A failing TIU can often be temperature related. Mine would work great when cold and started failing after driving for a while. It did start doing it once in the garage before I wanted to leave. That...

How old is the master cylinder. The reason Im asking is old master cylinders don't like being pushed (pedal) to the floor.
Over time the section of the cylinder that doesn't get wiped clean by the...

Something freaky about the forum. Double post and can't edit the second one

I agree with zed head. Sounds a lot like bad module or a short to ground in the negative (blue) going to the coil. It looks like you are narrowing the problem down.
Good luck with it.

Yes, I have the MSA fibre glass bumper already fitted, but still using the 280Z valance. The problem with that combination is it leaves a rather large air gap between the bottom two row grille and...

Ic you are changing the pinion, you should replace the o-ring seal on the pinion adapter and the lip seal in the adapter. Don't wont to go to all that trouble and have it leak afterwards.
If you...

Your project is coming along nicly. Really looking good. Nice job on the lenses. My taillights were just as bad and the chrome bezels were painted black by the po. I have a set of 240Z lenses for the...

If the coil tests ok and it turns out to be the TIU in the dizzy there is a write up in http://www.classiczcars.com/forums/tech-pubs-howto/51102-gm-hei-module-install.html#post446171 on how to...

Hi Tamo,
Nice mod and good clear instruction. Looking forward to seeing finished/installed pics.

Do you have the specs for the CS144?

Cheers Chas

Hi Chickenman,
Im using genuine Nissan filters to the best of my knowledge, but the Datsun 280Z was not in Europe so the Nissan dealers here may source their fuel filters locally. I would have...

I managed to take a couple of snaps of the bumper mounts. Mind you its on a 280Z, so I imagine it will be a little different on a 240Z.
The slotted mount for the front two mounts should be centered...

Hi Cliff,
Ill try to take a threw photos from behind the bumper later tonight and post them. Give you a bit of an idea what the brackets look like.
Chas

I have one on the fornt of my 280Z. I bought it in Feb 2014.

Positive:
Fitted well. Did need a little sanding on the inside line to match passenger side valance.
Mounting brackets are slotted...

Next time it does it get someone to help you check for spark at one of the sparkplugs. It could be your TIU failing when it warms up. Mine was doing something similar.
The TIU is behind the kick...

Thanks for dragging this thread up Tomo. Forgotabout it. Good reading it again:)

My 280Z has been going strong since I made the HEI mod. Certainly better that the old tiu. It revs to 6000rpm not problems even under full throttle. I don't go about 6000rpm so its good enough for my...

The IC's I have played with generally don't give problems when cold, but Zed Head said is a good point. They need good voltage to work. If the voltage drops off to much they will stop triggering. You...

-The 240mm clutch won't bolt up to the maxima flywheel. The dowl pins are in the wrong position and the 240 uses 9 bolts to hold it in place.
-The maxima flywheel is the first generation after the...

If you go with the 10lb Fidanza flywheel and you are still worried about the oem slipping you could use the 240mm from the 2+2. The pressure plate is about 4lbs heavier which means a totoal weight...

If you are looking for a flywheel. Check the weight or get the seller the check it for you.
The Maxima used a +/-18lbs, the Zeds all used 23lbs and the trucks used a 29lbs flywheel. They all look...

I did mine with a HEI module in the TIU housing and a Petronix Flame thrower II (0.6 ohm) coil. Working perfect since day one. Very happy with it. You sure you wired it correctly? If its under the...
