Max Lift For Hks Step 3l Springs

[GTR--J]

I have a good price on a set of HKS step 3L springs for HKS step 3 cams. The cams are discontinued so I was wondering what is the maximum and minimum lift you can run with these springs.

The cam size I was interested in are a 280 duration. The cams will be for a BWs300sx 83-75 turbo. The two companies I was leaning towards is HKS or Jun.

HKS STEP 2 280 degrees duration, 10.2 mm lift.

Jun 280 degrees duration, 10.8 mm lift.

Jun 280 degrees duration, 11.35 mm lift. retainers needed for these cams

11.6mm from memory with 3L springs. Just remmeber the valves will hit the pistons with this much lift, relieving is needed.

So the 10.2 and 10.8 should be fine with the springs?
