New engine decision help
 
thinking of upgrading my 3.5 trophy to a better .21 motor like a novarassi or similar that makes about 2.7 or so hp . Will it be ok to do the swap and will I the stock differential and all gears be able to handle the swap? Thanks

So if I put that motor in will I need to change any gearing? Like the differential gearing or can I leave it all stock and it’ll hold up ???

3.5 trophy like the first post says . Will a new motor like a Novarossi work with the stock gears and differential? That’s my main question

Most likely not a problem as I believe HPI uses Hotbodies parts for things like diff case etc, though it seems like there is some options for upgrading the drive train...
But I would go for a new clutch, it will give you the ability to fine tune the clutch and that might be needed when you change the engine from stock.

That car comes with a pull start engine, you may need new engine mount and a starter box to use a race engine / non pull start engine
