Default Delta cam: help me decide

Finally decided to pull the trigger on cams, after toying with the idea for almost 3 years...
Car is a 2005 RS with TWE 4-1 header to custom exhaust, LW pulley, stock intake with the STI "air trumpet" added.

The car is a daily driver and the engine rarely gets revved past 5000rpm, so this pretty much rules out the 2000 grind. Plus I read from Williaty's and others experience that the 2005 RS in particular has trouble with this grind...

Now is the 1000 grind my only other option for more grunt, or is there another grind that gives more torque, say from idle to 4000 RPM?
Is it really worth the trouble, i.e noticeable since I already got some extra torque/power from the TWE header?

Engine needs be pulled out soon: timing belt, water pump, new clutch and clutch snout fix...

Thanks!

My brother has an 05 rs and went with the delta 2000's and loves it so far. It doesn't start making power until 3500 rpms but keeps pulling all the way up to 6k and probably 7k if he upgrades the valve springs and gets a tune.

Any way, if you want more torque from idle to 4k or so I am going to recommend the delta 1000's. Were you thinking of getting just a stock clutch and then what about the flywheel? The other thing that I am going to recommend is a 06-07 stock wrx clutch and either a F1 or ACT light weight flywheel to go with the clutch. For reference, the 06 + wrx clutch is a push style clutch just like all the NA manuals except for the 91-94 legacy turbo.

One more thing, if you do go with the lightweight flywheel, you will need to put your stock crank pulley back one if that is the one you changed out for the lighter one. The lightweight flywheel will have much more of a benefit than a lightweight crank or the other two accessory pulleys.

What is your budget for this?

The OP? He doesn't have the cams yet. My brothers 05 rs sounds nasty with how it idles though...

But, you definitely have to drive a car differently with the delta 2000's though.

I have had the Delta 2000s for three years now, going on 50k miles, and I absolutely love them. They add a lot more character to the car, especially from 3500 to 6500 rpm.

However, with the 2000s you will need to get your idle raised as your car will most likely stall when rpms drop past 500. With the 2005 RS you can find someone to reflash your car, so it is a quick and easy fix.
