Maybe try it with vacuum advance hooked up?

Should have read more carefully. Saw some silicon tape at O'Reilly supposed to temporarily repair leaking water hoses and pipes, but that looks so corroded it probably won't work.

Probably the tube through the intake manifold. Coolant goes from BSPT hose barb in lower thermostat housing to BSPT hose barb at front of intake manifold, through the tube, to Hot=closed thermostat,...

What rpm when it happens? Only at mid-range? Good acceleration from about 4000 to 5000 rpm and from 1500 to 2500?

I don't understand how ignition could cause a problem with light acceleration...

Hi Kats, I saw the Z432 has this nifty coolant recovery system and bracket. Don't see anything in my 240Z engine manual about coolant recovery. Most of the Z cars I see have something, from...

If my cam's battery hadn't quit, I would have gotten more photos. There were some great cars that I didn't get.

Kats, I usually like to see modifications, but the idea of modifying the Z432 (other...

Possibly slack in the linkage?

If it's the cam you could get smaller tires. So you'd have slightly higher rpm cruising around town at 35mph or so. I had the maybe the same problem and going to 65 series instead of 70 seems to have...

This says it all.

I had a similar problem, verified on the dyno as fuel related. Raised the float levels slightly higher than stock (one was way low) and was able to rev higher but there was still bogging on...

Thought you'd like that orange one. Here's a shot of the engine bay.
Sent Mike the CD so all 98 shots should be in the gallery soon.

OK,OK, OK! I think I'll send a DVD to Mike, though. My ISP is getting slower by the day.

My braided radiator hoses seemed sort of thin. Forget where I got them. Nissan sells nice ones, not braided though. wirecare.com has braided sleeving. I put their black braided sleeving on my Nissan...

Close-up of the nitrous injectors. Wonder why there's two for each cylinder. Maybe one is for nitrous, the other for alcohol or something.

So looks like if you've got a F.I. head with...

Saw this interesting engine bay at Zcon. Don't know much about F.I. but don't think this setup is totally stock.

Yes there's a sensor for the carb heater line, it's a hot=closed thermostat that attaches to the rear of the intake manifold, as described in the FSM. If the stock one isn't available, there are...

Yes, someone can. They're probably going to need to see some pictures of this car, though, something about it's history, and so on. Was it running OK with the flat tops?
What test did you do?

Kind of busy today but here's a few more.

Kats got People's Choice Award for best Datsun with his Z432.

Lots of great cars. I took about 100 pictures before the battery went dead (fortunately at the end of the show) but my ISP...

Most of the time you would be correct, the keys are usually where I left them. However, the Datsun seems to have a magnet or some other force under the seats that pulls metal objects out of pockets....

Vacuumed out the car at the carwash. What a bunch of junk. Not that I'm hoping to win a prize at ZCon, far from it. Just don't want to be embarrassed. About time anyway.

Found a magnifying glass,...

Can't see the brackets on the side of the radiator, but otherwise it looks like mine, which is the Champion 3-row from MSA. I'm using the fiberglass or CF shroud from MSA, works fine. Might have...

There's a drain plug on the bottom of the tank.

Wow. With 83 thousand miles it's still a baby.
Only disagree with one thing, cheap tires are no good where it gets to 115F in the shade, especially on the freeway, since you tend to go a little...

Loose spark plug?
