I have a s14 blacktop and a gt2871r.64 considering getting the HKS step 1's my tuner says you need to get a cam gear for the exhaust side. Just wondering if most of you guys are using cam gears and if you reccomend it?.

I guess he is thinking about spooling the turbo earlier this doesn't bother me it isn't laggy now. What I want from the cams is a flatter torque line not dropping off so soon and to make more power I am at about 320whp on 1.2 bar at the moment, what kind of gains would I be likely to see with these cams at that boost level???

TIA.

Most don't use cam gears with such moderate cams.

cam gears are a good thing to have if you can spare the money for them...

Here in australia I have seen a S15 silvia pick up 10rwkw from an adjustable cam gear it was mostly in the midrange where it picked up the power and i think something like 3kw in the top end - power delivery was better everywhere and for the money its a good investment.

From memory i think they retarded the exhaust cam gear by 2 degrees which = one mark on the cam gear...

How about cam gears on step 2's?

I have the same turbo, and i plan on using step1 264's. I dont think cam gears will be as useful unless you were using step2's. But some people have used them anyway. Its alot to pay for minimal improvement.

I think they are useful if you want to make adjustments in your power curve, if you are setting up the car and need more power in the mid rpm's or something specific I would get them, but if you don't know how to tune them then just get the cams and enjoy. You'll be fine without them and make good power, they are more for fine tuning your curve or squeezing ever last bit of power from your engine. With higher lifts they become more important if you need to adjust the cam timing to avaid valve to piston clearance. But even with step 2's they aren't required, just a useful tool for those that know how to tune them.

I run HKS cam gears.. But I also run HKS Step 3 272's.. They were nearly required because of my milled head, and higher compression pistons..

Thanks for rhe input.

Would the cams HKS step 1's put upto around 350-360whp with the gt2871r .64 on 1.2bar? Anyone have similar setup?

F the step 1's. If you are going to do it, do it right. Get 264/272 step 2's and comp valvesprings.

The hks step 1's should be fine with your setup. They seem to be one of the best choices for your pwoer goals and turbo selection. There really is no reason to go any bigger unless you plan on changing turbo's and pushing things harder later on. Good luck man.

Thanks, you think they alone plus retuning will give me the extra 40whp I am after plus hold power on to towards redline?
