I'm going to replace my valve stem seals on my stock '73 240z. I'm sick of that grey cloud behind my car when coasting down hill. Besides the seals, what else should I get that might get lost or break when replacing them? Also, where should I get the seals? I heard that Autozone sells them, or should i get them from MSA? Thanks

i can't get my78 280z to stop fouling the plugs. The injectors weren't getting pulse and i replaced the ECU. (thought that would solve probs)It had electrical woes not engine related(i think) but i am out of ideas. What are the common causes of carbon fouling on the plugs. It seems to be running rich but what do i know. Could it be the ignition module? Is that common? I just need a place to start over with.

Hello! I'm trying to get a bit more performance out of my 240Z. It's a 1972 model, and I want to go the "old school" route (not turbo, not EFI). You can check out pics of my Z at my website, just to get the picture (pardon the pun): www.angelfire.com/pro/240Z I was thinking triple weber DCOE40's (which are legal in my country, no problem!). I even found what looks like a good supplier for a full kit with linkages, anti-vibration mounts, and even a cold air box! But the PRICE! Woah mamma!! Check out the site: http://www.racetep.com/ztripdcoe.html Anybody have suggestions on reliable triple carbs for a decent price? Cheers!

I have twin weber dgv's on a 73 240z with a 2.5 exhaust. The carbs are not tuned really great but they are the best I can get them. Is there only one screw on DGV's? When I accelerate hard from anywhere around 5-10 miles an hour I will lose all power right when i hit 60 usually right when i shift to third gear. The engine just kinda makes a vrrhhhhhh sound when i try to give it gass, it will slowly rev but wont have any power behind it. I just have to let it sit there while i coast and wait for it to regain itself, then it is fine again. I dont know the psi to the regulator, but i only run an electric fuel pump and there is some type of fuel regulator there (no psi…

Parts are very rare over hear in the uk. Thanks...

Just completed the installation if my rebuilt L24 into Bambikiller and I seem to have a slight problem. I attempted to prime the fuel and oil system by spinning the engine with the starter motor while the ignition is disconnected as I have always done, but I'm not getting any significant reading on the oil pressure guage. Also, when I pull the valve cover it doesn't seem that any oil is squirting onto the cam from the cam oiler tube. Everything else seems fine. Any advice from you experienced engine guys will be appreciated. Thank you!!

Lookin at buying a 78 280Z. I'm not hofay with the 280's and my MSA manual is somewhere in the garage...different story there. It is a fuel injected, 5speed, R200, 14" and a set of 15"s, electric mirrors. How rare are these? How many of the 280 panels fit onto a 240? Is the wheel base longer? Is the FI a better option that to run carbs? What is the availability of FI components? If you change the cam to a stage 1, will a injector upgrade be necessary? The car also comes with a L20 engine and as many bits as I need from the old car. What heads were on the L20's historically. Sorry for all the questions but the car is in the North Island which is some 600 miles away and a 3…

My 3 core radiator has developed a slow leak (where it was repaired once before), so it is time for an upgrade. Has anyone bought an all aluminum crossflow like Griffin that was an "easy" fit? I have some fabrication ability, but don't want to reinvent the wheel. Looks like Griffin has one that is 26 X 19 that might work. Garrett
