I don't think it was ever mentioned on here, but the motor did end up failing. I don't recall how long it was after the car was sold, but I know it has since been rebuilt and had a handful of other things changed more to his liking to go with the GR700 trans.

The motor literally split the e-shaft into two pieces. I've never seen a failure like this on a street car and had always thought that splitting an e-shaft was more of a 1000hp+ drag car type of problem. The only thing I can think that could have caused this at these power levels would be that the oil had thinned out from all of the blow-by and then when sent to super high rpm when hot the front bearing ran dry and and took a shit and locked with the shaft behind hit seeing some serious sauce, causing it to snap, as I expect the shaft itself was super hot too. That would be my best guess....but clearly the engine was making some serious power when whatever happened...happened. I do feel bad it happened after I sold the car, but everyone on here knows it is always a possibility associated with big power rotary. I sent it so hard on our test drive I ripped the teeth off 3rd again, so it was solid at that time.

I'm not sure what all changed on the rebuild outside of a change to a precision 76mm (I think 76), new tuning from somewhere, and it being use as the pathfinder for the new transmission kit. I don't know how much power it ended up making on the new setup, just that it was still in the 700's somewhere.

Ultimately I'm just glad the car went to a badass person who has the means, intellect and capability to keep that thing out there on the road taking names and kicking ass.

Dang, that's the rear side of the e shaft and from what can be seen the bearing surfaces are pretty clean.

This was with the GR700? Possibly the next weak link once the trans was sorted? Wowza

Nah, this was done on the exact setup I sold the car with on another factory trans he installed after we tore 3rd off the day he came to GA to get it.

Definite roping going on for the rear 1/3 of the rear bearing to deposit that much bronze on the shaft. I've only had clients opt for added mains on 3+ rotor setups but hopefully people see the light and start biting the bullet when they want to spin to 10k and make serious power as well on 2 rotors. Looks like you built a great engine.

Hey man, glad to see you are still on here, and still giving out real info the same as you have for years. I actually got this engine from a friend (Ninja Socks on here) who had it in his FD for a short while before he pulled it to go 3 rotor. I'm pretty sure he picked it up from Steve Osley in NC. I think Steve got it in trade from another builder who built it for a customer who backed out on them, and there was some claim of Carlos Lopez having done the machine work, porting and internal bits but there was never any way to verify. When Ninja Socks first got it, it was found to have low compression and Steve pulled it apart to find it had one of those bananas shaped seals from E&J before they became ALS. Steve verified all on the inside looked like mint machine work, put new seals in, and sent it back. When I picked it up, it still made 115-120 psi on all 6 faces.

In a way it was a mystery motor, but at the same time it had everything it was supposed to have and was mysteriously strong as fuck. I never had a single issue out of the motor itself other than it kept making too much sauce and breaking other stuff. Everyone kept low ball guessing my 'street tune' and what it would make on the dyno at 30 psi despite me claiming it would be 700, so when I drove it there on the all-street tune and laid down 711rwhp it was spot on.

Thanks dude, means a lot and I appreciate it. Just building fun things for people, trying to do it for myself at the same time, also have a few products in the works that I'm hoping will translate to not only builds such as these but other markets as well.

Very much a mystery engine. I've had some OK and not so OK interactions with Carlos however when he was on it, he did some very good machine work. Sucks about the seals - to this day I'm still an OEM or ceramics guy unless you're a 12A.
