Can anyone out there point me to a supplier of the R-180 Quaife? It's time to pony up for a second/backup. Motorsport Auto doesn't offer them any more. Do I have to go to the factory to get one? Thanks. PS See what I can afford when I don't crash the car!

Where can i find info on the pressure valve and how to adjust it properly, and the person who put this car together put the vacc/boost gauge feed to the intake and all it reads is vaccum and does not go over the 0 mark

I am the new owner of a 78 280z....ok..ok it's a 2+2, but I had to get back into a Zcar. It's not perfect but it's got a solid frame and rails - which is rare in Missouri. My problem is that the accelerator sticks. I am able to pull the pedal back and it's fine. I have lubed everything but I think it might be the spring at the end of the rod (i think it's actually called something else). I haven't picked up a book on it yet, but I thought I would check with the experts first.

Hello all This past monday I took my tank in to get fixed as it has a crack. Before doing any welding the place cleans the tank thoroughly to get all the crap out. (as one would figure gasoline + fire = boom). So I though cool I'll get the thing back Tuesday throw it back in my car and be done with it. Today around noon i get a phone call from the guy that works there saying that with the amount of crud and gunk in my tank, it will take him longer to get it cleaned then expected. I agreed and told him to let me know when it was done. When I was taking the thing off the tank did seem like it was pretty filthy inside but didn't think it was that bad. So two questions for yo…

Hi all. I replaced the clutch master and slave cylinders and now have grinding in all gears, including reverse. It's a '76 280 with a new 5-speed installed (original was 4-speed). I searched and found several posts about this problem but think it's not an adjustment thing. The factory manual says the stroke on the slave should be 1 3/4 inch but I'm only getting around 1 inch. Checked pedal travel and freeplay and they're all good. Also added a short spacer between the slave rod and the clutch lever but it didn't help much and I'm concerned that it might cause the bearing to be constantly engaged. Bled it many times, of course. Seems that the stroke is just too shor…

What could i do to refurbish this exhaust manifold, is it even worth refurbishing, i would imagine finding a new one of these would be extremely hard. Any thoughts? I know i could buy a motorsport header, but i like the way this car sounded when i acquired it.

My '77 coupe has been having some seroius overheating issues lately. I'm afraid it may be the head, but I'm hoping is something simpler and less expensive than that. I bypassed the heater core since I don't have the money for it at the moment, and it ran well for a while with water in the system. Then I put coolant in the system(pre-mixed). I did make the idiot mistake of not watching the temp gauge due to the new coolant, and the lower hose blew. The needle was past 250. I pulled over immidiately to let it cool down, and got a ride to a near by Autozone to get new coolant and a new lower radiator hose. I also got a new radiator cap and thermostat. Once everything was pa…
