Thinking of buying a 91 300zx N/A

[Exia]

Ok I found a 91, has 165k on it guy says he just got the trans rebuilt and also replaced solenoids in it.. Is there anything I need to look for?

[Oh Em Zee]

Records of last Timing belt \ 120k package completed, Injector replacement, PTU recall performed are the 3 major ones.
Everything else is small maintenance items to get the Z running properly like OEM fuel filters and spark plugs.

Is it NA or TT and how much do they want?

Is it NA or TT and how much do they want?

The title says NA

[300ZXttZMAN]

Also look for rust.

[Ziggy1621]

Just read OhEmZee's sig, lol!

[Exia]

Well I traded my Ford Expedition for it, it had 191k miles on it, Its not the one I wanted, wanted a 5sp. or a TT but its my first RUNNING 300zx, does have some minor rust starting to show on the bottom skirt next to the rear tires, has some sun damage on the top part of the back seat, besides that interior is flawless, all leather, has factory floor mats, trunk tarp, T-top covers, T-Top Bag.. Needs a Head Unit, Minor tune up, no leaks, doesnt smoke, trans was just rebuilt w/ shift kit. Trans does kinda act funny, one minute shifts from 1st to 2nd @ 3k, or will shift @ 4k, But did notice the trans cooler is unplugged, could be the issue?

Does have a full Greddy Exhaust, Bembo brake kit, custom system, I believe it may be lowered, but all in all runs real good.. everything works but rear wiper

But what do you think I get screwed?

[Ziggy1621]

Looks good. Maybe do the maintenance on the transmission and see if that does any good. These cars really like Motul transmission fluid. So look into that when you replace the fluid.

[Oh Em Zee]

What was that? Automatic transmission is slightly dirty? 5-speed swap time !!

Like you need an excuse for a swap

[DCaff300ZX]

Having the solenoid unplugged and an ALC controller ("shift kit") is most likely not good, as the ALC controls the fluid pressure in the trans for shifting purposes and needs full performance from the trans cooling features or premature wear is inevitable.
I would get the full trans rebuild info to see just how far the trans was reworked, since in my case using the ALC for about 3 months completely toasted my just-serviced autotragic...and as Oh Em Zee suggests, sent me on to my 5-speed swap far earlier than anticipated...

Car looks clean.

Check to make sure the TPS is within spec first before speculating anything. This will make your auto shift in a very odd fashion is its not set within spec.

When you said the transmission cooler is unplugged, from where? Radiator? Aftermarket cooler? If from radiator, See if he had it going to an after market cooler. It needs a cooler to perform normally, if there are no lines going into the radiator, get an after market one, the transmission will be much happier instead of it cooling through the radiator.

[Exia]

Here is what I got from the owner

Car sit for 6 months till the trans got rebuilt, but after the rebuild the shop didnt replace the solenoids, so he took it to another shop to get those done, engine light is off, the shifting only does it to 1st to 2nd the rest go fine 3500 rpm no jerk/hard shift..

It has a intercooler underneath front bumper next to the air filter it is unplugged, I havent looked @ the radiator yet, I will take a good look once it stops raining.

Also, I believe it has a small exhaust leak, and does require a tuneup, it has a big miss, my expedition did the same thing, shifted weird, loss of power going up hills, and constantly had to give it more gas to run right/shift right.. So maybe once I replace plugs and coils, could just solve my issue

[Ziggy1621]

Take a pic of this 'intercooler' pls and post here

Also, read this, scroll down to the section "The 6 Things you should do to your newly purchased z or a z that has been running kinda ruff or is .."

If the trans has a true shift kit, that could be why it's shifting "hard".

Since your the trans cooler you see up front is disconnected, someone probably reconnected it to the stock cooler at the bottom of the radiator. When you look, there should be two rubber hoses coming off the bottom of the rad going to 2 metal hardlines on the bottom passenger side of the engine.

The "miss" could just be from having old injectors. The coil packs are less likely to fail than the injectors. You can go ahead and change the plugs, but make sure you put the right ones in.

