I don't know a thing about the Skyline motor... so I'm not voting for now. If someone wouldn't mind providing technical specs on both of them I might vote.
Don't just vote, either, people. Actually give reasons why you chose which one you chose.

I voted for the Supra engine because since it has a larger displacement, that means the parts are stressed less than the ones in the Skyline engine. From that conclusion, that means the Supra engine can be more reliable than the Skyline engine, assuming that the owner knows how to take care an engine. That's why I voted for the Supra engine. Reliability.

I could be wrong because the nature in these two engines could be different. Perhaps the Supra engine can have more vibration than the Skyline engine, or the Skyline engine may have a problem that the Supra engine doesn't. I don't know those details, but just comparing numbers, the Supra looks better on paper.

Guess What I chose?........the skyline....DUH..I like the overall feel of the engine..the mass HP potential...optimised torque curve....and the way the engine interacts will all the aother features...ATTESA E-TS..Super HICAS....plus thanks to that cool little LCD in the R-34 you can tell exactly what is going on

Theres a supra made by the people at exvitermini.com. That supra has the RB26DETT in it. Superior Vroom.

Sorry, I was wrong, they only have a video of a supra with a RB26 in it, they didnt actually build it.

Both motors have pro's and cons. I am treating this poll as though both motors are stock standard.
2JZ
Pros
3.0 litres - hard to beat displacement
ignition system is reliable
Very strong off the shelf - Bottom end reliability is second to none.
Loads of torque - good pull off boost
Cons
Uses a sequential turbo setup - not reliable at all
Low rev'ing - hinders future upgrades until it is sorted with major work.
Intake and exhaust setups not effecient
poor head design and cam profiles
RB26
Pro
Parralle turbo setup - hits boost quickly no problems with over boosting.
Head is one of Japan's best designed for flow
Extremely strong crank- factory billet
Intake and exhaust systems are designed for flow
Very high rev'ing (8,250 factory rev cut)
Cons
weak pistons for this great motor
Air flow meters are prone to failures
Weak valve springs and valve guides
Con rods only good to about 550hp
ceramic turbos- die easily
fuel injectors too small (IMO)
I still have to go with the RB26 overall. Out of the box it is a better motor. Both are great engines and you can find faults with either.

I don't know why I didn't think of/mention this in the beginning, but yeah the RB26DETT would be a better engine out of the box, The 1/4 times may be to the point that it's a drivers race, but on the road course, due to the RB26DETT's higher rev's it would have higher acceleration out of the corners due to it's greater leway in the RPM factor
