My now old and worn TRX 3.3 engine for my revo has died. What engine do you recommand that i upgrade to? I want to go as big as I can. I was thinking of something like a WASP .28 Big Bock. Give me some suggetions.

with a bb kit

jeff789

will it drop in with a bbk no problem?

If you plan on dropping in a BB, I would recommend Qoncepts BB kit. Its by far the best BB kit available.

Picco 26Max, 1st choice
OS 18TM, 2nd choice
OS 30VG9w/qoncepts kit) 3rd choice

high voltage

is the picco as reliable as an os

IMO yes, but it is harder to tune. I wouldn't put an axial in a revo, but that's just me. I'd say you should look at

18 TM
18 TZ with the slide carb (for on road tourers and ST's but is AWESOME for a revo)
21 vz-b v-spec
Picco .26
SH .28 P6 or P3
STS .28
XTM 457 pro
LRP z .28 spec 2 or 3.

i used a new era bb mount in my 3.3 w/ an axial .32. i already had the motor from use in a warhead[:'(]. i checked bb mounts, and what i found was that the new era was the only one that would allow use of a roto or pull start. i think all the others require a bump box.

Yup, but it does need to be sealed before being put into operation.....then tuning will be much easier, tho tuning through the first few tanks should be minimal. The engine is TIGHT, it will build temp fast, especially on the first tank. When it hits 260, shut it off and let it cool(piston at BDC) and continue this through the first 2 tanks......then it will start levelling out on temp and responding properly to adjustments.
