yeah mate simple as. theyre exactly the same, just the v8 is 5mm bigger inside. some people will say they are worth getting some will say not. i personally have used the standard 60mm TB, as well as the v8 65mm TB, and also a bored out 70mm TB, and i recorded no power gain at all. my 0-100 did not change at all, the standard 60mm TB is more than big enough for a stocko vn or vp v6. you would only really benefit from a larger one if you had some decent internal modifications to your car. they do however give more throttle response (which means you only put your foot down a bit and it seems to take off like you had your foot down alot more) but when at full throttle it feels no different than full throttle with a standard TB. alot of people (including myself) have gotten whats called the 'placebo' effect when first driving with a new modification on (when it seems better but its actually not), but yer as i said when timed they werent any better than a stock one. in saying all that though, that is just MY opinion and im sure you'll get some people who disagree with me lol
