more power
I am looking for some more power with out changing the turbo and intercooler. So far I have added the turboxs utec and within the next few weeks i will add the helix up/down pipe combo and the hks hi-power exhaust. Are pulleys a good option. I was thinking the perrin crank pulley. Any help would be great.

Flywheel instead of pulleys!
Get a lighter (but not too light) flywheel. By getting a 14 lb flywheel you'll make a world of difference in throttle responce and it'll make your car a lot faster.

IMHO, pulley's and flywheels are small-gain mods for the pain in the **** they are to install. I've read countless threads about misfire CEL's triggered with lightened flywheels and underdrive pulleys.
Intercooler hoses and a GOOD tune on the UTEC will make your car scream.

Flywheel would be better then the pulley. Don't do both, though. You will have nothing but problems. A 12-14lb. flywheel would be good. You will notice your revs climb faster. It takes getting used to driving, though because your revs also want to drop faster.

6-8 lb. flywheel will throw CELs all over the place, and it will make it very difficult to launch. I don't think anyone even makes one that light. The fidanza one (the lightest I know of) weight 10lbs.

DO NOT GET 8 lb FLYWHEELS!
The stock flywheel is a cast piece that weighs about 24lb, A good aftermarket flywheel should be machined out of chromoly steel and weigh around 14lbs. By getting a flywheel that is lighter than that you are going to cause many problems. An 8 lbs flywheel will do the following for you:
1) Have a negative effect on driveability by making rev-matching more difficult, making starts more difficult, and making smooth shifting a thing of the past. If you revs rise quickly they'll drop quickly too... Forget about your wife ever driving it again...
2) It will throw CELS.
3) There will be more stress ont the various drivetrain and engine components. The massive stock flywheel absorbs certain frequencies and acts as somewhat of a damper. A flywheel thats too light will loose that ability and may allow some resonant vibrations through the rpm range.
4) If a flywheel is too light it may have compromised structural integrity and may crack or fail catastrofically.
5) A flywhee thats too light will be more prown to overheating, clutch slip and warp.
Bottom line, stay away from those "ultra light" flywheels unless you want an "ultra huge" headache.
Get a "lighter" one (14lbs) from a reputable manufacturer and be happy!
Of course, if you are a masachist, that changes things...

My wrx is a secound car, so i don't mine making to many changes that will make it a non-daily driver. Is the 14lbs fly wheel safe to use, and if so does any one have one that has not had any problems. My other ? is will it effect the top end performance since it is lighter. It seems to me it might effect it in a negative way. I have no idea, just thrown it out there to be discused.

I installed a lightweight flywheel in my last integra. The stock clutch lasted 60k miles, my upgraded clutch started slipping after 20k.
The car will definately feel better, but the higher rpms required to move the car will kill your clutch. My 2800 pound integra had a 18 pound stock clutch. I went to 8 pounds.
IMO, I would not do it. In a turbo car just add a pound of boost or so.
