Building a Mazda RX-8 the right way | fullBOOST

[@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 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.

[@Lunch-b0x]

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.

[@aj_art8058]

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 🤔

[@jhon-cg4rg]

In the us glse hybrid builds are a bit popular for a hybrid rx8 build

[@Flyingdutchy33]

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

[@MrRotaryrockets]

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

[@constantinelheman]

Now that's a proper build RX-8.

[@chilrl7425]

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

[@ADudesRotary]

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.

[@1cipi]

you are so much in the wrong about everything, i can't even begin to say something

[@ADudesRotary]

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.

[@jasonskinner1652]

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

[@dr_tal]

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.

[@MasonV1]

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.
