BLOZ UP

It's on BaT: https://bringatrailer.com/listing/1977-datsun-280z-122

Still here. All the Apex/T3 parts are in. It drives. Needs the brakes bled and some tidying up, and then like the Z32, it'll be for sale. Sad to see it go, but it's time to move on.

Parts! T3 everything except Apex control arms. Ordered the T3 stuff in May and it only arrived earlier last month. Still waiting on a rear disc brake kit. Installed, with the R200 LSD. It did not come with much in the way of instructions, so I initially had the rear drop mounts in backwards, which interfered with the R200 finned cover. So I trimmed the cover only to find out the drop mounts were backwards. Oof, but oh well, I'll only be reminded of that every time I'm under the car. I still need to swap the flange on the differential and am waiting for new bearings and to remove the stock hub stubs.

Hey man! Always nice to see someone from the forums IRL.

Heyoooo Moved. Selling the 300ZX. Went to my first Z Con. Broke a half shaft. Still working on fixing it. Have new adjustable control arms and a LSD to put in. Waiting a spindle pin tool.

There's a sleeve at the base with a bolt that tightens the sleeve. Should have a torque arm.

You can rotate the motor around to make it fit tighter if there's room. I found out this the hard way as it torqued itself in front of the brake pedal during an autocross.

Went to the dyno. Still have to parse the results and match it up with my ECU logs. 320hp @ 10psi, 420hp/440tq at 16psi or so. Might have blown a headgasket. Really unsure. Runs fine, no smoke, but at the top end of the 16psi run the coolant reservoir spewed coolant out 6ft up... dyno operator was not amused. Like it was pressurizing the coolant system. Gonna look at the oil and plugs, and in any case get a bigger reservoir because it does this under non-dyno conditions as well as the reservoir is too small. I had just topped it off the other day in prep of this session, so i was expecting some. Ugh. Wish the motor would just die conclusively instead of this wishy-washy maybe it's an easy fix stuff.

Yep, Silvermine motorsports' electric power steering kit. Love it.

Fixed a couple issues. Timing was off, about 8 degrees too advanced. Distributor was off a tooth. Not sure when I last checked the timing... been years. Figured that would solve my high load/RPM cutouts. It solved hard hot starts. The car still likes 25 BTDC at idle for whatever reason. That's a relief. Replaced the pre-injector filter. The old one was clogged. Guess it is about 7 years old. Oops. Car runs rich AF now. In boost it's 10.5:1. So, went to a autocross and increased boost, of course. It's, uh, fast when it hooks.

Went to another autocross at NOLA. Nice place. Dedicated autox pad. Will go again this weekend I think.

Went to an autocross. Put back in the stock seat (for the 11th time), because the other ones I have just aren't working out for various reasons. Otherwise, - New brake proportioning valve. Bled brakes like crazy but there's still a lot of slack/dead travel before they kick in. The 1" master takes quite some effort, even with the booster to lock them up. Will need to double-check the pushrod. - Electric power steering! It's amazing! - Horn clock ring connection thing started shorting out and honking the horn at certain steering angles (sigh...) - Fuel pressure dropping under boost (it's a Bosch 044, shouldn't do that)

After installing the steering wheel it works great (in my garage, anyway haven't been able to drive it due to brake issues). I still have the tach and ign wires both connected to an ignition source. I'm guessing it needed the steering wheel to correctly sense torque, as you'll generate much smoother/consistent torque with the wheel over trying to crank the hub like I was. There's an autox this weekend that I think the car is ready for so ill report back.

I wired it up temporarily to test. Not sure why there's both an IGN and "Engine RPM" (tach) hookup. I tried without the tach wire, and it seemed to cut in-and-out of assist. Put both to a spare IGN wire and it works much better. Did seem a bit finicky rotating the hub with my hand, but I'll have to put a real steering wheel on it to be sure.
