HLS30-01121 Gets A New Life
My name is Clay and I bought a 1970 Datsun 240Z (HLS30-01121) about three years ago.  My intention was to drive it on the weekends and save up some money for a full restoration.  I am stationed in San Diego, California and found the car on Craigslist.

Z31 N/A RB project
Hello, everyone. I haven’t been on here in quite a while. My dad is a regular (diseazd) with 5 amazing s30’s. I have had many Nissans and owned a 72 510 for a few years but have never owned a Z. The S30’s are just too expensive for me and for some reason, over the last few years, I cannot get the Z31 300zx out of my mind. I almost bought one a year ago and then went on to other projects.

While removing the manifold studs on my rebuilt head to replace with new studs from MotorSports, the front one broke off below the head surface!    The one that broke was already broken to where only a 1/4" worth of thread was usable, and I couldn't double-nut it, so it had to be replaced.  The others came out okay after a good soaking with Kroil, a bit of heat, and double-nutting to loosen.  But the front #1 exhaust wouldn't budge and broke while trying to remove with vice grips.  Lucky for me the engine is on a stand, easier to work on.  I figure I'd post some pics of the Helicoil job since I didn't see one around here, in case someone else has the "joy" of doing this in the future.   I've done a few, but definitely not an expert.  Feel free to add your thoughts or tips to the thread.

Above shows broken stud.  I've already center punched it to help get the drill bit centered. 

Here was my first choice, screw extractor and left handed drill bits.  Tried 2 different sizes, no luck.  Plus I'm always afraid the extractor will break off and make further drilling a real pain, so I didn't crank on them too hard.

Since I already had the stock M8 1.25 stud kit, I opted for that size instead of going to a stouter 10M stud.  Ordered a real Helicoil kit instead of cheaper knockoff.  Kit includes some threaded inserts, a tap, and tool to install inserts into newly tapped hole.  Didn't include the 21/64" drill bit, which I had.

Carefully drill, keeping hole perpendicular to surface, and no deeper then existing hole, and centered.  I started with 1/8" hole, 1/4", 5/16" then the final 21/64".

Tap the hole, using oil to help get a clean cut.  Work tap back and forth and remove a few times to clean out debris.

Insert is threaded in using the tool.  There's a little tang at the bottom of the insert that you break off after you get it in place.

Done.  Be sure to use anti sieze on the threads when installing new studs.   I'm not sure how well this will hold up in the long run, and the repeated hot/cold cycles.  I guess I'll find out.

Hatch strut lift
Has anyone found a modern or commonly available hydraulic strut for the rear hatch? I need to open and close mine 3-4 times before it will pump up enough to stay up.

Modifying a '70-71 choke knob to fit a '72
Well, my choke knob gave up the ghost after 40+ years of being yanked on. It snapped just above the set screw.  I saw that the '72-73 know was NLA but a new '70-71 was still available, different symbole, but I figured it would still fit.

No such luck, the hole in the knob that fits over the metal tang is too small. Has anyone tride to modigy the knob to fit?  The hole seems to be deep enough but either the width or the bredth of the hole would need to be filed to enlarge the hole to fit. My worry is that it needs to be a tight fit so as not to wobble, the set screw seems to do little more than hold the knob in place.

Has anyone tried this?  Any advice?

I am back!  After selling my series-1 240z on August 21st I picked up my new 240z yesterday September 11th.  To be honest, I did not think I would be in another Z so quickly but my friend Mike Cooper, who never sells anything asked if I would be interested in buying his red 240z.  He needed the room more than anything and had owned the car since December of 2000.  I had seen the car many years ago parked in the corner of his garage but never saw it up close.  After a trip to look at it and another trip to drive it, I knew it was the one for me.  When I sold the series-1 Z I had a goal of taking the money and getting my shop air conditioned before getting another car.  The next car would be a classic Z I could modify and not affect the value.  It could be a 240, 260, or 280 as I wanted to do triple Webers, springs, sway bars, different seats, etc.  Mike's car already had all of this and more.  The highlights include a 1mm over '78 2.8L engine w/an E88 head, triple Dellorto carbs, '83 280zx Turbo 5spd w/Hurst shift and custom shift handle, '85 Turbo differential w/Precision LSD, Susp. Techniques springs, front & rear sway bars, and seats from a Mitsubishi Eclipse.  The car is a 1/72 build and is number 65,283.  As you can see in the pictures it needs a deep cleaning, the paint needs a careful cut & polish, and there are lots of little things that need to be addressed, mainly just items that need to be replaced due to age.  The car was originally silver with a red interior and one day it may return to that color scheme.  For now, it will be tinkered with and driven alot!  When I first saw the shifter handle I thought I thought it looked a little ridiculous but I can testify it is totally functional.  It puts the shift knob right where you want it and the throws are short and precise.  I will keep this post going as I make updates and repairs.  I look forward to showing it to everyone at local events in Austin and at Atlanta in October 2018!

And it came with a few parts too!  Believe it or not 99% of what you see was packed in the car when I picked it up.  Who needs an SUV?

Project Boondoggle (or, so I went and bought a Z!)
I've been lurking here and some of the other Z boards for a while, and after wanting a project car for basically my entire life, I finally pulled the trigger a couple weeks back so I guess it's time to join; hope y'all have room for one more!
So here it is, my new 1978 Z, as it looked when I brought it home:
I scoured CL for a while and any reasonably-priced cars were getting snatched up in hours.  I checked out a handful of cars in my desired price range and 
they were all projects well outside my budget or capabilities, so when I found this one I jumped on it.  It looked pretty good, and I knew it would be some work, but have uncovered some unexpected surprises in the last couple weeks.
The starter died when I brought the car to the shop so someone more qualified could take a look at it. It failed smog with an illegal cat, gross polluter numbers and an EVAP leak, and almost every nut and bolt I take off has revealed some bodgy-at-best repair work by previous owners.  All part of the fun!
I have a lot of plans and a whole lot of work to do, and I sure am grateful for all the helpful folks who have already walked this path before me.

Thinking about installing an BMW M6 engine in my Z
I have a 1987 M6 that I have dumped thousand$ into but there is no market for them at the moment so instead of selling it for 30 cents on the dollar I was thinking about keeping the freshly restored S38 (inline six 24 valve, dohc) engine an 5spd and part the rest the car out.
I've done the measurements and it will fit nicely into a Z.
What do you guys think?
Would I be creating too much of an odd ball?

Hi all, I need reminding please of what the threaded holes are for marked 'A' on my 1970 240Z differential mount . Also, am I correct in saying that the small steel plate marked 'B' goes between the mount and the insulator - it's been some time since I dismantled it but I'm pretty sure it does. Thanks

"So honey , I bought another Z today" 

instant response ," you've got to be fu@£NIH kidding me "

Anyway, didn't see this one coming but it's landed in my lap. # 4858 , 5/70 build date. Still not even to my house yet and I've spent a total of 15 minutes looking at it.

Too many unknowns to answer anything specific , but it's definetly fixable . Actually in pretty decent shape- respective of its age. 

Update this when I get it home .

Hi everyone! My name is Mark and I will be restoring my 1976 280Z coupe HLS30-271295 starting this year. I look forward to your feedback and help as I am sure most of you have a lot of experience with restoring your own cars! I am hoping you will all chip in and help me avoid some common pitfalls and mistakes along the way.
