Det s13 block with et s12 head cambelt,head gasket and head bolt info

[30psi]

I've got the bottom sprocket to use an ET belt still spare.

The head also needs drilling out slightly to take the thicker DET head bolts. Otherwise they're a bit tight and bind.

You also need to put a bolt in the block where the idler pulley attaches to the DET. Remove the stud and replace with a bolt. If you don't oil will piss out as it goes in to the oil drain gallery.
