2664 compressors I believe are more plentiful in the US as you guys mostly had K26 2664 4.10 turbos on your cars. In the UK many trashed turbos were replaced with K26 2660 6.10 or 4.10. I had to sourc ...

Anyone got some decent modified 931 / CGT spark tables for reference. Some knowledge of the cars mods/spec would be really helpful. Just looking for some sense checks.

Thank you in advance
