Type-R Motor has to much compression to be a good Forced induction car compared to other options. This isn't to say people are not having luck with them. I personally would turbo a GSR motor but LS motors take boost well.

LS is a non VTEC motor. To make an LSV you put the head of a VTEC motor on it. B18C5, B18C1 and B16A are the VTEC heads used.
