I don't really know where to start, so please bare with me. About three months ago, I sent my carburetors off to Ztherapy to re manufacture them because the rear three cylinders quit firing, and my float bowl was overflowing. I finally got them back (2 months later), installed them, did all the necessary tuning that I could without the car running (including float level), and it will only fire up if I've got both carbs fully choked. It'll run at high rpms until I unchoke it, and then it just sputters out. Turns out, (from the front) the 4th, 5th, and 6th cylinders are for sure not firing, and I think the 1st isn't because its exhaust channel on the exhaust header is th…

Hey guys...can you direct me to a thread I saw mentioned but cannot find by "Carl" on starting an engine that has not been started for six years?....I'm not very knowledgeable(obvious) but don't want to mess this thing up. 1978 280z ran well when parked...the plugs and wires are new and a light weight oil sprayed int top of cylinders after last run...have new fuel filter and will change gas...any guidance is appreciated!

my 260 came with an n42 block, n47 head, aftermarket headers, 4-screw roundtops, n36 intake and balancing tube, and i think the air cleaner box is from a 260. the air pump has been removed, the water inlets are not connected, egr solenoid is gone. and near as i can tell, the check valve and opener control valve are gone too. most of the plumbing has been lost/cut/removed and is no longer needed, so there is a collection of open ports on the back of my air cleaner. but there is a nipple extending from the top of the float bowls. should these be connected to something?

I'm going to replace the motor in my 77 Z with one from from an 83 ZX and I'm trying to figure out what parts I should use from the 77 and which parts I should use from the 83. Two of the specific areas of decision making are the intake and exhaust manifolds... The 83 intake manifold is webbed while my 77 is not. Anyone know why Datsun started webbing the intake manifolds? Is that for heat? Strength? Something else? Given a choice, which is better? The 83 exhaust manifold has an O2 sensor while my 77 does not. Are there performance gains to be had by switching over to the ZX fuel injection controller that uses the O2 sensor or does it not really matter? Basically I'm try…

Hello All, Well after searching the site I still cant find an answer to my question so I am going to post it. I have a 72 Type B 4-speed. I have to replace the 2 side bushings and the 1 bottom bushing. The Fische I have doesnt show the bent shaft shifter at all. Does anybody know if the part number for the bottom bushing is 32861-24900 or 32861-N4200 ? Or are they the same? Any help is greatly appreciated!! Thank You, Jeff

I have an opportunity to purchase a T5 transmission from a 90s mustang very cheap. I was wondering if it will fab into a 72 240z with the stock L24? I'm looking at sometime in the future going to a small block V8 but not soon. I'm wondering about what bell housing I need and will the shifter be located correctly?

Hey mates This past evening I changed the plugs out in my Z as she was running oddly rich and rough. This is what I found. Can someone elaborate on why my plugs are orange? They are a bit cooler (5 on the heat range) but I'm wondering. Thanks Jan

Mates I know this has been discussed before but I can't for the life of me find the thread it was on. Is there anything wrong with running BPR6ES in Zs? Thanks Jan

Hi Folks, Quick question for ya all... I started working on my 71 z the other day.... It's been about 5 years or so since I last drove it, When I put it under the car cover the Z was drivable, but when I went and started it up the other day and pressed on the clutch... the peddle went straight to the floor board with very little pressure needed... I checked under the car, and I saw no signs of any fluid leaks.. I checked the clutch cylinder and it was full, I'm planning on bleeding, and replacing the old clutch fluid tomorrow with new.... but I was wondering if anyone knew is it possible for either the clutch main, or slave cylinder seals to leak from sitting so long and …

Guys Ever since I bought my Z in 2009, it seems that everytime I do an oil change the car will be noisy for the first week or so afterwards. By noisy I mean I can hear the chain rattle at idle and when I let off the throttle. I originally thought it was the chain and replaced it - about two years ago - but it didn't really change anything. I'm going to take the front cover off in the future to replace it, but I wondering if anyone has any ideas of what this could be and why it does it after oil changed. Thanks Jan
