I went out in a friends p100 24v BOA a few years ago and can safely say it would trance my standard saph at the time. I was shocked how well it reved compared to other 24v transplants , obviosly the p100 weighs less but was still 4x4. It was a standard engine that just revved its tits off for a v6. My friends xr4i 24v goes very well too . I love the way vauxhall are such a hard to beat car when it comes to pure street race .
