I have an 89 240 coupe and a 90 300zx 2+2. I'm taking every swapable part from the 300z and putting it on the 240. The 300zx is totaled. How hard will it be to swap the 5 lug from the 300z to the 240? And will the vg30 fit in the 240?

http://importnut.net/300zxbrakeswap.htmhe swapped the brakes onto an S14, but you can get the idea for an S13 from it.

the guys that did that write up didn't bolt the rear Z knuckle up to his 240. He swapped the Z brake over to the 240 upright. Doing this allows him to run the 240 suspension. The only problem is that it increases unsprung weight by 7 pounds per wheel. You can bolt the Z upright straight onto the 240 suspension, the only issue is that the Z uses a fork and prong style rear strut mount. The 240 uses a post and loop style. Although I haven't tried, I believe that the Z strut is the same as a 240 strut with the exception being that lower mount point.

On the front, you will have to swap the front spindle over to an S14's spindle. Also, the strut bolts are larger on the S14 spindle, so you'll have to enlarge the holes on the strut bracket to fit. You will also need to get an S14 ball joint to mate to your S13 lower control arm. And you will need an S14 5 lug hub. easy, no?

http://www.sportcompactcarweb....lvia/sport compact car has a pretty in depth article on the 5 lug swap.

as for the VG, it's possible, but I don't know exactly what needs to be done

I looked at the front spindle and the 90 300z and 89 240 spindles look alike execept for the huge upper control arm that the Z has. The Z's shock connects to this arm and then to the spindle. The 240 just has a shock with a bracket that bolts to the spindle. I'll look to see if the bolt pattern for the hug (only) is the same and I'll also look to see if maybe the shock bracket on the 240 will bolt to the Z's spindle if the hubs can't be changed.

Now what about the 240 5 speed transmission? Will it bolt to the 90 N/A engine?

When I did mine, I found that the inner diameter of the Z's rear hub was too large for the S14's axles. I had to cut the Z32 hub apart and use just the "mounting" portion of it to get the Z brakes. Had to keep the S14 hubs in order to fit the axles.

I read the z32's rear axles are longer and 2mm thicker than a 240s

That is correct from what I saw.

The bolt pattern from the hub to the spindle is the same, but you cannot use the 240's axles with the Z hub. If you are doing the rear brake conversion, you will need to cut off the "flange" at the top of the Z hubs and use it to mount the e-brake hardware.

has anyone swapped over Z front hubs or spindles and hubs? I'm thinking of seeing if that huge upper control arm will bolt in with a little fabrication to my 89 240.

The Z has a different design to the front suspension in order to accomodate the wider Vg30DETT motor.

These will not work in the 240. At least they shouldn't -you'd be wasting your time trying to make them fit.

I'm still going to check to see how different the hub bolts to the spindle and maybe I'll have to do some drilling to get the Z hub to bolt to the 240 spindle.
