It just a noob question, but I think it might be possible.
According to some Fit can swap with K20a, if I try to swap all part from FN2 to fit (suspension set with 5lug and big brake and K20Z from FN2)
Is it possible to do this???

 

I'm not sure since you have the Thai model. I do know that many people have done a K swap so it can be done but I have only seen them done on US, Canadian and Japanese fits. As far as a 5 lug swap, I'm not sure that would work given the rear axle of the fit.

 

I try to search on the internet. Many fit swap pic, they usually use 4 lug except J's racing Fit. In J's racing fit use 5 lug axle. (I'm not sure about this and how they do.) In Thailand, many shop will convert by modify but it's not safe. Right? If i want to swap 5 lug axle and don't want to modify. Part from which model, that can use for swap.

 

Why would you want to take the trouble to swap from a 4 lug to a 5 lug?

 

I can find 5 lug wheels from aftermarket easier than 4 lug wheels, and I want to use big brake.
