Quick note. It seems I made a bit of a mistake when putting my thermostat back on. The spark plug wire holder that bolts to the rear most bolt on the thermostat cover is made of plastic, and when I put it back on, I sort of snapped the plastic in half. Does anybody know who may have an extra?

I bought several plugs yesterday. I know one fit very nicely, threaded in with no issues at all. I will see which one it was. I think it may have been NPT. As far as the carbs go. They were installed by Ztherapy on the manifold when it arrived. I just bolted it up. I may have to remove the carbs to get a good torque on the nuts. I think a 12mm crows foot would help dramatically as well.

They do put in different needles that run more rich. I am not sure that it is part of the basic Ztherapy SS treatment, but I requested them. I get the impression that the performance in the SU's is mostly due to the correct needle selection and the weight of the oil in the piston. You can control how fast it rises and how much fuel comes out. Until you reach the max CFM the SU's can flow with the pistons fully up, I think you can tune to just about any reasonable performance level.

Thats the plan...just need to find the cleanest way to do that. Latest issue is the upper and lower radiator hoses. My factory radiator was upgraded from a two core to a three core. While this is great and all, the outlet and inlet to the radiator seems to be larger than the stock 240Z radiator. I ordered an upper and lower radiator hose from Black DRagon and the part that attaches to the engine is perfect, but the part that had to go onto the radiator was a ultra tight fit. I think its far too tight. I need to find a larger diameter tube hose, with the same bend. The search is on!

UPDATE: All parts are on the car. I did not get around to finally torquing the bolts. There is no way I will be able to get a torque wrench on the bolts below the intake, so I will have to use the force. This is shaping up well. I still have some cleaning to do on the block and run new fuel lines. Still have not figured out how I want to rerun the coolant lines. MOre on that after Turkey day I guess.

the studs make it much easier, The lower spacers and nuts are pain, but very doable.

Okay, today was a great day. I got the header back on as well as the new carbs. They look very purrrrdy. refinished my thermostat housing and cover and got those in. Found some spiffy cad covered grade 8 bolts to install there. On note of warning. Put the washer and nut loosely on the lower studs for the intake first. Trying to fish those lower nuts on with the header and intake on was a bit of a pain. Apparently I have bear claw hands, and they would not reach very easily. But after many trys and finally MacGeyvering with a wrench and some tape, I got them on. Tomorrow I have to torque all the bolts and then I can start installing my new fuel lines and reroute my coolant lines to take into consideration the lack of intake water passages. MOre to come.

I recently did this on my 71 dealer installed pulley. I removed the old bearing via hammer and socket. I bought the Gates pulley that NAPA sells and when I tried to tap out the bearingI sort of ruined it. DOH! But while it was out, I measured the outer race and it was 1.674" exaclty on the old bearing I beat out and the new gates bearing I ruined. I went down to the parts store and picked up a new SS bearing and I am back in business. I will have to go to a machine shop to get it pressed in as I am without a vice for the time being.

YOu guys are making me VERY happy! I am about to start bolting parts back up. I am holding off for two reasons. I am thinking that I may want to get some parts cad plated. I have a small pile of connectors and bolts and nuts. I cleaned them up with a wire wheel and Dremel, and they look clean and new, but would look better with a shiny CAD plate. I also nearly finished up my air cleaner resto yesterday. I have a few runs I need to work out with some 2000 grit and polish off. I think I am going to clear coat the thing when I am done to protect the new stickers I got for her. All I am waiting on now is gaskets for my Thermostat housing and I am off to the races! Should be fun. I think I will go ahead and flush the rad while I am here and replace all the hoses. I have to plug up the intake water path anyway.

Quick question I am about to start putting my intake and header back on my Z. I have cleaned everything, chased all the threads of the head with a tap and got them squeaky clean, and I am about ready to put the new MSA studs in the head. Would it be better to use locktite on the studs versus anticease. I mean it would help hold them in, and you can always heat it up to remove the locktite. I have been debating this. I actually bought a tube of anticease to use, as its my normal mode of operation, but it would be nice to not have to worry about the studs backing out. Also, the torque spec for the manifolds is 8-11 ft lbs. Can I assume both the stud into the head and nut on the stud is 8-11 ft lbs?

Actually he did. I am not being mean, I LOVE his Z. It is a true dream machine. NO doubt, the logic just does not hold up. It is neither here nor there. Just a curiosity. People intrigue me.

