HKS GT-SS + What Cam?

[Johnny_9]

What is a good cam to use with GT-SS & Thx?

i used HKS 264/264 step 1 with GTSS.

I liked it although the power was abit higher on the rev range.

I think 260/260 would be ideal?

Would lower duration and higher lift (especially on the EXH) give a better response? 252/10mm?

260/260 10.25...a good compromise between response & power IMHO, its well suited to GT-SS/2530 sized turbos....

Low profile cam like 256 or 260 is used for car aiming low n mid rev torque, High profile cam (272 above) mostly use for drag which aiming a fat torque at high rev.

Lift just lenghtening the valve time to open but will induced large negative acceleration which mostly `jumping or bouncing`phenomenon occur.
