Hi, maybe anybody knows what safe VTC angles with Toda spec C camshafts in the K24 engine ? For K20 it's 45 deg. max.

Theres 3 or 4 different kinds of k24 piston , which block do you have i.e. K24a2?

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.

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.

K24a2 or K24a3

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

lol my mistake I was thinking about K20 writing this post, so with 10.5 and C cams you definatelly need to raise up C/R.

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.
