Kyosho TR-15 Engine Upgrade: Advice Needed

Post by Velocity_Stack » Mon Sep 14, 2015 10:10 pm

I'm looking at upgrading the engine in my TR-15 Ready Set version.

I also have a first gen TR-15 roller, so this question can help me decide on both projects.

I'm leaning towards a .18 just because it would be a larger displacement over the OEM .15.

OS seems to the about the only thing available with the pull start feature at this point.

OS has been around since first picked up a Tower catalog 30 years ago, so I guess they must make pretty good engines.

What are your thoughts on this matter at hand?

By the way, I have picked up a set of engine mounts already, cause the OEM block bolts directly to the chassis from the bottom.

Thanks in advance for any advise.

IIRC LRP has a .18 with a pullstart.  Very good engine as well..


OS is also a very good choice..

Seems like the LRP is discontinued and very hard find, but I like the stats behind it.

Thanks for the info.

Yeah, I saw that Dynamite, but it's going to take the additional parts to make it a pull start.

Since it was originally designed for a Traxxas, I was not sure if it actually fits the standard mounting on other vehicles or if Traxxas has different mounting dimensions.

Let me know how it goes bigbigbrig, if you end up buying one.

the dynamite is a standard small block mount. the only parts you need are the pull start and one way bearing.
The make a platinum version that's a bump start also

Thanks for added info.

I guess any one way bearing and pull start will work?

I'll take a no reply as a yes - all one way bearings and pull starts will work with that engine.


I finally got the OEM engine running and somewhat tuned today.

Although, it's lagging from a dead stop, but screams on top end. (Dynamite pipe)

I tried to adjust the lag out, but not happening so far.


Am talking with a local track I discovered on 1/8 scale buggy racing and engine limits per class and the guy said that there are no *official* engine limits, but everyone runs a .21, only because the larger engines can not be geared correctly.

Kind of makes me think, that maybe I may need a smaller displacement engine for this 1/10 scale buggy.

I like that *out of hole* instant power, like my Savage has with a .32 and a 086 pipe.


I don't know.  Now that it's back running, I have plenty of time to think about it.

They don't have a 1/10 scale nitro class, so this buggy will just be a fun neighborhood toy, as it's always been.


Please keep me keyed into your thoughts though; nothing like upgrading and improving no matter if it's raced or not.

sorry for not getting back to you right away. You need the pull start and one way bearing from a traxxas 3.3

Ah, thanks.

Just noticed it's a rear exhaust port too.

Probably won't go with the Dynamite .19, cause I have 2 Dynamite side exhaust systems already.

OS may be the only choice.

Not in a hurry though, now that it's back up and running.
