Every time I type in a search for 280Z on Ebay, a listing for one of these invariably comes up. What I'd like to know is... are they any good? Does anybody have one, or have you heard one? I get the distinct impression that they have a sort of rice-burner sound, but I don't honesty know, so I'm asking.

Hi, I have just done the diff in my 71' Zed and I have a spare R200 which has 4.5:1 diff gears (I think?) My question is what parts do I need other than the diff itself. Do I need 260z half shafts and moustache bar?? Any help would be required and vendors who could help me out in the South East Queensland Area, Australia. Thanks Luke

I have to choke the carbs in order to get the engine to run. After letting the choke off, 10 sec. later, the engine will sputter then die. What is causing this? Could the carbs be durty? I haven't touched anything on the carbs when doing the engine swap. I am very upset. :tapemouth

I need to get my E31 head reground, hardened valve seats, guides etc. Any suggestions for a machinist who knows how to do these! I would prefer Southern California area but will UPS it somewhere else if the guy is good enough. Thanks

She's a 80-zx-10thAN, Red and black. 1 of 500!!! It was working great, but I decided to fix it and in the process I broke the Ported Vaccuum switch. Today I replaced it with a new one, and it still runs like it's being choked to death, spewing this eye burning vapor all around. "****"! The previous owner put a Car-Tech Turbo on this L28, and it makes a high pitched sharp sound when I rev the engine. All of this since I broke the thermal switch!!!!! HELP FREDZED

I now have the car running and it sounds good. All vacuum hoses replaced, new NGK plugs, new valve cover gasket. I noticed that coolant is seeping from the block at the cylinder head (where they meet) near the #6 cylinder (near firewall) on the passenger side. Does this sound like a blown gasket or is this a sign of a cracked block or head? When I changed the plugs I noticed that this cylinder's plug was the cleanest of the bunch (no carbon). The car is not overheating. Any guidance is appreciated

Today I finished the final preparations for firing up the rebuilt engine I recently installed in my '73 240Z. Back in March I developed a head ache, so to speak... A white, billowy, sweet smelling smoke was issuing forth from my exhaust. I had hoped it would only be a bad head gasket, but turned out to be a problem with the head itself leaking coolant into a few cylinders. :dead: Anyway, off with the head, took it to T&D Auto in Hygiene, CO, a fine Z focused shop. Sure, they could replace the head, but they said I should bring the engine in, too. So, about a month ago I picked up the rebuilt engine. I was still working on rebuilding the rear suspension, so the…

I live in Las Vegas since ten years and it is the first year I have real problem with fuel evaporation. I always fill with premium. The engine temperature is normal. Ater a drive, I park the car for ten minutes and I am not able to start back. After a wait of 30 minutes I succeed to start the engine with effort. Yesterday temperature was 113F. Any suggestion to fix the problem? Is there any emission control parts that would need to be replaced at 88,000 miles lthat could be related to the problem?

Hello Everyone, Well, I finally, after much research on this site, decided the exhaust system I will be running on my 280Z. The set-up: 2.25" exhaust tubing 18" Summit glasspack as a resonator dynomax utra flo oval mufflerhttp://www.dynomax.com/ultrafloweld.stm stock manifold (my engine is stock BTW) I chose this system because I want my car to be :devious: loud :devious: but not send my neighbors scrambling for their shotguns when I go to work in the morning, or cause my car to sound like a rice rocket. My question is this; will this set-up provide enough backpressure for a stock engine??? The reason I ask this is because while the dynomax I wil…
