Hey just want to start a discussion for something that's been bugging me.
Really what is the exact reason that everyone whines about the VG30 being such a nightmare to work on?
That is all I ever hear from people. I've owned two Z32's and my dad has owned 3 and sure the engine bay is tight but everything is possible to do in there with enough time. I just wouldn't mind hearing other people's ideas. It seems like people can't wrap their head around me wanting to work on them.

To start, Isn't that knock sensor replacement a PITA?
Twin Turbo, that's a whole system that many cars don't even have, so there's that level of complication added. Dual MAFS and other sensors too right? It's not that a MAF is all that complicated, but then doubling up must add to the complexity a little bit. I think all the little bits that seem just a tiny bit tougher, like the tight engine bay and more, add up to make the overall that much harder to deal with.

I think you might get more conversation in the Z32, general discussion, the engine forums are used less and more specific, but I don't know.

Anyway, I think it's awesome that you tackle these engines with no fear.

It's just another set of parts that come apart and go back together, and all move to complete a task. There's just a lot more to it. More vacuum, more plumbing, more water, more oil, more everything. And the space confounds everything.
