So i have searched and searched, and cannot for the life of me find any upgraded parts for the 1JZ heads. I was hoping to find some better springs and retainers, or the titanium sort, but i simply cannot find them any where! Nor can i fin stock replacements.
Im pretty sure the 2JZ springs and everything do not work on the 1jz, so my question is what are my options for replacing, or preferably upgrading the heads on my motor. I already plan to atleast do some basic porting and polishing myself, unless someone can point me to a good place to get it a 3 angle valve job and over sized valves. But then the question again, where do i get these over sized valves!!!?
Any help would be very appreciated. I just can seem to find anything here on SF or on google.
Thanks
