if you can pull it off it would be one for the books. but why ruin a honda with a non-honda motor???
j/k
i agree the k series is going to cost a lot of money, and considering ZMR is the swap parts shop would there be a lot of opps to do that to obtain what you need?
how much do you think you could get for the rex?

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
