Building a Mazda RX-8 the right way | fullBOOST 

If you're looking to build a rotary street car, the Mazda RX-8 is looking more appealing by the day. It's a great handling chassis and still comes with a lower entry price. Promaz runs through their optimum horsepower upgrade path for a very special customer. *You can grab some of our popular new 1990s merch here:* shop.fullboost.com.au/collections/1990s If you’d like to be notified every time we upload a video, subscribe and then click the bell icon 🔔 next to the subscription button

I like how matter of fact and calm this bloke is. You know he is confident and knows his stuff. Great video guys

I always wanted an RX8 but they were like 60 grand when new. Fast forward 13 years later where I’m at a car dealership helping my younger brother buy a car. I got bored and stumbled upon a shed full of trade-ins and low and behold at the rear of the shed there was an RX8 in the exact spec I liked covered by an inch of dust. Cut a long story short I took a calculated risk and bought the car for 5 grand. I got lucky and was able to get the car running and road registered with minimal issues and it cleaned up very nicely. It was a great experience. I sold the vehicle after a year, but still reminisce, especially with how brilliantly the car handled. I imagine the FD turbo upgrade would be absolutely epic on an RX8.

Miss working around the corner from these fellas Hearing doritos brings a smile to everyone

What a perfect tribute and a way to keep the memories alive of his brother

5 years ago I bought one of these for $4500 and it had 55,000km's. Even though I'm strutting a 2jz build ATM I still miss the rx8 dearly. what a car...

rotaries are seriously amazing engines, so good to see theres someone out there specializing in all aspects of a conversion to get more rotary powered vehicles on the road, really hope that one day i can experience a vehicle with this power plant its on my bucket list for sure, great video loved every minute

I have to say that I've watched fullboost videos for so many years and Simon seems like such a wonderful guy and like Frank from Dandy and Stix from fuel works he just oozes honesty and integrity, and a sense of calm, and you just know he's going to give you exactly if not more than what you've asked for.. So many shonks in performance shops these days I wish there were more like him.. Great stuff FB and Simon .. 👍

Even better when there's a good story behind the car

one day I'm going to have to ask for some work experience with this man, great workmanship and great to deal with!

Great video on the progress of building a car, can see that promaz and Simon have some awesome packages there for Rx8. Love it how chill he is with all the knowledge and r+d he has done in the past. Had my 12at since 2001 so I know the journey and the fun along the way. More content like this please full boost Regardless of the engine.

Such a cool and special build, always love seeing some rotary content.

Top video! Luv listening to Simon talk Rotaries

Mate this Promaz fella is brilliant. So much experience, seems like fantastic customer service. I wonder what the waiting list is like. This car/engine combo would be perfect i reckon. Sounds the tits too. Really great vid gents - awesome stuff.

Wow 😲 this video is an amazing find. Loved to see the mods for the RX-8

Just wish I could send my RX8 to the other side of the world to have Promaz fully spec the car up. Other option is just move from the UK!!

This is how it was meant to be. I have both an RX7 and an RX8, and I've always said it needed that 13B torque. I wouldn't have ported it that wildly though, seen as this platform would lend itself best as a daily driver

Great vid. Fascinating

Awesome video. Love watching builds like these. I'm currently trying to carry out a more obscure build. Based on the Furai R20B renesis, I'm currently trying to build a 20B based off the renesis engine. Yes the cosmo would be better but I'm interested in trying something different. In the past I've gotten around 340hp/290whp from a turbo charged renesis. So I think the R20B could comfortably get around 500HP. I've been doing research into GSLSE rotor housings that may be able to help me increase overlap by getting rid of the MSP, in which I could use a full peripheral port configuration with. Not sure if this would enable me to use higher boost but I'd have to experiment. If I'm not mistaken a few reasons the renesis struggles with boost is that there's too much heat due to the MSP, the seals are weaker (as they weren't designed with turbo charging in mind), and the rotors have been lightened. I once ran an rx8 at around 20psi of boost. It managed it, but there were early signs of compression loss right away. If I were to use either carbon apex seals or rx7 seals and machine the rotors to fit them, along with GSLSE housings, hypothetically it could handle higher boost 🤔

A turbo RX-8, neat! So you'll be getting 6 mpg instead of the usual 11 mpg lmao. I say this as an RX-8 owner that loves my car! XD

Full boost working with only the best!

Now that's a proper build RX-8.

Serious qu. How are these guys getting around the ADR rules that it's forbidden to put an older motor in a newer car?

How good is that! Got me hooked! I've reached out to Simon already.

how do you go with passing ADR's putting an older emission spec engine in a newer car in Aus?

9:57 Honda k20 gasket on the bench

I have RX-8 spirit R and im looking for this project 😅

Is this possible on a series 2 rx8? There seems to be issues finding an ecu that is compatible

awesome video

My next move on mine 😊 sell my running renesis to help fund the conversion. And it’s black 👌

Love the sound of these Fd's 😎😎✌✌👌👌👍👍

Could watch the "Rotary Yoda" all day fella is a picture of carmness & knowage. More of this pls.. 😎😎✌✌👌👌👍👍 frm the UK 😆

Greetings from Greece!!

Simon is truly legend❤

With the price of fds now this is more viable than getting an old school rx7 If only shipping from aus to the us wasn't so expensive. Getting this or a procharger setup for the rx8 is stupid expensive.

Great video. Great car. Great guys.

Awesome 🍻

What a nice tribute to the gentleman. Hope that this build brings peace and something for the family to cherish in life May the gentleman RIP and May god help the family in their grief! TopGear Season 1 Ep2. The big fella talks about Mazda’s naming for the RX 8 engine. Inspired by “Genesis” and that’s how they came to Renesis😅😅😅 Rotary Genesis 😂😂 lol.

