Just chasing some z31 5 stud jobbies for $200, see how that goes. cheers otherwise might have to get some made.

i thought z31 was 4 stud, any particular year?

Just put sunny top hats in, you'll have to carefully grind down the tower to accept the bigger diameter top hat.

Its reasonably well explained in tech wiki. http://datsun1200.com/modules/mediawi ... .php?title=S13_Strut_Swap
Go there first, might also want to familiarise yourself with the various parts hanging off the macpherson strut.

I am in process of upgrading my suspension and brakes to Nissan Skyline stuff. Will use laurel fillers , avenger springs, GTS-T calipers/rotors. But having trouble finding hubs that will fit over the bluebird stub axles. I've heard and measured that ford falcon ute XA-XF will fit and also old toyota crown will also fit. Any other suggestions? cheers

why do want to do that, is it for brakes or adjustability. The issues you'll hit are the bottom ball joint hence think may need customised control arm.

probably Toyota Hilux LSD, they come in 4.11 are cheap, reliable and very tough. I've heard they are good for 700Hp.

The maximum you can take off a A15 head is 120 thou (3mm), thats with a cam regrind and nothing off the block. But then again a different grind may not allow that. Our reground CAMs are still adding lift however.

yip no problem there, easy swap.

I think the voltage regulator can be adjusted, well at least the external ones can anyways. Also the pulley size won't have that significant effect on it i believe. Thats my 2cents worth.
