Hi guys, i will be putting in some Gsc s1 cams with a HKS pulley to my evo 9. I was wondering if anyone could help me with the timing settings

 

stock settings are just fine. Once you get them in, get it on the dyno and play with the Mivec mapping, and exhaust cam gear settings.
You can see some very nice gains, but every car is different with how they react to timing changes. Thats why we dont have a "set" number.

Good luck, and let us know how it goes.

 

for the evo 9s, i heard some people get a adjustable cam gear for the exhaust cam and retard 2 degrees for more output.

 

leave it stock unless you are tunning it yourself at time of install
