Engine ID help

[blown67]

I know its a Dynamite, that much was easy, I believe its a .12 There are no other markings on it. I pulled it out of a very old RC10GT https://www.rcnitrotalk.com/forum/showthread.php?t=69370 I wanted to get a new piston/sleeve for it to keep as a spare, but not sure which one to order, theres the 12s and the 12spd and so on, any help would be appreciated.

That thing looks pretty old.

By the time you scrounge up a P/S for it, you'd probably have been money ahead buying something more current.

I think the S in 12S just stands for "side exhaust". The SPD I think is just side exhaust but ported for more power.

Just checked out the current equivalent to that engine:

$70 brand new. Considering the piston/sleeve is $30, con-rod is $20, OWB is another $10, you would definitely be money and headaches ahead just buying a whole new engine.

thanks for the info, I found the p/s shipped to my door for 17 bucks, for the 12s, and a con rod for 6, I was thinking for less than 25 bucks I could at least have a spare motor for the traaxxas pro .15 when I send it in for the replacement engine exchange program.
