Now lets face it, not everyone can go and drop $500+ dollars on a ported race engine or wants to put a top end kit on a stock tired low end HY engine. So I went and tried a cheap way to make some more power and man did it work! Rovan rc offers 30.5cc complete 4 bolt head high compression long block kits for under $100 ! I already run a Rovan 30.5cc Baja and it seems to move well and is pretty reliable so I figured why not try the same engine in my Rampage XT.
Basically the kit comes with everything you'll need to do the whole job even a flywheel puller tool and a piston stopper tool. It also includes a full gasket set. All your existing HY 30cc components such as your exhaust, clutch housing, flywheel, intake manifold, plastics, and pull starter will all directly swap over to the new 4 bolt engine.
For some of you who are looking just to bolt on an engine and not want to be involved with building the engine, you can get the engine complete for $190 or so including a Walbro WT997 carb and 8,000rpm clutch. However, you will still have to change over the clutch housing because the new complete engine comes with a HPI Baja clutch housing.
Now, my stock HY 30cc engine with the a HPI air filter upgrade, 8k clutch and a Jetpro side mount tuned pipe in my Rampage XT was the same speed and acceleration as a stock Rampage XB with a 8k clutch so to me that was just too slow for me.
Now that I have installed the new Rovan 30.5cc just the first time starting it WOW, what an exhaust tone and loudness difference! After my break in cycle, I then proceeded to race the same Rampage XB that I have raced with the old set up and what a difference! Out of the hole, I leave him, when the engine hits its power band the truck now violently torque steers from the power and screams in the top end leaving my friends Rampage in the dust!
Now I know some of you guys are gonna knock the route I went using a cheap china Rovan 30.5cc engine but I wouldn't even second guess doing it again, I am more than happy with the outcome!