So just to point something out. Your into this resto for 6 figures, and you will not up the 20 bucks for a pro account.. funny accounting.. haha

Today my orange paint from Classic Datsun showed up, as well as my new tensioner pulley for the AC. All I have left to do is clean out the threads, and I should be able to start putting things back together! Just need some thermostat housing bolts that go into the head. Must be metric bolt store around clear lake somewhere!

My master cylinder looks exactly like that. With the same long bleeders, but as I recall, I did not have 1.5" of room. Its been a while, so my memory is fuzzy, but I will definitely try again when I get my carbs back on! By they way, thanks SO much for the effort in taking those pics!

THat confirms what I thought. Good info. I was going to order a new T-stat housing Arne, but thought I could save this one with a wire wheel and lots of scrubbing. So far so good. I am prepping it for paint right now. I still need to clean the holes. I am guessing I should liberally coat the next bolt with some copper grease or antisieze before installation. Something to prevent corrosion! YUCK.

UPDATE: Okay, I got a small case of the while I was at its, and took off the thermostat hosing and the upper radiator hose. I ordered all new seals and hoses, since, you know, I was there. Now here was an adventure. The bolt was so corroded into the thermostat housing the head snapped right off. OH JOY! Three hours later and some delicate tapping with a rubber mallet I got the housing to loosen it's death grip on the sheared bolt. Now with only 1/4" of bolt sticking out of the head, I had to say my prayers to the good Lord above, said a few to Budda and Allah, just in case they were car nuts too, never hurts to be thorough, and clamped a vice grip to the last remaining threads to see if the bolt would unscrew. You know many things go through your mind when you attempt something like this. You have this feeling like you know there is a smarter way to do this, but at this point your caveman instincts from the Pre Cambrian period surface and you just want to pick up the car and throw it. Long story not so long, the bolt nicely unscrewed. Thank the Lord. OR Allah, Or Budda, hell I even thanked my wife. Kept cleaning things up, put some new paint on the thermostat housing and the heat shield, and started to do some final thread cleaning on the heads. One question folks. I asked Ztherapy to block of the water passages from the intake. So the water line that does form the thermostat housing to the intake, I assume I can just plug. Also, I should be able to remove the line running around the back of the engine as well. Is this correct. From the looks of it, the coolant does not need this flow path to function correctly. Any thoughts. I have to go see if Black Dragon or MSA sells bolts for the Thermostat housing now. I love working on my car.

You know I never thought of that!

THat looks like the same one. I need to study your post to see how you got it on. THey look similar. I will take pics to see if they are identical, but I have the bleeders on my engine side just like you! Got a part number recommendation Arne? ha ha

not solid. Looks like it has a flared tip on one end. I did find a wharehouse that sells brass plugs that are flat. It would give me the extra half inch I need.

Well I am embarrassed to say this, but I hope my Z friends will bare with me. When I installed my ITG air cleaners it was a temporary fix. My problem was that after I removed my stock air cleaner, I honestly could not get it back on. My Master cylinder (non Z original part, has been replaced somewhat recently by PO) has ports on each side to facility easier routing I would imagine. My brakes come out of the fender side of the master cylinder. The plugs put in the side that face the air cleaner are too long to allow the air cleaner to be put back on. I know what all of your are thinking. If I can get it off, I should be able to put it back on. NO SO says I!!! I was able to stick a wrench inside the air cleaner and loosen the nuts on either side of the carb. I cannot even get my hand inside to start the bolts with the long master cylinder plugs sticking so far into the engine bay. So what I need are super short plugs for the master cylinder so I can get my newly refurbished air cleaner back on. Any ideas?

I need to go get mine, I do not have it memorized. Is that bad? WAIT, its in my signature line..! haha HLS30-38691

Great I just ordered one of those Gates pullys, from AMAZON of all places!!!

Paging Dr. Palmer, Paging Dr. Bruce Palmer. the experts at Z therapy on this sight are the closest things to Carb Gods we have in this country. I would imagine they can help you.

What great timing for this thread. My idler pulley on my system is screaming as well. Did any of yours look like this? Let me know guys. Wow, come to think of it. My bracket looks kind of rusty..

I wish I could tell you. The header was like that when I bought the car. I am thinking of sending it off to get redone. It is looking a bit worse for wear.
