Did you get a cam card when you bought them?

And 272 degree cams are best suited to turbos of the 2860-5 or T04Z size and will give you only mid to higher rpm efficiency, standard cams are most efficient at lower rpm being only 238 and 240 degree.

No idea what the specs r so im useless

But if all u want is better spool/low/mid etc

Wind that inlet cam gear over 10degrees advance, even 20 if u want, check for valve to piston clearance tho

Ive seen response improvement of 500rpm on a -10 equipped rb26, from cam timing alone

Obviously need a tweak on the exhaust gear too, but cams that size with 20degrees advance on the inlet i doubt will die too much up top.

Dont expect to go too far with the exhaust gear tho, maybe 6 degrees or so max.

Good luck with it.
