What did you do to your Z this week?

Adjusted the tappets on my Samuri and cleaned/oiled the K&N air filters. Went to a local autojumble/show this morning and then changed the oil when I got home.

Decided to do a compression test and thought all went well. Then when I came to start it afterwards no joy! No sparks. I thought I may have damaged the 280ZX dizzy module or coil (I just left the plug leads hanging when doing the test) but it appears not because I swapped for the ones off my 240Z. Also swapped the king lead and rotor arm. I've got 12v at the coil. I'm stumped so may swap the dizzy tomorrow.

Any ideas?

@rob - I had this a few times when playing with the car. Mine was nearly always a loose connector on the coil side of the circuit. Usually the 0v one comes off / gets easily knocked off mine.

If you take the coil cable off the dizzy cap and point it to a naked body bolt, do you see it sparking when you crank the car?

I very much doubt that you’ve damaged anything as I always did / do compression tests with leads hanging off. Heck my coil even once did a plasma ball impression sparking onto anything around it and yet all is still well.

Hang in there I would wager it’s just a knocked off or loose connection.

Thanks guys. Ali no loose connections because I've swapped the coil. I have had No 6 plug out all the time during testing and touching it on the engine. Jon why would the stator work fine this morning and not later. Something has happened during compression testing or oil changing - strange.

I'm very fortunate to be able to substitute bits from my other car. Also this could be the time to install my brand new Mallory dizzy and 'HyFire' ignition box of tricks?

I've swapped my 14" wheels out and put the 17"s on. I wanted to test whether it was all the movement in the tyres that made it feel scary on track at Donington yesterday.
I think the answer is yes, although hard to be sure on the road. I'd like to have another session at Donington now. I think I do need to figure out a brake upgrade.

With respect Jon 14" wheels will not be the reason you are scared. I did trackdays for years on 14" wheels. You need to get on track more and get used to a car sliding.

Old tyres?

They're 2 year old Nankang NS2 at 34/36PSI. I think the main thing I didn't like was the lateral movement in the sidewalls. There's a lot. Pushing the car in the side at rest has it wobbling like a jelly.

I put the new tweaked R32 brackets on the front and changed out the front flexis to a new design and bled the brakes again on Friday arvo ,

And then I went out for a quick test drive yesterday with my friend in his rs2000 which ended up being about 250 miles , but what a great drive upto Elan valley and around mid Wales in the glorious Welsh sunshine

How does the performance of the RS compare?

My mini with 10" wheels and a Yokohama 165/70/10 tyre did exactly the same thing - negative camber fixed that issue EXTRA;)

The orange with the bronze RKRs looks a great combo Gary.

Have you thought about rear disc conversions at all? I'm frustrated with the options available tbh; the key problem is the poor handbrake efficiency with the common Maxima/280zx based options. The alternative is the kit offered by Silvermine and others that uses Wilwood calipers with separate handbrake calipers. I'd like to do something similar, but more economically! Something to break from the limited, overpriced alternatives anyway. Fancy another project? EXTRA:D

I've just had this conversation with my mate, all of the brake conversion options tally up to a small fortune if you're doing fronts and rears.

I think we're going to look at S13/S15/R32's and see if we can get anything to fit by making up a bracket. Anyone else done something 'different' with their brakes?

Wilwood have a rear caliper with an integrated handbrake that T3 use on their rear brake kits.
