IIRC They were something like 80amp from the factory so there is no real need to upgrade it. So how was the belt wrong? Just the length? E: I don't think firecock is up to rebuilding his alternator himself at this point.

Although an Alternator rebuild isn't out of the question with some measure of guidance, I can and will gently caress it up entirely by myself, and just finding a new alternator is probably a much better option.

Sounds like it had this kind of belt:  when it should have had this kind of belt:  ... or vice-versa because the PO installed a different pulley from the original stock one, and the shop had blindly installed one meant for the original pulleys. e: or not, maybe it was just the length.

You are better of just buying a rebuild from oriellys or similar. Autozone alternators Are poo poo 94% of the time.

Wrong width or length makes sense. Surprisingly many, actually. There's a number of potential swaps, including Maximas, 350z's, and Titans. My original plan was to install a Nissan Titan Alternator.

Well, a Titan seems like it's way too new to be in a junkyard, but there's plenty of 80s and 90s Altimas, Maximas, and Sentras clogging the place up. So if any of those work, that would be my go-to. Plus, you can figure out how it comes apart on the junkyard car, so when you do yours you know where all the bolts go.

Yeah around Chicago the junkyards don't have a lot of z cars anymore. But shitloads of other nissans. Sperg if you wanna go junkyarding let me know. I'm dying to abuse an engine bay.

Worst case scenario, if we don't find any Nissan Titans, 350zs, or other easily slapped in part, Titan alternators are surprisingly cheap on RockAuto, just about 40 bucks more than the 300ZX stock alternator with 60 more Amps. We'd need to change the pulley on it, but that shouldn't be too dire of a task, should it?

Yeah, but a pick-n-pull alternator would be under $40 total. $32 plus tax at my local one. And it's always better to get a junkyard OEM one than a lovely parts store rebuild, IMO. Unless the parts store rebuild is really, really cheap. I put in a Baxter rebuild once because it was cheaper than the voltage regulator my OEM one needed, and I didn't have a ride to the pick n pull.

Meh, I've had mixed luck with Pick and Pulls. Somethings been sitting outside for an indeterminate amount of time isn't necessarily anything fantastic. Besides, there is no guaranteeing it's going to be an OEM part and not a rebuild on the donor vehicle either. Heck, we don't even know the alternator on spergcocks Z31 is original. For all we know, it's a 30 year old car and the PO loved to do modz so who knows what it is. That could be part of the reason why the belt never fit. I like the local auto electric shop idea, old guy on the corner probably missing a few teeth, still smokes while he works but cares about his job. But a quality reman unit like a Bosch might be reasonable too at a jobber so  quote:We'd need to change the pulley on it, but that shouldn't be too dire of a task, should it?

Most bosch products ive dealt with except there injectors are poo poo. And we are near a major bosch factory. Im down to go junkyard hunting for an oem upgrade. Just get your car running and we can hit up some of the local junkyards.

I would find an OEM, buy the one for your car on rockauto, or get yours rebuilt. I have no idea what the Titan alternator requires to fit on your car (and it sounds like you don't either) so it could be much more complicated than your skills allow at this point. Some use the alternator for the belt tensioner and the mounting holes for it may not be the same as for your engine. However, if it's a common upgrade according to Zbros on the model specific forum and well documented on what you need to do, then by all means go for it. Otherwise don't start out trying to make your life harder than it needs to be.

It is apparently a very well-documented thing. I got the idea from a link a few pages back which is a complete guide to how to do the swap, and what (very minor) modifications you need to do for it to be a perfect replacement.

My experience of most cars is that they'll try to keep the (expensive) alternator a common component, and vary the (cheap) brackets and mounts to make it fit different things.

so I checked it out and doesn't look hard to do at all. The hardest part will be getting the alternators out. also may have to modifiy the bracket a little...no biggie. so this sunday maybe we can find a titan that was wrecked..or find any of the other options they list on the z forums. because with the e fans and who knows what other PO fuckery you need more POWAHHHH!!!!

Update: Got a free quote about some rust removal on my car at the local Gerber, because as an Enterprise employee, I get a pretty beefy discount at them. Bad news is, we found some pretty major frame rust on the underside of the car, where the PO had said, "oh yeah minor rust issue". As much as I'm sure everyone is screaming at me, "DUMP IT NOW AAAAAAAAAAAA", I want to see if: A: There is a chassis shop nearby. B: How much it would cost to recover that sort of thing. I understand that most of you can probably just weld on a new frame no problem in your sleep, but I am not one of those people, and I have even less experience in welding or frame repair than I do with cars in general. So, thankfully, I have a relatively large check coming in from the Navy, 'cause dis gon' be a doozy.

Pretty sure these cars are unibody so they don't actually have a frame. Did they show you where the rust was at? If there's a lot of rust in the rockers or the floorpans it's probably best to cut your loses at this point.

It's a long strip underneath the car itself, but it's not on the floorboards. I'll have to catch a picture of it.

I'll take a better look and pictures when I can get under the car to figure it out. From pictures of the undercarriage of the Z31, that MAY be the exhaust stuff that's rusty, and not the actual frame of the vehicle.

Would be pretty funny if it was just the exhaust hangers. Also buy some ramps so it takes like 2 minutes to get under your car to do anything not requiring jack stands. so instead of Sperglord Firecock posted:when I can get under the car to figure it out it's whenever you feel like getting under the car

I actually got those! I really hope it's just the exhaust hangers. That'd be like "WHEW DISASTER AVERTED, FULL SPEED AHEAD". Setting up the ramp and driving up it to inspect more closely now.

Dammit, I wish I didn't have to, but that's a gently caress-ton of rust. As much as it kills me, there's a guy down the street at Steak & Shake that might give me a solid $4000, maybe $4500 for it, and there's an N/A one out in Northwestern Indiana (same color, same year, good shape) that is going for 2500, which I can do right by instead of the hackjob that was done on this.
