So, I've noticed there's a few recommendations for performance parts on the website, but none has been consolidated as of yet. From the obvious, to the not-so;
www.nopi.com - Bunch of crap, nothing specific to the Stanza, but if you look for KA24E or DE, and especially SR20(not a surprise), you'll find some or tonnes. Terrible site layout though
www.frsport.com - Been a reliable site. Has some stuff for the KA24E which is nice. Lots for the DE and SR20's as usual.
http://firesport.com.au - Trading post for performance cars. Hardly any KA24 stuff on here. But then again that's a theme isn't it? Very well known site but needs to be here for completeness
www.summitracing.comwww.atomicspeedware.com - Great stuff. Good prices. Can find anything for a DE or an SR, only a few things for the KA24E but still things none the less.
www.realstreetperformance.com - fairly meh site, cheapest shipping I've found. Some items are ok, some are pretty average pricing. Nothing for the KA24E. DE and SR20 only.
http://www.importperformance.net- reasonable prices, no idea on shipping prices. Limited range of DE stuff, plenty sr20. Almost nothing for KA24E.
www.ebay.com - yeaaaa boi.
As i come across more I'll add to this, but it's midnight and these are the only pages i've got open atm
. Feel free to add some sites and i'll edit this as needed...
