KO3 or KO4 turbo for my A4 (B6) (Arthur Marks)

[thejimrose]

the k04 is a great upgrade on the 1.8t. it's very marginally larger than
the k03 you get a hair more lag but a  bigger whallop. i ran one on my b5
for years.

im a little rusty but pretty sure they [cartooners - giac, revo, etc] do a
few files depending on hardware setup. so you could probably keep the stock
IC, injectors, etc. i would definitely do a high flow cat while you're in
there and probably a larger TIP. good time to upgrade plumbing to
sillycone. exhaust frankly is optional. yea you might give up a few hp but
quiet is nice.

im pretty sure  you can do a tune that would not require injectors. i think
the next stage up requires injectors, exhaust, larger IC.

its really a great upgrade. as for where i like giac or revo - call em up
and find a local dealer. or your local auti tooner, or call 034 - good
guys, good prices and 1 stop shop.

oh whatever you do use a BOSCH fuel pressure regulator. mine ran wonky
forever b/ci had a stupid aftermarket adjustable fpr in there. and use a
stock n75 and 710n.
