It's interesting to see how much resistance there is to this concept amongst some of the z-drivers where the standard mentality is "bigger ports=better".
Aside from the obvious oversimplification in that scenario it is important to remember that ozconnection (and myself) aren't driving z's, we drive c's (cedrics, 240c, 260c, 280c, and in the 330 body code also gloria). Compared to the nimble Z's with a tare weight of say 1067-1200kg, the cedrics are the lumbering brontosaurus of the nissan Lseries equiped vehicles(excepting the patrol of course) with a tare weight closer to 1500kg.
Consider trying to drag your race-ported Z whilst bearing the burden of an entire seized motor in the boot(trunk) and you'll have some concept of the challenges of such a build. In this scenario Torque is king.
Beleive me, my 260c coupe was ported & cammed before it got to me and im strongly considering pulling this "performance" head for something narrower. To the Z-driver the fact that their engines don't kick in until well beyond 3000rpm is water off a ducks back but if you're running this style of engine in a luxo-saloon, getting off the mark without changing your clutch twice a week can be a mite troublesome.
The obvious response will of course be "why dont you get a Z then?" the response is simple; why to Z drivers spend ridiculous amounts of time and money on beefing up and antequated Lseries when they could get the same results from a modern transplant and a cheap turbo? -nostalgia, pride, stubborness and passion.
Certainly for a daily driver this is a well-notable direction to hold on to the heritage of the vehicle yet still maintain the capability to express your engines "power" without looking like a manic jockey flailing his screaming horse unsympathetically through first and second gears. The horse will probably love you longer for not revving the guts out fo it too...
Perhaps some of the Z-drivers should consider a page from the cedric book?
Food for thought...
