mmm one day i'll have that too :D

nice! hows reliability?

Have you guys taken it to the track yet? Any times?

His times were posted on RX8PR's thread. 1/4 mile in 10.4. 650+ horsepower daily driven.

holy cow - that's awesome!

^ I wonder if he has traction problems with that much power on an RX-8...

Drool

This car is a daily drive machine runs on 93 octane fuel. with air conditioner, power steering
everithing like a stock , For traction i run on toyo Proses TR1 as soon the turbo reach 5 psi of boost it start to smoke them with out minor effort, in the track trim we use a 10" Slick in a 15" rims.

Rgonza

how much did that project cost you, and how long it took from start to finish......

Did you loose TCS / DSC / ABS? What transmission? What engine management?

Damn sweet. Again I'd like to know the answers to all these questions. :)

:hitit:

The cost Of total from scratch to end is around $7500.00 and project time was 3 mounth, The car have intac TCS/DCS/ABS aND HAVE THEIR TRAMSMISSION WITH FEWS UPGRADE TO MANAGE THIS KIND OF POWER HARDENED STEEL INPUT SHAFT HEAVY DUTY BEARINGS. THE REMAIN ITS COMPUTER WHY? BECAUSE THE CAR NEEDS THE IMPUTS FROM CRANKSHAFT TO OPERATE POWER STEERING, AND USE CAN BUS NETWORK TO COMUNITATE WITH THE GAGES CLUSTER TCS, ABS,DSC AND OTHER SUCH OIL PRESURE, WATER TEMP,AND A/C.
WE USE A MICROTECH LTX12'S JUST TO CONTROL THE ENGINE AND BOOST, THE STILL OPERATE BY OWN COMPUTER.

REGARDS
RGONZA

wait did you use the 20b's native transmission or the oem rx-8 6 speed?

i haven't heard of any beefier rx-8 transmission parts on the market

So you're using a Microtech also? Nice, that seems to be a popular ems.

I USE THE RX8 6 SPEED, WE UPGRADED INPUT SHAFT AND BEARINGS, tHE iNPUT SHAFT YOU CAN SEND THE OLD ONE TO MACHINE SHOP AND THEIR CAN FABRICATE ONE TO YOUR SPECS. THE YOU CAN FIND IN YOUR LOCAL INDUSTRIAL BEARINGS SUPPLY, WE SELECT A DUAL ROLLER SEFT LINING BEARING IT MORE STRONGER AND CAN HANDLE MORE RPM AND LOAD. wE PROVE THIS TRANSMMISSION AND IT IS DURABLE WITH THE EXEPTION OF THE SECOND SINCRONIZER AND 2 GEAR CROWN. MAYBE YOU NOT HAVE PROBLEM BUT ALL DEPENT OF THE DRIVER SKILLS.

The 20 B 3 Rotor Engine Not Come With Manual Tranny It's Come Only With Automatic Tranny, You Will Need To Order A Fidanza Aluminum Flywheel From Rx7 Of 1990 And Use The Clutch Assy. From Turbo Ii 240 Mm. That's Directly To Rx8 6 Speed Tranny Without Any Modifications, The Only Concern You Will Need To Use A 6 Spuck Sintered Iron Clutch Disc And High Performance Pressure Cover From Act. Why? Because The With Mere 6 Psi Of Boost It Fry The Organic's Disc One.

Is everyone taking notes:

That sounds like a quite impressive setup. Do you have a dyno plot? Is the stock RX-8 LSD retained and hardened as well, or did you use an aftermarket unit? Did you encounter engine-mount problems? Weight gain from the 20b+ turbo? Are you using variable-split timing?

Rgonza,

It's Manuel,
Don't forget to call me before friday..................to talk about the labels machine.

All of the members of this forum are great Rx8 fans, and they would ask you a LOT of questions!
Some times they would ask you for proves.......................

Rgonza do it by himself, the manifold and a lot of others parts for the convertion to a 3 rotor......so he saved a lot of money!

I already get a ride on his car and is really fast!

Manuel

I don't need to take notes ....

I helped him resize a couple of pics :) I had to drop them down to 1024 and lower the JPG resolution to get under the 200KB limit. The originals are 2080x1544.

i've never enjoy reading broken english so much lol

but seriously, you guys have some serious juevos down there in PR. people in the states would talk all day about how they could do this or that to make half the HP you do and make a huge deal of it on the internet. you just show up one day with the fastest rx8 in street trim in the world.

im interested in some more details on the rest of the driveline, namely the driveshaft, LSD, and half shafts. also why kind of modifications were required to the front subframe and the chassis to fit the 20b in place?

