The question is how to detect a failing thermostat. My 72 Z has all the goodies for hot climate (100-118F) including three rows radiator, fan shroud. good fan clutch and 160 thermostat. Also my vapor lock is fixed with the addition of an electric fuel pump.(car is full stock) My engine runs cool with the A/C on in traffic or highway but since a week I am wondering if my thermostat is showing some sign of weakness. My temperature gauge is normally always below the middle mark. Now it tends to go a bit over the middle mark and comes back to the middle in traffic with all accessories on in day time. I am a little bit picky here wanting to have a 32 years old car performing …

Are there any suitable mufflers with dual tailpipes that would work on a S30 with the L28 engine besides the ones you can get from MSA or VB, but as a complete system? I'd like to get just the muffler, as the rest is new, and there's a glasspack in the middle. thx

I recently purchased this E88 complete head and noticed on arrival that the exhaust valve cam lobe to cylinder #4 is scratched (galled?) :disappoin All the other lobes appear very good.The block side of the head looks very good. The chambers are free of any carbon or deposits This head was rebuilt 2,000 mi. ago according to the seller. My question is: Is the cam trash or is it usable? :nervous:

My new 280Z 1 2

Hey everybody... my first thread! I just purchased a rust free 280Z out of Texas for $1500. The body is in phenominal shape, but the car has been sitting in a garage for a number of years. I plan on the every popular 280ZX built turbo motor swap, but would like to get the existing 280 FI motor running in the mean time. Here are the things I'm considering doing to the car to try and get it going: - Drain all the old gas flush all the lines (where can I take old gas???). Check for rust in the tank and have it worked over by a radiator shop if it is rusty. Replace the fuel filter and fill with new gas. - Check spray pattern for injectors (is there a "how to" on this …

Well I finally got the top half of the engine apart and here is what I have found, (so far). Well first of all I broke of one of the head bolts eeeek . Then I found that the #5 injector tip was cracked. The exhaust manifold was cracked right down the middle, the exhaust stud was broken off (not by me). And I also took the intake in to have it bored out for the new throttle body which is going to cost 200.00. And I always wondered why my car ran like s--t, now I know. Well tomorrow is half off at pick and pull so I will be heading down there to get an exhaust manifold and a head bolt and whatever else I need for the 5 speed swap. My question is what type or year Z i…

Well, I went to move the Z out of the garage and when I pressed the clutch down it has no pressure. No resistance what so ever. It has plenty of fluid - which looks like it should be changed. It gave no warning, she sat for a few days and now this. Master or slave cylinder is the question? My guess would be slave. Any other ideas? Nate

Just re-united with my Z after 2-1/2 years and while checking the fluids I noticed the top cover on the plastic cap on my clutch master cylinder is separating from the side. It's about 1/3rd of the way off. Is it dangerous to drive? Where can I get a replacement? Could I Super Glue it?

Can anyone help me to understand what year and model (2+2, turbo, N/A, etc) cars came with what block casting and head? I thought I'd seen that info somewhere, but have been looking for days with no luck. Is there a matrix or something already put together. I bought a '73 AT 240Z and thought I'd find a donor car since I want an L28 and a 5spd. I will probably want a lower rear end also. I may build a stroker motor and the consensis seems to be the F54 block is the ticket. I'm not sure which head or what year cars have most of the parts I'd want. An 81-83 NA 5spd would have the tranny and rear end, but I'm not sure about the block and head. Well, I'm rambling so, if you ca…

My fuel pump seems to have quit pumping fuel. I tried to get it to pump fuel into a jar and it was bone dry. I disconnected it from the gas tank like to test if it was sucking and it was pretty weak. I took it apart and everything inside LOOKS to be fine :disappoin Any suggestions on where to go? I was thinking I'd try that RX-7 pump that has worked for others, but my local junk yard was no help there. I also found this little pump, but I've read it is reliable, but loud. I don't know if I want to spend $50 to find out if it's too loud. Or maybe I should spend a bit more and get something like this ? :stupid: Matt
