Further analysis shows that the damage to the metal happens when the nut is removed. That's probably how the split washer works. I've got it as straight as I can; any more and I'll need to adjust my alignment. Its between two splines on the threads.

I put a Momo 3503 adapter and momo wheel on my 280zx, but like a dunce, its crooked so I need to take it off and start over! Upon removal, the split washer had clearly carved metal out of the adapter - and the nut was also marred. It also appears that everything is too thick; the nut does not seat all the way past the threads. What am I doing wrong here?

I pulled my tube out and tapped a 3/8ths npt bung in the hole. I had to chuck it up in my drill and sand it down. I might've put in in the freezer too... But it worked

The momo 3503 is 80mm tall. I measured the stock wheel to be about 375mm in diameter, the thickness is about 25-30mm, and overall height is about 110mm. Meaning, a 30mm dish steering wheel on the momo hub would be very similar to the stock setup.

Ha, no worries. I just got the email myself. I ended up with Sparco R100's. They're ok. Not great, not particularly comfortable, but they fit and are supportive. I made my own brackets, had but later removed sliders to get lower, and replaced the seat belts. I moved the receptacle to a trans-tunnel mount at the same time. My biggest complaint right now is how the seat belt bumps into the wings at the top of the seat. Anyways, thanks for finding this and the reply

How tall is the momo 3503 adapter, does anyone know or could you measure it? I'd like a new wheel in my 280zx but do not want it too much closer to me than stock. I'm looking at some 330 to 350 mm sparco wheels but they have different amounts of dish too. Thank you!

Here's a photo from my 82:

Good info, great to know. I have a set of Sparco R100's coming in the mail soon - I (thankfully) decided to pass on the used 350z seats I'd found. Phew!

I'd guess return shipping will be killer. Unfortunately I don't live nearby any OMP or Sparco vendors.

I'm looking for new seats in my 280zx for safety and support during HPDE. I see a lot of hype here about the Sparco R100's, which a tape measure shows ought to fit in the car. I'm also looking at the OMP Style, which is slightly larger - roughly the size of Corbeau A4's. The salesman at the vendor I called said the Sparco's are not very comfortable, but that the OMP might not fit in the car. Does anybody have thoughts or advice here? Thank you

These are the seats from MSA, right? Do you know where they are made? How is the support during spirited driving?

Does anybody have pics of manual 350z seats (2003) in a 280zx? How are the brackets done? Does it raise seating area significantly? Thank you!

Chicken man - you have mail 3) sorry, the intercoolers are all in boxes. I went on an EBay spree, but haven't installed anything. 4) Intake is the stock airbox routed through 2 1/2" mandrel bent pipe to the turbo 5) Jpipe is here: ^ This pic is slightly dated. I have a Champion radiator and electric Spal pusher fan now. I've also installed a catch can between the block vent and PCV. Re, alternator. Great question, no idea. I have a Dodge Monaco alternator installed, and I recently put in a car stereo noise filter to try to dampen some of the voltage spikes you see. I'll look more closely at the gauge in the car and wiring I did to see if I spot any issues. Thank you!!

Hi guys - I'm in a crunch here. I have a track day coming up in August and I need to do something about my high IATs. I got some help on msextra (pulling more timing, richening up the AFR targets in boost). But - what should I do for a bit of insurance? - race gas. I can get 100 octane at the track, or additives - colder plugs? I have BPR7ES right now. BPR8ES, or BR8ES maybe, but does this affect the tune? - methanol injection? It would have to go in the j-pipe inches from the throttle body. I might be able to move my IAT sensor, which is currently in the J-pipe - intercooler. I have an air-water intercooler and radiator but I'm missing the pump; I also have a Starion intercooler. Either of these would take me a while to install. Here's a shot of a log showing the high IATs. I've since made some adjustments, and the pinging is mostly gone. Here's my map, which is slightly modified after the above datalog was made. Note that my AE is not tuned properly, and I think my temperature correction needs work too. Car: 1982 280zx NA to T conversion, MS1 running Msns-e on a v3.0 board. Locked VR distribution. DSM blow off in stock J-pipe. Magnecor wires. 93 octane fuel. Thank you for any advice or suggestions! And, I haven't been on hybridz in a while; glad to see my ID still works!
