hi, i would like to know if a nsr12s5 and the n12ls5 have the same piston and sleeve? nsr parts are out of stock and still want to keep it running.

thanks

NSR12S5 piston/sleeve/rod set are in stock.

If they have the same bore and stroke, I would give it a try. I think LS version has better porting than older NSR.

yeah, same bore an stroke.. port design,im not so sure if its similar.

Hey there,
I just bought a Truggy that came with a Nova 528X, It has a P3 plug in it.
Im looking for what pipe to run with it. I plan to race this at tracks in AZ like the Nitro Pit and othere like it.

Nope, won't fit. The LS engines have the taller sleeve / case which does not fit into the old NS / NSR cases.

I just got a new Plus 12-SCT 3 port Murnan modified engine... What do you guys suggest I use as a breaking method for this engine??? Can anyone shed some light between the difference between the 12-CT and the 12-SCT???

The SCT has a bigger bore shaft (11.9). I think the CT only has 11.5.

CT = 11.5mm
SCT= 11.9mm

Thanks Sam
I'm gonna edit my post (can't believe I missed 1mm )

That is what you get for not running your Nitro Touring Car that Often.

Yeah tell me about it. I'm having sedan withdrawals . It's been a little over 2 months already that we didn't have a sedan race here in AZ. Good news is, our racing will be back to normal schedule starting this Friday .

By the way do you stock Novarossi parts?? (i.e. bearings, connecting rods, etc.)

I just came from the Argentina WC 2007 and the track support from NOVAROSSI was great!!!!
They repair and or check the engines.

GREAT SUPPORT!!!!!!!!

Keep up the great work

Of Course!
