Couple things...
First, I am a new member here.
Great site! Been viewing it for a long time and finally decided to join.
Secondly, I am one of the head moderators at Supraforums.com, and the shop that built the Camaro in question posted the photos over there. The car received the same mixed reviews that it did here. I am not too much of a fan of the car. I can certainly appreciate the time and effort involved in the build, but a Camaro that doesn't
sound like a Camaro just isn't my cup of tea.
Lastly, in regards to high-horsepower Supras, while the power curve isn't exactly a mirror image of a Viper, it is most definitely useable. With so many improved turbos using ball-bearing technology, EFI systems with anti-lag, two-steps, transbrakes, etc., many well-built 2JZ cars are leaving the line hard under boost. Plenty of 10, 9, and even 8-second street-driven Supras running around on the stock IRS putting the hurt on trailer-queen V8 cars. Turbo lag is overrated---if a Supra with a large turbo can't get off the line easily, either the driver can't drive or he isn't using the right equipment.
Personally, I sold a 10-second street-driven Vortech-supercharged F-body to purchase my Supra. It is my first import, and pretty much the only import I would consider building in to a high-horsepower monster. The rest of my fleet is all V8 domestic iron. The Supra is definitely my favorite car---handling, braking, comfort, power, uber-reliability and sexy looks make the choice easy. Hard to beat an overbuilt inline-6 that will handle over 800hp on stock internals.
Chevy V8 in to a Datsun 240Z? Sure! That is an upgrade.
Supra I6 in to a 1st gen Camaro? Meh... Not for me.