Nice Tribute Car for the Memory of Tim🙏

Promaz is a dreamy place

I have built three RX7 Turbo RX8's so far but..being on a budget I chose to use a different method I simply extended the Bracket that couples the trans to the diff..by adding 2 inches to it on the trans side and one extra hole it bolts right up and, I use a FD Trans..it's much stronger as well..no need for fancy lower intakes .and extra's..and to make more room in the engine bay for the turbos mounted up front we remove the plastic ecu box and lay it up along the right wheel arc then built a sheet metal cover to protect it ..I have used Adaptronics ECU's in two(we left the stock ecu box in place) and in the other one we sistered up the 2 ecu's in the Factory box..But, we used a Haltech in the other RX8 but mounted the ecu inside the car much more of a pain to work with

is it cheaper to add lightness?

Best in the business !

This is the right way

What does a setup like this cost?

I have RX-8 can you say what radiator/intercooler used?

I love Mazda Rx8 .... like i realy like them

I am in the what am I going to do stage, I would like my RX8 to have about 350hp for daily use, the thing I love about the renesis is the on tap day after day 9000 rpm, I don't want to give that rpm up. I understand the porting process with bridgeporting it is generally for higher rpm but not great at the lower rpm and streetporting gives a more smooth power delivery lower down but sacrifices at the higher rpm. The biggest weakness for the renesis is the side exhaust port which will always limit what is achievable reliably. I think for me the way to go is with a hybrid rx8 motor with street port primary, baby bridgeport ancillaries and either supercharger (lower boost higher torque) or leave as na. I just can't seem to find the information on anyone using the hybrid supercharger method or hp for either method. Any thoughts? I just don't want to commit to something that is a compromise on torque, rpm, horsepower or drive ability.

Does this still run a dead head fuel system?

bought a rx8 with this same set up however it has a haltech sprint re computer connected to the OEM computer, anyone know why they would keep both computers? bought with the work done

is this sold as a kit that can be shipped to europe?

good swap, should have come like this from factory

Big fan of promaz

jeez, my buddy got his rotors cut for rx7 seals and then slapped a turbo kit on there for $3k, makes around 350hp

nice video, rx8s are definitely getting cheap now

Hi does anyone know how much for the kits I have Fd engine already 😊

Good God, what i wouldn't give to have my RX-8 in that position. Someday, Mozzie, we'll kick some Time Attack butt

8:34 Thats a 90's 626 at the background.. you just dont see those anymore these days.. all must been crushed away

He lost me when he said you gotta lose the cruise control. Cheers Graham.

That early RX-7 though 👀

Do you guys sell kits

Is this able to be engineered given the engines are older than the chassis generally?

Gonna go boom boom

A noob question, is the rotary run in process the same as a piston engine or different?

How to make a great looking $3500 car run good with $25-30k in parts lmao!

I was looking into grabbing a set of the ignition coils seen here -- too bad they’re about $1k :///

*I'd rather go with the hybrid build, with the RE irons, GSLSE housings, and FD rotors.* Seems like it'd be less of a giant pain in the ass, that an entire FD swap would be. Of course, the headers would be a thing that would need to be taken care of.

RX8 is my dream car, i would love to own this car if i have money.

Great video, although with the Renesis, some ethanol and a tad higher boost, a lot of people get around 415-420whp so limit is higher than what he mentioned.

How much is cost to put FD engine into 2010 rx8

Felix Wankel was a great man.

Does the renesis turbo kit work with an S2 renesis?

Nice build. Surely 13B motors are rare as hen's teeth by now?

When are u going to moontune the new WRX u bought??

damn I want one

Great video. Would hope they would include the cost of the build..I'm guessing not much change from $18-20k..

30k at least from ProMaz, be good if we could all do it right the first time =) Car will be a sleeping weapon Great work guys !

Nice touch with music at the end ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-U28lY3F7nHU.html

What’s the legit conversion cost?

Is this a kit You can purchase through this Company?

Still got the hutch Simon?

Where are you guys located?

if every Rx 8 could talk like the mazda 3 in the otr happy wash commercials

4 fuel pump? ... why not x2 535 wlbo..& surge tank >fp2000 reg ?

A genuine question, is it engineered and road worthy? Just wondering if you can sell the car later on and the new owner can register it.

but what about the hybrid renesis gsl engines?

Good lord the top inlet on that Koyo radiator is just lazy. Imagine the restriction and turbulence created by that 90 degree bend.

You made it through a full without bitching once!

Being an Rx8 the kit would have to come with a new starter. Open pod in the bay is a bit lazy.

😑🙏 r.i.p. great build ProMaz

What's the total cost?? Looks cheaper to buy an rx7 fd

Rob dahm needs to make Isaiah's rx8 reliable

Would’ve been actually impressed if they actually tried to do something with the renesis

You should experiment with using gslse housings and your rx8 turbo kit to make the build cheaper.

Barra RX8 you say? 🤔

Bridge port is a bad joke so har to tune for power because you have to tune for brap sound

Hahaha "Can't afford an FD? We'll show you how to build a boosted RX8 instead" *Procedes to swap an REW into it and spend more than buying an FD* "Easy as that!"

As if you would put a rotary in it!

would you need a special engineering certificate to make it road legal in nsw?

The cars are nothing but the work is another story especially if you're paying someone to build it. And you won't want to cheap out on the builder, no point in paying for all those parts and effort for the motor or turbo to out on you in a month.
