With Spec-C on K24 you can easily go on 50 degree.
I had my Spec-E on K20 and I could go only max 30 degree, now on K24 Spec-E are on 41 degree. Of course it depends what bore and pistons would be used.

Hi, maybe anybody knows what safe VTC angles with Toda spec C camshafts in the K24 engine ? For K20 it's 45 deg. max.
Higher compression rate, lower VTC angles. If you would run K24 with stock compression rate (11:1) - without changing the pistons to higher compression rate, or thicker headcylinder gasket or skimming headcylinder, I think you won't find any problem to go full 50deg.

lol, stock compression rate is 10.5:1 for K24a2 or K24a3, 11:1 has only new TSX 09+ and Accord CU2

Hi David, is your pistons stock or aftermarket? I assume k20 30vtc is with oem pistons and k24 41vtc is with aftermarket pistons. What is your peak hp and torque numbers, if you give information about your setup I will be happy.

Thanks.
