Hey Jeff - you’re not lazy - you’re very clever using your original rear shock mounts as a jig for the welding job 😜
Perfect stance, it makes the world of difference 👍🏻
Height adjustment a lot easier than the rear torsion bars on the Porsche!! Your neighbors must get a kick out of looking out there window and wondering what you are up to, "Look Marty Mr. Jeff is out there beating his driveway!"LOL
Haha, Jeff has lost it again ;)
Eibach Springs Will Probably Still Allow 16" Rims,If That's What U Have,That's What My Mech.' s Son Has On His W/ 16" BOYD CODDINGTON Rims.Handles Like A SCCA Race Z !!!
My uncle worked on the east African rally team. they gifted him the car a few years later. Ended up his garage for 15 or so years in the UK. He eventually gave it back to Nissan, who fully restored it, now its sitting in a museum somewhere in Japan. He then went to work on the R34, so sick. i wish i knew the significance of the car when i was 4, to persuade him to keep it but, there was only so much i could do lol.
That is very cool. Would have been a great legacy, but in some ways restored in a museum is the best way to make sure is can be shared by everyone ;)
I badly need to do this for my 1980 SA22C. Great work. I really love watching this restoration coming together the way it is
4:10-I believe it's not uncommon to fill the strut with oil to help keep the shocks cool by absorbing heat (transfer) etc.. so it's likely smelly old oil in there. :D
Yep, it is the same for 1st gen Rx7s. You need to fill the gap between the shock and the housing so that the heat transfers and doesn't cook the shock.
That stance is spot on! Great progress, keep it going!
She's looking the bizz now, Jeff!
Nice work, cobber.
Remember the olden days when you did not have a lift for this kind of stuff? Also, when you started using your deadblow hammer to get the second shock out, I was thinking, "He is going to need a bigger hammer". Did not disappoint ;)
When in doubt, use a bigger hammer :D
OK Jeff, it's got wheels and a motor. When do we get to see it's maiden voyage?
Can't wait to see her on the road! I went the messy route and cut mine with the shock still inside lol. I had someone else weld mine on but cutting was nerve racking.
Mate! I said this on insta but looks brilliant! love the ride height. I didn't realise how much work went into it. Keep up the awesome work!
Very good to see you use some home grown Australian suspension , Murray Coote Automotive ( MCA ) .
Murray is a legend in Australian motor sport ( Rally ) . So he knows and builds his own suspension .
Fantastic job. This is my favourite 240z!
Looks great Jeff! Can't wait to here her start up!
What an amazing job you’ve made ! It looks terrific !!! Waiting for hearing the engine roars 😉
Looks really good Jeff! This also reminds me I need to do the struts on my daily.
Haha, i laughed my ass off when i saw the notification for your video. Im literally waiting for my strut inserts to show up today so i can do the same thing on my 510. Speaking of, next build? 1600? Yes please!!!!
Looks great Jeff! Magnus Walker uses long wheel studs on his 911s and that detail would add just the right amount of race pedigree to this build.
I do have to change over the wheel studs so possibly.
Man! You’ve got a good taste in cars
Looking awesome Jeff. Keep up the great work. Can't wait to hear brum brum noises 😜😉👍👍
As I'm busy dismantling the suspension on my 911 right now I see this as a great opportunity to renew parts which are the better part of four decades old... And of course, throw in a few improvements ;-)
You don't want to explore that option on the 240Z at the moment then?
Of course, my car was only supposed to be off the road for a few months, before the "while we're at it" bug caught me... So I guess I can understand the desire to "move on" quickly...
Perfect height!!! Good for you!
Looking better and better...
Best way to check the test-weld is cut it to get a cross section view of the penetration.
Definitely, these welds are just to stop it falling off under rebound as opposed to taking the weight of the car. Even if they were holding the car, I am very confident of the penetration.
Home Built By Jeff The caveman style, bash it on the ground, test is much more entertaining too.
That looks fantastic!! We done. BTW, I dont think its laziness, I think it's working smarter VS harder. l
🔥🔥🔥 Well done! That looks sick!
Jeff, I would suggest putting anti-seize on the collars and where the strut threads into the lower mount. I made the mistake of not doing that with the coil overs on my 260Z and am now paying the price several years later.
To be on the safe side, always remove the shock insert bottle, or in your case the bottom sleeve/tube only, when welding anything related to coilovers, even if its only oil and no gas shocks.
I was hoping to watch you pull the rear spindle pins! It's a rite of passage for true zcar guys!
Not if I don't have to at the moment ;)
I bet you said, “should get it done real quick,” on that second shock.
Looks brilliant love it
Love it,the car looks awesome
Looks just right👍
Ride height looks great! When you did the rear, you said you were being lazy because of your way of completing the job. Don't confuse being lazy with being efficient.
True.
Great job Jeff - love the set up!! I was gonna say you had a shockingly good day, but you must be sick of my dad jokes by now.......................... Tiger.
Never! Dad's jokes are the highest form of humour ;)
Hi Jeff, I have been catching up on your vids and love them. That Datsun looks magical. Anyway you mentioned something about going out on the Track? I usually attend a great club to have a bit of fun out at Wakefield and would encourage you to come check it out.
Job well done Jeff even the lazy part. I personally think it wasn't lazy more over I would say smart,
This is awesome! It looks great.
Excellent video 👍🇨🇷
"lazy" is one adjective I'd definitely NOT use to describe you and your work ethic on this project!
Looks perfect!
Looks awesome!!!
