does the hpi .15 usually still have alot om compression even though there is a huge hole on the side where the header goes? Just kind of curious. Cause the one that i have, you can turn it over with your fingers pretty easy. Do you think its cheaper to buy a new piston and sleeve. Or jsut buy a new damn motor? Let me know peeps. LAter....

Heck you can buy a motor cheaper than rebuilding it.
May not be the HPI.

Hpi has a motor exchange program like traxxas does. Check it out as it may be the answer you're looking for.

HPI does have an engine that has a carbide coated sleeve, which makes it feel like it has very little pinch. My .12RSS has one. Be sure which engine you have before junking it. Does it run?
Info from HPI site: Our new 12R line of engines uses a high-tech Nickel-Silicon Carbide coating that is being used in many high performance applications by companies like Jaguar. The Nickel bonds to the surface, the silicon lubricates, and the carbide gives extremely long wear. The new Carbide coating in the HPI 12R SS and 12R SC engines, you will see many improvements over standard chrome coatings: 2 to 10 times more durable than chrome 50% higher heat capacity Superior lubrication retention Better for the environment (no mercury is used during manufacturing) |
