Mercedes w123 om606 - soltysrsz - 10-31-2014

Hello!

My first post here i just wanted to show you guys my Mercedes w123 swap from om616 to om606 with 717 450 gear box.

Sorry form my English is a bit weak since I’m from Poland.
First I leave the chassis to fix all rusty panel, whole car is going to be painted with original colour Big Grin

Some photos how this car looks like before fixing rust:

New alloys for my car:

New intercooler

Holset h1c :

All bodywork should be finish in next week, we will see Shy

New engine:

Here I have question, which motor mounts I should use, w126 om603 or w124 om603?? Any of them would be pnp ?? or I need change sth??
Regards
Rafał

RE: Mercedes w123 om606 - erling66 - 11-01-2014

That will be a nice car when it is done Smile

One week to fix all that rust? good luck.
Great idea to keep original color.
H1C should work fine, but what size is the exhaust?

RE: Mercedes w123 om606 - Druk - 11-02-2014

Sweet. I'm using the 717.450 box on mine and it's a peach. What clutch/flywheel do you intent using?

the car is being repaired for 2 months, the guy should finish in next week. the biggest problem for my are motor mount. stage one is put motor to angine bay and start it with om603 ip. stage two is made custom exhaust manifold for holset and 7mm section and 3'' exhaust, mabey 4'' downpipe and 2 pipe 2,5'' we will see. in stage one i have om606 n/a clutch and flywheel because i want mount ERL
what clutch and flywheel did you use?? i wonder how strong is this gearbox and om606 n/a clutch an flywheel?

Small update, body work is almost finished. some photos:

when car will be in home, we will try to fit the engine and gearbox

RE: Mercedes w123 om606 - Tito - 11-25-2014

Thats al lot of work... Big Grin

I did a 603 in a w123 and I could use the original right enginemount. I used a 13mm thick plate to realign the mount. It was about 1cm left and up when looking at the pattern on the engine.
left engine mount was a diy.

RE: Mercedes w123 om606 - soltysrsz - 11-26-2014

thanks for information, i have 2 types of engine mounts, one are from w126 and the second are from w124. I have found information about motor mounts on this site :

http://mbturbo.com/enginemounts/

RE: Mercedes w123 om606 - soltysrsz - 12-22-2014

The car is in the garage of my mechanic. We have putted engine in engine bay, we used w126 engine mount with spacers. They fit the best in my case Smile

, but we need to cut gearbox mount, w124 gearbox didn't suite to this mount Sad

. For now i'm waiting for painting whole car. What i should do with ip?? use old sections 5,5 or change it to 6mm?? And how strong is om606 n/a clutch an flywheel??

Regards,
Rafał

RE: Mercedes w123 om606 - sassparilla_kid - 12-22-2014

I think the elemts from the electric om606 pump are 6mm and can be fit into the 603 pump for a little more fuel, but not 100% sure as I mostly play with 616/617 engines Tongue

RE: Mercedes w123 om606 - 97e300 - 12-26-2014

ok, server with my old photos is working now Wink

jupi, so i can upload more photos. As i said, engine is in engine bay with damage oil pan Sad

, which oil pan i should buy ?? can i buy om603 or m103 oil pan?? What i should do with throttle linkage?? how it should looks like??

as sassparilla_kid said, i will convert my ip to 6mm sections

photos:

RE: Mercedes w123 om606 - soltysrsz - 01-13-2015

Small update: we have fix oil pan Smile

, everything suit correctly. We need to make gearbox linkage to change gears and make linkage to accelerate pedal.

Yesterday i polished turbo pipe Smile

RE: Mercedes w123 om606 - Ksteen2 - 01-14-2015

you can use the 124 mounts, and drill a new hole att both sides to bolt it..
but the best is to use the 124 att the left side of the engine, and make one att the right side self.
you can offcourse look at my 606 into 123, its a hole thread of how I did it Smile

done it three times now, two 606 and one 603 into three different 123's Smile

Thanks for information Ksteen2. Friend i need information what clutch i need to use in my car Smile

. OM606 na clutch is 228 mm so i bought 240mm sprinter clutch and pressure plate didn't suite to my flywheel Sad

, it is small difference with bolts. I think to buy sprinter flywheel dual mass. How strong is it?? Later i will change turbo to holset and 7mm sections, it will holds. If not,what flywheel and clutch i need to use ??

