Yeah the mspeeds are nice but surprizingly not that much cheaper. about 10000yen cheaper but not that much really. I have many friends that have used mspeeds, and while they like them they have all converted to novarossi based engines and say there is no comparison. also the idm have the new red dot crank and microcast piston. So i thought id try it out.

here is some info for those of you that wan it (from idm manual)
this is the 3 port info

displacement- 2.1
power- 1.54hp
rpm- 41000
stroke-14.04
bore-13.8
sleeve-abc
ports-3
crank- modified red dot crank
piston-microcasted
case- new idm case

This engine has insane compression and a wicked pinch! I got it stuck a bunch before actually getting it to run so make sure you heat it up loosen the plug and have fully charged batteries and youll be ok. It was all i could do to free it up by hand with the engine pulled. Just dont let it stall on the first couple of tanks and youll be fine. I cant wait to fully breakin this engine as already it sounds beautiful! patience.
