Swap LA1 with LX9 or LZ4
I read here about doing a simple LX9 top swap on an LA1. I think a top swap would be ideal for me, as it would increase power, and (according to other online sources) slightly increase mileage. Which is what I will do short term.
I was thinking, when I get enough money together, maybe swap for the LX9 altogether ( I know some adaptations would need to be made), or maybe the LZ4 (3500 vvt). The LX9 swap, with adaptations seems easy enough. But what of the possibilities of swapping the LA1 with the LZ4? Again, adaptations would need to be made, but I think may be a possibility.
What do you all think?
