Nice response from Matt Monet there, thanks !!
I was going from the information from his own site where it describes the build up of the car, basically it went along the lines of...
Standard........got a 12
Modded loads of bits.....got an 11
Modded loads of other bits and a touch of gas....got a 10
Totally rebuilt the bottom end ..........hey presto a 9 !!!
Thought this was cheating, returned to stock bottom end....got 11's again !!!
If its as you guys say then fair play to him, most americans describe any bottom half of the engine with ONE standard part thats usually been played with alot (typically the crank) a "stock bottom end" despite forged rods, better studs and god knows what else - the supra community is best for this !!!
I would have been more than happy to put my old skyline on the dyno, it did exactly what it was built for with regards to performance. I would be happy to put the GT3 on the rollers too, just to confirm what it is pushing out, but its normally aspirated so isnt really a comparison, but it does have titanium rods as standard !!!!
I think that a few people are misguided. If Sidious thinks that most skyline owners are not interested in performance, its only the "new boy racers" who are interested in tuning them and dragging/racing/tracking them then it shows that perhaps he has a short memory or hasnt been around very long. Members of this register or its previous incarnation were taking brand new skylines to the tuners and dynos way before most the people here nowadays could afford them. They are cheapish cars to buy now granted for some models, but to tune them to the larger power levels still takes a few more quid than your average Joe wants to throw at a car.
The only "proof" I can give Mr Nemesis (whose spec list I think is excellent, but then I have followed his car for a long time, back before GTOUK became an inwards facing secular bunch of self pleasurers

) that the 6G72 is a relatively "weak" engine compared to the RB26 is simply that if they were that good you would see them in the same leagues for power, performance, and tuning that Supras, RX7's and Skylines are all in. I cant remember the last time someone linked to an Option Video of the latest Wangan run with a "Mighty GTO" sweeping aside all the pesky Supe's and 'Liners (sorry Dino

). I know some of this is down to the car weighing the same as an unbodied HGV, but I would have thought there would still be quite a market for it if it were feasible, and there doesnt seem to be one - so I guess its a few very loyal owners such as yourself who want to battle with physics, while the rest of us start from a better beginning !!!
You might also want to remind yourself of your forbear - Dave Whatever his name was - with the Hulk, a GTO that was to eclipse all others, and certainly had the money spent on it. I believe he gave up in the end, must have been a reason for it !!
I would also point out that I wasnt being nasty to GTO owners at all, and still dont feel I have been, this thread I thought was all good natured banter right up to this page
