Mathew, Are you asking about gains from boring a stock L24 block? If you are, there aren't going to be any! Admittedly there will be some small gain but it will be negligible. Not worth the cost. Also does your $150 increase in building cost include the new pistons and rings? That seems kind of cheap for the machine work and the new parts... Now increased compression will help but the small over bore not so much

The car is fixable if someone is properly motivated. I fixed a 330Ci for my wife's daily driver a while back where both rear quarters were buckled. Put it on the rack and they both pulled out. You would need a good frame man, a quarter and a tail light panel...As it sits the car is worth what someone will pay for it. I have seen Z's selling at the salvage auctions for $1,500 - $3,500 for really nice cars with lighter hits...

I would agree the car is probably in the mid teens maybe a little more. One place to look is Ebay in completed auctions. Look for cars that are in similar condition to support your valuation. I agree with Pop's her insurance is going to low ball you. A lawyer might be necessary

If you have a good fitting open end wrench get a short section of pipe that fits over the other end of the wrench to increase your leverage

What are you asking for the car the way it sits? Is it at a salvage auction?

If you look down the hole, the crack seems pretty deep and if you look closely at the head the crack seems to run between the two holes. The welding questions is probably better for the shop who will weld it

I believe Chas rebuilt one... @EuroDat

This is true! Although I would think a $233k boat has a locked area at least as secure as a Z... although nice Datsun's are now trading at $25k, in 7 years they will be pushing double that if things don't change. I would think easily stolen, $50k cars would be appealing to someone who has a way to ship them overseas...

If you get the TSB's scanned I suggest you download them to the resource area of the site. They will be available and backed up that way

I wonder if a phone or Lojack concealed in the car gives off a similar RF signal...

This was an interesting review on the device "SPOT Trace led me to believe that my boat would be safe using this device and their service. Truth is the day my $233,000 boat was stolen it didn't do a thing. Why? Because these SPOT Trace devices can be easily found due to the fact that they emit an RF frequency to communicate with GPS satellites. Anyone can buy an RF detector here on Amazon that will tell a thief if your boat, motorcycle or car has one. They simply find the hidden device, turn the device off or remove the batteries and your car boat, truck, or motorcycle disappears! When we told the police officer taking the report we had satellite tracking on the boat he said those are worthless. A thief who knows his trade will not let a tracking device like SPOT Trace get in his way. SPOT won't tell you this. They lead you to believe your vehicle is protected. That's not always the case. SPOT Trace is no deterrent for a professional thief!"

Lots of 1 star reviews this one only has 8 reviews but they are all pretty good

Glad you found it

I had thought about doing that. I hadn't worked out the details of tracking, power and service plans. Thanks for the idea...

Dennis, Is there anyone other than Lojack for this technology?

Mathew, Do you have little kids that walk? If you do, be careful about leaving things that could turn over on them as they toddle about the garage. The engines aren't very stable and they are about 600#'s or so. Think about a ratchet a strap or bolt them down. I saw the screw into the block in the later pictures but probably needs to be a little more stout. Would hate to see something bad happen...I have had them turn over...

This is possible, but I have also found that the little valves in the pump get gunked up as the fuel turns to varnish from sitting. Sometimes they stick open or closed and sometimes they move but don't seal due to varnish. I have opened them up, cleaned them and reassembled. Be careful not to rip the diaphragm!!! One thing to consider is if the car is going to sit for a while undriven go ahead and remove the battery, drain the tank and run the fuel out of the pump and carbs. Our modern oxygenated fuels don't store well

I really think something like lojack is a better idea. We have to repossess cars sometimes and when we do they just pull up with a wrecker ,lift it and leave, 30 seconds max. I think many Z's get stolen this way so the cars really don't have to roll that much. Many times they pull them up onto a trailer or rollback. Being able to locate the car is probably the better solution. Professionals would rather haul it then figure out if it runs later...

Have you thought about offering them wholesale to MSA, Zedd Saver, Zedd Findings? That's what Zsondabrain did to create enough demand to justify making quantities of parts

SteveJ came to my house and helped me resolve a similar problem. He helped me clean the fuse box in vinegar and it made a huge difference. I posted about it in my thread in the 510 sub-forum. You could check the voltage on each side of the fuse, check them on them on the back side of the fuse box. You should be able to find the factory grounds and fix them. They are adequate if they are clean.

You also have an issue on the positive side which I was also trying to ascertain. 2 volts is a pretty good drop to the rear. One day when your bored clean all the connections between the front and the back and recheck the same way. I am sorry I am having trouble visualizing your earlier description of where the splice might be Zed Head might be able to help. Clean all the ground points you can find. I don't know if @zKars hidden ground point plays into this too...

PM'd Thanks

Nissan would make splices in the harness for efficiency sake. Under the loom tape in the harness somewhere will be a small splice. They strip a little section off a wire and then strip the end of the other wire and attach them to each other with a small copper crimp. They can be hard to find. Sometime they corrode...another thing to check is take your meter and with a long lead or a long piece of wire tie the black meter probe to the negative battery post and post up your voltages again...

5 volts may not be enough to even make it glow...The 10 volts is pretty low too. What is the current battery voltage as a baseline?
