Just wanted to say thank you to Dave @ SPEED1 (formerly KDRotary) for creating one of the highest powered street-legal rx8 around. Saturday I picked up my 2005 WWP Rx8 GT and drove it home from PA. Final Results were 423rwhp @ 20lbs of boost.
Dave & his crew did a fantastic job of swapping out the renesis with an FD 'block' and rx8 front cover, Still utilizing all my factory gauges, a/c, alternator, sensors, etc.Around town Its a 16lb setting with 363whp, pump gas & meth kit. After all the hardships I had turbo'ing the original motor., im finally at a satisfied benchmark. The motor is capable of plenty more, however the turbocharger is definitely restricting its potential. Pics will be posted soon, engine bay needs a thorough cleaning first and some minor visual tweaks. Having my own performance shop, dealing with so many so called 'tuners' and 'techs' Dave is second to none. After almost getting burned by a previous shop, Im so glad it fell through and was referred to Dave & his team of rotorheads. Dont get me wrong, there were drawbacks.... TIME.. Yes it took a while to complete, but running a business as a manager,tech, cashier, advisor, biller, etc... leaves very little time to share, and the amount of time spent talking to customers is crucial. GREAT WORK TAKES TIME. And thats exactly what I got. A guy with a parking lot full of bruised and broken RX's need a lot of careful attention. And yes.. It cost a lot of money to get to where I am, but with his VERY FAIR labor rate and his knowledge of these unique machines... I wouldn't think to go anywhere else. Which is why I drive over 2 hours to get my Mazda serviced right.
How does it drive?? Like stock, with more than double the whp than the day i bought it (180whp for those unsure, and thats after intake,exhaust,clutch,& flywheel). / Now @ 512 bhp
A Thank you to SOL, who got me into the Queens Rotary Meets... although he now owns a Scoobydoo WRX...(cough, TRAITOR,cough
And Once again... Thank You Dave & the team @ SPEED1

congrats sounds like you got great numbers

 

looking forward to the pics!

 

Interested in pics and details of the cooling system. Oil coolers, intercooler and radiator setup.

 

Congrats on your FD swap and RWHP. So glad you didn't go with a V-8 and kept a rotary soul.

 

Factory Radiator & oil coolers. Mazsports Fan Mod & MSPEC I/C from Type 3 Turbo kit. Car stays @ 179-185 degrees with no drama.

 

wish i could see the smile on your face!
Congrats on the swap.

What ECU are you using?

 

So thats a FMIC? For the street you should be fine, but chances are it would overheat in under 5 minutes on a track or very spirited driving. There is just no way that the factory rx8 system can keep up with a motor producing more then double the power. Larger oil coolers and a secondary radiator would be required.

BTW I am not trying to be critical, I would just hate for you to have a problem and do damage to something so beautiful.

 

Congrats. Also looking forward to pics and videos..

 

deta1ls, we needz moarrrrrrrr ...

 

as we say here pics or it never happened

 

okay since no one asked, i'm gonna how much did it cost :D

 

Wheres your evidence to prove that statement.. Ive dragged with it plenty of times, autocrossed it a few as well. Never had an issue. Please support your statement with proof. Theres no possible way the factory system was overefficient? I watch my gauges very closely. Spirited driving for over 5 minutes with no overheat. It works. Sorry to disappoint you. Find me a vehicle with a similar setup where this has a occured. You cant, because there isn't .. making your statement based totally on your speculation.

 

Factory ECU with Interceptor/Microtech - updated with a 3bar boost map

 

I drive my car HARD all day with no problems either, and my....mm...(thinking)... my. mmmm, my wipers are still stock.. ( thats one of the few things still stock in my car)
Hope you are enjoying the car my friend, thats what its all about.

 

Amount... Could have been done for 15K, Had a lot of options, Still under 20.. thats all I can say had a lot of parts going into the swap.. originally, had the type 3 turbo kit from the late Mazsport.


\Thanks for support Angeljoelv..

BTW love your setup.

 

Job was completed last year, raced it around. couldnt get traction down the dragstrip. Spun 1,2,& some of 3.


Had car retuned with race fuel. And Line-lock installed. Made more power with 1 lb less. Car runs beautifully.
The queens guys have seen the vehicle and no its a sure thing. The original goal was to maintain driveability and make over 400w.
Mission was accomplished.

As far as upgrades.

Engine XCessive Manifold (an rx7 thing), watermeth, t4 single turbo Hks manifold on13bREW. Low compression, rx8 front cover, every single piece of metal was cryo treated. RA SuperBlack Seals. Microtech 4bar software (1vac+3boost) BLITZ Dual solenoid Boost controller replaced my Greddy Spec2 after it puked. THE BEST electronic BC I have ever come across
Fuel system ... a must. Obviously. Injectors from Type 3 kit.My walbro is actually starting to fail.. aeromotive 340 will be going in Wednesday

Cooling.. fan mod only. Car runs 179 and Ill beat the everloving **** out of it, only to yield about 10degrees before fans drop temps back down. Your setup may need a huge extravagant radiator! Mine, does not. And I can put my money toward other required areas. It was fine Stock. It was fine with Type 3 turbo on renesis, and its most certainly fine with rx7 engine......with the Mazsport Fan Mod.

