I wonder how much this part costs.... Star Race Cars Parts Catalog
you can upgrade your renesis with the front cover, pulley spacer, front plate, water pump, and sump tray
.I'm more interested in the water pump and if its upgraded or just modified to fit a bigger pulley for overdrive purposes.....

the water pump assembly is an 86-88 Rx7 unit. they are probably using that because the Rx8 has the water pump and front cover in one casting, and they are using the dry sump front cover which isn't

I read the link OP provided. Thanks, OP.
I find this all interesting, but- and let me stress I'm pretty out of it today, so I may be missing the obvious- how do many of the maintenance procedures, techniques and intervals regarding this dedicated-race rotary have relevance and/or applicability to daily driven, garden variety, consumer owned RX8s?

Most of it doesn't have any direct application. Most of it is simply interesting.
There are a few bits that do apply still, since the engine itself is still pretty similar. Engine management and engine usage is different, as is cooling and lubrication. But there are still things we can use from it. Like the RPM limitations due to housing damage, the fact that Mazda still sees premixing as a good thing, etc...

Don't get too hung up on the oil change times in that PDF, that's normal for pretty much any race vehicle.

Never really seen any particular housing wear or even chatter marks on our racers, but then we make sure we inject plenty of fuel on the overrun (as much for side seal cooling and lubrication as housing wear too).

With the unknowns of the street engines, especially remans, a cautious approach to that is best in my opinion.

do they run pre mixed premix ( VP fuels has it available?)? I think they do.
On the exhaust--they have a nice flowing set up--but iit doesnt look like it is a "tuned". to me. But I know nothing really.
I am curious Philip--injecting at overun doesnt wash the lubrication away? Or do you have a high enought pre mix ratio to compensate for that?
