Default Need help on torque converter install

My first time posting here lol

so i have a go kart just sitting in my house and all, it runs, but i wanna make it a little monster, and i want to start off with a torque converter, the problem is, it doesn't fit, and i think it'll need some jackshaft work.

So, wich jackshaft kit would you recommend me? is it the ideal work to fit the torque converter?

The Kart is a FunBikes Drift 2:

JACKSHAFT??!
I can't see why you'd need one!
maybe some engine mounting work or maybe a different engine(emphasis on maybe), but probably not a jackshaft.
Most of the time, jackshafts are not needed with TCs.
We need more details, more pics!
What engine?
But seriously man, NICE KART! Suspension, two seater, looks like a live axle.
And apparently, you have access to a photography studio! Unless those are stock pics, which I think they are.

Default yes they are stock photos lol

here are some other photos of mine, is practically the same 196cc clone, live axle, and shocks, 2016 model.

Do you really think theres a torque converter for this setup?

As you can see, the manufacturer put that weird wet clutch in order to properly fit the chain.

What you got there is a better setup than using a CVT...
The wet clutch system can handle more abuse than the CVT... This also has a redux to it... Im going to guess a 2:1...

Off hand this looks like the bolt verity not the modified sideplate version... So if your set in getting a cvt then it should come off with out hassle, and hopefully have a long enough shaft left.

So establishing what you want, Low end off the line or top end speed...
Then change gearing to suit...

Yeah I was gonna say...
That is DEFINITELY a reduction box(Some Briggs nowadays even have a 6:1 internal!).
Any particular reason you want a TC, or have you just heard good things about them?
Now if you got a different engine, then you'd have a whole 'nother party.
Is the engine branded? Probably the first step to turn it into a little beast would probably be engine mods.

6:1 are as old as the 2:1..
downside: none has one with a clutch, they're all direct drive..

wet clutch is much better than a Torque converter,
I must agree (more reliable, much better efficiency etc..)
only downside: it's 2:1 fixed
as opposed to low torque (2.7:1) AND high speed (0.9:1) of a torque converter.

If you want to swap it out, be aware that you MUST remove the wet clutch,
and likely will need to swap the crankshaft too
(wet clutches require usually metric and -some worse- splined shafts)
TC are all imperial and require straight keyed shaft.

Other than it takes about as much room as the wet clutch is taking now,
and it only offsets the output sprocket inboard a bit (2-2.5" maybe)
so the engine might need to move outboard a bit to compensate if you can't move the sprocket in (which for all I know you cannot)

Wet clutches do handle abuse, but are by no means better than a CVT. CVT provides a variable gear ratio, meaning higher torque while maintaining the same (or higher) top speed.

That being said, it does not look like a simple swap. You will need a jackshaft, you may have to re-mount the engine further to the left (standing behind the cart). Buy a torque converter without backing plate, mount secondary to a jackshaft and run your chain from that.

First i would confirm the shaft is long enough, and will accept a TC before considering anything else.

I would just re-gear using the setup you have now.

What you have to do is decide what outcome you want, and then look at your current gearing and decide whether simply changing the gearing would reach that outcome or not.

Basically.....we need more info from you

You got me when you said "it can handle more abuse", sounds promising! i think i'll keep it and see what happens for now. Thanks guys!

Yup, with karts, more reliable is better for typically finicky go karts.
To make it into a "little monster", just start with the typical mods like a header, high intake filter, and jetting.
Good luck!
