Actually any P/S from any Nova based engine will fit (except those from the Novarossi RRL3). Try contacting:

www.fusionmotorsports.com

They carry the TOP line of engines from Novarossi and, seems to have plenty stock of parts.

The part N° you're looking for would be 8608, p/s set 3 ports MCP
and if you wan't it with conrod, would be 8658.

Thanks

Nice site but I'm looking for it a little closer to home ( Europe ).
So when you say nova based I can fit the p/s from a nova mega which is good to get for me.

Ok Herbie, yes you can fit a Novamega P/S set. But if you are, try getting the set from the 2105 or 2106 engines with MCP casting, that way you'll be updating your Mugen.

Hey guys,

I'm looking for a rear engine cover for a Nova Rossi RS12, the one with the cut-out for the piston (RB X12, Top, Rex will also work)

Please let me know if you got one you want to sell.

Thx

Thanks afm did search the internet this afternoon and found some different options to replace the p/s.

Ran my new mr12 in yesterday in my 710 but I enjoyed the easyness of driving the kit. The engine ran to hot so I think the p/s is allmost worn already

what are the differences in the rex, top, and novarossi motors?
it seems the only motors out that are good are nova made?
I have a $250 motor budget, which is steering me towards a sirio. every one i run with has a nova or sirio, i looked at the rex and top ones but aren't they novas?

NovaRossi makes the following; NovaRossi, Rex, and Top and I don't know what else. If you go to the Nova web site if you look at the same motor within each brand name the parts in the motors have the same numbers. I would say any differences between the brands would be very subtle if any.

The novarossi brands are Novarossi, Rex, and Top

Nova based motors, which means novarossi makes the motors to the specific companys specs, are RB and Mugen (there may be others that I'm not remembering)

If you want to get a good nova based motor within the $250 budget you have set, try the RB V12 3 or 5 port. They may not have the top end of a NS based motor but they are very driveable with the power to keep up with the NS based motors.

Find Novarossi RR12L3(stock), guarantee will not let you down.

You are right, Novarossi brands are Novarossi, Rex, and Top

Nova based motors, which means novarossi makes the motors to specific specs, are RB Concept, Mugen, Novamax, Novamega, and JP.

The importer for TOP is Fusion Motorsports
The importer for REX is RJV Racing Products
The importer for Novarossi, Mugen and JP is Mugen Racing
The importer for RB Concept is Sigma Trading
The importer for Novamax is Calandra Racing

I understand that Fusion Motorsports has ordered a special spec version of the TSR12 S3, which makes it a bit different than the Novarossi NSR12 S3.

Anyone knows where to get a turbo head button that will fit a 3-port NS12? Thanks.

what is the difference between all the novarossi 5 port motors???

You mean between Novarossi, Top, and Rex.......... as someone said "very subtle if any"

AFM

no the t5, the s5 the s5 race and t5 race to name a few i think there are more also, just being curious.

JUST DIFFERENT EVOLUTIONS OF THE SAME MOTOR I THINK IN THE FOLLOWING ORDER
RS12T5 R1, S1
RST5 R2, S2
NS12S5
NSR12 S5
