Thanks, I neither love this appendage or loathe it, I'm somewhat in the middle. I think it would be more at home on an S30z with flares and that "fat" look. Than on a standard body S30z.
I do like the idea, but think in execution it's a bit sloppy. Too big a lump. A more subtle hood modification to improve cooling would be better. I guess Nissan eventually put the vents in the hood in later S30z's to achieve the same thing, but I don't like the look of the "260z" style vents. I've always felt they look cheap.
I'd probably opt for vented inspection flaps instead. Easier to replace and cheaper to modify than a good bonnet.
