-------------------------------
edit:
Logs: (how to use -> first scroll down to be able to
scroll across. Find a spot then scroll up to compare)
note, RPM top graphs
and inj duty and inj time on bottom graphs values on 2nd Y-axis FAR right.
even with only 4psi, I'm running lean. I wouldn't have thought that. You can see the increased MAF readings.
------------------------------
So, I believe it's about time I start my 2.0T build thread.... it's a lot to type and I'll be editing this first post several times so I don't have to get everything in at once.
I'm putting a stock 1.8T k03s on a mk4 2.0L engine so I can utilize much of the stock 1.8t parts (DP/CAT, etc). In a MK4 car I could also use the intercooler setup, but I'm not, thus the twist.
Tasks I still need to complete before installing:
- mounting 1.8T AIT sensor in intake
mani - done
- massaging stock 1.8T oil feed line to fit
with coils in place - done
- coolant return line - done
-
cleanup grinding on mani - done
- fab a heatshield between exhaust
mani/turbo and underside of intake mani/TB - deferred
1) I know the k03s is small.. My goals are small to match.
2) I know
the mani is restrictive, best I could do with the space.
3) I know it's
non-intercooled.... plan on wai
Pics:
early mockup
drilled and tapped block for stock 1.8T turbo coolant feed line
(this motor is already in car)
drilled/tapped block for stock k03 support bracket.
later, more complete mockups (lastnight)
still need to bend/tweak stock 1.8T turbo oil feed line
around 2.0L coil. I've got the 1.8T oil fitler braket in
the car that has the hole for the line.
using the 1.8T PCV
hose for head breather. The Y has a blockoff, but I'll later run a hose from
there to the top of the oil filter braket for crankcase venting. I'll just
plug/cap the metal tube coming of #4 runner.
Tried using as much stock OEM hosing as I could. White nipple on far right is
for the stock 2.0L injectors - fresh air hose.
stock 1.8t turbo
coolant feed(bottom) and return(right)
Diverter/Blowoff hose with Tee for watstegate. The Tee is a 1" - 5/16" - 7/8"
that is from the heater core hose on fire wall on a 1.8t.
vac/boost line from TB with a 90* elbow to stock diverter and a small tee for
boost gauge (not connected yet). 
extra nipple off TB hose for one-way check valve to feed vac only
systems
big hole of left is for brake booster, hole to the right and slightly lower
is a first attempt to mount the 1.8T AIT sensor with a
helicoil for sensors mounting bolt in an existing bolt hole. After drilling the
hole, I find that the tab is webbed/hollow on the under side preventing the
sensor from being air tight. Good thing this is a practice mani (damaged)
plan B, having a bung machined and welded to mani where marked.
stock 1.8T DP/CAT
waiting patiently

Cool man, that's gonna be dope! Did you make that exhaust mani yourself?
I want to get me one of those valve covers, i have the black AEG one and I
hate the oil filler thing, it's really loose and doesn't seal
well.

I did everything but weld it. Designed it around tubes availabe from McMasterCarr and given space restraints. CAD drew it and had flanges waterjet cut. I did weld up a 'jig' for the welder so the flanges were in the right positions.
Added a little detail to first post^^^

Well I went out and bought material to cut/bend up a heat shield today. Then I thought I just see if the stock 2.0L heat shield could be chopped to fit, and what do you know? So, I'll take a cutoff wheel to the stock heat shield tomorrow.
Also, I may relocate the vac source for the brake booster and try to use the
old hole for the AIT sensor.

When I decide to go into FMIC required boost levels, then I'll consider a TIP. No need for one with my current goals.

That's a good question.
Before I say, what does the community think a
non-intercooled k03s 2.0L 8v is good for SAFELY.
I'm thinking as a NS-Charger alternative.

