one of those questions: between 2JZ-GTE and RB26DETT

Actually, the 2jz-gte longblock (head+shortblock), totally bone-stock other than cams, has proven itself to reliably handle 850rwhp (1000hp at the crank). There are several examples over 800rwhp using a stock 2jz-gte on T04R.com, and other websites...here's just one:

Also note that 850rwhp is nowhere near the max for the stock 2jz-gte, it's just the number that's often quoted as a max-with-reliability/longevity. However, almost 1100rwhp (almost 1300hp at the crank) has been produced on the dyno with a bone-stock 2jz-gte shortblock!

I agree that someone that hasn't heard about the 2jz-gte's capabilities might think that 800rwhp or even 800hp at the crank on a stock engine sounds like bull, but it really isn't!

Yep an 800hp Supra can easily run 10s with the right rims&tires, and a good driver. I'd have to guess that the 2jz-gte's capabilities are part of the reason that the MK4 Toyota Supra has kept such a high resale value.

The mistake you're probably talking about is trying to run too much boost on pump gas...and yep that'll wreck any engine (no matter how much you spend on the internals). Properly tuned, and with a sufficient amount of octane in the tank, 800rwhp with a bone stock 2jz-gte is a walk in the park.

Sorry about the digression/thread-jacking ... to be honest I don't know much about the RB26DETT, but I have heard that it can't support anywhere near as much hp as the 2JZ-GTE in bone-stock form. Fully built, both the RB26DETT and the 2JZ-GTE are monster engines capable of 2000hp+. Fwiw, I agree with ARZ that the 2JZ-GTE has better support in the US...I'm not sure if that is also true in Australia though. My admittedly biased opinion is that a 2jz-gte would be the best choice.
