I am on a limited budget and would like to pick up a new engine and exhaust for my revo 2.5. I was looking at the OS .18 TZ and the TRX 3.3 for an engine, for an exhaust i am clueless. Any suggestions?
Well, the TZ does require a little finesse to go in, it's not exactly a direct drop in for the Revo. Also with the TZ I think you have to use a TM crank or get a starter box. You can do the Engine Exchange Program through Traxxas and get a 3.3 for like $135. As far as a pipe, either a Resonator or a Trinity. My preference is the resonator, the sound the Trinity makes annoys the crap out of me.
The biggest difference I can say from the two is that the Resonater requires the rubber coupler still as opposed to a one piece set up by Trinity. As far as performance... I never had the Revo 3.3 long enough to even use it.
If budget is a factor the 3.3 is gonna save you $80 (with the ERP) over the OS.
The Revo headers are a major weak link....with the resonator you still have the weak link. The Trinity uses springs at each connection, much more forgiving!
Shameless plug....I have a sweet Tsais pipe and new Revo header for Sale in the for sale forum.
I'm still looking at motors but i do have a trinity pipe and its great! You have to watch out though, the trinity's diameter of the trinity is alittle bigger and i find that the rocker has rubed a dent in my pipe. You can fix this by making a new longer pipe hanger out of a coat hanger. Just my!