Don't feel bad but is huevos, no juevos.

I believe that it would be worse if we write in Spanish and all the members try to understand or write in spanish!. In PR we speak english a lot better, write it is more difficult................

What is important that we can communicate and understand.

Manuel

don't worry, 3 rotor is the same in any language

i was in PR last august for the first time. beautiful country with plenty of beautiful women around!

Rgonza, sounds great. any videos.. I would love to know in detail how you did this all.
would like to hear what that sounds and looks like taking off.. Congrats, This is something
I would be interested in doing to my car. Let us know much more...Thanks

I simply cannot believe a Car that looks THAT GOOD has THAT Much Power...I'm SO Happy to see somebody do a huge project like this, and NOT destroy the car in the process. I'm thinking I'll start saving $...ship me and my car to PR for a couple months, and come back with an additional rotor. :D

AMAZING work...Have any dyno plots, etc, you can show?

If you could make this into a kit, you would have a long line of customers.

you puertoricans are amazing when it comes to rotary cars, this right here is the rx-8 mazda should make as the mazdaspeed RX-8 even if they make it NA.

hmmm....all i can say is.....DAMMMN. and it only cost you 7500 dollars? I cant understand this. Props to you guys. Thats amazing

All I can say is...

Coñooooooooooooo!

I can speak Spansih but if I write in it the hispanic people here will always have something to make them laugh here at the rx8club. :)

If I ever go to PR, and I probably will one day since my wife is from PR, I'm going to take a camera to take a video of that MONSTER.

Ohhh mama, by the way how much power do you think it makes without the Turbo? If it cost $7,500 with a turbo how much would it cost without it? While I love power, I really don't need 650HP so I wonder how much power the 3-rotor can make without the turbo.

Great job and thanks for sharing, MY LORD...650HP of rotary heaven.... :evil_laug :icon_droo

The $7,500.00 is basically on parts...............
Rgonza do it this job by himself.
He have on his house a lot of tools and machines
and maked the fuels rail, the manifold, etc, etc. and saved a lot of money...........
He knows a lot about rotaries and this RX8 is his street car he also owns a drag car!


Manuel

holy macro, thats incredible! Congrats and good work there!

:bowdown: :bowdown: :bowdown: :bowdown: :score: :UNCLESAM: :dragster: :smileysex

Man we got to get some write ups from this setup. These type of projects is what will make this car stand out as a big contender. Good job Bro!!

Rgonza was working with me on my warehouse/office today..............

We decide to take a few videos of the car but I need a site to publish them.

The files are between 3.0 and 4.5 MB each one..............

Adrian1 let me know if we can publish them on the same site that we publish my videos.

You would hear the puertorican magic!

Manuel

SOMEONE HOST THESE DAMN VIDEOS!!!!!!!


by the way, did the extra weight cahnge the handleing at all? did the steering column have to be moved?

denward

Oh! The humanity! Someone please host these videos! I got an extra pair of clean pants ready because I know I will need to change the ones I am wearing now, after I watch these.

I can host them tonight. PM me for the details :)

Very nice!! tip my hat to u sir

Manuel, if I remember correctly, the ones you had before were on streetfire. Are you able to put them on there?

:( That means I can't see them until I get home from work tonite :(

:)

^ That IF you put it on right now. Otherwise its another 6 hours from when it is first uploaded.

I would prefer to post them in other place than streetfire because
the other ones that I post over there was very difficult to see them.

Let me know any site where I can post them..................
or any one that give me his email to post them on his site.

Manuel

Check your PM's Manuel... :)

I can host them for you tonite, if you still need. Can you transfer the vids via AIM, etc?

I can send them to your email...........

Manuel

I feel that everyone is crazy to see the videos! :Freak_ani

be patient!

I'm sending them rigth now to nemesis.............

I would send two files of 3MB............it would take sometime beacuse I don't have DSL on my house.

On the second video when you hear Robert say something in spanish "cien millas"
that means,
one houndred miles.......... :evil_laug

Manuel

I finished to send the emails to Nemesis8......................

Now put the pressure on him!


Manuel
