    Pico Omega.21 in my 4907 tmaxx 3.3

    I recently bought a pico omega .21 racing engine off ebay for my Tmaxx, got it the other day and it's apparent that some mods are in order if this unit is going to work. My chasis is obviously to short, does anyone know of a conversion kit of some sort and has anyone actually done the conversion. Any and all help would be much appreciated.

    You're going to need a big block chassis or a mono block. I'm not really familiar with that engine but you may need a big block motor mount as well. Check out eBay for some good deals. This would be my choice http://www.ebay.com/itm/FLM-Aluminum...#ht_1142wt_772

    Not sure what a mono block is, is something that utilizes my existing chassis or is it something else?

    Is this what the engine you bought looks like?


    If so then you need the correct mount for it.

    A UE Mono Block extends the rear of the chassis to make room for larger engines by moving the rear diff farther back.

    Look out for the tree/crunch!

    Yeah it looks like that best I can tell with the only difference being mine has a light purple cooling head. Where's a good place to get a mono block and will a traxxas ezstart work with this engine as well as my stock clutch bell?

    You have to get the Mono block from UE & their site says it's out if stock.

    If it's the Picco P2 .21 then all you need is the mount.

    Got a pic of your new mil?

    Does it look like this?

    If yes then the Ez start should fit & you need the mount to use it on your maxx chassis.

    This is the engine here, it's not identical to the ones you've shown for examples but it certainly appears to be very close.

    I've got this chassis on it's way and this should eliminate any issues with mounting a big block small block or any other block for that matter. Any ideas as far as what's going to break first with the picco engine, what's not going to hold up on my tmaxx which is all stock?

    I would say to use a dog bone & drive cup for your rear center, I do not know what length bone your gonna need with that chassis though.
    Once you get it assembled you can measure for it.
