No not after ultimate performance, but 204 bhp isnt enough. The n séries doesn't address the fundamental flaws in the k wrt turbocharging, there simply isnt enough metal in the right areas. I converted my zt v6 to lpg 3 years ago using a brc kit and it's been faultless since, and with the mileage I do, at the rate I get the only other choice is diesel
i accept what you say about valve seat recession (VSR), the t series will need an additive to combat this.
