at ya if ya tried to run the stock rear end. not to mention a tranny that could hold up to the torque and abuse that the 26b is capable of throwin downabout 500 lb ft of torque. so if you want it to last your lookin at the low end of a hewland Sgt 5 speed and thats 7 grand, but since we are goin to excess we might as well throw in a IGT-C 6 speed and it actually has 7 speeds, 6 forward and one reverse and it was the same tranny used in 90% of the japan GT300 cars in 2002 . now for 11,000 bucks i would say that was a deal lol. but seeing as the SGT is only rated at 450 Lb Ft of torque you might as well get the IGT-C.

so lets just see where that puts us.

-28,000 for the engine and god ***** you the variable intake with the deal, hell lets say its on sale for $26,000
-ECU $6,000
-a$$hole from motec to help you tune the damn thing at least $1200 min
-$2,000 for wiring harness, sensors and other shyt
-1200 for radiator
-$2000 for a 3 disc carbon/carbon clutch, more if you want to have a costom sprung disc clutch made for you so you can try to drive the damn things on the street
-$500 for a custom driveshaft
- and 11,000 for a tranny that wont **** itself, dont forget to add about 700 plus for a costom bellhousing.


-$49,900 without belhousing, subframe or a whole lotta anything.

so lets all sit down and think about this. it might be a better deal to take your FD to acosta and hand them your FD and a check for $38,000 and a couple months later they hand you your FD back with a 500-600 hp 20B on low boost and pump gas with a top end of 800 hp on C16.

cavellm

If I'm giving someone forty thousand dollars to make my car faster, it SURE as hell better run faster than 11's!!!!

rx7ttlm

are you kidding man? lol a subframe that drops it down enough that you dont have to modify the firewall.... first off... no such thing, i know someone here in SD that is doing a 4 rotor single turbo, yes 4 rotor single turbo and there is no way in hell that you could build a subframe without touching the firewall unless you put the steering rack on the bumper. lol. and if your doing it for better performance, why would you stick a 4 rotor in there unless you just drag race, but for the sake of argument, you want to have a 4 rotor road race sort of thing goin on. wouldnt you want to maintain the fuxin sweet ballance the FD has? so move the thing back, WAY back, note get it to close to the firewall and your right leg will cook on long drives in the summer (i know just a little about that lol)

rx7ttlm

cavellm- with 600 hp, sintered metalic or carbon clutch, M300 axles, a couple spair trannies and some 285's outback you could lay down some 10's lol

Gargamel

No need to touch the firewall.

rx7ttlm

looks like ya gotta relocate the steering rack tho. not something I would like to do.

rzograbian

ive seen a 4 rotor on a 3rd gen and i was wondering since the motor sits soo low, how do they change the plugs?

rx7ttlm

reach for the ones you can. but the rest you have to get while its on a lift. lol

Sr20fd3st

wow

Sr20fd3st

wow. 600+ hp on an fd better clear 10's, maybe 9's....8's? i'v seen 3 rotors knock down 8's. a 4 rotor better do the same. our 13b's are capable of 10's come on

EZFD

DISCLAIMER: 1:30 am drunk post


4 rotor engine = 28000

custom manifold = 2500

2 gt42rs = 4000

everything else to run = 20000

severe traction problems = 0

most unique and powerful FD ever = priceless

You bump a 2.5 year old thread to say this?

haha. yes

I have been lucky enough to build a 3 rotor short crank built partially by Kiwi-re . I get this sort of thing all the time with people telling me their mate can put a 20B in an FD for such and such . At the end of the day you are paying for the best money can buy and its all the little things that add up for a reliable tough engine . When I take people for a ride they are simply blown away and can see where the money goes . Yes you can chuck in a 20B but will it last 6 months ? They offer a service for the sort of customer that WANTS to put their money where their mouth is and build what they are paying for . Yes 20B's are great but they have limit when used in standard form ( reliability ) .

That car was Autotechs, if it was from the last few Sevenstocks. Thier four rotor is based off of 12a housings and is not much, if at all, longer than a 20b. They custom grind their own e-shafts. Their first design did not work too well. Since then they have redisigned the e-shaft and that is what wasd in the car as of SS8.

Unfortunately, none of my pics show access to the plugs but iirc, it wasn't that bad.

why dont just go buy a 2006 Z06...save bunch of headache.

Well, if you want inspiration, there was a 4-rotor 510 at last year's sevenstock.

rt turbo

because a turbocharged 4 rotor would eat up a turbo c6 zo6...

Scrub

iTrader: (25)

You might want to think about that.

rt turbo

well, il think about this, the 4 rotor would produce 1000+ hp if built correctly. and the few companies to build the ls7 turbo so far produce in the neighborhood of 800-900 hp. but im sure no problem for the ls7 built to exceed 1000+ hp. i guess it comes down to which actually hooks it up.

tphan

Agreed, but which will last longer? love the smoothess of the rotor engine but it's so freaking fragile...dont know when it gonna pop.

Montego

iTrader: (1)

some people really enjoy projects dude. Besides there is an overwhelming cool factor in building your own 4 rotor rx-7.

Sr20fd3st

i wonder if theres ever been an attepmy to add rotors to a renesis motor to make a 3 or 4 rotor version of it.

Actually that sounds kind gay.

here is my car

As for the pricing, consider this a 720 hp Carbed V8 by AmericanSpeed intended for use in the Ultima GTR is 26,000 but it is drysump.

Personally I think if there is a place to put a 4 rotor it is in an Ultima GTR, there at least room is not a problem and your would be around 950kgs. Also you already would have the best suspension, cooling and all the rest.

That's a pretty big assumption.

rt turbo

dont make assumptions. i mean turbo 4 rotor. if one want o build a 4 rotor turbo to 1000+hp, its definatly possible.

CMonakar

Because it sounds like it is powered by a tractor engine and looks like a glorified Pontiac.


Hey RT I noticed you live in Charlotte. What part?

Didn't the Mazda LeMans 4 rotor produce 1000HP straight motor? Now if you had the money to do a 4 rotor in the first place...couldn't you just mimick their techniques? Especially since from what I've read is they achieved that 1k HP just by upping the revs to 11k instead of 9k which was far less HP. Of course I am talking about a super mechanic team that has endless amounts of money and R&D to be able to do this.

I think you need to research the 787 a bit more

What I think he hints or actually wanted to say if he could type in "english". Is that Lemans racers are always placed with restrictors on the engines that limit horsepower. So without limiations could a 26b produce 1000hp?

Also what do you mean they upped the redline to 11k instead of 9k. They just don't go into the Bosch or Motec or w/e ECU and change the redline and boom 300 hp more! This isn't gran turismo. I doubt anyone would want an engine to run Lemans that produces 1000 hp (Within current LMP1/2 regulations).

All this to say, in my beleif a 3 Rotor turbo or a 4 Rotor N/A is more than any street FD should ever dream of.

1) i am a rotard, but honestly i have seen with my own two eyes a non built ls1 408 stroker w/ a big turbo and etc push over 1000hp/trq and run for a few years and also win the small block chevy with power adders class at hot rod's drag week last year, oh yea it weighs over 5000 lbs http://www.1320video.com/img/album01/67_G.jpg
so its not to take away from the lsx blocks, they are great and there are a lot of them making alot of hp


2) 23a's(12a) are shorter and lighter than a 20b, and i would love to make one some day

3) 4 rotors just sound SIIIIICK

4) screw 4 rotors, its about the 6 rotor!!!
