Are they that much more expensive? What about the carbon over stock? Is it worth beefing them up at all during a rebuild, even if it is just a daily driver occasional road racer.

well they require machining of the rotors...so that can add to the cost of going with 3mm 's..but if you are out of spec for 2mm's..then it can SAVE you money...they stand up SLIGHTY better to detonation...but not much more...the rotary must be tuned well...regardless

customimport ???what does that mean...
yes carbon is expensive...if I was to get new seals I'd go for those ones from Hurley...they great thing about those is that they can be softer...so if one get shot...it's less likely to take your housings with it...housings are expensive....

Don't get stock. Just get the Hurley Racing seals. They are the best bang for the buck. The 3mm's are the same price as the 2mm's...bout $350-400, but to grind the rotor's to 3mm is about another $300.

Nothing johnny, just took a chance. Thought you might be someone I know, through the 'net.
Thanks ernieT. Just curious because I'm sure I'll be faced with that decision one day. Hopefully a long long time from now. If I can get my ECU, that is.

Blow up or win
Machining the rotors is really tricky stuff. If they are not done perfectly for the 3 mm - kaboom! My personal opinion is that they are extremely hard to do, even for a skilled operator. I would opt for new rotors and stick with 2mm, even though they are outrageously expensive. Clearance is everything on a rotary. Very few FD3S rebuilds require new rotors though......

2mm makes more power than 3mm, It is to do with better sealing and reduced friction losses.
Take two identical engines side by side and you will see a power increase in the 2mm apex engine v's the 3mm one....it makes sence when you think about it.
