If it's not really about tuning or wiring. Then it belongs in here.
Can anyone suggest a good source for OEM engine build manuals and reference material? Looking for a good source for tracking down spec's and tolerances for American V8s and maybe a few IL6's.
Most manufacturers now allow you to pay for a time period access to print/save/print to pdf all their workshop manuals for anything they have a digital copy of.
For Toyota (AUS): https://toyotamanuals.com.au/subscription
For Audi: https://erwin.audi.com/erwin/showHome.do
For Nissan: https://www.nissan-techinfo.com/home.aspx
The list goes on. Otherwise if your looking for free manuals, or info, your probably best scouring forums.
Thanks Nathan. I'll give that a go..