RE: Mercedes w123 om606 - soltysrsz - 05-06-2015

Small update, car is in paint shop Smile

another w123 with om606 Smile

ready to paint

i ordered used mercedes 2,2 cdi valeo kit and new pipes to inter cooler Big Grin

maybe in next week we will fire up engine with 6mm ip Dodgy

. When car will be ready, i will order better ip and new outlet manifold Big Grin

thanks Ksteen2 for your advice

RE: Mercedes w123 om606 - soltysrsz - 06-11-2015

Small update, car is painted Smile

painted and polished alloys :

maybe today we will fire up an engine with 6mm ip for now, it is possible to suite bigger turbo for oem exhaust manifold??

RE: Mercedes w123 om606 - Keino - 06-13-2015

I like that you painted the ronal pentas same colour as the car. Very cool Big Grin

16x9 et14 rear and 16x7 et23 front?

RE: Mercedes w123 om606 - soltysrsz - 06-14-2015

i would rather have pentas or bbs rs, but for now it is perfect Smile

rear:
16x9 et13
front:
16x8 et11 i think

RE: Mercedes w123 om606 - soltysrsz - 06-27-2015

Small update :

RE: Mercedes w123 om606 - Torkey - 07-22-2015

What do you plan on using for the clutch/flywheel?

RE: Mercedes w123 om606 - soltysrsz - 07-24-2015

(07-22-2015, 05:22 PM)Torkey What do you plan on using for the clutch/flywheel?

Hi Torkey i will try to use 2,2 cdi clutch. First i bought om 606 na clutch but now i have single mass and clutch from valeo to 2.2 cdi.

Maybe in next week car will go to mechanic and we will fix issue with suspension, brakes etc..

I've been thinking about doing a build similar to yours. I have found finding a clutch, flywheel and transmission difficult here.

I have the same problem with buying this parts, it takes me a lot of time Smile

, but i am thinking of buying bmw gearbox, it is a lot stronger. Maybe i this week we will finish suspension and brakes.

RE: Mercedes w123 om606 - pryantcc - 07-29-2015

Clutch kit details here:
http://www.superturbodiesel.com/std/showthread.php?tid=5554&pid=63534#pid63534
No issues if you're using a mechanical pump.

I don't know how wel lit would cope with crazy HP though.

RE: Mercedes w123 om606 - Druk - 07-30-2015

My 717.450 came from a 320TE W124 that I broke. I kept the DM flywheel, clutch and cylinder from the donor and all that fitted to the 606 with no problems. All I did was get a (supposedly) heavier duty friction plate from a place in England. The clutch is nice to operate, very soft in fact, and it's still working after three years careful driving. I don't do Grand Prix starts and the engine is standard with 6mm elements in a manual pump. BTW, it's pulling a 2.28:1 diff and it does this easily.

RE: Mercedes w123 om606 - soltysrsz - 08-01-2015

omg i thought that gearbox is strong and could hold about 350 km, for sure i need to buy a stronger one, but which gearbox i should to buy?? only bmw gearbox is strong enough?? For now we have big issue with brakes then we fix issue with suspension.

today my car came back to the house, a small video as rides.

https://www.youtube.com/watch?v=0fP0vJC5ZM0&feature=youtu.be

my mechanic tried to put W126 diff but we have a problem with the axle shafts. We checked with the W126 and W116 but they are to long. Can I mount the LSD of the Mercedes w124 320 ??
The next week I will try to do to the car exhaust and the ic pipes

Poland, Wonderful roads Big Grin

No exhaust systems? Sounds loud Big Grin

But hey, it runs! Smile

RE: Mercedes w123 om606 - erio - 03-03-2016

I have a w123 carlsson replica. Find it on youtube carlsson classicauto.
Come may 1-3rd on monday to kielce trackday. Ca cup.

I have a w123 lsd cusom made. Gimme good w123 diff with axles and i will put lsd in it.
I also have c32 brakes 4 piston calippers and 340mm disks in w123. I can make you same adapters to bolt on callipers. All made in poland.

Smile

GL and stay in touch.

RE: Mercedes w123 om606 - soltysrsz - 03-10-2016

hi Erio, thank for your help. i don't thinks so that diff will handle such power. I would like to mount w126 diff, it is better for me, but i have problem with axles. in this month i 'd like to buy new mufflers to my car, i found 3'' magnaflow mufflers, 13219 and 13743 it would be enough to my daily car?? Now i fixing problem with rust bolts.

