hks step 2 cams

[9240sx]

what do you guys think of the hks in 264 ex 272 step 2 cams.I would be putting them of a s13 sr20det with intake,greddy turbo outlet,downpipe,testpipe,catback,and I have the greddy valve springs,and RAS.This is with the stock t25.sould they make pretty good power?if you used them before let me know how you like them.0r what you didnt like.-thanks,

on the t25 your not going to gain any power, you might even loose some. This is due to the fact that the turbo can't push enough air, so the valves will be open more, and for longer but the same amount of air is going to be comming in. Unless you plan on upgrading to a bigger turbo in the very near future, upgrading the cams, especially to a step 2 264, or 272, is basicaly a waste of money because you will not gain power but basicly loose it.

How about the HKS step 1 in 256 ex 264 would that work better for me,would that setup make me more power?And I will not be doing a new turbo for a while.so I want something that will make good power gains with the t25 and my current setup.-thanks,

The idea is, you are at the limit of the flow capabilities of the stock turbo even with stock cams, therfor, no need to waste money on hot cams.

Oh,i didnt know that.So no point in buying even a mild cam?whats the size of the stock s13 sr20det cams?

[Onizuka]

Honestly, for the cost of a set of HKS cams and cam gears, you could get a new S15 turbo. At this point you would need better fuel delivery, fuel control, intercooler, etc...

A front mount intercooler would provide more power, because cooler air is more dense, and more density means more oxygen, which means more bang. A cheap greddy VSPL kit would give you power now and would be able to accomodate a bigger turbo, cams, etc later when you have to money to upgrade.

On an S15 turbocharger, Tomei 256 camshafts are good for 15whp peak.

So even if I put the HKS step 1 256/256 combo in I will get no power gains at all?I would like to do some kind of cam upgrade,There's got to be a upgrade over stock with the t25 that make power.I feel like I wasted money buying the greddy valve springs and rocker arm stoppers.If im just going to be running the stock cams.

So,No one has used a step1 256 intake and exhaust cam combo on there s13 sr20det?

I think they gave up on replying because they've answered the question about 5 times. With that turbo, the gains will be so insignificant, or detrimental.. you will see no benefit. Spend the 300-400 bucks youd' be spending on the cams and get... at a minimum.. an S14 T28... or the intercooler like someone else stated. The RAS have nothing to do with CAMS they prevent valve float at high RPM so you didn't waste any money putting those in.. and the valve springs will still be there when you have a new turbo in and decide to do cams later.

[nismostate]

geez didn't you ever research before buying RAS? if you want to waste money, get some tuning devices or maybe suspension work.

[9240sx]

I know what RAS do!Im not asking what they do,OK.Im just asking some advice on a cam setup.But since I will losse horsepower by putting in aftermarket cams.I wont be getting them.So dont post if your not giving helpful advice.

[Cyberkreig]

calm down man. Everyone has given helpful advice you just keep asking the same question.

In the end cams are a tweak, the finishing mod to a motor that is already badass.

I have Step 2 264/272 cams....but I have a GT25R turbo.

My car makes big power up top.
