I was planning on using my xpz on my DD so as you can see I want the power lol just going from a XPZ build I had planned to a vs seems like such a huge gap. I mean would putting my IS4 heads on the VS be too much and gen v 3.0 pulley and N*, sfi balancer and so on I have pretty much all parts for my XPZ I just want to be able to have a reliable car of course and be crushin all the mustangs and srt8 out there with a good amount. And of course at the end be happy with it all.
