My buddy broke his series 4 with too much power.
Series 5 supposed to be stronger in that area

Yes, well, there is actually two kinds of S5 irons. Later model S5 irons are with thicker wall in those areas. They are found from year 91 model. They are similar with FDs.
Really difficult to find tho, cause seller usually dont see and know the differense.
However, earlier model S5 irons are quite strong too, compared to S4s.

Is rear gearing and bearing in it gone? Cause seems to me that this is caused by unbalanced engine

During inspection we cannot find anything else wrong.
The engine ran sweet no issues. On a strong pull and oil pressure dropped and oil squirting everywhere.
I think it's more to do with series 4 irons not liking 400+ hp

Ok, I see. However, usually there is something else wrong too when that happens. Torgue and unbalance of the engine usually causes those dowel areas to fail.
S4 and S5 gearing are shoft shit. They cant handle that power.
I strongly suggest that you get HP Renesis gearings and e shaft. And racing bearings to gears.
Also you should clean and weight how much your rotors weight
All those being said, S4 engine should be good for 400 horses. But it really is on it limits then. And everything inside has to be really good or it will fail

It's not old from its rebuild and port work. done by a reliable and reputable builder.
I think it's bad luck on soft irons. Maybe wound the boost up bit too much, I dunno

These old irons have some casting problems. As seen in mine, there is some "airbubbles" in side.
But you are correct, they cant take big power
But again, and I cant say this enough, sorry about that, check and replace those internals too
Im happy to help if you need, just drop me a message and ask

The picture above is nothing to do with ballance or weak plates, detonation caused what you are seeing.
Good call on the RX-8 Eccentric shaft as its lighter and will fit any 13B engine also I use one in the race cars FD engine.
Hope this helps,

Yeah, and Rennys E shaft has better oil system too. But what really important, is that those gearings are much harder.

My buddy did mention detonation too when we pulled it apart, I couldn't get my head around it due to the continuous rotation opposed to reciprocating pistons. I can't fathom it out, but I don't know sh*t
He said prolly needs a better map to fix

Rorarys hate detonation. Usually rotors takes that hit and causes them to dent. Then they drop compression

Did you manage to find a plate? There's not many around on ebay, in fact I don't think iv seen one at all.
You might be best giving some of the rotary garages a call as they tend hoard parts for collecting dust, decoration and reminiscing

Annnd I can't think of the others

Definitely detonation if you look at the rotor housing in that same area on the Chrome rubbing face that the apex seal runs on you will see where the apex seal has been literally hammering the surface from det. Just above the trailing spark plug hole near where the dowell is located
