Should I rebuild or get another motor?

[ChrisBlue233]

Hello All,

I rebuilt my engine about a year ago and have done some upgrades to it. Unfortunately, the aftermarket air filter I got doesn't do a good job and grass and dirt made its way around the filter foam. It took a piece off of my piston and trashed the cylinder. There are pieces of metal in the bottom end from I have no idea where. The connecting rod is also chewed up. I have an extra piston and a used cylinder but I don't know if it's worth it. Should I rebuild it to see if it even works or is there an engine you recommend? Thank you.

Go for it, nothing to lose

Pipe down @RcJunkie13 I'm surprised your engine still runs in your 5b....the thing looks like you mow the lawn with it

@ChrisBlue233 you MUST throw that air filter out right now! Just go throw it out otherwise you'll be rebuilding another engine in no time. 1st buy a good air filter with multiple layers of protection that 99% of us here run on ours.

What's your goal and expectations of building a new engine? Are you reusing your case?

I am going to reuse the bottom end. I am not reusing the cylinder as it's pitted and missing some chunks. I have an new piston and another cylinder in decent shape. I have no idea if the bottom end is destroyed. The con rod looks rough though.

Depending what parts your gonna need, a long block would be the way to go

Of the rod looks rough just trash it. No point in ruining another engine here mate

 

[RcJunkie13]

What engine is this anyways?

I don’t buy filters from China

 

[Rep732]

Sorry but id start over with a fresh engine..obviously reuse the flywheel and ignition but the parts are cheap so there's no need to carry over parts that are questionable

And please say you will trash that air filter

I got my air filter off king motors. I have another lightened piston but I'm just wondering if I should buy another motor already assembled or if I should do some upgrades like a long block. The motor I have now is a CY 30cc

Get a g320 longblock

King motor air filter cy engine your missing the true power of the zen engines with that clone junk

 

[DougStar]

Km filters are trash 🗑 buy tgn and put an outerwears

 

[Rep732]

And get good quality air filter oil! The way your going you will have 2 paper weights get a zen and call it a day

 

[ChrisBlue233]

I'll probably buy a zen. I'd rather put the money in now than run into problems later.

 

[Rep732]

Perfect what rig are you using?

 

[ChrisBlue233]

I'm using an exceed barca. I know it's cheap but it was a gift. I've upgrade a lot of the plastic parts to aluminum and I flipped it, crashed it into a tree, and hit a curb and it has yet to break. The only unreliable thing so far has been the engine I've already rebuilt once.

 

[Rep732]

I haven't seen one but yea if you did it once already I'd go for a zen just don't make it too powerful then the drivetrain will suffer

 

[ChrisBlue233]

It's got an upgraded radio, servos, and I'm using a LiFe receiver battery. It's even got a killswitch on it wired into channel 4 but usually the motor blows itself up so I don't have to worry about it.

 

[Seandonato73]

30cc isn't the same as the g320 platform. I don't think the clutch bell will bolt on. Pretty sure the rest will cross over, someone will correct me if I'm wrong.

 

[Rep732]

At minimum get a 29cc zen then

 

[ChrisBlue233]

I'm sure the 29cc will have more power with a name brand than a generic one even if the one I have is 30.
