for 250bhp you dont need nos on the 1.8t...


k04 or k03s turbo.. FMIC.. uprated injectors.. 4bar fpr.. 3" MAF sensor.. decat.. Leon cupra R fuel pump.. stage 2 map.. and a few niggly bits..  job done..

my AUM was 221bhp on stage 1 map.. and even had standard cat !!

On the cheap i'd stay with the stock k03s, fmic, silicone tip and a remap for a decent 220-230bhp. K04 means buying more bits changing oil lines and getting s3 gear getting you probs 260-270ish without a cat, If getting s3 gear Id get your k03s hybridised for £600, then get correct running gear then a remap, but sadly its stage 3 so like £600 but thatd give you about 280bhp

People on audi forum used to get the same figures as people who spent on exhausts, but probs felt less free reving, but with k04 and k03s Hybrid youd deffo need a bigger exhaust.

Depends what size you got now though?

Anything more than the k03s I think would need a an lsd. Depends how much moula ya got.

in a mk2 i don't see the point in spending out on a hybrid ko3s or ko4.

you may as well you a std ko3s or kos or go and spend out on a garret GT27RS   and be done with it.  it costs more but it's a better job,  and get the LSD as 200+ bhp without an LSD in frount wheel drive is frustrating to drive

Id be happy with the standard 180 bhp!

But yer thatd be a big lot of money lost if you decide its too much power and rubbish too drive.

Not necessarily. Depends how its mapped.

Ko4 is well worth it. A mate has jus ditched his ko3s for a ko4 setup, yeah, new manifold etc needed, but a big improvement. Well it was until he bent the rods, smashed a hole in the sump and took out a piston anyway... Now guna drop a bam in, or forge any old 1.8t up and be done with it...

Ouch sounds rough. Is he selling the k04 setup ;)

If you are going ko4 why not go hybrid on ya k03s?
Title: Re: mk2 turbo
Post by: bosco on 02 February 2011, 17:23
If I go hybrid do I have to change manifold and Oil lines?
Title: Re: mk2 turbo
Post by: mk2bal on 02 February 2011, 17:32
I thought the ko3s was hybrid already? Nah its guna have wossner rods and be back sorted soon... Its a brand spankin genuine k04, from tps I think..its the 3rd time its bent rods! Too much rpm! He checked a tt out and they redline at 6250 or 6500 or somethin, he's been takin it upto 7k ish, goin to the mk2's redline. Oops.oh yeah its a big differnce wit k04 so do it in the first place and future-proof it. You will want 1 1day

No its the same turbo mate so exact same setup as you have, but with the s3 gear ( not manifold oil lines etc but the rest of the gear youd use for the k04 upgrade, my mind has totally gone blank, am trying now to find out what the s3 gear is!!!)think it may cost more than k04 conversion just because of stage 3 mapping £600 and £600 for the your turbo to be hybrided.

Would ya do it yaself, the fitting, if so shouldnt be more than £1500, for about 270 280.bhp

Post by: bosco on 02 February 2011, 19:45
Cheers man I will be fitting it myself I will find out what the s3 gear is and start getting funds together :)

Ahh itll be cheaper then just the turbo and mapping will do ya in!, I'll look for the list on audi-sport for, says exactly what you need.
Title: Re: mk2 turbo
Post by: emery1990 on 02 February 2011, 20:06
s3 injectors 370cc 80mm maf housing, depends where you get it mapped but dont need a 4 bar regulator, you got a fmic ?  So not alot after ya got the turbo.

My mate paid 330 for his genuine borg warner ko4 through his work..qpeng downpipe etc and a free map, job done I think he adapted the water/oil lines to fit, but not 100percent sure what he did in the end...

Ko4 could work out a bit cheaper, but  youd wipe the smiles off other mk2 k04's in the hybrid!
