hey monty i just got back. had a good weekend about to break in the plus 4. what plug do u recomend in the south where its humid. also im checking out the site for a FMS... thanks

just ordered a S21P5XLT and a N21R limited....does the P5 still work well with the same pipes in the past..i think i used to run one in buggy with a 086, thanks

i have 1 fms left .

plug , i would probably use turbo with 97t .

if you wanna use standard , use mccoy mc8 or odonnell 77



happy motorin',

What's FMS

its a plus 21-7 fms (fusion motorsports) a very wicked engine

I hope its wicked as all hell

so fusionmotorsports took the 7 port .21 and modded it?

Jim and Chris spec'd the motor and Novarossi built it.

Supposedly a mix of several different Nova mills with a real bad attitude on the track, just the way I like it.

Ok you'll have to excuse me but who the heck are jim and chris? I'm new but that is pretty general. My neighbor's name is chris.

Nice job! So what is this motor based off of. I just bought the .21 +4. I'm sure they didn't base it off of that.

i would say its across between the toro nero and the older plus 21-7 (both having 7 ports).
monty is the novarossi king and im sure he will chime in.

what if i want to use something else besides a 97t? sometimes they dont lasts long,

Jim Hottinger and Chris Nunez of Fusion Motorsports, the US importer/distributor for Novarossi.

i have had excellent luck in terms of longevity with odonnell plugs , interesting you say that Eric?

i am not a fan of novarossi plugs if you cant tell





dnebout - the 21-7fms is spec'd out by chris nunez (employee of fusion motorsports/novarossi usa) and jim hottinger (owner/importer of fusion motorsports/novarossi usa) i know them both very well and they are very good people .

we learned a while ago what happens when people try to mess with him though (blktransam) , be honest about your engine when it comes to warranty issues and you will get great service , if you aren't , well............................ you won't


FMS is a cross between a p5 and 21-5k in port design 1-horizontal rear main intake , 2-large vertical rear main/transfer ports , 2-horizontal transfer ports , 2- vertical transfer ports and a tri-turbo exhaust = lots o' power

engine also comes with rear main ceramic , highly worked crank with putty filled intake ramp for a more direct throttle response .


the whole engine just works very well at making lots o' power
