I just got messaged that a guy bought an os 18tz from tower for $175. Check it out.

will it fit the 3.3 revo and is it faster than a os tm?

I don't have a TZ, so I can't tell you whether it's good or not. But the one you listed has a rotary carb. You probably want the one with the slide carb.

I'd have to go with TM, because it is an easy drop-in and a great mill. The TZ is attractive, but unless there offerings have changed, I think it is generally setup for a bumpstart. I'm not sure but I don't think it mates well with the e-z start.

The 3.3 is not something I would even consider given the rash of conrod problems people have had with them.

Heres the o.s. 18 tz you want.
its 130.00 but it will need to be bump started

is the tz the one u all would go with? and if so how much is a bump start and how hard is it to do it? there is also the tm and the 3.3,

2.5 flex

so what would u all go with the tz, the tm or 3.3???? and y, what 1 has the most power??? and if we were to race with same trucks, with all 3 motors what 1 would win??? thanks

With the tz you have ot modifie the block, and i do not think the ez start will work eather, but you can get a rotostart backplate for it im sure.

2.5 flex

so you all think the tz?? will it out preform the other 2????

I have 2 3.3's and an os .18 as well as an axial .28 for my revo's. In all honesty the OS motors are the easeast to tune...and the 3.3 is a pain!! But the conrod problem can be solved by swapping out the bearings with the Boccas. The bearings always seem to fail within a gal or so putting unneeded stress on the con-rod. But I have friends that are on their 3rd and 4th gal with the stock 3.3 and have had no problems. People always have a negative side, but never tell you the good about a product.

The 3.3 is a tad quicker than the os ni the long haul but the os is a lil quicker off the lone. It really comes down to user preference in my opinion. It's kinda like a chevy and ford debate.
Just my .02

No its not, chevys are faster, its more like ford vrs dodge, cause no one chalenges the bow-tie. Anyways if i were you i would get a sirio 23, since it comes iwht a header and engine mount that is anoed orange. Not ot mention it makes alot more hp then most 21s and more torqu then the tz, tm and 3.3. Itis a super high strung engine that loves to run at wot, but off the line it is fairly slow, infact it acts like an engine wiht a turbo, once it gets spooled up it runs like a raped ape. OF corse you have to replace the bearings in it wich sucks but i think it is still wortht. If the 23 is tomuch then i would look at the axial 28 and get a bb mount. Ii is not by anymeans a power house, but it does make more torque then any of thease small blocks or midblocks.
