Hi guys, just wondering (Probably a silly question), but what parts would you port and polish on the rotary engines?
Also, i am thinking of getting a single turbo conversion, but apparently from other threads there will be work that needs doing to it (Think it may be a US import). How hard it this? is it possible?
I have also got NOS to go in it too, dont worry, i am upgrading the seals to 3mm, but is there anything else that i would need to consider? thanks everyone in advance
Porting and polishing relates to the inlet and exhaust ports in the housings.
Be very careful of importing turbos from USA as they are for left hand cars and our steering rack will be in the way. Not sure what you mean by is it possible?
If your looking at these mods and without sounding rude, as NOS is still not well thought of on rotaries, if you dont tune correctly with your single conversion or NOS you might want to consider these tips.

ah i see, does that mean that if i purchased these:

it would already be done for me and no further porting and polishing could be done?
what i meant by possible was is there some way to convert or make them fit? cheers
No its the actual housings on the engine that are ported not the manifold itself
Its not the ehaust but the hosings, the parts of the engine where the rotors are housed, these can be ported.
The exhaust manifold has not a lot to do with that.
How ever if buying an manifold from abroad, ask if its for a right or left hand drive car, and for what turbo are they made for.
for an explanation of porting see: http://www.mazdarotary.net/porting.htm

a large number of FD owners here have opted for the single turbo conversion, best to do a search here and you\'ll find a wealth of info about it.
brilliant. im a new to the porting and polishing game so did not know what was involved with it. All help that i receive is great, so thanks all for trying to explain it. ive just got to find out if that US single Turbo conversion will need much modifying to fit my RHD :-/ hehe
