I have a 93 300zx conv Twin Turbo and I did a compression test with the highest cylinder being 120. Most of them are 90-95 . So I wanted to get the engine rebuilt or buy one rebuilt but it looks like concept z has a very expensive core and Jegs looks like a short block. Any help would be greatly appreciate!
