I need to figure out what gears I have in my car. My speedo reads wrong. I've got the 5 speed with the big gap between first and second, and I think the original rear end. My gas mileage is a nightmare, though, so I'm not too keen on gears. I'm hitting almost 13 mpg now after tuning my carb and adjusting my timing. I was around 9-10.

Tried it again, it works now. Just a weird bug I guess. Thanks RB26.

That's exactly how my setup is. I drove from Miami to Jacksonville (400 miles) right in drone central.

I like it! That must be pretty damn loud, I'll look into it, thanks Tony. That might be pretty cool, but that would definitely ruin my paint and not be very reversible. Are they noticeably louder? I went for a single because of the weight of extra piping. I shed quite a few pounds off my car.

HybridZ, please, just take my money! So, I'm trying to donate to HybridZ, log in to my paypal, select my card, and go through the steps to send the payment. Instead of being redirected to a page that says you guys got my money, I got this error. I tried a second and third time, and instead of asking me my card info and everything like it always does, it takes me directly to this. What can I do?

I'd love to just test it like that, but that means I'd have to cut the muffler off, it's welded in place. I'll make a thread if I do modify my exhaust some more just so people can have a listen. Lots of people say the same about the loudness, and I agree that it is plenty loud, but I like a really loud raspy sound, which I think I'll get from straight pipes. The car does get loads of attention from the police, but they're really friendly up here, so I've had no real issues. I was parking in my university's garage, and the exhaust resonates a lot in there. One of the university officers pulled me over to tell me that I was setting off all kinds of car alarms and to try to not be so loud. We then proceeded to talk for like ten minutes about the car, popped the hood and everything, while his car was idling behind me with the lights on lol.

My current setup is a MSA 6-1 header, followed by 2.5" mandrel bent pipe with the least amount of bends as possible, when then goes to a Magnaflow muffler and that's it. This is what it sounds like now. I'd like to go louder. Is there anything more I can do, or am I going to have to get rid of more bends and shorten the exhaust? I'm trying to find a Z with straight pipes, but I can't find one. If one of you guys has heard one run, how do they sound?

You just saved me a huge headache! Thank you! I haven't, there are so many gimmicks on the market that unless I've heard about a product and it's commonly used, I tend not to trust what the label says. I'll look into it, though, thanks again. Also, I did some poking around earlier, discovered this on the other side... And then worse... I'm trying to find a good deal on a compression test kit since I'm pretty broke at the moment, I'll update once I get some numbers.

I've got coolant mixed in there. My engine started to make a clicking sound, so yeah, it's time for a valve adjustment. I picked up a feeler gauge when I went to get a plug gap tool knowing I'd have to do it soon. It's very possible the previous owner put a new head gasket on, he did a lot of engine stuff and never drove the car. I need to get a better torque wrench. Today's my day off, I'll pick it up after I'm done getting my tires installed and give it a try. Hopefully that takes care of it. Now that you mention it, a blown head gasket wouldn't be too bad. I have Friday off every week and don't have school until 3 pm, which gives me plenty of time to take care of the maintenance. I've got a Holley 390 (no carb heating line) and no heat or AC, so there's not really anything to check. I've never done a head gasket (and I've dreaded it in the past due to my inexperience), but I'll get to watching youtube videos and give it a go next weekend if that's the issue. Thanks a lot everyone for your help and input.

Update: These spark plugs are three weeks old, correctly gapped (of course), and have about 500 miles on them, tops. Disregard the numbers on them, I messed up. I didn't know what where cylinder 1 was, so I just started from left to right, standing on the passenger side. Plug number 5 (which is actually number 2) is wet with what seems to be oil. Plug number 4 (actually 3), is a little wet as well. They're only wet around the threads, but the tips are good (probably because the engine toasted all the oil off them as it ran?). I checked number 3 as well (really number 4) and it was moist as well, but not as much as these two. Could someone provide some insight about possible sources of oil?

I'll give them a check, just for safety. I flushed the radiator no more than 2 months ago, which was about 1500-2000 miles (tops). I also changed the oil the same day. Oil was black was a bit black and nasty, coolant was fine. I'm about to change the oil again, as its already black and nasty, even though I've topped it up with a full quart since the oil change. It used to burn a bit more oil than it does now, but tuning it and fixing the timing made it better. Hopefully it's not a head gasket (my worst fear, as well as O rings), because that takes my only ride out of commission for a while if I do it myself, or a big chunk of cash if I take it to a shop. I checked the oil and coolant, both are okay. I can't REALLY see into the radiator (aluminium performance radiator) because the way its designed restricts your vision, but the radiator cap had some coolant on it and it looked alright. Should I drain and refill the coolant just for safety and take a better look at it?

Thanks. Surprisingly, mine hasn't been too much of a pain lately. I changed the spark plugs, adjusted the timing, and that's about it. The problems started piling up today and yesterday though lol, back to work!

I'll get right on that, thanks! I haven't touched the head bolts at all, so it would be somewhat peculiar for that to be my problem all of a sudden. Hopefully that's not it, because chasing down the cause of that might be quite a hassle. The majority of the time, it burns clean. Rich, but no smoke. On cold starts (not very cold in Florida, though), it'll smoke white. It smells odd, but it doesn't smell sweet, so I don't think its burning coolant. It does burn oil very slightly, but not enough for the exhaust to smoke blue. Sometimes it'll smoke a little (barely visible) blue but once it warms up, it goes away.

This is pretty recent. I often pop my hood just to take a gander and see how things are going. In the past week or two, this happened (since the last time I took a look around). I'm assuming its water, since there's rust, but I'd need an expert opinion on this as this is way above my level of expertise. I took the car in this week for a carb tuneup (I'm absolutely useless at tuning carbs and can't figure out how to tune my Holley). The guy mentioned lower vacuum on one of my cylinders. He didn't do a compression check, but he said that the car wasn't really firing on all 6, but wasn't misfiring. If it is this cylinder that's having issues, how could that be related to the rust? Thanks. Edit: Forgot engine specs. Again. This is an L24, E88 head, hot cam.

I'm so lost here. Can anyone chime in? I don't even have front blinkers anymore, which is increasingly weird.

Little messy, but it gets the job done.

Looks good as new under the fusebox. I tried testing the center right fuse (parking and tail lights) with the voltmeter and I hardly got a reading. What would that indicate? I then tried it with the ohm function (read it on other Z websites from people with the same issue) and it fluctuated a lot. Also, about the hazard switch, I took it out as well as I could through the back of the dash without having to remove it, and it seems pretty good. I'll try to see if it disconnects somehow so I can check the connections and all.