Clutch. 6 puck sprung Extreme ACT. After ripping my stage 2 to pieces the puck clutch is holding up beautifully and still pleasant in traffic.



Suspension Mazdaspeed Sways. Stock spring/shocks.
Autocrossing proves the suspension is soft. But for Drag... its fine.
JIC tracbars drastically reduce the wheel hop.

Brakes: Mazdaspeed pads, stock rotors... Already changed rotors after autox.
Fine for everyday..

 

OK, so now we want pics.. We know you have them..

 

You guys are brutal.. Heres one from November.. No engine shots yet till I clean up. Period.

 

Like I said, I was not trying to be critical and if it is working for you, then great.

My proof is that a stock na rx8 on hot track days will overheat or almost overheat. Anything less then a perfect it will overheat. Every single turbo or supercharged renesis with a fmic overheat on the track unless upgrades are done. Gen3 rx7's have larger oil coolers then an rx8 and track guys upgrade both the radiator and oil coolers to keep oil and ECT's down.

Its just just irrational to think doubling a cars power and mounting a fmic while keeping the cooling system stock will not create a cooling problem.

Street, drag strip, autocross and spirited driving do not compare to true track driving.

If you are monitoring everything and its working for you, then that's great. Honestly, the lower compression motor equates to lower temps but just not THAT much.

 

I need more details haha. What custom parts did you do to accomplish this swap? Custom motor mounts and custom UIM? I love the fact that you are able to use the stock ECU.

 

I am in no way trying to provoke an arguement. Its more of a discussion. Prior to the engine swap, My mazsport kit never saw an overheat, no matter how hard I pushed the vehicle. not even close. True track driving? MAYBE it MAY overheat....but maybe not. I spared no expense on the car, If the situation called for an upgrade; it would be done. Your saying that 'true track driving' calls for the highest demand out of the cooling system. Did you run the mazsport fan relay to try and disprove the theory? I see no reason to upgrade a system that frankly, runs perfect in every aspect I have put it through. I am confident I can 'true track drive' it and the temps will stay stable. If not, at that point, a radiator may be necessary. What I dont understand is how autox does not require as much demand as your 'true track driving. If the vehicle is going to be held at high rpms, with low speed for a significant amount of time, How would that be less 'true' to a track that has a long distance to catch ram-air, more braking points where rpms drop. Even oil temps, yeah they get hot. but the mazdaspeed front bumpers large openings, along with myself trimming the blocking rubber oil cooler shields have shown that maybe those aftermarket solutions may be not be as necessary as we should. I have seen people put rads in mildly modified rx8's, and fans on there twin oil coolers thinking its the right thing to do... When meanwhile myself, and im sure others, are running the factory PROVEN components that are throroughly tested to BLAZING temps, in there FI or heavily modded applications, assuming fitment wasnt the issue, without drastic measures.
Its all the people out there saying. CHANGE THIS part, because its weak, AND CHANGE THAT PART, because its not as good as this. When truth is.. its just fine! As i previously stated. I run my own high performance shop, and change lots of parts that have been modified and upgraded. Ill install anything you want me to put in..But, I'll give an honest opinion to my customer if I feel the part is an absolute waste of money, no matter how much it cost them, or if the part should be returned, and money spent to a more necessary solution accustomed to there specific build... . And its mainly based on customers use of the vehicle.. And there obviously are weak parts out there, and better mods, but is it necessary for the specific application. There may be a better cooling system, but I dont need it! And judging by all the mods I have done and many forum members on this site have done.. Not many of you guys really need it either. A guy who is road racing, probably wont be interested in a set of Drag Radials. Point is, members shouldn't go around telling people there build is subpar, simply because they feel it is. Have proof, maybe ask if they will ever 'true track' there car, where your radiator will be a necessity, according to your claims.
Once again. Not arguing. Not being an internet tough-guy to you or anyone else on this site. We are Discussing a topic.. Those who want to justify there purchase may be mad. Those who truly needed it, will understand the point. And those who agree, well, dont be afraid, to chime in and speak up.

Motor mounts are solid.. Originally were the mazsport mounts. Since the new block was put it. new solid custom ones were machined/fabricated. 3rd gen UIM
J-spec version (no emissions component) Greddy Elbow to the factory throttle body, Drive by wire. Tial 44mmWG and HKS ssqv BOV. BHR Spacer accomodates the meth kit which is in the trunk. Deleted the OMP, so premixing is necessary. Mazsport dual resonated midpipe is on with straight pipe to the tips. stock ecu, stock waterpump, alternator,ac, greddy underdrive pulley and 6 fuel injectors total.

 

The only thing prone to breaking on the stock radiator is the top plastic piece which is what I read. Other than that im sure its quite good to keep things cool. I would do a remedy water pump and thermostat though. Dont quote me on this though.
