I was in my lhs and he has the NovaMega 12XS SS engine. He said it's the same as an NS12 but costs less. Is that correct?

Yes, just like the RB V12

How much is he asking?

$220 for the 3 port and $230 for the 5 port. Is it worth it? So you're saying the V12 also uses the same crank and piston and sleeve that the NS12 does?

Also, does anyone know the sizes for the NS12 bearings or if anyone makes ceramic or heavy duty bearings for this engine?

Thanks

Boca Bearings have the 11.5x21x5 and 7x17x5 bearings in ceramic.

yes it is the same.

ok just got my ntc3 and am wanting to get a ns12s3 or ns12s5. What do you guys have to say about these motors??

Will any Novarossi .12 conrod fit? I saw that www.rc-mushroom.com has a conrod that says its for all .12 engines. Is this correct?

Yes it will fit an RS12

Just make sure, the part number was :
NRS-07601 COMPETITION CONROD

it will fit all Nova .12 engine except the new RR

Great engines....easy to tune, long lasting, fast

NS12S5, can't go wrong w/ that. I just finished breakin it in and its sooooo fast!!!!

sweet sounds good to me

Rod the only thing the two have in common is the diameter of the crank and the rod. The profile of the NS crank and the V12 are significantly different. The NS also has the billet piston,and corkbond finished liner and the V12 does not. The parts will intermix but they are definatly different in the area of performance.

DR, I thought the NSR was the one that using billet material instead NS is it ?

funny you ask that because I am slightly miffed at novarossi's current lettering system, I thought the R was a rotary carb version but I could be wrong. However I think I can saftly say that if it is an NS version it has the billet piston. I used to have a very good handle on it all but its gettin a little fuzzy now that i'm not into new customer motors every day.

Oddly enouth the NS's we get here are marked
NS12S3-A1
