OS .18 TZ vs .18 TM

[jpsonoma]

Does anyone know what the difference between the os .18 tz and os .18 tm is? the tm claims 1.6 hp and the tz has like 1.8. Is the tz the same internaly? Except it uses a turbo head instead of the standard like in the tm? Is that the only difference? and if so can you buy the turbo head button seperate? The reason i ask is because i want the tz but it doesn't come with a pilot shaft and a recoil, the only recoil version is with a threaded shaft, but the tm you can use a recoil from a trx 2.5 and it has a pilot shaft. Anyone have any info? thanks

aucutually i think they were braggin that the TZ broke the 2hp barrier...

i just dropped the TM in my revo, and if its just the head, then bring it on!

Yeah, the TZ was dynoed at somewhere around 2.2 HP. Insane.

Your right, i think rc car action dynoed it at over 2hp, but os only claims 1.8. they seem to under shoot there horespower ratings rather than over like most companys do. Thats why i want that engine it has some serious power. But anyways, has anyone found out if it is just a head or is there more to it?

the TZ is 5-port and the TM is 3-port. and the crank timing may also be different.
