Something I found interesting when I was going through Tomei's site. They use the same valve springs for the VG30DETT as they do for the RB20DET.

I wonder if the stock valve springs are the same part number. If anyone not in the US could go to a dealer and ask about the part numbers of the valve springs for the two motors, that would be great. This might mean we have another part we can use off of companys here in the US and not have to outsource/special order valve springs. If someone already knows the facts on this issue, please share.

Not a bad idea. It would be nice to know the spring force as well.
