You can bolt heads on. LOL. Go for the electric water pump if money is not an issue. Some hp there to be had.
+1 on the EWP. More hp/tq by a few, but the real gain is gas mileage improvement. I am getting 34+ mpg on the Eway in 6th with cruise set at 80 mph. I'll update everyone on my gas mileage after I drive back from Texas (LG Motorsports) next week now that the final phase of my car is complete.
Last year 1200 miles in just under 35 gallons.

Might not be as big of a difference as us A4 guys going 3.23 -> 3.73, but 4.10s might be nice

your 480 whp ar gets 35 mpg that must me nice. i dont see highway that much but i get 210 to a tank before my guage comes on.im calculating 15-17mpg. so i guess it would be a good investment. thanks
