hello.
you probably got this questions alot, but i did`nt find a easy answer to these questions:

i`ve bought a k04 001 turbo to fit my std. manifold (orginal k03s.)
does this turbo fit direct on the manifold and all pipings (oil and water).?
i will replace the oil lines.

i`m thinking of upgrade the fuel pump. the old on is starting to **** up the pressure.
so the question is: do a walbro fit in the tank without to much modification, or is it other better solutions??



im norvegian so im not best in english.

A k04-001 is just a older style k03s so your not realy going to get any gains. It is a straight swop too.

 

[Keith@APR]

A ko4-001 is an upgraded turbo from a ko3s that is overall slightly larger. We typically find the opportunity for about 30hp and 40lb ft of torque over a ko3s at remapped levels of modification.

The ko4-001 was developed by Borg Warner to be a direct ko3 performance replacement turbo and was sold in their Airwerks line of performance turbochargers for transverse 150-180hp 1.8T engines.

Your best opportunity is for a proper ko4 remap which typically includes a four bar fuel pressure regulator to be able to supply the additional fuel that the ko4 requires.

Most remaps will take you from 18 psi with a remapped ko3s to 20-22 psi on the ko4. The ko4 will hold boost pressure longer in the power band and taper to only 14 psi by redline where typically the ko3s will fall to 10-12 psi at redline.

Here is some more info on what parts are typically included in a ko4-001 turbo upgrade kit:

Now that you already have the turbo, you'll need that 4 bar fpr and a proper ko4 remap. You can get both of those here:

I was led to believe that the k04-001 was just a older style k03s and was replaced by the k03s

There are 3 oem turbocharges used on the transversal 1.8T 20v VAG gasoline engine:

Early 150 hp 1.8T's = ko3
Late 150 hp and all 180 hp 1.8T's = ko3s
All 225hp 1.8T's = ko4-020

The ko4-001 was only sold as an aftermarket upgrade to the transverse 1.8T.

One of the wheels is slightly smaller than a ko3s but the overall compressor map shows that the ko4-001 should and does deliver more power at all rpm points above 2000.

Yea,I knew about the k03, k03s and k04-020/023.

Good to know about the k04-001 though

Every day is a school day

Every day is a school day

My problem is that I think I am beginning to forget more than I am learning.

 

[Damoegan]

My problem is that I think I am beginning to forget more than I am learning.

So the k04-001 can take circa 20-30bhp more than the k03s, Keith?

 

[Keith@APR]

With a ko4-001, our remap and a 2.5" full exhaust we make 245hp/275lb-ft on 98 RON on average.

With a ko3s, our remap and a 2.5" full exhaust we make 210hp/255lb-ft on 98 RON on average.

Of course both turbo's will produce higher numbers with additional bolt-ons.

I made 225bhp and 255lb/ft at a recent RR day with the standard exhaust on with 99 RON.

I now have a full 2.5" Miltek exhaust now and are going back on the same RR a wook on Sat so will see what its pushing now.

All k03s stage 2 mapped cars I have seen have made 220-230bhp+

How do you guys arrive at bhp? Is it a calculation by the dyno or by adding a percentage of drivetrain loss to a whp number?

Because every kind of dyno calculates bhp differently, we always talk in whp to level the playing field somewhat.

Our bhp numbers are always whp that has had a modest percentage added to them to arrive at a bhp all of our clients will be able to recreate.

If you are talking about a dyno calculated bhp its hard to compare any of my bhp to your's as they were calculated differently.

 

[Damoegan]

Ah, that makes sense now. Your talking WHP and I'm talking fly HP

 

[Keith@APR]

Sorta. I am talking about our calculated bhp's vs. your calculated bhp's. The real point I am trying to make is that calculated bhp's are impossible to compare to each other especially when we are talking about only 10-20hp.

Yes, I understand and know all all of that mate.

But you say you see gains of 20-30hp on a k04-001 over a k03s (regardles if its WHP or Fly HP)? That was the real question.

As an average across all dyno's in all atmospheric conditions and all fuel quality variances, I can accurately report you will see 20-30bhp over ko3s outputs.

Specifically for your choice of dyno, etc. you may see up to 30whp, it just depends.

I like to give low bhp recommendations to guarantee everyone is satisfied with our recommendations but your results will vary.

The delta is what's important. If you dyno your ko3s at say 220bhp you should be able to dyno a ko4 all else considered equal to 250bhp. However, if someone else dyno's 220bhp in Ireland and you put a ko4 on you may or may not dyno 250bhp.

Thats interesting to know, Keith. Most people on here (myself included) think the k04-001 is only a older model k03s and not actualy a upgraded model.

The k04-001 is the same fitment as the k03s right? Not the same fitment as a k04-023?

Correct, the ko4-001 is a direct fitment to cars with a ko3s as standard. It will fit all transversal 1.8T engines except the 210-225hp models.

 

[Keith@APR]

Researching it further, it seems at the prescribed boost levels in the meat of the efficiency island the ko4 and ko3s will perform very similarly.

Its at elevated boost pressure above 1 bar that the ko4 maintains its ability to deliver 1 bar much higher into the rpm's than a ko3s.

This explains the increase in hp.

Regarding peak torque, it looks like the ko4 is again able to shine at higher boost pressures where the ko3s looses too much efficiency and superheats the air beyond the control of even a front mounted intercooler. This means you are able to spike the turbo to a higher pressure, 24-26psi, without blowing a bunch of hot air and therefore making more power than the ko3s can since you can only spike it to 21 psi max before it gets way too hot.

I've only ever seen the ko4-001 as an aftermarket turbo by Borg Warner sold as part of their Airwerks line of turbochargers. If you have a vin or year and model of a car you think the ko4 was standard, let me know and I'll check ETKA for any supercessions.

Nice info, Keith

hey there!!!

i know that this is a very old thread, but i still have some question.

Keith, does a K04-001 will fit also a k03 on a AWD engine code of a Golf MK4 2000?
if yes what do you think of The Kinetic Motorsport RP Turbo K04-001 with a Kinetic Motorsport 1.8T Hi-Flow Turbo Manifold

i already have a typhoon CAI by KnN and Forge DV007, i'm looking for a FMIC, silicon TIP, Silicon Boost Hoses, Silicon Vaccum Hoses 3&5mm. what do you recommend more for a k04-001? and what i'll need to change?

will a Forge TIP of k03 fit the k04-001?

After changing my turbo i'll go to an APR maping i have 2 dealers in Lebanon, but do i need a custom Map then?

many thanks in advance.
