Hi there to all you rotary fans out there,I am new to the forum but not to rotaries and thought you might like to hear that you can do things to side housings such as having them lapped(removal of material ) as long as it is fairly minimal,ie about the wear that you have in an FD engine when it needs rebuilding lets say 50,000 miles or so. Also nitrided housings have been used by Mazda way before the FD in other rx7s.If you talk to Racing Beat they always lap their housings.;)
As regards porting side housings there are many routes you can take and much depends on what model of car you have and what you want to acheive but if you have any porting done then the whole package must also be looked at too so the they all work together for best result.
Exhaust porting can be done on almost any engine, and benefits will be seen as long as the exhaust is also upgraded, of couse the down side is that noise usually goes up and especially on non turbo cars,so once again you need to make sure that the wholepackage works together.
If you are contemplating racing then the parameters change a whole lot more as you may or not be permitted to alter your ports.
Hope that this is of interest to someone
