This may have been suggested before but at least it's all in one place and you dont have to download it. I have used this site for my is300s for years. This was really helpful for the non-vvti 2jz-ge though which if you have not looked lately is in your cars too unless you did an ls swap.

That is a nice online guide for the supra,

if you have access to an FTP program to log into ftp servers we have the GS300 full TSRM and electronics manual.

 

Nice whats the link and creds i use SmartFTP. That guide always comes in handy for motor work on the 2jz-ge. I would like the full manual for the gs300 too !
