Just want to add another +1 on Reza's work.
He did some maintenance (timing/waterpump/balance shaft/5th evo gear upgrade/Master cylinder back to OEM; don't ever buy the chinese one!).
He found out my balance belt was off by 3 teeth, car is ssssoooo much smoother now. Also replaced the crank shaft pulley which I was pretty sure was on it's way out. Sure enough, it was, badly.
While it was there, his body shop neighbors fixed my rust hole in the wheel well. Very well I might add.
Which now allowed me to put Corbeaus and not feel ashamed at a light when all my pulleys are squealing next to soccer moms
Quieter on the highway, lower RPM and less gas. A little less nervous in 5th when you want to pass someone, but definitely still doable. For long journeys my ears will approve lol
