I'd choose the 18tm over the 3.3

i'd look into RB TM523 also. the engine comes with the header and tuned pipe already.
tons of power...

I had a .18tm in my revo. Loved it. Would totally go one over a 3.3r and just like the 2.5r/3.3r, the electric start bolts straight onto the 18tm

Cheers

a 3.3 pulls
a .18tm pulls more
a .23 rb is insane...that's pretty much how it goes

honestly for the best balance though the .18 is the way to go...these os engines make some serious power...but also remember the 3.3 is no slouch...just not quite a fast

depends on budget and wants really...if you wanna go big block without buying qoncepts kit get .23rb or picco .26max(rb is better imo), or if you wanna have a more direct replacement but more power 3.3 or .18 will do( id say .18 though...you will be pleased)

Just a very dumb question.....
I just mainly run my revo down the block and in the back yard....big hill and some small jumps....oh, and some turkey's from time to time ....would I notice a considerable difference if I replaced my 2.5r with os .18TM?

And looking Tower Hobbies saw a os .18TM "fully modified" ....what is the difference in it and just the .18TM?

Thanks!

oh i believe you will definitely notice the difference. i've replaced mine with a .18, not an OS though, and its really a good upgrade.