Update: I hacked up a 2.0L exhaust mani heat shield, but it sits right on the
mani... literally. I'm worried expansion from heat may create some undue forces.
So, after all that I'll go ahead and cut some aluminum sheet and bend up a heat
shield.
Also started to cleanup the mani with some grinding. WHAT a PAIN. I got one
runner port matched and it took forever.
AIT sensor in bake booster hole, but now where to drill/tap a hole for
mounting bolt.

ok NON of the cars in those links were mking 240, most were under 225.....your buddys car is not a standard stock + car...ie chip intake exhaust fmic... he has stage 2 tuning, more timing, more fuel. more of that power is coming from the advanced timing and fueling of the motor, not the pos ko3 turbo, which by the way is pretty much maxed out at 225... sorry dude a ko3 is a ko3. very small and designed for economy... and on a 1.8L to boot

his car was pulling timing because he was overcharging his turbo... when the turbo passes the efficiency range its just blowing hot air, its hot to the point that a fmic can compensate and the car pull timing, he either A needs to turn down the boost, B retaaad the timing a bit, or C get water/alcohol injection and be G status like me
im sorry but vdubman runs a t3s60..... a turbo that will easily push out 300 hp

It's really an AZG engine controlled by an AEG ECU. Why? AZG for low mileage and oil squirters. AEG for DBC and lack of immo.
Furtunately my goals are no more than a neuspeed supercharger (for
now).

finally finished port matching exhaust mani:
I'll have the AIT bung welded to the intake mani by Friday hopefully.
I'm going to wait on doing the heat shield, just so it's not holding up the install.
Oil feed line is tweaked.
I needed to order a few little pieces (banjo bolt, washers, etc). So, I'll
have to wait for those to come in.

Now this is nice!
I remember seeing a cast manifold on ebay some months ago that allowed you to bolt the KKK turbo's onto the 8V cylinder heads.I believe you have stumbled across a hidden art because there are so many unloved AEG/AZG's out there it isnt funny

Thank you.
Some CAD shots of mani.... I changed it up a bit by using the
#3 runner Tee as the down neck to turbo and 3/8" turbo flange instead of
1/2".
Straight welding of tube fittings sourced from McMasterCarr.
Very little
cutting.

edit: Oh I get what you're saying....
I designed it that way for a reason. It places the K03s in the exact same position as the 1.8T. So, one can use all the stock 1.8T parts and bolt them right up to their 2.0L mk4 cars.

As I stated before, the engineers @ VW felt fit to place b/w the exhaust mani and the intake mani / TB sitting right above in it's N/A form. If anything, it will help protect the TB.

Before install. (2002 2.0L AZG and 02J swapped last
year)
removed intake and PCV. disconnected throttle cable and vac lines
2.0L intake
removed upper intake mani. tape over lower mani to keep debris out
removed 02 sensor from 2.0L exhaust mani
car raised to get to DP/CAT
disconnected 2.0L DP/CAT from catback
now to unbolt 2.0L DP/CAT from exhaust mani
2.0L dp/cat(bottom) out next to 1.8T dp/cat(top) 
moving post cat o2 sensor plug from 2.0L dp to 1.8T dp
lower car and now back up top. removed 2.0L exhaust mani
didn't come out clean, snapped a stud.
and a stub from exhaust mani flange came out with nut. But that's not a big
deal.
plugged SAI port. (top right on mani)
I lied when I said I had the 1.8T oil filter bracket in
the car already. I found out I had installed it in the wagon, not the mk2.
Here's the 2.0L oil bracket. No hole for the stock 1.8T oil feed line.
1.8T oil filter
bracket with turbo oil feed banjo hanging out the front.
1.8T oil filter
bracket installed. I wish it was a straight foward as these pic portray.
dropping the turbo down before I install mani.
I had to snake oil feed line in before dropping turbo. Here it's bolted to
turbo.
2.0L 8v -> k03 mani
installed
turbo mounted to mani
taking a break to eat

Finished up. Car started and idled.
turbo oil feed line bolted to oil filter bracket
botling turbo support bracket to block. I drilled and tapped these holes
before I swapped the engine in last year.
just a shot of k03s from below. notice I have the wastegate ALWAY open for
now.
oil return line done. needed quick hands when doing this when car is full of
oil 
oil return block off plate that I removed
now for the 1.8T dp
install. raised car again
dp bolted to turbo
pre cat o2 sensor relocated and installed
another fast hands moment. removing coolant feed plug bolt with turbo coolant
feed line
done. hands not fast enough... all wet
TIP installed
DONE! car was idling in these pics.
That's a wrap!

just back from a drive on the highway. But I was just letting everything get good and hot. I'm NOT running any boost right now. I've adjusted the wastegate to always stay open. I'll go thru all the exhaust bolts tomorrow to make sure they're tight. Drove like stock as expected, but I did hear the diverter valve open
.

