1.8t in 4kq REVISED

[Jouko Haapanen]

According to Audi self-study guide #207, the 225hp TT gets the following
over and above the 180hp version:
-coolant after run pump
-9.0:1 compression (9.5:1 in 180 version)
-different exhaust manifold
-twin ICs
-different injectors
-piston oil squirters
-modified turbo ("K03 Sport)
This was current info back in June of 1998, it may all be different
now....but there is still no K04 in a 225hp TT.

180hp: K03 turbo, single intercooler
225hp: K04 turbo, twin intercoolers, cam/intake tweaks and
