Are theses engines worth building currently have a 04 4port auto that’s ready for a rebuild but I have a few options I’m considering and I’ve noticed there’s a pretty big torque difference between 4ports & 6ports also could I hybrid build or pp a 4port ? From my understanding 4ports handle boost better as well

Also most people that turbo a 6 port leave the additional ports open due to tuning difficulty. So that additional torque gain is usually due to this. Suggest you hop on over to the turbo build threads. Loads of information there to get you up to speed one what it would all entail.

I was going if a kmr video of him porting a 4 port and he had mentioned applications in a peripheral port build is why I ask that question basically is there any gain in adding the additional exhaust ports even tho your lacking the additional two intake ports

Torque will come on sooner with a 4 port vs a 6 port due to less intake flow but higher velocity, not necessarily more. (Someone can correct me if I am wrong here)

Quick and dirty answer; NO. Low end power is gone, and the upper rpm does not benefit from the additional exhaust flow volume. AKA the exhaust ports are not the restriction everything thinks they are for the renesis. At least not until high HP applications. Hell Landspeed was able to achieve 600whp+ with the renesis, this was a completely unstreetable setup though, probably not even road course-able as well.

Now this is with the automatic 4 speed transmission.... but this pretty much shows you how gutless the 4 port will be compared to a 6 port. Video is mine of my original Rx8, and I had every single bolt on imaginable (minus turbo or supercharger, no nitrous, but basically every available bolt on) and still only made 150 wheel hp at 7,300 rpm and 124 ft-lb wheel torque at 4,900 rpm.

Otherwise where are the dynos from him or his customers showing anything better than stock power levels? There aren’t any, and for good reason.
wake up and start educating yourself; not intended as a slam or condescension, it’s just the cold, hard truth. but men love darkness (lies) more than the light (truth), because they either can’t bear the painful reality of it or their pride, vanity, and arrogance keeps them from accepting it. There’s no shortage of it on here no different than everywhere else.
