Project "Bad Ass RX-8" is on...
5 Attachment(s)
After 7 Years It starts tonight!
My son has now became all grown up and got his license. He wants a car, and he doesn't just want any car. He wants to get my 8 back up and running. What father wouldn't want to share something like that with his son - A project that will create memories, bond, and provide experience to the young one that will last forever? So we towed the 8 from where it was stored to my garage and began preparing for the project that we code named "Bad Ass RX-8". This project will include: Complete engine rebuild: Motor will be taken out and disassembled. We will asses the amount of damage and then order the necessary replacement parts. Spark plugs cooling mod applied Street porting Install new clutch Install a set of BHR ignition coils 1000cc Primary injectors Rebuilt the turbo: New turbo manifold and downpipe (Built from scratch as always :smoker: ) Reconfigure intercooler tubing Relocate the battery New HDI-EBC-R Electronic Boost controller 2x 12' fans will be strapped on the intercooler for better charge cooling at low (street) speeds New Exhaust: Haven't decided yet on which one to go with, but it's coming And probably more cool mods as we progress along... Media: (Hurry up subscribe, Like, follow, bookmark and share) :Peace: Project progress will be video documented and videos will be posted onto my youtube channel here: https://www.youtube.com/user/rotorrocks I am also launching a website: http://www.badassrx8.com (Coming Soon) Facebook Page: https://www.facebook.com/badassrx8 Instagram: http://www.instagram.com/badassrx8 Updates: :smoker: Timelapse Videos on YouTube: Day 1 Timelapse: Day 2 Timelapse: Day 3 Timelapse: Day 4 Timelapse: Day 5 Timelapse: Also stuff has been posted on our Instagram :Peace: |

Hey Man look nice !
How much do you think, your project, will cost in total !? |

How much do you think, your project, will cost in total !? Now that we pulled the motor and took it apart i found it to be a huge bust. Rear rotor even though it appears intact has the side seals seized in. Thrust bearings are trashed, so is the pressure plate, bearings are destroyed, I may need to replace the rear housing.. i don't know. I have not done full damage assessment yet but it appears that motor has overheated and seized. but I may need to drop another 1500 if not more on replacement parts. We are taking the time with it. I want to do it right, so there is no rush. |
This is nice. Any chance of getting a better camera for the vlogs?
|
Pretty cool. Not a lot of kids anymore get this level of technical knowledge + bonding!
|
+1 for you there dad.
I agree with fullboost, not many kids these days get any kind of mechanical knowledge or quality time with their parents. Seriously good job. Keep up the good work. Travis |

Travis Appreciate the good words! :yesnod: Sorry for not posting anything in a while. We had a major set back in the build. After the engine was pulled and taken apart, I found that the thrust bearing was completely annihilated and the motor seized. A complete mess. Shavings everywhere, journal bearings destroyed, the thrust flange is literally fused into the shaft and i can't even take it off. :wallbash: Long story short, We had to backstep and wait to put together finance for a replacement motor, which I just ordered from OjImports today. :ylsuper: The engine will be a custom build with street porting and RA apex seals for a little more resistance to a ping. Once it comes in, I will resume the posts and the vlog, so stay tuned! :smoker: |
Oh I'm rather jealous, haha. Hope you two have one heck of a time together with it. :)

Just found your blog. Pretty cool, waiting for more.

Yeah good luck mate.
Just remember you are 1 step closer each day to the finish line.... :) |
Where does this connector gets connected.
For the life of me I can't find where does this thing gets plugged in.
Any suggestions? I've spent half a day trying to find it. :dunno: :wallbash: https://cimg4.ibsrv.net/gimg/www.rx8...e2fde8596.jpeg |
Never mind...
I figured it out. Oxygen sensor which I removed and replaced with aftermarket one of EGT gauge... Waisted all this time :cussing: |
New video is up on youtube

Awesome thread, good for you guys

Your oil line looks very exposed under there .....
What are you doing about oil circulation ? |

What are you doing about oil circulation ? If you mean what I use to extract the oil from the turbo, I use an electrical pump (you can see it installed on the front bumper) that serves the purpose. |
Updates:
Intercooler Ducting and Boost Controller She is alive! |
It may have been only 1 rotor, but it sounded so good. Deep and almost Ducati like.
|
|
I see lot's of boost leaks in your future. Also, the vents on the undertray will probably greatly diminish the efficiency of the cooling system. Oh, and good luck with RA seals.
Other than that, good stuff :) |
I'm kinda confused .............. did you start off with a low mount then change to a top mount . What happened to change your mind on where to mount it ?

Other than that, good stuff :) Unlikely, for the cooling system. There is ducting that I put in that splits and isolates the airflow for the intercooler from the radiator entirely. air for the intercooler flows through and exits through the bottom vents. Air for radiator goes to the radiator only. Yes I heard about RA seals and did quite a bit of reading on them. some say they eat housings, some say they wear faster.. I have also read testimonies from people who have had them for years, running perfectly fine with no reasons to rebuild. who do you believe? I know one thing, first time i had blown the engine the OEM seal tore the housing and damaged the rotor. Second time had nothing to do with the seals, but the thrust bearing failed. I am not going to worry myself with what may or may not happen. Time will show. When you mod your engine to near double it's power output, you can't expect it to run for a 100K miles like the OEM motor would. Hope for it maybe, but lets be realistic. Meanwhile I just wanna have some fun.

Instead of trying to patch it, I opted to eliminating the issue altogether. Plus I had a lot of fun building it all by myself from scratch :rock: Actually took it out for a drive today... The car needs a complete re-tune. Everything is different. Spool is insanely fast. I am getting near 8PSI at 2500 rpm in first gear. All I have to do is open the throttle a little. I was having a real hard time keeping the car out of boost while cruising. A little throttle push and it jumps into positive. I have never seen anything like this on an 8! Can't wait to see how she'll run when tuned properly. :icon_tup: |
Post some pics of your duct work. The more couplers, the more boost leaks. It took a while to get all the local turbo 8's boost leaks sorted. I did it by listening to the experts and ditching the T bolt clamps.
I have known two people with a Renesis who tried RA seals and had issues with housing wear. the only guys who have had good experiences seem to be the RX-7 guys and even those are 50/50. Supposedly they are okay with brand new housings but i wouldn't risk it personally. If you have a solid tune then apex seals is not something to really worry about IMO. Alll the turbo RX8 guys I know of who broke apex seals did it by pushing it with a less than ideal tune. |

Wow .. that's great !Gunna make the car such fun to drive. What size turbo and what AR turbine housing ? |
Spooling that early will get old especially if it comes on fast and sudden. There are also potential long term engine health issues. I know this is up to your personal preference, but I can tell you that I'm going with a significantly larger turbo the second time around.

^ you can put a bead on it easily with your welder :) #madeyourownshiz
looking forward to seeing the outcome. |
Actually my eyes fooled me. it does not hit 8 psi by 2500 rpm. It does spool quicker, but nothing that quick. more like 8 psi by 32 - 3500 which is more along the lines of not so unusual.
I realized that wastegate actuator shaft was pinched in shut position and kept the valve from opening which also contributed to faster initial spool. I corrected that issue. On the other hand the drivers side motor mount popped and leaked out. It is my fault, I forgot to unbolt it and kept on jacking the motor up and down when fitting the downpipe, and pulling on it must have damaged the rubber. :banghead: Now I get to feel all the shuddering and vibrations with my behind. A replacement mount is ordered. |
