If you're close to 60,000 miles, I would change the timing belt while you're at it. I replaced my timing belt and took the opportunity to install Z-Speed cam sprockets as well. Well, once everything was put together I was amazed at how much peppier the car felt around town. Winding it out gave me even more of a surprise. The midrange is the most impressive and the top end is even more frantic.
Torque steer is increased a little but the car pulls so hard, the trade off is worth it.
Still, I can't wait to get a limited slip in here. The car is noticably louder but the roar sounds great and is only present when you get on the throttle. Granted since I did my TB at the same time, that could be the cause of the added noise. All the common bolt ons don't even compare. If I had known the head work would make this much difference, I wouldn't have wasted my time with fancy intakes and headers first.