340mm disks will fit to 16'' alloy??

RE: Mercedes w123 om606 - erio - 03-10-2016

i have 16 inch steel , and 17 inch alloy.
but i use 30mm spacers front and 50mm back.
..I wouldnt know if itfits without spacers

RE: Mercedes w123 om606 - soltysrsz - 03-17-2016

small update, i chose magnaflow mufflers:

Erio i have 16'' alloy, et is about 11, so here can be the problem.

RE: Mercedes w123 om606 - soltysrsz - 10-21-2016

Smal update:

Car is running great, but om606 demage my clutch and turbo is leaking, so i wondering which turbo i should find. I would like to have no smoking setup with 7,5 mm pump.

Which turbo would be the best, my goal is about 400 hp:
-holset hx30 and holset hx35
-holset hx30 and holset hx40

another problem, which turbo should feed another turbo? small should feed bigger one or viceversa??

Regards,
Rafal

RE: Mercedes w123 om606 - R-3350 - 10-21-2016

i would go with the HX30 and 40 they are better sized for compounds. however i would look at other turbos too. the Holset's are geared towards higher pressure ratios at a slightly lower flow in the bottom of the map. with compounds you're not too concerned with the maximum pressure ratio of each turbo but the mass flow and the sizing relative to each other. as for the plumbing the exhaust is routed into the small turbo then from the outlet of that into the big one. you will need two waste gates too. one going from before the small turbo into the pipe feeding the big turbo then one from the pipe feeding the big turbo to your down pipe. the intake is plumbed similarly the big turbo draws air from the air filter then compresses it and feeds it into the small turbo. if you can fit two intercoolers one between the turbos and one after ( technically thats one intercooler and one aftercooler) that improves the performance. but the space in the bay is limited so i would probably just run one after the small turbo.

RE: Mercedes w123 om606 - soltysrsz - 10-23-2016

Ok, thx for your advice. I have found holset hy40u. It would be enought for this power? This turbo was used in Iveco Stralis Cursor 8. And another question in which car i can find hx30 super? I'm guessing it would be the best turbo for me. My injection pump would be set to 120cc.

RE: Mercedes w123 om606 - R-3350 - 10-23-2016

the HY40U is a HX40 with a smaller hot side. in the throat feeding into the turbine there should be a number stamped or cast what is it? that turbo will probably work but it might be a bit small for compounding at least if you want to run smoke free at WOT. the HX30 super is kinda rare i haven't heard of people pulling them off of anything. i would message Alcaid about getting one he sells factory new Holsets.

now for the fun math. at 120cc/1000 it works out to 0.102g per injection event. to run smoke free and low EGT this means you would need 1.836g of air in the cylinder in order to burn the fuel cleanly at an AFR of 18:1. an om 606 has 499.3 cc per cylinder with air being 1.29mg per cc at STP this works out to 0.64414g of air in the cylinder with no boost. this means you need a density ratio of 2.85:1 in order to supply the air. this is of course assuming 100% VE and a variety of other variable im not factoring. to get the 2.85 density ratio assuming decent intercooling of around 80% you need 31.5PSIG boost however there is the restriction of the head, intercooler, plumbing, and air filter to work around so lets just say 35 ish psi (or 2.4 bar) should do ok. the next issue is the turbo sizing im not entirely sure of the flow capabilities of the HX/HY40 however the above calculation requires ~60lb/minute at 6000 rpm running 2.4 bar while the 40 could do this i suspect not at the low pressure ratio it would see in compounds. this is similar to the size im currently looking into at least in regards to mass flow vs pressure ratio requirements. i might look into a Borg Warner S300SX-E series for your LP turbo it handles more air at a lower PR than most Holsets can at that same PR. also remember with compounds its quite easy to simply increase the boost to feed more air. at least if you size the turbos with a bit of head room. for example with both turbos running a PR of 2.0 it multiplies the stages so you get a PR of 4.0 or 44lbs of boost. the issue is the mass flow you're trying to pull a lot of air through the LP turbo at low pressure most turbos don't like that so you have to size carefully.

anyways feel free to cross check my calculations. im not as familiar with the 60X engines and by no means assume i didn't make any mistakes. good luck on your build it cool to see a good w123 getting a new heart and more pep.
