What's the limit, i still want it to be reliable though.... longevity is key



so far i just went towards the corner seal a bit, I'm using the mazdatrix templates and it's not much larger of a port



Thanks

Theres more casting than youll want to use on the end housings, and the center housing can be ported a good bit, but you really need to start angling the port up when you go more than a few MM up.



Heres more info and pics on the center housing ports.

From what i've seen looks like Judge Ito has joined the two ports together but how safe is it.



Sorry if I seem kinda caution but this is the first time I'm personally building an engine and I don't want it to die because I made the port too large...