As for getting "ripped off", I say hell no, I would trade an Expedition for a Z any day. All in all yours looks pretty clean/solid

[Exia]

As soon as I can I'll get a pic of that cooler Ziggy.

As far as plugs going with NGK G-Platinum, I am getting some new coils as well, and might as well order some injectors, so I can just do it all at one time. That way at least I eliminate those 3 things from my "To-do list"

Now if I can find couple cheap, Greddy, & Nismo decals.. Sure as hell not paying 20 bucks for adhesive paper.

[Exia]

To verify, yes, I the trans is hooked to the bottom of the radiator, should I consider hooking the lines up to the small cooler under th bumper, or leave it alone?

[nissanfreak12]

Before you hook it up, take it out and clean it. I mean get a chemical and flush out the cooler, it is possible the old transmission had catastrophic failure causing metal to go through the system. Like the torque converter failed. If this happened, there could be metal chunks in the cooler. If you hook the trans up to the cooler it could send the metal back into the transmission, causing it to fail.

Personally, I would either keep it hooked up to the radiator or just get a new cooler. An aftermarket cooler will prolong the life in your transmission, just cause it will keep it cooler.

I wouldn't worry too much about the coils, they rarely fail, and they are very expensive. Spark plugs I would only stick with NGK PFR6G-11, you cannot buy these at your regular autoparts store, usually hve to go through Z1, conceptz, specialty z, etc..

If your going to get new injectors, get the new style injectors with the adapter kit and new plugs. NOT a bad decision, they will last longer, I got better mileage and smoother idle. Look on twinturbo.net, under classifieds, user Bernie has sets he sells all the time, already in the fuel rail. Not a bad price either.

One last thing, don't put Greddy stickers on the car, please. Don't "rice" up the z, this is a heritage car, a lot of history, not a honda civic or a "teggy", with v-tec yo! This is my opinion though.

[nissanfreak12]

If all your worried about is the transmission shifting hard from 1st to 2nd, this is normal. Especially if you have a shift kit in it like stated earlier. Every 300zx with an auto that I have been in, always shifted harder than like a normal car. Not so hard it makes a loud thud, but just hard enough to perk up the passenger. If you are worried about it, they do make an additive that makes the torque converter slip just a little bit more so the shifting isnt so harsh. Do what you like with the additive, a lot of people don't like adding them, I personally had good results with Redline transmission one, made the transmission shift better.

That car is clean, the stickers ruin it. When I used to live in Phoenix, the only cars that had those type of stickers were beat up, run down dsm, civic, and integras. All of them thought the stickers made the car look better, I honestly think they were holding the car together. They honestly needed a good paint job and some love. It seemed they spent all their money on "go fast" parts, none on actual looks. All of them only had speed cause of nitrous. Take them off the juice, you still had a loud fart box that couldn't get out of its own way. The ones that had some real power behind it kept to the true body lines and no crazy body kit, no stickers on the fenders, or hood, or window, or tires, well you get the point. Stickers on cars just don't look right, in my opinion.

Ok, to get back on topic, OP, if you want to put stickers on, its your car. If that is what you like by all means, have at it. Just be ready for criticism if you post on the net from other members. Some will praise, some will eat you alive. But, this is your car, not theirs. You have a Z, that is all that matters. Enjoy the car, as we all do.

Yes, I agree I was going to put 2 small ones on the side window, but since I am going to redo the car in Z1 gear I will get 2 small stickers for the port windows and leave it at that.. Got to @ least promote the place I am getting the good stuff from

As far as recent updates once I changed the plugs it didn't help the miss any, but further research I found out that the 2nd coil on the driver side ( #4 I believe ) isnt firing. Well I don't know if its the coil or injector, I unplugged the coils one at a time while it was running. And that one didn't change like the others.. So since it is @ 165k I am going to get new coils and injectors just to eliminate those from the " Could Be " list..

As far as future endeavors, I am going to save back some cash and do a Full TT and 5sp swap. I can get that done for 1500.. with me trading my motor and trans in with it..
