LS/VTEC turbo or B18C1 turbo

ok so i've been looking for cars in my area and i've found a LS VTEC swapped civic and a B18C1 swapped civic, my questions are...

1. Which would be better to turbo? (reliability wise)

2. The B18C1 civic is gonna cost me an extra 2,300$ more then the LS VTEC civic (the B18C1 has more work done to it, body/suspension wise) so is it worth paying the extra cash for it? or would i be better off buying the LS VTEC and saving 2,300$?

Thanks in advance!
