What engines are direct drop in for the RS4 3 Evo.
I am looking for more power and possibly with a slide carb rather than like the stock rotary carb.
This is my first touring car so I am not sure what would be a direct fit.

Thanks.....RJ
 
hpi pro R xs 1:35 hp 40 000 rpm. rear exhaust.

i got that one in my rs3 ss. very very fast.
rear exhaust so you need the hpi rear header for it.
 
The HPI 18ss will also drop in. That motor is side exhaust, rotary carb.
 
Don't worry about the engine you got a very good stock motor.
enjoy it then move up to a better one. Don't make alot of mistakes that a lot of newbies make by going to the extreme of modding it out
 
yeah, thanks 710 for advice. I am happy with the stock 15 and just wanted to know for futrue reference since I notice the mounting screws for the engine screwed right into the bottom of casing rather than using an engine stand like on my trucks.
Besides, I still need to learn to drive before I bump up.
