How much but!?
It's a full package not a cheap package. 👍
@@chrisecob729 My guess is 40K+
@@bigbanana4111 approx $50k was my quote
I'm on a firefighter wage, can't afford that unfortunately
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.
When were they ever 60 grand? LOL the MSRP was less than 35K and that was towards the end of their runs. Dealer mark-ups for more than 10K just weren't a thing back then.
@@Lunch-b0x consider that maybe he lives in another country w/ diff currency and diff availability -_-
What a perfect tribute and a way to keep the memories alive of his brother
Miss working around the corner from these fellas
Hearing doritos brings a smile to everyone
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
They are garbage. There’s a reason why Mazda is the ONLY manufacturer that produced them.
100%
I want to own at least one rotary sportscar at some point.
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 .. 👍
Simon 🤠
@@fullboost thanks guys.. Typo fixed! 👍😁
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.
one day I'm going to have to ask for some work experience with this man, great workmanship and great to deal with!
Even better when there's a good story behind the car
Such a cool and special build, always love seeing some rotary content.
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.
I wonder how tits sound 😂😂😂
Top video! Luv listening to Simon talk Rotaries
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
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
Wow 😲 this video is an amazing find. Loved to see the mods for the RX-8
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 🤔
In the us glse hybrid builds are a bit popular for a hybrid rx8 build
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 to make a great looking $3500 car run good with $25-30k in parts lmao!
Exactly..this is a big dollar engine conversion
Still cheaper than buying an FC then
Yep - Or you could spend 30k on an older car and spend another 30k to make it fast. 👍
@fullboost youre not wrong lol. I wish promaz would make an entire kit that comes with literally everything needed for the swap for us in America like they have for you guys down there.
@@em2attic why don't you k swap 1 instead
Full boost working with only the best!
awesome video
Now that's a proper build RX-8.
How good is that! Got me hooked! I've reached out to Simon already.
Love the sound of these Fd's 😎😎✌✌👌👌👍👍
My next move on mine 😊 sell my running renesis to help fund the conversion. And it’s black 👌
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.
Awesome 🍻
Greetings from Greece!!
Could watch the "Rotary Yoda" all day fella is a picture of carmness & knowage. More of this pls.. 😎😎✌✌👌👌👍👍 frm the UK 😆

Great video. Great car. Great guys.
Thanks! 👍
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.
Wasn't god who gave the bloke brain cancer in the first place?
Simon is truly legend❤
I have RX-8 spirit R and im looking for this project 😅
Best in the business !
Promaz is a dreamy place
Nice Tribute Car for the Memory of Tim🙏
8:34 Thats a 90's 626 at the background.. you just dont see those anymore these days.. all must been crushed away
Hopefully it's getting a conversion. The engines in them were pieces of crap.
@@bangkokstallion Yeah I remember those having alot of problems and rust was quite bad issue too.
@@bangkokstallion Woah hold your horses! The F2T 2.2 Turbo is mighty capable of decent power. If you've ever driven a 626 turbo/Telstar TX5 turbo or a MX-6 turbo you'll know how fun it is getting on boost and fighting torque steer. I have the F2T in my car with 235,000 km's on the clock 35 years old, doesn't use a drop of oil.
They're around. People asking too much for them though.
@CRF1000L Aus exactly mate, F2T in my MX-6 Turbo was a beast and it went strong for near 300,000km.
Is this possible on a series 2 rx8? There seems to be issues finding an ecu that is compatible
how do you go with passing ADR's putting an older emission spec engine in a newer car in Aus?
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
Good God, what i wouldn't give to have my RX-8 in that position. Someday, Mozzie, we'll kick some Time Attack butt
This is the right way
I'm looking for the left way
nice video, rx8s are definitely getting cheap now
Big fan of promaz
I love Mazda Rx8 .... like i realy like them
That early RX-7 though 👀
*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.
good swap, should have come like this from factory
Gonna go boom boom
Nice build. Surely 13B motors are rare as hen's teeth by now?
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.
you are so much in the wrong about everything, i can't even begin to say something
Okay so a renesis is unable to achieve 9000 rpm, Bridgeport's are smooth and provide acceleration from the start, streetports are no good down low and only good at high rpm. Superchargers dont work at low rpm and have even torque from start to end. I am dumb fucker.
There are benefits to a hybrid build for sure. But I'm not sure what the best combination is for exhaust ports. If you can block sideport exhaust that would be best. I think super charging one would be awesome man. Don't give up
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 !
Try 50k
I got a quote today and it was a smidge under $60k 😱
crazy init, and we know how much actual parts are. Worst part is basically no warranty om aftermarket modified motor builds lol
@@user-hb3ib5ms8m
about 15 yrs ago i had a monster bridge 12a from them. Mate had all done. 8k
i bought car and i think between us we had few nights fun here and there and got about 3000klms between us lol
Replaced 2 more after that ;(
Do you guys sell kits
I was looking into grabbing a set of the ignition coils seen here -- too bad they’re about $1k :///
damn I want one
is it cheaper to add lightness?
Is this able to be engineered given the engines are older than the chassis generally?
I doubt it's registered to the chassis
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
I have RX-8 can you say what radiator/intercooler used?
Does this come in a kit?
Does this still run a dead head fuel system?
What does a setup like this cost?
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.
