In your video I see a lot of parts. By chance are you able to or willing to send an engine ether complete or a complete engine to build to a friend of mine who Is trying to build his car. He used to have one along time ago now he has a body and some parts. I would like to see him be able to get back in one again but just the body will eat up money and parts and time, a really good price maybe or in a rear chance a gift, donation, or right off. I started him a go find me page. Willard Davis. But I don't know how it works really. He doesn't know I'm asking or doing a go fund me page. But I'm trying to help him where I can.
This video was posted 7 years ago and you probably won’t see this comment but I just have to say I’ve been watching your engine build videos over the years and they were always top notch but I had no idea the absolute amazing fabrication skills you possessed! Freaking excellent job man I’m blown away I’m going to watch this video a few more times over the weekend. I am super impressed!
Why don’t you leave the apex seals in the rotors on assembly and then just pull the corner seals out with a magnet and then slide the springs in, and or pull apex seal out and put the springs in like the way you do it? This eliminates any corner seal miss alignment. I know you slide an old apex seal in to align the corner seals but there is a chance they can move when you put the rotor down, especially if you move it. Then you will have to remove the rotor and start over.
maybe you have done this by now but why don't you have the studs made with allen key in the back end so that you can just use allen wrench to screw the studs down? Allen or torx......
Off topic but those jeans go hard! What is the best intake set up for a gsl se motor? Originally I thought some 12a irons, 4 port intake and along with a healthy amount of porting. With the lack of availability on 12a irons I’m starting to wonder if a couple racing beat p-port housings would about as economical plus part availability. Just looking for direction in my build, anybody with experience on could chime in, I’d appreciate it
These guys lapped my irons for my rx8 engine and they ended up totally chewing through my oil control and scraper rings. Lapped right through the nitriding too, so I went from zero step wear to out of tolerance in only 4k miles. Super disappointed
Studs should’ve been standard equipment on rotary engines from the Mazda. You guys should have the manufacturer of your studs make a hex at one end of the stud to help with installation.
My profession is completely different. However, when it comes to custom work and the satisfaction of making things fit and work together just right, I definitely know that feeling.
so has anyone tried making an "opposed rotor"? two housings side by side into a common chamber? i guess the mercedes thing came sort of close. but nowhere near it. *has mental image of five rotaries strapped together in a ring with bevel gearboxes*
Man i wish you werent all the way in canada. Im about to pull my rx8 engine with blown coolant seals and i really dont know if i wanna undertake the rebuild myself.
it doesn’t really matter given all the potential efficiency losses created by 5 exhaust ports from 2 rotors with mismatched opening and closing times. There’s absolutely no way to build proper NA manifold that can effectively pulse scavenge tune this configuration. If you really understand how an engine maximizes torque, from which power is derived relative to rpm, then you also understand why there’s never yet been a single NA hybrid Renesis to date that ever came close to the output of the best built stock port Renesis engines. if you want to see a real blueprinted and properly built stock port Renesis engine runs (as supplied by Daryl Drummond) then search youtube for a video titled “Dan Wheldon Star Mazda Test at Indy”. .
You can just see it on the housing as he picks it up. You put the sealant on which ever has the o rings as they will indicate how far to apply the sealant. 27:20 you can see it all
I’ve been waiting to see you guys build a hybrid… great work👏 I want to build a hybrid for my 8 and thankfully you guys build them… only thing holding me back is where to get a custom header to accept the 2 additional exhaust ports. Please if you all have any recommendations, drop me a line. On a different note, great video & great information as always… I am a huge fan & looking forward to having RX7 Specialties build my hybrid.
Adam and the team was phenomenal with keeping in touch and keeping updates as they went through the build. I have one of Kyle Mohans flanges that I will be working with in the future with a custom fabricator but the header will be something I battle after I get the engine back. Overall I couldn't be happier with the build, and just take your time researching before you pull the trigger.
Thank you for that info, I’ve been doing a ton of research on this subject matter but it seems like everything stalls when I try to look into the exhaust manifold. I have always owned a rotary going way back to the FB’s… I love my 8 but Mazda had a brain fart designing the Renesis. I have seen Kyle’s videos as well as there is a lot of data out there based on the build. I hope that you enjoy your hybrid, I will definitely be taking that plunge very, very soon. Thanks again for your reply 👊
you are wrong about the factory front thread sizes. there are cars here in australia making a lot of hp running fast Ets using them. you are going to crack plates regardless of studs, its all to do with the tune, and if you are still cracking plates, you need to get billet plates once you are in that hp zone.
