4.6cc nitro engine..
 

Guys, i have a question..

can i put a 4.6cc nitro engine on my HPI nitro 1/8scale on-road??..

cause it has a 3.5cc nitro engine now and im thinking that if the 4.6cc will fit??.

can it really fit??..:)

Bigger isn't faster......

The 4.6cc has the same size housing and mounting so it must fit.

so 3.5cc is much better than putting 4.6cc??..

The .28 engines are made for monstertrucks. A lot of torque but no top rpm. If you can find optional gears you can get something out of it but an 1/8 onroad racer its gears is based on high rpm engines.

3.5cc from Force.. No.
3.5cc from Novarossi/Picco/Sirio... Yes....

oh now i get it..you dont need that much big engine for speed..thx a lot!!

its a 3.5cc engine from HPI..all original :D

Is it this one?:

That is a Novarossi based engine and you can fit a new P/S set from a RX21 or 321

it look like that..but it got a bigger block..a violet one

and i just loved it..:nod:

and another question is 3.5cc and 4.6cc the same size but different in weight?..cause in the web the 3.5cc engine got only specifications on it..:confused:

As I mentioned before

ok thanks alot..:nod:

but can i put it on a NITRO TC3?

It is no direct fit, a TC3 needs a smallblock engine but if you are handy you can fit an 3.5cc into a TC3
