RX8 are nice looking cars sadly the bad rotary killed them all, can pick one up for under $1000. Was wondering what all could be put in to swap.k-series would be a interesting mix since it would be a RWD K.
Header is solved for less than $549 it is tight but works for this solution. You will have to run the exhaust back the rest of the way. Coolant passage on the driver's side solved with our intake manifold adapter that has a built in -16AN fitting and we use a back of the head block off plate to channel the Coolant into the adapter. It is on the site now under adaptation-components
I approve of this swap. More power and reliability than that rotary ever had. As much as I love the rotary. The rx2 and rx7 are some of my favorite cars.. but it’s just not worth the time in the rx8 to deal with that high maintenance low power engine… I respect the rotary in the right context, the quad rotor race cars are absolutely stunning. but in a 200hp rx8 with no turbo… it’s just not worth it. Atleast you get a nice platform for your swap in this car. A bigger better looking car than the Miata… but it’s got to be a tight fit for sure.
@@elysiumgaming2866 honestly the stock rx8 engine is dogturd and most of these rx8s will get rotten in a junkyard because of that the Rx 7 13b engine was miles ahead of the renisis.The rx8 is the best car for an engine swap too because there is a lot of blown ones in junkyard
What questions can I answer for you? We have a potential A/C solution that uses the RX8 compressor on the passenger side. Wiring solved using Adaptronic ECU plug-n-play with factory gauges etc. Header solution is under $549. Coolant outlet port on the driver side using our intake manifold adapter/ spacer that has a built in -16AN port and uses a block off plate on the rear of the head. Bump steer correction using extended tappered bolts, spacers and aftermarket outer tierods.
@@TheKevinpenella im actually going to be making some plug n play harnesses to be used with adaptronic ecu. Ive done the 1st harness but will be making about 20 to start
Love the originality not a lot of people out there that can do this kind of work especially create something one-of-a-kind and make it functional but like some of the comments down below AC/Heat would kick ass. I want to k series Turbo a eagle talon in the future.
That was an alternative that we were exploring, another alternative is using the RX8 compressor on the passenger side of the engine and making custom lines.
Header solution is solved just under $549, rear water neck outlet was just released on our site for the K24-A2 head using a -16AN fitting and a block off plate on the rear of the head.
@@CollinsGarage_Crett_Bollins mind I ask what’s total price for the current kit along with the new subframe & s2k intake manifold adapter? Picking up a rx8 definitely wanna grab this kit ASAP
Hey Collins, so, Toyota is coming out with a Three cylinders, all-wheel drive, and 300 hp Toyota GR Corolla Turbo, can we get an adapter plate for that to fit an RX8! Soon as someone crashes one! I'm sure that engine will be the same size as the rotary that's already in it.
This is spot on! +1 on this suggestion for sure. 3 cylinders and the highest specific output engine that Toyota makes right now. Dimensionally this engine would easily fit where a 2-rotor 13B sits.
RX-8’s are cheap mainly because of the reliability of the rotary. I’d buy a cheap one, drive it until the engine went bang then start an engine swap project with it.
Curious about the steering geometry changes as a result of the steering rack conversion/spacer. Was in engineered at all? I know commonly spacing racks willy nilly can mess up the steering, inducing more bump steer, and other funkiness.
Looks like dropping the subframe would make the job easier and then putting it back in with the motor and trans as one big piece. Hard thing is you need a lift to do that
If you have a parts car use the harness from that car, if not buy a harness for your specific engine (if it’s a k24a2 get an a2 harness etc). Aftermarket ecus for Honda engines are plentiful and cheap
Would the ac fit in there if i used some 10mm washers to raise the motor and notched the subframe back in that area? There has to be some kinda way to keep ac lol!
Thicker adapter plate would help, but would simply push everything forward a bunch. The real cutting is only on the cowl section and not on the firewall.
And yet plenty of RX8 owners dont have a problem using various lubrication options it sounds like ....This swap is so daunting (to me) and I would not be driving the wheels off it miles wise (my 20 year old pick up sole vehicle for majority of time has only 80k and my just totalled 2 year old MX5 I had less than 5k miles on that...So I am imaging with a fresh RX8 motor and carefull attention I could likely enjoy it trouble free the rest of my driving life (late 60s now after all) Besides we will all probably be driving insane EVs in 10 years ...when they wind up running circles around IC cars every performance nut and driving enthusiast except for collector types will probably throw in the towel....I mean if the same car will self drive on command AND handle and accelerate like nothing else AND have a 300 mile daily range? How is anything else gonna compete? Other than the sound tract ....which I mean if it important can be synthetically piped trhough the audio of the car! ANY engine sound! LOL
We do have another shop we work with to supplement the other parts that you mentioned. For NA builds we have a swap header for it that works pretty good.
custom harness $1000-$1300 for a good one, good ECU $1500-$1800. all you really need though is the Adaptronic ECU and custom harness to get all of the guages and A/C working etc.
@@laurean5998 i know this would be a lot of extra work, but what about in the back? That and there's cars like the nsx which are awd. Also I hear stories about people putting k series in the back of their cars etc

Haltech elite 1500 ecu works extremely well for this swap. Been running one in my swap for 1yr now. Stock electric steering works,abs,traction control,no dash lights on. Just abit of custom wiring but nothing major.
