Exactly, I like my Toyota Supra to have a Toyota engine. We're nearly complete with the 4.7L build, and we're starting work on a 5.4L stroker motor (2uzTT) that's shooting for the 1500HP range. Beleive me when I say the motor is getting custom everything, right down to custom buckets. The crank itself is being produced as I write this, and is made from a Tonka tough 9310 grade hardend nickel chromolly steel.
My personal motor however will only be 4.8L by the time it's all said and done. We're also in the middle of producing a plug n' play harness that mates the Link G2 to the 2uz/MKIV Supra.
In the meantime, here's a couple more pics of the motor...
