will it fit
 

hey will a 4.6 big block fit into a rs4 3? if not what motor should i get with some what that power? of should stay with the 15fe i got

omg people (no offense) but why do you think a bigger engine means ti will go faster, no it wont fit without custom mods and no it wont make it go faster, gearing is what truly determines speed aside from the engine, if you have the 15fe and want mroe power, then get the os 18cv-rx, thats like almost 3 times the power of the 15fe, and its only $110

ok will it to go faster than a savage 4.6

RE: will it fit
 

it depends on the gearing, just because it has a 4.6 doesnt mean the speed will stay the same, just get an 18cv-rx and gear it up

the os .18cvr is a monster i run it in my rush and its insane. im going back to the track with it this weekend and if i cant control the truck this time im swapping the engines between the rush and rs4-2 (fresh rebuilt torq.16) i think you could gear the os way up

I cant agree with you more apollo. I finally got my .18ss broken in and tuned just right. Its got a smooth idle and gobs of tourque. Needless to say its got pleanty of top end. All of this with the stock .18ss the kit comes with.

A bigger more expensive engine isnt always better. Do your research and learn how to put a good tune on a motor before you go spending your money on a bigger engine. (No offense here as well) I just hate seeing people dump $200 to $300 dollars on a bigger engine then getting smoked by a smaller one that someone spent there time tuning it and gearing it properly...just my 2¢. Would hate for this to happen to you nitro-man. Just watching out.
