i want to change my 4 lug hubs to the 5 lug hubs. The 87 parts car that i am raping in the junkyard has the 5 lug hubs. I am wondering if there is any fitment issues taking the 5 lug hubs from the 87 and putting them on my 86?
As well as if they changed the bearing sizes and all the other pieces that go with it between the 86 and 87 models?

 

same thing I TOLD YOU the last time you got your head up your butt or you are just posting to hear yourself talk. If you are into raping cars you are one sick individual.

 

All right dude. I don't know what the F your problem is. I have an 86 with a F'in 4 LUG set on it. Do you want me to send you F'in photos. That is the reason i am asking for advice.

 

then you don't have a turbo car OR someone swapped out wheels and sold it to you

 

All '86 USDM Z31 cars, NA or turbo, came with 5 lug hubs. If you have a true '86 model, then rogerz is correct in that someone had previously swapped hubs on your car. The '87 hubs should transfer with no problems. You might consider recording your VIN and checking one of the on-line VIN decoders to see if you truly have a '86 car.

 

ken, from my understanding, the car was originally purchased by a person in NY state from a dealer in Canada. It is a base model 1986 300zx NA, (Vin confirmed through my insurance agency) it has no AC, manual seats, manual windows, no extra electronics other than the base systems,( headlight switch, defogger etc)
So yes it has 4 lugs on it. I found a 1987 non turbo 300zx in the junk yard a few weeks ago. Actually a great find considering it was the only one and still had everything in it when i got to it. I like the stock rims on the 87 (has the corvette look with the venting in it) so i pulled them off the junk car and am in the process of refinishing them. The issue was to go from the stock 4 lug system to the 5 lug. So ken thank you for letting me know that they are swappable, or is there someone who sells the parts and just go new? Pulling gate hubs off might be a pain in the A, considering rust and old bolts.

 

Then you must have what is called the "SF" trim that was sold in Canada, but not the US. I've never seen one, but yes, the SF was supposedly devoid of most features found in US cars. I don't think this matters regarding the hub upgrade. You may have to salvage the front spindles and back 1/2 axles from the '87 if the hubs do not work with the Canadian setup.

 

that is what i was thinking i will have to do. Hopefully it will be an easy (not so easy) pull off of everything from the front and rears of the 87 in the yard and then put them on my car of which i will need to change the rotors and all. I am doing the shocks and springs anyway since they are needing to be replaced. I am in the process of gutting the car and sound proofing it. I do custom sound systems and lighting in cars so this is my new project. last two was an 2012 Hyundai Tuscani and then an 83 delorean. Always fun but always a challenge and new problems to solve. Thanks for the kind response ken.

 

The fronts are easy. But from what I've read the companion flang on late mode rears are different. They compensate for the extra 10mm. Your better of swapping the whole subframe. Its not that bad of a job, and you can do the bushings at the same time.

 

I dont kow what you mean by changing the sub frame. But the fronts should pull off and pop on no major changes needed? Do you know te size of that center bolt holding the spindle on?

 

Did a sub frame swap on my 86. Mainly because I had poly bushings, and replaced the whell bearings on my 87. Plus 87+ control arms are also 10mm wider and have vented rear rotors.

 

Sh** that is the whole piece together. Is it easy enough to get off, since i am going to be doing it in a junk yard with no power tools or compressor just my body strength, and what tools would i need to do that kind of job?

 

oh and i asked this to another user who said to do the same thing, but will the 87 sub frame mount right up to the 86?

 

Metric sockets and wrenches, breaker bar and PB blaster is all you should need. Think it's like 12 nuts and bolts to remove.

 

the thing that worries me is the rear end, if the gearing from the junked 87 is still in good shape. it is going to be something i have to put on the back burner now since it is going to be so much work and no space to do it. Had it been an easy swap, it would have been perfect. First thing first though is to finish the stereo and interior rebuild since it is all apart now.
Thank you all for the great info.
