Wow, that triggered some deja vu, Dan. I had a Nissan 300ZX Twin Turbo, and it was absolutely hellish to tinker with. Some of the fasteners in the engine bay screw upward into the block, requiring crowfoot wrenches and a mirror...if a mirror would fit in the space, which it won't. So you're basically doing everything blind, with crowfoot wrenches. I sold the car after one year just because of this. I'll never own another Nissan in my life. Sounds like I should add Honda to this list as well?
