Motor head upgrade

[Joek72]

Does anyone know if there is a ported mod for the stock motor in the losi 5t v1.5 29cc. It is a four bolt head. I am not sure what I am looking for in terms of bore size and the stroke I think it is.

Pretty sure that engine can go to 30.5cc...esp has a solution for you... I believe you will need the crank to go up to 30.5cc.. not too sure but building the engine is super easy

Esp 30.5cc or obr 30.5cc. Both are great. I had the obr and it was a proper ripper . You'll need a +2mm crank with the obr one though, as it isn't included

 

[Joek72]

Thanks the link that you posted is a direct bolt on for the 29 dynamite. With the piston
Also what is the difference between a 2mm crank and 2mm stuffed crank

A crank not conn rod right. LMAO

 

[Rep732]

Yes a whole crank

 

[Joek72]

The dynamite motor say on the top plastic cover that it is a cy motor will that matter

 

[Rep732]

I'd think as long as its a 4 bolt head you should be fine.

Edit oopps

?

Someone correct me if I'm wrong but I thought o ly difference between cy and zenoah was the clutch hardware?

 

[john addinall]

nope. zenoah is in another class. CY might be better than rovan and king motor

 

[Seandonato73]

Cy is decent. Parts are interchangeable with zen parts for the most part. The head kit will bolt onto a cy block.

Iv used cy bits on my builds coil ,flywheel and clutch plates fan covers all fits and works no problem

 

[Rep732]

I had to run a cy clutch plate/holder on my kraken for fitment issues. Their stuff that doug mentioned works just fine. To make this easier buy a zen long block ,real walbro 1107 and transfer all your other bits over and bam perfect

So are you saying to get this and transfer all of the missing things and bolt it up and I will be good to go. will this bolt right in to the losi if I take all the stuff off my dynamite 29cc and the clutch and housing
And I also already have a ddm pipe which I hope will work to

 

[Rep732]

Yes it will and correct use all of your stuff off the 29cc to finish the long block...stay with the cy clutch housing or if you want theirs choose cy and don't get ceramic bearings get nachi

 

[Joek72]

That’s what I am going to do what do you think about that motor has anyone see or have it

 

[Z.hb71]

That's what I used to have, proper ripper

 

[Rep732]

^ there's proof right there. You will be pleasantly surprised at how a modded engine responds over your stock cy. And a pipe can just push it to being better... what pipe do you have? Do yourself a favor tho and buy the proper flywheel puller off ddm to make the swap smooth. It also can be used to remove the clutch holder
