There are a couple of threads running at the moment discussing the 2.6L GT-R Skyline motor. Questions such as power, features, configuration, price, availability etc. can be researched in some links I posted earlier in:

These motors are suitable for an engine swap into any of the inline six (L-series) Z's and product substantial HP.

The smaller, single turbo, RB25DET and RB20DET motors are easier/cheaper to fit and also produce good power. In Australia they're better than a V8 swap - but we have cheaper access to Japanese hi-tech motors than old US V8's.

Thanks, those are excellent links. I'm still surprised that they would put a twin-turbo setup on an inline 6, which is why I was interested in more details. It's kind of a strange arrangement.
It must have been a rather finicky thing to get properly tuned. Don't try this at home!

Cant get motor here because of steering shaft

I read in a magazine that the current skyline could not be brought here without signifacant changes to exhaust manifold design because it interferes with steering shaft when going to left hand drive.That may be one reason datsun(oops Nissan) is considering putting a pissant 4 banger in the new Z.They have managed to screw everything up the last couple years, lets all hope they dont commit this sacrelige against our beloved Z car. Later ,norm

Re: Cant get motor here because of steering shaft

I did read at one time that the GT-R twin turbos were equal size and ran in parallel (like a Masarati TT) rather than sequential. Twin turbos are usually used to provide the required air flow rate, but minimise the spool-up time required to get on boost (by using smaller/lighter turbines).

Cylinder balancng is usually achieved by joining the flow in the plenium chamber.

Regarding the 4-cylinder rumors - I'll reserve my judgement until I see a new Z. I'd prefer a 4-cylinder Lotus Esprit over a V8 Corvette (of course a V8 Esprit is even better . I'd be more horrified if it turned out to be either too heavy, or Front Wheel Drive (eeek!).

Don't foget that the Z-Car is a Sports Car, not a Muscle Car...
