I was wondering how hard it is to get the intake manifold off on a fuel injected Z, my intake is leaking and in need of a new gasket. I was looking at it earlier and it looks pretty rough getting in there to get the bolts off, is it attached to the exhaust manifold also. Let me know what you guys think and an easy way to get to those bolts. Thanks

I just picked up a 280zxr for hella cheap but it has two problems, I need to replace the door hinges to the driver side and it needs tranny work. Do any other Z cars Tranny blocks match up to the engine of the zxr or do I have to go through a dealer, also I can just tear the hinges off of another old 79 280zx right because the bodies are the same besides the spoiler?

My 72z has a later model engine and I'm not quite sure how to find out just what year the engine is. I know of the numbers stamped on the passanger side of the block just under the head and I've heard there are also numbers near the engine mount on the driver's side. Does anyone out there have a link to a site that will help me figure out what year my engine is? BTW, it has a N42 head if that narrows it down enough to ID the year. As always thanks for the help, Dan

I found this Roadster on eBay and noticed that the seller says the engine is a Nissan Z engine. It has a crossflow head, One Carb, and 2 plugs per cylinder. Could this be a NAPS-Z engine?? Ebay Roadster-4 Cylinder-8 Plug

I am planning to buy a new radiator for my '72. Have looked at lots of radiator sites and made lots of phone calls. Comming up with a wide range of prices from $260 for a 4 row to $175 for a 3 row. Any advice as to a reputable dealer? Any "best" radiator for street use? Do not need an aluminum unit.

My Z broke down today. I was driving on the freeway today and the engine was jolting and it was loosing power, then the engine stalled on the freeway. All my gauges read said that everything was normal. I pulled over, popped the hood, and looked for anything out of the ordinary, but everything looked okay on the surface. I then started the car, and it started right up like a champ. About 10 miles later the car started jolting again and I had no power. I pulled over and called AAA. The only thing I can think of is the clutch, but I am not certain. What does this sound like to you guys? Oh well, she is in the hands of my mechanic now. My Z has never broken do…

Anybody have problems with an MSA header ? I bought a MSA 3-2 coated header for my 260 and have since sent it back to them. I believe it's badly manufactured since on bolting it up the carbs(early SU's) are essentially touching the second pipe. There's plenty of room for routing it so there'd be much more clearance, like the other five pipes. MSA says it's bolted up on their showroom floor and has an 1/8" clearance with both same early carbs and an E88 head. I've never dealt with a header before, but considering the heat issues with the car I think I'd be insane to have so little space there. Has anybody run into this issue before with this header ? Has anybody seen tha…

does the intake manifold have a spacer on a 71 240z? mine has a black one about an inch thick. i have heard that you can get a bigger manifold from a 240k which requires a spacer. could it be possible that it is a 240k manifold?

Ok, I finally got some time to start working on my Z. I rebuilt the SUs and they are nice. However, I am having some trouble setting the correct timing on the engine. The car is a '71 and I am the third owner. I verified that the notch on the damper pully lines up with the pointer when the distributor rotor points to the #1 cylinder. But at idle, when I put the timing light (set to 0) on it the marks are nowhere to be seen. I had to turn the dial to 45 to line up the mark at the pointer. My first thought is that there is no way I have 45 degrees of advance at idle. It shouldn't start with that much advance. I am testing at 700 rpm and I tried with the vacuum advance att…

Hey guys, I just put a mallory distributor on my car. I like it alot. I use to have a problem of the car not getting enough gas at higher revs under continous acceleration due to a fuel pressure regulator, but this new ignition sparks strong enough to supass the old problem... ( I think thats what its doing...) Anyway, I spent about 2 hours trying to figure out how to hook it up. After a few backfires and some other noises I finally took the valve cover off and the first sparkplug and set it to TDC. I tried this before but I think I had it at TDC of the exhaust stroke... I dont know really know what the little tiks on the crank pulley are but would like to!!! I have…
