Well, for one, you are asking a biased crowed here
So with that said, I would go with the GS-R. Sure it may cost a little more, but you a nice B18C to work with
Of course, you could buy an older civic and drop $10,000 or so in there right off the back including a B18C, B16B, or H22A swap...I like that idea as well.