Good stuff.
Suggest: hook up a temporary (or permanent) boost gauge so you
actually
KNOW where the boost is going.
The ~partly open wastegate valve will not completely keep you out of boost.

i hit 10psi by 2400rpms and 15 by 26-2700... i think that it's ridiculously
torquey and LOVE EVERY MINUTE OF IT...i can not imagine how much faster the damn
k03 is gonna spool...i'm
gonna go head and guess 10psi by like 2k! 
also i'm running 8.5:1 compression....

looks a little more than 'slightly' to me. How os it on the top end? (highway)
What psi do you run, or plan to run to merit the compression drop?
Logs: (how to use -> first scroll down to be able to scroll across.
Find a spot then scroll up to compare)
even with only 4psi, I'm running lean. I wouldn't have thought that. You can
see the increased MAF readings.

as far as my setup...i currently run 20~21psi and she holds it jus fine. The

hmm good to know...well here's the issue...the ecu is still able to compensate for the air flow coming in and keep it around the specified/requested a/f....best bet is to either A: get c2 software with 30# injectors B: do the dreaded rising-rate fpr C: get lemmiwinks or unisettings or custom settings and add fueling under increasing load. or D: get 30# injectors as thats what 1.8t essentially have

Seem as though k03s @ 4psi is good for a ~18% increase in air flow.

Be VERY careful.
This 16.32ms 'cap' is a ecu data block limitation.
i.e. the data the ecu
sends to vag-com can NOT go above this value.
I'd bet a few dollars you're running more inj. duty than you believe.
This ecu DOES NOT have wideband fuel control...
there is NO live fuel
trimming under Full load here.
Be VERY careful.

So, inj. time could be higher in reality.... but it could NOT be lower or the ecu would show it lower, correct?
On the 0 boost example, if it were higher, then A/F would be
richer....
But I don't see a need for it to be richer. i.e. the 16.32 valve
seems logical. Cowencedence?

Thanks for bringing the MBC by Pedro!
I've finally finished installing the LC-1 WB controller. I have output 1 simulating the stock pre-cat NB O2 for the ECU. And I have the output 2 showing full AF from 0-1v on post-cat O2 line. I'm not using a post-cat sensor.
So I can log true AFR on O2 post-cat voltage
3psi = 12.5 AFR (+ 4bar FPR). I'll now start to raise boost slightly until
AFR starts to lean out.

I have the post-cat bung plugged. There is no sensor after the cat.
I
have a Wideband sensor before the cat controlled by the LC-1.
The LC-1 has 2
output signals that I can program.
Output 1 -> ecu in place of pre-cat NB (0-1v) sensor, programed to simulate a NB that the ECU uses.
Output 2 -> ecu (wired) in place of post-cat NB (0-1v) sensor, programed to send full range of AFR from 0-1v instead of the narrow switching range around 14.7 like a true NB sensor does.
1 WB sensor feeds both per-cat and post-cat signals to ECU.
So, now I can have the ECU act normal, AND log true AFR on post-cat
voltages.

I can program the controller to output anything I want. Since the ECU only expects a 0-1v signal from the post-car o2, I programed the WB controller to scale down the WB 0-5v to fit in the 0-1v range.
i.e. 0-5v 0v = 5 AFR ; 5v = 22 AFR
now 0-1v 0v = 5 AFR ; 1v = 22 AFR
output 1 feeding ECU for pre-cat O2 signal: (narrowband)
output 2 feeding ECU for post-cat O2 signal: (wideband on a 0-1v
scale)

Well, I relocated the AIT sensor to the mani in hopes that the ECU will adjust timing back a bit under boost to avoid having to 'retard' timing.
It seems to have worked, BUT it also seems to lean the mixture due to the higher temps..... I'll switch the AIT back and forth to confirm.
If it is true.... then I'm a little dissappointed.
Post
Title: Re: (elRey)
Posted by: elRey at 1:29 PM 4-17-2008
After some logs last nights it does look like ECU leans mixture when AITs are high. I switched back and forth between AIT locations and:
- MAF (pre-turbo) ~12.5 @ WOT but timing is being pulled via knock sensors
- mani (post-turbo) ~ 15.5 @ WOT but minimal timing pull (relative to above)
edit: also notice @ part throttle in boost a was ~15 AFR and O2 reg was off. It was only with near to full thottle that it richened up.
Logs were @ 6psi.
Again, I'm on stock injectors + 4 bar FPR.
