machining s14 hubs - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have done some searching and still haven't found ANY information on machining s14 front hubs to fit the s13 spindle. Can anyone give me some info on this. Much thanks in advance!

well if you really had searched, you would have found that you cannot use S14 Hubs on S13 spindles.

You have to use the whole S14 upright.

and no you cannot swap bearings since OEM S14 bearings are unreplaceable.

There is also two other things you need to do to use S14 uprights on S13's

Searching will give you the answer seeing that ppl have been doing this since 1995.

S13 spindles are 30mm, S14 spindles are 32mm, so unless you find a way to reverse machine more metal onto the bearing then you can't. If you press out a front S14 bearing it will destroy the hub.

I know this isn't about machining the bearing, but you can also use j30 hubs. You'll either need to use a spacer since the height of the wheel bearings is smaller then that of the oem bearing OR you can replace the wheel bearing with some oem s13 ones.

ok guys, i was just referring to this http://zilvia.net/f/sale-items/31018...-lug-swap.html He was unclear on what hubs he used but I assumed he was talking about s14 hubs since you cant use z32 hubs for the front.

they are OEM hubs...not bearings. Who knows where those bearings came from.

thanks guys, wasn't trying to be noobish about the situation. I've been in the game for a while. I knew you had to use the s14 upright. I have them on my s13. However, I saw that in that for sale thread and got curious and couldn't find anything on it.

Although this does raise the question of "where did they get the hubs?" You can't buy an s14 5-lug front hub without a bearing pressed into it, and pressing the bearing out destroys the hub.

The only thing I can think of is they bought just the J30 hub, machined it so the retaining clip and hub nut would fit correctly on the s13 spindle, then pressed in an s13 bearing. How else would you do it using "OEM hubs"?
