big block jato

[warriors43]

i have been looking for over 2 months now and cannot find any kit to put a big-block like the axial spec 1 .28 in the jato. does anyone know of a kit or a way to do this without making a mount. i cant just drill new holes in the new motor the block of a bigblock motor is wider. please help I want a big block.

some guy on Ebay makes a kit, but he wants 220 bucks for it....way overpriced...it contains a chassis and mount.

the easiest way i can tell you is to get a standard BB mount and use that and a dremel and drill new holes in your chassis. You can use the stock mount, but you need a dremel to cut it in half for the BB to fit.
hope that helps

Wow, a .28 in a Jato would be crazy. I haven't seen a kit out there for them, yet anyway

Cheers

it would only strip tranny gears or stuff like that.

some people have had good experiences with the BB's, some have not....I think it largely depends on how you gear it and if it has too much low end for the tranny to handle.

I've seen the OS. .21 vz-b was a good choice, the ninja works well, some that i've heard have too much low end for the tranny is the rb523 and the ofna picco....
hope that helps.

not really it all depends on how the slipper clutch is set. the only problem i see with it would be driveshafts cvds would be a must.

Could a jato be controlled with a engine that size? I can barely keep the tires glued on my 3.3.

yes it has been done some dude had a rb 523 in his.

Check with fastlane machine, they make alot of parts for the t-maxx, savage, pedes, rustys, ect. They have posted ton their site they can probably make anything you want, maybe you could send a chassis and they could make one that is an inch or so longer, like the extended chassis on a maxx. I thought about heading out there with my jato this winter to see if they could make top plates, chassis, tranny cases, ect but I havn't torn it apart yet. They are about an hour away from me.

I am using a Picco .26 MAX in my jato. The key thing I did was to get a steel spur gear(I know everyone says to not use it) but the thing SCREAMS now. In fact, I have a hard time keeping the screws in her now

Jato's seem to be made for high RPMs, so the picco works nicely, as it was designed to replace the 3.3 in a revo/tmaxx.

Jato75: I tried using revo gearing with this motor, but was unable to get the mesh to fit... The revo gears require the motor to be moved closer to the spur, and my tranny case is about 6mm too long to allow my mount to work, but I may have found a way around that..

I'm glad you got it running the way you want now. I tried the picco, but ended up getting rid of it on ebay. it IS a screamer, but not the right engine for me. I have a TNT modded 3.3 I'm working on for the spring though.
yikes?
here's the link...i wonder what your picco would do ported polished and balanced?

Take care, man

I surely hope you guys' are'nt thinking of increasing your speed with these truggy motors strapped in your Jato. First off, I did a little research on the axial spec .28 and found out that it weighs a hefty 455g(16.05oz) and peaks out at 36,000rpm. If you have the 3.3 in your jato it's very possilbe that your truck will go slower with this motor installed in your truck, if you consider that a 3.3's peak rpm is 38,100(Xtreme RC Cars Oct 06), and it weighs 150 grams less than the .28 at 305grams(10.9oz). However, I doubt the 3.3 has as much torque as the .28 but, that's what it was built for, torque not rpm. As in the case of the picco .26, and rb TM(Truggy Motor)523 you'll find basically the same information. If you just cant stand it and you want to have more power and speed with the added bragging right's with saying it's a big block opt for the onroad version of any of the top three engine manufactures, if you're trying to build a jato truggy disregard this post. __________________________________________________ ________________ I'm so serious about rc,when I finish my jato build you will know that.........[IMG][/IMG]

yeah, you hit the nail on the head...for that matter, most of the .21's and .28's are built for torque and not high rpm running. The .21's were built for 1/8 buggy classes and onroad 1/8 road racing applications and don't offer the same powerbands the .12's or 3.3's do.
Just because you have a bigger block dosen't mean your engine is faster at all. In fact, the less engine weight you carry and the higher the rpm's are under a peak, with regard to displacement and torque, the better off you're going to be in the long run. The big blocks do carry alot more torque in take off, but i can't imagine needing anymore than i already have...it's one of the reasons i got rid of the picco.
Alot of times we tried running the big blocks here in the north, we encoutered that by the time we had put the engine in with pipe, we had gained not only a serious issue with the center of gravity being too high, but the weight gained wasn't worth the few thousand rpm's we gained, if any at all.
The jato was built for a high rpm engine, and it's extremely sensitive to weight transfer and weight being reduced. Look at how it's geared internally.
That's why i opted for the modded 3.3.

I'm not saying one is any better than the other at all...it just comes down to practical application of what you want the engine to do.