In Australia? They aren't boost friendly, so reliability comes.into question.
is this sold as a kit that can be shipped to europe?
if every Rx 8 could talk like the mazda 3 in the otr happy wash commercials
Good lord the top inlet on that Koyo radiator is just lazy. Imagine the restriction and turbulence created by that 90 degree bend.
Hi does anyone know how much for the kits I have Fd engine already 😊
When are u going to moontune the new WRX u bought??
Still got the hutch Simon?
Being an Rx8 the kit would have to come with a new starter. Open pod in the bay is a bit lazy.
Not sure if you know how intercoolers work.
@@juslookinatyas With that reply everyone here knows for certain that you have absolutely no idea Shauny.
While i agree, there is no need to accuse them of being lazy
@@jarrod1687 i didn't say they were lazy i said it's a bit lazy. I'm sure the owner would have been given the option.
While it's not going to hinder performance significantly it could always be changed later on if it bothered the owner.
Does the renesis turbo kit work with an S2 renesis?
They also do a Renesis kit, it was discussed in the video.
Yes, and with e30 you'll get around 400hp too
😑🙏 r.i.p. great build ProMaz
Is this a kit You can purchase through this Company?
shop.promaz.com.au/category-s/114.htm
Can’t find it on your site, how much for the RX 8 kit featured?
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!"
Yes but this car will shit all over a std FD ☺️👍
Great video. Would hope they would include the cost of the build..I'm guessing not much change from $18-20k..
To build an engine and swap it in with all the adapters, fabrication, and custom work? You must be joking. I'd be surprised at how cheap it would be at double that.
Good luck doing it for that budget. ☺️👍
Probably more than twice that, all the hours and parts....
@Fullboost Do you know the ballpark cost of doing an exact build like this? Thank you
@@sonny.888 at least 40k
RX8 is my dream car, i would love to own this car if i have money.
Barra RX8 you say? 🤔
Lead-tipped arrow.
@@ChristopherHallett don't know nothing about arrows or if it's a saying I've never heard it. Is that good or bad?
@@davidt3196 How do you reckon an arrow would perform if you hung a big lead weight off the front of it?
The Barra is so long that most of the engine's weight will be forward of the front axle line, which significantly changes the fore-aft weight balance of the car for the worse.
Why buy a sports car and then make it significantly less sporty?
Rob dahm needs to make Isaiah's rx8 reliable
You guys don't do anything in the United States, right?
Where are you guys located?
Melbourne.
A noob question, is the rotary run in process the same as a piston engine or different?
Same same. Drive it like you stole it.
@@piffiiiiiiit Yep! Don't baby it, get it nice and hot and work it hard. You want to seat those rings (or in the case of a rotary, the seals) properly!
What’s the legit conversion cost?
but what about the hybrid renesis gsl engines?
They're not as good as an FD/Cosmo.
@@fullboost yea they aren't as good performance wise but for budgetary builds they seem to win out due to not needing to massively modify the engine bay and needing a little amount of custom mods for the process to work, It can be looked at as a nice inbetween for a stock renesis and full 13-b REW swap
Yes depends on the budget agreed.
Felix Wankel was a great man.
besides I bought a Mazda RX8 for $1,000 and drove it home runs great 106000 miles it was just flooded needed some solenoids
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.
I doubt old mate would spend all that time and money on research and development for something that's unroadworthy.
afaik the screamer would need to be plumbed back into the exhaust if you want to get it engineered. Other than that no way all that r&d wouldnt allow you to re-register it.
afaik, you cannot engineer this car as the engine is older than the one its replacing, thus it has different (worse) emissions standards.
No one cares though. Its 100 times better than the renesis. The next person that would buy a car like this is already playing the same game with legalities. Modified cars 101
@@nismofreak33 you can’t get the rego transferred, so in effect once it changes hands or you get pulled over it becomes a 60k track car only
@@lengerer Bullshit. It's not what you know it's WHO you know. Victoria where Simon is based u can transfer rego, of course you can, but OK I can't speak for every other state.
Bridge port is a bad joke so har to tune for power because you have to tune for brap sound
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.
jeez, my buddy got his rotors cut for rx7 seals and then slapped a turbo kit on there for $3k, makes around 350hp
Is he still running? I considered this for mine, but engine would have to be rebuilt before hand.
What's the total cost?? Looks cheaper to buy an rx7 fd
Yes it's a full conversion not a cheap conversion. Yes, but you'd still have a std FD. These are a popular conversion. 👍
You should experiment with using gslse housings and your rx8 turbo kit to make the build cheaper.
would you need a special engineering certificate to make it road legal in nsw?
I really want to get a rx8 with the shitty motor that it comes with because nobody want to deal with it and im sure you can really do something with it but.... So many problems its discouraging... Ima do it tho
Good luck. ☺️👍
@@fullboost I'll be sure to tagg you in it
The cost to do this...
Youre better off just buying an fd I assure you.
A cool swap, but I think most people would be shocked if they saw the bill...
Have you looked at the price of an FD recently?
@@ChristopherHallett yeh, 50 k will get you in one...
What do you think this conversion costed lol?
But then the FD is stock still? Quite different cars.
@@fullboost tell them what this car costed and I'm sure opinions on it would change very fast.
Rx8 is a much more comfortable car that's for sure..
@@snakepliskin2297 Including the RX-8, probably about the same. Except you get a roomier, more comfortable car that's at least a decade younger, and it makes more than double the power of a stock FD already.
As if you would put a rotary in it!
You made it through a full without bitching once!
We'll make up for it next time. ☺️😬
