How long the install would take ? (I don't do it myself, the shop gonna do it).
Is it reliable ? (i have 85000 miles on my car).

Do I need a new cluch ?

Thanks.

 

You don't need a new clutch, but you will need a new chip.

The K04 is as reliable as the K03

 

its the most reliable turbo upgrade out there rite now

 

You will prolly need a clutch, i had 10k on a stockie and mine was useless.

 

well u wouldnt have to have a clutch but it may be hard to launch it will and old stockie on there. Its not a require ment but if ur going to launch it u will def need it. The K04 is very reliabel it is actually used on teh s4 biturbo to replace the bad turbps b/c they are more reliable than the K03 plus u can get some crazy power. U wont be dissapointed.

 

... that's not necessarily true. I mean, some people I've heard of expected a lot more from their K04's... You will get a good amount more power, but it's not going to be any drag car. It's an upgrade I'd do if my turbo went bad... I'd never replace it with a K03. Otherwise, I'd either live with a K03, or go big turbo.

EDIT: however, you will not be dissapointed in it's reliability.
EDIT AGAIN: Oh, just a thought... Go drive a 225 hp TT. They have a K04. The A4 would make more power though, because you'd have much more agressive tuning. But, it'll give you an idea.

 

Good post^^^ ko4s dont make power, they make torque, lots of it. Ive seen graphs of over 350ftpd, my 1st and 2nd gear are pretty fast. Although, chris is right, not a drag turbo, best ive seen is 13.6.

 

13.6 is still a big increase over stock but i see what ur saying if ur going to spend a grnad why not spend 2 and get a GTRS turbo. But those arents so reliable. The pes T28 is the only turbo upgrad ethat makes a good amount of power reliably right? But then with that its nothing amazing.

 

Naah, apr stage 3 is pretty reliable and faster then t28. Obvisouly theres some things you are going to have to make it run right, but its pretty reliable.

 

any audi tuner will be able to swap in a new ko4 in 3.5 - 4 hours. I've had my ko4 for a couple months now and i'm quite pleased with the results. Pulls real hard in 1st and 2nd, but yeah the clutch isn't really much of a match for the new added power. There are other things you'll need/want to upgrade like DV, fpr, hi-flo cat and chip tuning.
