T-maxx engine swap????

[west virginia krawler]

Hi guys, just to let you no this is WVK's step dad. Hes got tired of his T-maxx 2.5 and tore it apart. (Kids nowa days) And I've got his 2.5 motor, and would like to swap his into mine. My t-maxx is the very first model and my motor is all wore out. So my question's are...... Has anyone done this swap? Is it a difficult swap? Is there a lot of rigging up you have to do to make this work? Or would it just be better to buy a old style motor? He's said that this is a help full website. I hope that you guys can help. And no BS!! I dont deal with that. Thanks for the help,

Traxxas makes a kit that lets you bolt up a 2.5 into the old maxx. I think its like 35 bucks.

EDIT: here you go. its on sale too

Yep and it pretty much is just a slide carb modification.
Traxxas also offers a trade up program if you would like to get a 3.3 engine. That will also fit.

You may need to flip the motor mount around (or use the old 1st gen one).


When I installed the TM323 into my T-Maxx (Also 1st gen) I had to take the engine mount off and rotate it backwards.


I just made my own slide carb linkage.

If you need it I could post a close up pic of the linkages. All it really consists of is a pole and a servo horn.

Edit :Here is a better pic. From when I had the CVR.15

Just for kicks.

Sweet thanks a lot. If you don't mind could you post up a more detailed picture of the linkage set up? Thanks a lot

For the pivot point I put some thread lock on the screw, tightened it till it was snug, then backed it off 1/8th turn. Once the thread lock drys it will hold the screw in fine. Because the screw is not tight it will allow the servo horn to turn.

I think the post I used was from a 1/8 scale buggy servo tray. It was just a random part in my spare parts bin. It is rock solid though I does not wiggle at all and I have decent throttle servo that can indo the truck quite easily if the brakes are not applied carefully.

Oh yeah one thing I neglected to mention.

If your radio has end point adjustments you can set it up just like mine.

But if it does not. Instead of using fuel tubing on the control rods use pen springs it will allow more free movement of the throttle servo.
