use the OFNA adjustable motor mounts for the HPI and a dremmel , i used these items a few years ago and i install a novamega big block .15 and it was very fast. But the stock gear diff will not handle that much power ,you will have to run a solid diff as on the impact/835. I got the info from a caraction magazine in the magazine gave you the part number for the wolfpack part number but it also gave you step by step instruction on how to do it with the OFNA notor mounts.It was fun running the car mine was clocked at 72 mph by the Kissimmee Police Dept(Florida) my friend Henry drove it while i borrowed the Kissimmee P.D. Radar gun ( I'm also a Florida state certerfied radar operator and instructor) and got the same reading of 72 mph. Its fun but it is not legal to race. But it was fun to convert it over!
