So, I'm doing the z6 swap on my 90 Si. I thought I was getting a Y8, however ended up being Screwed over on Ebay and got a Z6. Luckily the head gasket works and is from what i'm told better, and so did the intake and exhaust gaskets and obviously the water pump because it's on the block. My question is, is the timing belt the same? My honda friend here and in KC said yes, however the part number is a different number. I want to know if I need to waste another $40 on that. As well, the dood that screwed me over sent me the valve cover but none of the bolts, anyone know where I can get these cheap ? This swap is turning into a nightmare. . I'm regretting doing such a thing. My next worry is making the dist fit, I don't like that one bit. Thanks! Dr.
