Rob I already know that you hate the RX8 and especially the Renesis engine, but as much as I LOVE the FD, I'd really love to see a 20B swapped into a RX8. I'm sure a 13B would be plenty for the RX8 chassis, but a 20B would make it that much better.

[@Kenneth_Rogers]

When I had my RX-8, I was looking to get a 20b and do a bridge port on top of adding a 50 mil turbo. Would have been epic but life happened and I had to go a different direction.

the chassis is smashed up trash, not worth an expensive engine, just put a 13b and a small turbo on it and be done.

@@mikescherrer4923 The chassis and layout is actually arguably better than most other rotaries that have ever come out, the FD is the only comparable one honestly, and even then there are people who prefer the handling of the RX8.

[@chadausburn4832]

I had a similar issue in my race truck’s engine. Oil was contaminated with fuel from previous flooding and I didn’t change it before one of its hardest 3 mile runs. It got super hot and oil started to break down and started coking. Irons looked almost identical to yours and almost all springs were flat.

Recently started watching your channel Rob after another late night looking at rotary articles. Very glad I did cause your content is definitely my favorite rn on KZbin and in general. One of the better if not the best KZbin build series/fabrication channels. Love how in depth you go into the builds and also how you and Isaiah explain everything so we understand. I know that all the filming is likely causing the builds to take much longer than if you guys just focused on the building, similar to the situation with Stanceworks. Just wanted to show my thanks to you, Isaiah, Joel, and the rest of the team for doing what you do. Here for more RX8/Renesis content from Rob and the RX8 Daddy

Replacement bearing in rotor must be staked down or they will spin off. New ones pressed in won't hold as well as OE.

[@splynncryth]

Thanks for the explanation that you guys aren't just blindly shitting on the Renesis motor, that you are aware of how others are building it up, and that the actual biggest issue is that it doesn't make financial sense to mess with the motor.

[@nobodyspecial5026]

you’re more blind than they are he actually blew it up during the previous rebuild, not on the track in general, it’s always the people who don’t have any idea what they’re doing that make the rotary engine look bad. It’s not the engine; Renesis or otherwise. it’s well documented that a properly built NA Renesis will sing out 265-270 bhp, the general issue is that by and large very few people do it properly. No exception here. The only part they got right is that the Renesis costs more, but the drivability you get for the output can’t be matched by the earlier engines. This a proper Renesis engine kzbin.info/www/bejne/q3jYfYN8jq-aic0 .

@@nobodyspecial5026 Rewatch timestamp 28:01-28:06 and 28:27-28:30. Isiah's comments at 28:01 about side plates and hybrid Rensis motors shows he's aware of what others have done. the takeaway is that they are aware of what the motor is capable of. Rob's comments at 28:27 offer a perfectly reasonable explanation why they won't be perusing the Renesis any more. At the end of the day Dahm racing is a business and they need to do what makes financial sense.

Isaiah didn’t port the exhaust for more power he ported it so carbon doesn’t collect there, and then chunk off taking out side seals. A somewhat common problem remedied by smoothing out that area.

Just wanted to say I really enjoy the RX-8 series and especially the engine rebuild videos. I'm never going to own a 4 rotor. It's also increasingly unlikely I'll ever own even a normal FD / FC RX-7. I could own a non-running RX-8 today.

[@BucksSuperStereoWorld]

Also, I am still REALLY loving your yellow Diablo...I have always been very partial to it's predecessor the Countach (especially a 1987 LP5000S Quattrovalvole in red with gold rims, or black with gold rims), but I love ALL Lamborghinis, so I will always have a place in my heart for the Diablo. I've never been able to own one...yet, but someday I will. Like Wayne Campbell from Wayne's World used to say, "it will be mine, oh yes, it will be mine..."

[@aserta]

You don't need to make an adapter. They actually had those kinds of adapters. So look for one online because it's possible you can find it for cheapo. Not likely, but possible. Also, use an extender arm. I don't know if it has some kind of torque lock, if it exceeds X it stops, otherwise it will break your arms, this has happened with old engine starters before.

About the oil, Superfast matt has s600 with a motercycle engine and in long lateral turns his oil pressure dropped and killed the engine becuase it all hanging on 1 side.

The radiator in S1 and S2 are the same. Everything mounts up the same. The fan itself may be a little different, but the radiator and fan shroud didn't change, much, if at all, in the S2 update.
