Just needed some positive thoughts from the team, was able to get the pin in. Shifter much better.

Rookie mechanic looking for a pro tip. Got the brass shifter bushing kit from MSA (sucks that you have to file material off to make them fit) and can’t get the pin back in. Many attempts at this blind process. Any ideas on how I can line up the shifter fork holes and holes in the bushings?

No, it did not. Seems to have happened after I painted the air box and changed spark plug wires. Swapped the old wires back just to rule that out and no change.

Tough one here has me scratching my head. As always, thanks in advance to the group for helping think through the issues. Full tune-up and carb balance completed. Based on my cam, the car likes to sit at idle at 900-1000 RPM. Holds this idle while in the garage. After driving for a bit, starts to lose idle at stop lights. Will drop down to 600-700 RPM, which is rough given how lumpy my cam is. Maintains idle in the range, does not fall further or stall. No other loss of power or performance issues. Plugs, wires, etc. in good shape. Any ideas?

@AK260 Thank you for this post, great stuff. Sean should have these on his site for potential customers. Quick question, were any resonators used or straight from header to muffler for your tests?

Is that good or bad?

Thought I was buying a Nissan filter when ordering from Motorsport Auto because they look just like the OEM product with color and characters. Any thoughts on quality of these filters? Also, any thoughts on why the idea of not seeing a Nissan filter under the hood bothers me? Thanks!

Hi guys, any update on this? I've got a similar issue, lots of wiggle from the shifter in 3rd. Only while driving, nothing with clutch disengaged. Transmission was recently rebuilt by a reputable shop.

Love that we're all so dorky on this stuff. Not that this will have me pulling the wheels at a green light, but would like to get thoughts on best plug match. Setup is 280 block, 280zx distributor, standard coil, SU's.

Sorry about that, thought it was clear. I installed a new fuel pump and the intermittent stumbling problem appears to be solved. Did richen up the front carb during tune-up, which appears to have fixed the detonation I was hearing. Only issue now is I need to get the OEM fuel pump rebuilt so I can return to the stock look. New fuel pump off the shelf is an ugly one.

Indeed!

Problem solved, running great! FYI, consulted with a local Z expert and the fuel filter not being topped off is normal. Thanks all for help!

All tuned up. Fuel pump pickup today, I'll report back after install.
