Overhauling an old engine
 

Just acquired an old Novamega sx-21 7p-ev2 motor. I'd like info on overhauling it with new internals. Thanks.

just Got the mugen mt12, long head. Has anyone tried to fit the turbo head on this engine?
thanjks

Hey afm,

I haven't forgotten about you on updating the x12. I have had 2 rain outs the last 2 weeks hopefully next weekend we get some sun.

Hi , where do you guys get parts for novarossi engines ? i am looking to buy new bearings for my MR12 and also do you know if bearings size are the same for a NS12 5 port ?

After changing from a .15 manifold to a .12, smoke and fuel are coming up the lid of my tank, seems like there is too much pressure?? i have tryed longer pressure tube, but no better.

My tank isnt that old, 6 months?

Any suggestions??

where did u get your x12 and what are its specs?

I got it from here http://murnanmodified.360k.com/

* Displacement: .12 cu in (2.1cc)
*Horsepower~1.52 HP @ 41,000 RPM
*RPM~ From approx 4000~43,500
*Stroke~14mm
*Bore~13.8mm
*Ports~3 port
*Shaft~11.5mm

The motor he sales is modified, shoot him a email maybe he can get you more info.

Well finally after two weeks of rain outs we where able to race today. I ran my Murnan X12 and it was fast I was truley impressed. I still have a little tweeking to do and I think I can get more out of it I was able to drop my lap time by 1 second. I didn't have one single problem with it. I would say this is a must have engine.

I have a Nova Rossi P5 .21 and I can't locate a "Nova Rossi" piston and sleeve (Thanks Ernie :flaming: ) but I have quick access to RB parts here in Canada via CG Royal....what RB piston and sleeve would be the same if at all ?

Hey Number 11 I would love to get one of those Murnan Motors but he hasn't answered the emails I sent him like 2 weeks ago.:)

Yeah he is a little hard to get a hold of. The chassis is the Audi R8.

hi,
What is the difference between a MR12 and a MT12??
any differences in performance:confused:

specs of novarossi MT12 front bearing, anyone?
 

Hey all I was wondering if anyone knew of a place where I can find out the specs of the front bearing for the novarossi Mt12, besides the manual; which I do not have.

thanks all-Jason.

NSR12 / Top TSR12
 

Can someone tell me the factory settings for the carb on these engines.

I have heard 4.5 HSN and 2.5 LSN
...and...
4.5 HSN and 3.5 LSN

The documentation doesn't say.

Re: NSR12 / Top TSR12
 

4.5 HSN and 3.5 LSN is what I always start out with. I have never had a problem with that setting and adjust 1/8 to a 1/4 of a turn from there.
