Will a .18 motor fit in my 1/10 TS-4N?

Just saw this;

Will it fit in my car? Are .18 still 'small block'.

Also my old motor is side exhaust too, will I be able to reuse it?

i have since fitted a .18 epic into a 1/10 tg10
required a few different things to b done.. such as a much stronger clutch setup/driveshaft/2speed
but cant see y it cant b done with a bit of thought into it

It depends whether the .18 you've linked there is a medium block, for T-Maxx/Revo, or a small block.

Most manufacturers have a .18 out at the moment, and the best I've seen are the Epic, which is a rebadged Tamiya motor with a few tweaks (as fitted to the TNX monster truck), or the new O.S. CV-R .18. The Epic is rated to 1.8HP, the O.S. is rated to 1.6, but both are very similar in their speed, with the Epic having more rpm, and the O.S. having a lot more bottom end and mid range torque.

That particular one there, is 90 bucks, and I very much doubt it would have the claimed 2.1HP for that price. It doesnt say whether its a medium block or a small block, but I honestly wouldnt bother.

For that kind of money, you could buy a Team Orion Wasp .18, rated to 1.5HP, and its guaranteed to be a quality motor..

Yeah, u r probably right. I couldn't even find a review/spec sheet of that brand of motor on the net.

I'm up for a new pullstart for my TT which is $30 so I was considering a whole new motor (that one is $90) because the TT motor is probably half-life even though it still runs well.

Can you guys point me in the right direction for cheap motors?
I'll do a google for that Wasp u mentioned.

I've bought at least 10 grands worth of stuff from them, and they are always reliable and have great prices...

I've never done an engine swap before. What sort of things do I need to make sure of before I buy?

I know I need rotary carb, small block

what else?

[BALISTC]

Find out whether the engine is an SG crank or threaded. I'd say it would be threaded, most side exhaust engines are.

Its normally quite easy to fit a slide carb, just have to rotate the throttle horn 90 degrees to make it work.

[azzachaz]

OK cool. Slide carb opens the options a bit.

will I be able to fit on my existing flywheel/clutch (assuming I dont go overboard with a large HP motor)?

Some TS4N's came with the EVO (1.1 HP) motor with the same clutch as mine.

[azzachaz]

Also, are pull-starts (the actual part, not pull start motors) a generic part? i.e. can I buy a motor with a pull start and swap it over?

[BALISTC]

If you use an engine with the same crank setup as your stock motor IE SG, or threaded, then the flywheel and clutch should fit no problems at all.

Also, depending on what type of motor you have, the pull starts may or may not be the same.

I've found there are 3 different types of pull starts. Tamiya style, which will fit HPI engines and Tamiya motors. They have a pin built into the crank to allow for the starter shaft.

Force pull starts, which are a small diameter and are found on Force motors. They have a removable starter pin in the crank that likes to snap on occasion and cause all sorts of starting problems.

O.S. pull starts, which are a large size and are found on O.S. motors. These also have a pin built into the crank also.

I'm quite sure the Tamiya and O.S. pull starts are the same physical size, but the backplate has a larger hole in the middle, and the starter shaft and one way bearing a larger in the O.S. engines.

You cant use different pullstarts on different motors unless they are the same orientation. The starter shafts are normally different diameter, and the one way bearing is different also. Years ago, I converted a Force .15 to Tamiya pullstart once, because I didnt want to fork out big bucks for a new pull start assembly (this is before I discovered online stores). It involved grinding down the Tamiya backplate to allow it to fit inside the Force crank case, and it all went well because the Tamiya 1 way bearing and starter shaft fit no worries.
