Ok I have a 2000 A4 1.8t FWD with 142,000 miles and am about to replace the OE clutch due to it being worn bad and the OE turbo because I want something with more power. I don't want anything ridiculously fast just a daily driver with some get up when I need it(and a minimal budget)

There are some k04 turbos(or knockoffs) on Ebay with mixed reviews on the board so I may just send mine off to a reputable rebuilder if anyone can recomend one.

The ECU I don't really care everyone seems to be chipping for around the same price

Read about someone around the boards that can polish the exhaust manifold

What other things should I be looking into?

Can I use a new OE clutch kit with a lighter flywheel with this setup?

Any reccomendations would be much appreciated along with links and or prices

 

Send your K03 into G-popshop.com and have them rebuild it into a k04 spec turbo. Cost: $425 +$25s/h
get your ECU chipped from a GIAC dealer or AWEtuning.com cost will be $600
Full exhaust - go custom - maybe 300-400
other options
FMIC - Ebay DIY would be fine - unless you really want to spend a $1k
I would suggest getting a beefier clutch just to have fun with.
Test pipe and down pipe
the list goes on and on

 

I dont think anyone from here has any experience with a gpopshop k03/k04 spec turbo... I would personally wait for a first hand review on it before going that route. Im just wondering how it reacts with k04 specific chips compared to a straight from the factory k04... It shouldnt be different, but it would be nice to get a review from someones personal experience.

 

After k04,
get a catback exhaust, I would go with a borla or miltek, as its stainless all the way back and mandrel bent. (wont ever rust)
test pipe if you dont have emissions
fmic
chip and dv of course, if you dont have dv already
dont go oem, get a stage 2-3 clutch so you dont burn up the oem
That should do it power wise, I would want handling and braking upgrades before/at same time as well. (coilovers, drilled rotors, better pads)

 

gpopshop is a great place...

 

I thought the Ko4 had the same eghuast housing bigger CHRA and larger port on the inlet..

 

The more I keep reading the more I have questions. I have the ATW engine is there any advantage or disadvantage to it?

Can I run a test pipe on it without a cel coming on?

An which chip should I run with it to ignore the cel (if possible)
