I do not know much about Supra engines and the repair of them yet. So I am trying to do some research to find engine repair/upgrade guides. Maybe a link to each part or manual for dissambelying the motor and also the interior electrical work. Please provide any useful links, posts, etc if you can. Thank you in advance.

curt (eparts@elmhursttoyota.com) can get you a good price on a repair manual. you will also want to check out mkiv.com's tech section and specification section.
