But KO4 will not give earlier spool than a KO3 either

LOL.

Go on credible expert god tuner then, show me 3 examples where a KO4( the one with the same turbine) dropin, with the same exhaust housing and tune  and Downpipe spools faster than a KO3 thats actually not a test variety difference. I'll revoke my comment just for you  Kiss

I don't want to be rude, but you are idiot, who is going to rune this forum if you continue doing that what you are doing. Stop stick your nose where it doesen't belong.
No you are not God, but you get wrong in every second post, so you are not the man, not a tuner, not God, you are simply spamer and troll
BDW.  For your information K04 have bigger turbine

I don't need to show you jack shit idiot troll.
Anyone who has ever tuned any of these before knows this. The difference is close to 500 rpm between a S3 and A3 1.8T.
Also a K03S and K04 do NOT have the same turbine wheel, no clue where the F... you got that information. Look at the spec sheet for a K04-023 and a K03S.

AFAIK , there is one KO4 suffix that has same turbine and shaft as a ko3 only compressor wheel and housing different, there like 10 fuckin ko4's. That is what I am talking about. Also what I said, IF the turbine and the shaft is the same( and turbine housing), the tune is the same AND downpipe/exhaust , you very well know that them theortical turbos will spool at the same time even the one with bigger compressor a bit slower...


Funnily enough, my posts help/helped people , and sometimes they are fused my opinions so if you dont like that shit dont read it. Atleast you have some "credibility" that you can argue with people , but you BlackT fuck off seriously. Havent been for 2 months and start acting you are "master" prj. "rune" this forum lmao.

fuck this.

The car in topic is 1.8T.
The turbo for the 1.8T is the K04-023.

1. The turbine and compressor wheel are different
2. There is significant difference in spool, response and top end.

If you already have problem with torque at low RPM, then putting a bigger turbo on it will only make it worse.

End of story.

mk4 1.8T AUM


« Reply #22 on: July 23, 2019, 06:48:35 AM »

There is no k04 with same size k03 turbine
Even 001 has bigger one and that's the reason they're named it differently  Smiley
Back to the topic,  I've buy once a k03 k04 Chinese hybrid from ebay
Basically they're using k04chra with k03 housings and named it k04-001 (but yes,  it's a k04-022 42mm comp wheel)
With 0.6 bar actuator spring this turbo gave
1.5 bar @3000 and 1.3@redline  with 220gs so it's a pretty close to a stock k04022
Awesome bolton mod imo if sharan engine has the same turbo as transverse
Idk about mileage of that one (I've sold it after this lil buster bent one rod)

My bad then.
For some reason I read one of the ko4 had the same turbine as ko3. Probably was some chinese hybrid or bullshit.


"If you already have problem with torque at low RPM, then putting a bigger turbo on it will only make it worse."

Exactly, that is what I said in the first post. and IMO the turbo on 1.8T is already small enough , if someone wants torque at 2k or lower then he/she needs to buy a diesel, We have more RPMs to play with.

And yes the sharan engine mk1 is the same as all other 1.8T. except for the intake manifold if i remember right.

If someone interested, its sharan MK2 (2005-2010years model). And yes, it has traverse engine like golf, a3... Sharan AWC engine is like others 1,8t engines with AW(-) letters, small ported head. Inlet manifold looks like audi tt BAM. Sharan has one advatage - front intercooler(it's small, but more effective than golf, a3, a6...). One interesting thing: sharan weights 2tons, better acceleration from zero (on asphalt) is with front wheel drive(haldex disconected, tires burns, engine runs at high rpm). With haldex engine doesnt have enough torque to slip 4 wheels, rpm drops and car acceleration getting worse. For this reason is very important for me to keep as much as possible boost at low rpm. I think k04 is probably only one solution to get more presure at high rpm. This is my daily car, so always driving in the city above 4k rpm with T4(or same big turbo) would not be the right option. And about diesels, this is not for me, 1,8t runs pretty good.
P.S. sorry for my english

A t3/t4 small frame will be fully spooled at 4k btw.

What you're failing to see, is that all these "for some reason", things you post here, you present as absolute facts and truths, that other n00bz like you will read and take for absolute gospel. Which is the exact reason that if you don't have absolutely verified and 1000% true facts to post, then refrain from it and keep your "for some reason facts" to yourself, instead of passing for an absolute fool on a public forum.

How about K04 hybrid? Buying used k04 isn't good idea, new costs about 1000€. Another interesteng point about sharan(it has transverse engine) - k04 from tt, s3, leon cupra, skoda vrs doesnt fit, but fits from longitudinal engines(A4, A6, Passat). I can get remanufactured k04 or add 100€ and get remanufactured k04 hybrid - is it worth to try?
