W115 / 220D turbo aplication ? - acme-115 - 10-12-2009
Hi everybody, this is my first post here.
I have read a lot in this from since 2 days. Great info here, thanks for establishing such a forum.
My dad has a W115 / 615 220D bone stock with 4 speed iron body transmission. We are restoring it, as a gearhead I have jumped into turbo aplication. I have a used Audi A4 1.8 K03 Turbo laying on the garage the specs are as follows:
Air Inlet 1.75"
Compressed Air Outlet 2"
Turbine Housing Flange Standard K03
Exhaust Outlet 3-bolt
Cooling Oil and Water Cooled
Working Pressure 6-25 PSI
Compressor Wheel 36 /50mm
Turbine Wheel 40.50 /45 mm
Works for Audi A4, Passat with 1.8T turbo engine
same unit here;

air inlet diameter seems small to me but im not an expert on this calculations.
Is this turbo suitable for 615 engine? Or if I install it what should i expect Lag? weak top end perf ? any input will welcome.
thanks.
Burak.

Check out my old car I put a turbo kit on my 1980 240d from a 1974 220d you will most likely need to keep the throttle body on that older style engine though! The biggest issue I have is my turbo is to big to old and has no waste gate on it so boost is late and lower than I want!!! The turbo I want to fab in to this kit is a k03 k04 out of a VW tdi or IHI out of an old subie 1.8

thanks for the reply.
I have read all your post about rajay turbo before I post here. Me and dady watched your you tube videos as well.
My first concern is: if my Audi A4 Turbo is good to go or not. in other words; K03/Audi turbo feeds by 1.8 gas engine ( higher rpm than my diesel but lower on the volume) I guess 2.2diesel can fill the K03, but the intake side inlet is kinda small to me ( compare to upgrade turbos recomended in this forum) I wonder if my 615 engine breathe easily with this narrow air inlet?
Throttle body is another issue, for the M pump fuel supply determines the engine speed , so why do I need the throttle body too? confused here.
I have found little more detailed specs of my turbo:
1.5" Inlet, 2" compressor wheel to intercooler
2.5" Outlet 3 Bolt standard, fit VW, Audi 1.8T Downpipe
Journal Bearing
Internal Wastegate at 12 Psi
200 HP Capable
Compressor Wheel .36 A/R
Ind: 35.70 mm
Exd: 49.10 mm
Trim: 52.8
Turbiner Wheel .87 A/R
Wh Dia: 40.2 mm
Trim: 81.9
Maybe it hepls a bit.

The K03 is too small. By 3800rpm the turbo's compressor efficiency will be below 60%.
The throttle body IS the governor for the pump. There is no link from the accelerator pedal to the injection pump. Like a g@s engine, throttle plate position (venturi vacuum) determines injection quantity.
Running the engine without the throttle body will result in a runaway engine.

Lol
runaway engine I got your point ; thanks for warning.For the small compressor inlet, is there a chance to swap only compressor side ? or should I swap shaft and pals too?
RE: W115 / 220D turbo aplication ? - willbhere4u - 10-12-2009
From what I have read the older injection pump is capable of some tunning but you could swap to a newer pump off a 240d OM616 and eliminate the throttle body as I did I would think the ko3 could support a 615/616 easy it is smaller than the 5cyl by about 20% it depends on how much boost you really want to run they make 65ish hp with out push 10 psi and some fuel and your looking at 100-110 hp but some very usable TQ numbers! I'm looking for a smaller turbo to spool up earlier so I can get max boost by 2500 rpm right now I'm starting boost after 3500 after the car has missed the power band! suck good luck!
RE: W115 / 220D turbo aplication ? - ForcedInduction - 10-12-2009
A K04 would be a much better match.
RE: W115 / 220D turbo aplication ? - willbhere4u - 10-12-2009
hey forced what do you think about this turbo IHI RHB5 (VF119011) Its off a Subaru legacy turbo 2.2 there is one at the junk yard I work at for cheep

(10-12-2009, 07:20 PM)willbhere4u IHI RHB5 (VF119011)
That would be good. At 10psi it would be right in the middle of the map where its most efficient.
RE: W115 / 220D turbo aplication ? - acme-115 - 10-15-2009
Thanks for the info.
I have checkd with the turbo shop, we will up grade the compressor side or trade the turbo with bigger one.

good luck with your project keep us updated and take some pics as you go along with it!!!

Thanks pal,
the car is in body shop, I ll paint it as soon as sheet metal job has done.
Today we started dismantling engine ( god bless chevy 350, MB engine is harder to work on)
i ll take some pictures as well.
