I have problem with my sammy 1.3 8V 1987. The head has bad cam and it has noise. So I have to replace hole head. Fortunately I have 1.6 8V vitara engine with bad block, so I decide to put its head on sammy 1.3.
As I have measured nearly everything is the same exept fual pump, which sammy has mechanical, and vitara has electric, so I have to make electric fual pump for the sammy now. and the intake valve diameter is a little bit larger, then on sammy 1.3 head, but I think it will go.
The problem for vitara 1.6 8V head is that, one valve is burned, so I have to replace it, but I am planning to replace all vitara intake valves with sammy 1.3 head intake valves, so after that valves will be the same diameter and sammy will have all valve in good shape.
In addition I have to check cams, if both heads has the same type of cam, so they are opening and closing cams in same time.
If this will not help and I will not be able to put 1.6 8V head on 1.3 sammy engine I will have to buy new one, which is not quit easy to do because I leave outside US and shipping is the problem and costly.
Please help me with your advises.
