K03 vs K04

[AudI_MaN]

Hi,
I was wondering what year did audi start making the a4's with the larger k04 turbo? Is a swap from a k03 to a k04 worthwile. i heard that the car will run fine even if you swap the turbos and dont get a chip. Is this true??????????

Also, this guy on ebay is selling a whole turbo kit T3/T4 for the 1.8T audi engine. Would the rest of the stock engine handle a swap like this(pistons etc)???

I have a 97 1.8T Q.

ko4 was never in any a4's.. the 01's had the k03 'sport' which is close.. ko4 can runo n stock programming...just not ideal..

as far as the t3/t4.. then engine can handle it... but.. no one makes programming for that setup... as far as i know..and its worthless w/o programming..

if you want a big turbo.. go gt28 or t28..

i thoguht the ko4 was in the 225 hp 1.8t engine for tt's so wouldent it fit?

does the k03 sport only come on the newer shape a4's or does it also come on the older style a4's. I was wanting to purchase a 2000 model older style a4 but am not sure what turbo it has. what boost does the ko3 sport run on stock, and and how much more will it give me with a chip?
regards

the k04 does fit.. i dont think the tt k04's will fit b/c they're for a transversely mtd. engine and tthe in.et/outlet is on the wrong side.. but that doesnt really matter..k04's are readily available...they just dont come stock on a4's..that's all.

i believe only the 01'sd had the k03 sport.. putting out 180hp.. probably like 210 with a chip..

i thnk the engine is transversal also on the gti worul a k04 bolt on that to? or is somthing else diffrent to on it?

No, the tt has a different shape turbo inlet, it wouldn't fit, im looking to purchase a k04 but i was told that it would blow the head gasket and the pistons wouldnt handle it. i was also told by a guy at oeteenger? tuning that with the k04 a chip and a fuel pressure regulator is all i need for the swap, and that after the mod, the car will be running around 245hp, with 19-20psi constant, and under high boost, 26psi. Is this an amount that is able to be handeled by a stock 1.8T Q? The only other mods i have are a Go Fast Bits BOV and a 2.5 inch exhause from the turbo.

haha.. a k04 is not gonna make you blow your head gasket.. the bottom end of the 1.8t is practically bullet proof and a k04 is nothing.... there are no problems running that kind of horsepower.. there are 400hp 1.8t's on stock bottom ends..

you do need a few more things than that.. take a look at www.awetuning.com ..they're having a winter sale and complete k04 kits are cheap.

what king of hp would i get if i just bought the k04 and no chip?

[marked001]

eh.. not much really.. i mean it works.. but its kind of a waste..

it'd be more beneficial and cheaper to just chip your k03

after the turbo and chip upgrade, with a 1/4mile time of around 14.5 seconds, what would be the next best thing to do to get the times in the 13sec region? I forgot to mention that i have a front mount intercooler.

[marked001]

hmmm not much really with the k04... if you want 13s.. i say skip the k04 and get a t28 kit or gt28rs kit... t28 can get you in the low 13s...lemme find a quarter mile chart..

It looks as though the chip made the difference.

00 and up are drive by wire and can use the x chip.. non dbw cannot...
