Ko3 to ko3s turbo upgrade

[turboboy]

MATE!!!! This is a mk3 ibiza section bit! and your car has a ko3s as standard!think about it!

 

[Big_daddy]

well did that take you that long to figure that out!
Leon section no one knew much so was diverted to this area as these people know abit abot ko3 turbo upgrades

 

[turboboy]

no as soon as i saw your thread i realised the mistake! they sent you here because they prob thought the same as i did (wats this guy on about!)! the big point your missing is LEON CUPRA 20VT,S ARE KO3S TURBO AS STANDARD!!!!!!

(i actually thought he was on about his A3)

the very early leons were fitted with k03 units i think

like early Golfs were

 

[turboboy]

ok wat year in your leon?

 

[Big_daddy]

its a 2000 model on w reg

 

[acidstrato]

iirc all Golf GTis prior to 2001 were fitted with k03 units....but they were also non dbw so as i dont believe any leons are non dbw it aint really much use

engine code would be more use tbh

 

[acidstrato]

AGU - K03 turbo, no VVT, Non DBW, 150bhp, 5speed
ARZ - K03 turbo, no VVT, DBW, 150bhp, 5speed
AUM - K03s turbo, VVT, DBW, 150bhp, 5speed
AUQ - K03s turbo, VVT, DBW, 180bhp, 6speed

nicked from ukmkivs

note: bhp figures dont apply as these are from the Golfs and A3s as well

actuator of ko3

On the ko3, can the actuator be changed on?
think mines is playing up, when the turbo kicks in you could hear some noise after it 2500rpm. checked the pipe from actutor to the n75 it looks ok.

i done this test where i linked the boost gauge to actuator. the boost gauge hardly moves and when it does it moves jus to 0.1 and dropes back to zero.
the other test i done, was press the actuator vacum port with my thumb whiles keep keep actuator throd pulled, (similer DV test). i felt suckion and the spring quickly forces actuator to normal position

The car does not pick up in low rpm at all. any suggestion guys?

 

[acidstrato]

you ca change the actuator but you cant buy them brand new only as a whole unit apparently

dunno about testing it, never had to

stick it on vagcom and run a few logs, much more informative

 

[Forbez]

You'd be better off in the Leon section i think mate.

 

[Big_daddy]

Yeh this headace! may get it checked on a roaling road to see if the actuator actuator playing up!

You'd be better off in the Leon section i think mate.

Compared to leon section not and ibiza section, i get better replies here.

 

[David_smith_909]

yeah, best bet is to get it plugged into vagcom, no one near you with it?? just be guessing otherwise

if all is wrong though and you need a new actuator/turbo, and its a k03, i have a spare one

 

[Big_daddy]

after playing around with actuator today, by checking the vacum line and by moving the actuator rod. the car feels quick!

my car is a w reg, with the app engine code! what turbo does it have then? i dont think its kos! how can i check?

 

[acidstrato]

LOL f#ck knows

k03 turbo has 2 vac hoses on he actuator where k03s has just one if that helps!!

 

[Big_daddy]

where are the vacum hoses? theres one the actuator, wheres the other one? does it be printed on the turbo? can i be abe to see it, or if i get my camera phone down there

 

[acidstrato]

the part numbers could tell you yes, although i dont know em myself, think all K03sports have 50, 51, 52 or 53 in it

the first vac hose should be on the actuator, the 2nd should be below it somewhere

 

[Big_daddy]

2nd vacum line, where does that come from? so i could trace it down

 

[ganda_cupra]

If your on about your leon it will only have one vac hose to the actuator as it will be running a K03s turbo.

The only 1.8t's with 2 vac pipes to the actuator are the ibizas as they use a K03 turbo.

IIRC
