I've seen pictures/videos of K20 Fits, and it's what I want to do to my Fit when I get it. So my question is, would it be better to stay with the stock tranny or is there a better tranny out there with taller gears? Let me know if anyone has done some research on this.

 

You can not utilize the stock fit transmission along with a k series motor.

We're all n00bs at somepoint

Oh, sorry. I am kinda new to the import scene, or any car scene for that matter, but I thought the k20 flopped right in but I guess I'm wrong. So what kind of tranny goes with it? The stock one that comes in something like the RSX?

There aren't many if any USDM fits with a K20 swap, I belive most of them are shop owned and from Japan.

The K20 doesn't just drop in, or a lot more cars would have them even right now. It seems to be a fairly complex swap.

Anyways, you can get a K20 or K24. The RSX-S, new Civic Si, and Acura TSX are the best choices for a K series, because the others don't have the 3rd set of cam lobes that make those engines performance models, that and higher compression, etc.

You can get a 5 speed or 6 speed transmission. I'd choose the new 6 speed from the new Si because it comes with a limited slip differential, which would be very useful on such a light car as the fit (2400 lbs). Otherwise, many aftermarket companies such as Quaife offer LSDs you can put in yourself. But 6 speed is good.

I don't know of any K20 swap Fits here in Japan except for Mugen's which I think they already scrapped/crushed...please show me an example if you know of any.

That's one, I believe gotten through special connections in Japan. Mugen Dynamite is the only other one I know of. I thought Spoon was working on one as well after they exhausted the stock engine.

Those are the only ones I know of and are both connected to Japan and not US.

 

I think they did that one up locally (in the US). Over here in Japan no one really bothers with the Fit performance wise. I have never seen personally (or even in the magazines) of a Fit with a K here in Japan. Cool to see that the Fit is getting much love in the US

 

If you look it's definitely a RHD car, with the JDM tails. It may not be a Japanese company per se but they got the car before the general US release date which means they had a container hookup to do the swap in.

Most people buying the Fit here don't really care about that right now, they're enjoying the fuel economy.

 

N1 concecpts is the only one worth looking into. All the others are just welded in sideways and can't go more than 10 mph...
