Do it up like this:

The bottom part of the Hallman is the input the side part is the output

Thanks...why experiment !!!

What I was questioning is the merit of using a tee on the input to connect the boost ports ( green line ) of each turbo.
The T2 uses a fitting on the housing as the pressure port to the actuator
Probably won't make a major difference.

Hope to install it in about two weeks.

Ok time for some updates.

It seems i either blew a piston ring or cooked a piston on my car, i still haven't opened the engine, so now car is off the road for a rebuild.

I also happen to have a smoking turbo as the rear KKK k16 seems to be on its way out again.
So i have made up my mind to go for a single turbo setup. i have found a guy here who will chop my stock exhaust manifolds and weld them up in log style manifold. I know this is not the best of designs for efficiency but still considering the tight space it should work.

I have found a Garrett turbo T04 with an A/R 0.60, no i still have no data on the flow rate for this turbo but if its too large i might go for a Mitsubishi TD05- 16 G large as this flows at abt 43 Lbs so it should be good up to 350 crank hp.

As for the front mount inter-cooler, for the time being am going for a w202 230K one, and considering that i have the alcohol kit already installed i dont think i will need more cooling, just hope this intercooler still flows at 13 psi.

What’s more, oh ya if i find a dog leg first box i will also be installing it. I expect the car will be off the road for some time so i have decided to get my self a C36 AMG 1996 mod that is in mint condition and for a very appealing price. Deal should be done by mid next week.

they have started working on my car, unfortunately they couldn't have the engine out yet, and since i'l have the 36 amg tomorrow i am not pushing my mechanic to rush the work. it'll give me time to save abit for the bill heading my way.

A large bill as am also converting to a single turbo, ie i have a lot of custom fitting to do = more costs.

Am also seriously considering a six speed (no luck in finding the dog - leg box yet) manual from the M111 cars, thou my mechanic is runing scared from the idea :)

am told the six speed box will set me close to 900usd, so its still a pending idea, as am sure to be looking at a 2000usd bill as it is.

you probebly shouldnt have advanced your timing and then upped the boost, normally you go the other way when upping boost.
good idea on the single turbo, you are joining the club :-).
i run a t3/t4 ar:63 hybrid turbo with internal wastgate on my car, 2.8ltr m104,
it is a garrett copy turbo but has caused me no trouble, check them out.

bet ya it was makin some serious power before it went pop tho! when you are that close to detonation that you melt something is when hp is made

that is why people go for forged, alot stronger against that, not bullet proof but alot stronger

i had a similar problem on my car, but it was only at 6 pound, it leaned out and pop, my injectors wer to small i have since upgraded to 440cc.
i just put in another engine, turf the old one out, also gave me the chance to uprate the clutch to one that can handle more power

Well guys, i still haven't opened up the engine, but unfortunately i have made up my mind to return the car back to N/A form. so the kit will be off the engine and will not be going for a single turbo setup :S.

Its saddens me not to be able to enjoy my W124 in such a powerful form. but to have the car runing reliable and up to the way i usually abuse my cars, i will have to fork out alot of time , time , effort and last but not least money.

I will be rebuilding my engine wit maximum overbore i can have, and the head will get some minor work, all in the hope to have a faster than ur average M103. :) silly i know when you compare it to what the car was making before.

Any way i still haven't made my mind up to a final decision.

My mosselman kit is up for sale if any is interested:

kit includes:
- 4 X turbo KKK ( 2 in gr8 condition and 2 need a minor rebuild kit)
- top mount inter cooler with all the piping needed
- 2 x exhaust manifolds
- will help u trick your CIS to flow through out the rev range so as to avoid knock and lean spots. ( it took me hours on end to aquire this know how.)


if i dont install a single turbo setup, my high flow fuel distributor head is for sale too
- 1 x fuel distriutor head that will flow enough for up to 0.55 bar bost. ( that way no need to install anything else to have the car running safe)

am up for offers, i still have no set price.

yea flick off the twin turbo set-up, but you gota keep the benz forced! just run a slightly milder boost level for reliability, say around 10psi, youl regret going back to NA

i know man, and really haven't made up my mind, just spent the last 1/2 hour on the phone with my mechanic talking this issue over and over. so far i am still leaning to going forced, and i'll have support either way.

i just cant see my w124 N/A again, seems ill stick to a low boost and just love the car as it is.

i am just put off by the costs of fixing it, but what the heck, money was meant to be burnt :), and now i have the c36 to abuse on daily basis so i'll have the option of fixing up the W124 with no rush.
I want to do it perfect this time, and i am seriously considering a stand alone sys a few months later.

its hard going back to no boost, the power is way different even from a high hp c36.

the AMG can't even come close to the acceleration of the W124.

Jay

Stay with the boost....life is too short so you might as well go fast when you cross the finish line .

I still like twin turbos...looks impressive :)

Ed

Thanx Ed,

i most prolly will stick with boost and yes twins looks sweet and prolly sounds better, i love the low hiss of the twins, but i need to go single i don't like the mosselman way of doing things, your kit is way better thought of. but thats me, for looks the mosselman looks the business with the hood up, it catches ppls attention with all the pipes and the top mount IC.

and now that i have the AMG c36 i have come to realize how well built the W124 is. those cars where way over built. the elegance of the interior is just amazing. but you know that already as i see you have a C43 ( which btw has a good looking dash, atleast better than the old c-classes)

Jay

Agree completely...
I never liked the Mosselman especially the top mounted intercooler.
A single turbo is easier to do as a DIY custom install.

You could probably get a good price for your Mosselman kit...still desirable and better yet very rare !!!

Congrats on the C36..the W202 is as close to a 124 that you can get..
The 3.6 sounds like a modded engine should sound...!!!

The C43 is also great car..it's my wife's daily driver.
Very docile until you punch it.
But the boosted M103 is much faster then the V8 C43 !!!!

Ed

Jay, my opinion is open up the engine first, examine the extent of damage to the engine and then decide which way to go. Personally I think that you'll never again be satisfied with your w124 performance unless it's boosted again :D . If you choose to rebuild the engine consider aftermarket forged internals, sometimes they end up cheaper then OEM stuff and can handle a lot more power (of course if tuned right) .

Ed,
True abt the single setup DIY thing.
As for the 36, well it sounds gr8 especially over 5k rpm range. feels a bit gutless low down but prolly thats only due to the long long gearing on this car. and the fact that i am always waiting for the torque of my w124tt in third :P

this is exactly what am doing....

as for forged internals, plz point who to contact if you know, cause here in lebanon we cant find any. so any links would be gr8.

have you thought about roman? he may be able to point you in the direction for custom internals. just out of interest what was the sign to you that the engine was toast?
