Firstly i must apologize if a thread of this nature already exist, but i am having issues finding information on the topic. As the title says I have intentions of mating a 1JZ GTE head with a GE block. I am trying to find a thread but can anyone tell me is there any main differences that would not allows for this to work? Finding a replacement motor for my MA61 seems to be a pain and i am getting a damaged 1JZge for little to no money and would like to know if the block can be used. If not can someone tell me if the 1J VVTI block can work? Thanks to every and anyone who helps me with information.