The car looks very nice. I like to decorate your car very much. Follow every clip
2:55 have you been rolling on the dogs mat Jeff? 😂
awesome! nice short cut on the rear struts looks nasty at that height,
5* work. Looks awesome
Very nice ride height.
Looking very nice 👍
great job 👍🏻 sits nice
I hope you didn't ruin the rear wheel bearings by putting the ground clamp to the wheel stud. Running welding current through the bearings might harm them. I wish they ok :) btw. Superb channel!
It could have messed them up now that you mention it. Time will tell ;)
Jeff. I think your suppose to install them flush at the end where you weld.
They have internal stoppers, so that is where they are supposed to be ;)
Lowering the car is secondary to getting the p-car running. LOL
True ;)
Hey mate just a question when you take your cars back to bare metal what do you spray them with first before high build primer
If it helps - We're now using epoxy based etch primer, or epoxy primer. Good stuff, you can also work over it, unlike etch.
As M or D said, epoxy primer first.
@@ModifyOrDie I have used Self-etching primer on bare metal many times followed by a good layer of epoxy primer and then sand just the 1 or 2 layers of epoxy primer before starting my colour coats.
Stance looks great, but you still need a couple of "Y's" for that lift. Get on that mate!
?
Cracking nuts and bash/dent the beejeezeeus out of the shaft sounds painful....New coilovers worked out well.
Wow, that second insert was proper in there! Do you need to get those welds certified? Here in NZ I would need to have those welds done by a certified welder and signed off to make it road legal.... good work!
Yes. The kind of job that really does need to be done properly too.
If only welding on a threaded collar to a strut it must be welded top and bottom by a capable welder."or words to that effect"
Its covered under the general welding in the Low Volume guide.
Any more than that yep ticketed welder, with crack test report, whole nine yards.
Just been through it all on my 1600/510 build.
Yes I would say it does need to be certified, but you also have to remember that it is not holding the weight of the car. It is basically only stopping it falling off in rebound.
A threaded collar being welded to the strut is holding the weight of the car, so it is much more critical. This is not.
looks great jeff, ride height looks spot on,
what's the name of the music on this video, it's in my head now
It is in the description ;)
What size wheels do you have ? Specs ?
You mentioned you had an R31 many many many videos ago, what suspension did you put in that?
I never changed that. It was a JDM R31 pillarless GTS. I handled like a boat :D
They’re cool cars, in my friend group from school we have about 5 aus delivered R31s and 1 passage.
MCA, where have you been?
What size shocks were they I just got myself a 280z 76! Need guidance!
MCA
Did you turn the wheels from side to side to check for scrubbing.
I did, and so far it seems like there is heaps of room.
Love that car! Only issue, there is no aviliable Datsun 240Z in Czech republic for reasonable money :( :D
Not reasonable here either ;)
Nice job :D
How much was the coil over kit? Thinking of doing it to my z.
Contact MCA for a proper quote mcasuspension.com/suspension
wont the heat melt the seals?
Any seals were a long way from heat.
Do a pov when it's running
😍😍😍
Great video as always! Is the coilover bottom part stainless steel? Did you just weld with regular mig wire or used something special?
I believe it is not stainless, so I just used mild steel wire, and then rust treated it.
Get stance!!😊
Car vs caaa, who would win?
It would be a draw as here they are the same thing ;)
Looking at your flare mounting at 11:22, are the 'washers' countersunk type like the screws?
Think you might need button head screws and the appropriate finishing washers
Eg, www.essentracomponents.com.au/images/stories/virtuemart/product/SR1946_1.jpg
It looks like you have Type3 screws with Type4 Finishing Washers
No, they match as far as fit, it is just that the washers are gloss where the bolts are matt.
Looks like a lot of castor on the front wheels, looks a bit odd having the wheels sitting so far forward in the arches
does it pass the coke can test
bump steer?
Not sure how much lowering it changes it, but it is still the original geometry.
@@HomeBuiltByJeff If you're looking at the front of the car while on the ground and see the front control arms parallel to or angled higher than the front crossmember inner mounting locations, then you should consider roll center adjusters to correct the geometery. This is a common occurrence on lowered Z's and can greatly affect drivability. One fix for this is to use an aftermarket front crossmember such as ApexEngineered or to drill 1/2" up and 1/2" out from the stock inner control arm holes, weld in a new inner washer, slightly modify the tops of the control arms for clearance and you're golden.
Australian standards pretty loose for modifications? Welded struts require non destructive testing and an engineering cert here in NZ. Bit sketchy doing it on the car and not knowing how good the welds are.....
If you EVER expect to take this car to the track, you CANNOT have drum brakes on the back. Just saying, you're going to have to do a rear disc conversion
It may be something I do in the future. Getting it on the road is my first priority ;)
I understand. @@HomeBuiltByJeff
That's odd as many of the competitive vintage Z racers still utilize the rear drums with upgraded shoes. Most rear disc conversions for the Z screw things up badly, they tend to throw off the brake bias so much that the rears don't bite enough.
Mr. Datsun My apologies, I had no idea. My experience is mostly with old BMW’s & GM’s and they end up turning into mush after a couple laps
Remember the car will settle over time, so the car might end up a bit lower than expected
Absolutely. It is good that it now will only take 5 mins to readjust the height if necessary ;)
Ride height isn't going to be a legality but fitting coil overs on a registered car probably will
I was going to say "starting the car", but I was wrong.
When are we going together those drums replaced, they are hurting the greater good.
Hey Jeff have you been watching too much B Is For Build because you did such a hack job on that rear suspension install 🤦🏻♂️
It is definitely not 'hacked'??
couple cm lower on the back and it will be perfect)
I like it level ;)
