hello there to the masses...does anyone have any experience or knowledge on a XTM .21 PRO? Are they good engines for a TMAXX? If so, is it a will it fit in the older TMAXX?

I don't own a T-Maxx or have any experience with one, but I do read a lot of posts in this forum and one engine that keeps popping up as a good replacement engine for the T-Maxx is the Sirio .18. Big assed wheelies I think are the order of the day.
Also the OFNA hyper .21 is good but I'm not sure what mods are required. I'm pretty sure the Sirio is a straight replacement.

For the 2.5 Maxx. And from what I have read a great engine at that! All other .21's you will need a conversion kit! XTM,Hardcore and New era make good kits. It just depends on how much you want to spend!

If you go with the Sirio or TRX 2.5 and have an old T-Maxx, you would need the conversion kit ( around $40- $50). I learned the hard way. I converted an old T-Maxx with an OS15-cvx engine and had to buy alot of parts, ie throttle servo post, clutch nut, starting system ( do you want pullstart, ezstart or bump start), exhaust for that engine & so forth. So be careful. If you want to upgrade to wider suspension also drop me an e-mail.

Thanks guys for the replies...I was ready to buy the converion kit at the same time...found a few XTM .21 PRO's on Ebay for under $70.00 and was wondering if it was a good buy..

Hey JCJR..have you found any new spots in our neck of the woods for running/bashing..you have a Savage right??
