Hows it going guys? This thread is amazing tons of amazong info. I got a used mito4 off eaby for 150 bucks an it came with the 9901/41021 combo as well. I must say this engine is very strong an just runs amazing an holds a tune very good. Im running it in my mugen mbx5R an she just flys you hit the trigger the power is right there right now . Im a bit nervous about this engine after reading about them failing.

This is my 1st high end engine an im very impressed. My engine came with the nova fuel cooler as well what do you guys think ? Dose it work or snake oil?

Im running the nova clutch as well with the nova 14 tooth clutch bell. Im super impressed with this combo works super good lays the power down very good.
