Ask him to perform a leakdown to get some sort of diagnostic status.
Always a good idea.

thanks again, i just hope he has the equipment. any ways earlier in this thread i mentioned that blow by from the pvc issue, well now that i have dropped the boost to 0.5-0.55 bar this issue has completely gone. i mean i drove the car for like 30 min and even then with oil all hot no blow-by could be seen.
any ways i know i a going abt this all the wrong ways i can, thing is i work from 8 to 4 so all i end up havin is like 2 hrs at the end of a long day. and my mechanic being a friend kinda thinks its ok not have any work done except on few occasions.
i tell u never befriend ur mechanic, just as much as u dont want ur girl befriending her gynecologist-doc, lol silly comparison i know. well its been a long month to say the least.

Jay.
The blow-by issue is perfectly normal for a boosted engine.
Altho a remedy we use on high end boosted ones,might be an idea to ponder at least...
Check to see if you can increase crankcase ventilation area one way or another.

What we routinely do on the valvers is to open up the OEM fitting in the block for a mech pump just after the chain register as well as drill the OEM PCV fittings out as much as we can.

Point being that large area PCV outlets is a sort of mantra with boosted engines to me.
Stands to common reason that as dynamic compression ratio goes up....so does blowby.
If you opt to combat crankcase pressure iŽm sure youŽll notice a couple of things.
Oil consumption goes down,like in drops like a stone,and power goes up accordingly.

Just one of those small things that most people that boost their engines never get told about and that makes a difference.

Thanks man

Finally I have some good news, fingers crossed, turns out all the smoke is coming from the second turbo, the one I did not rebuild. It seems with no downpipes and thus no back pressure the turbo will not smoke no matter how u rev it. Just when the full exhaust is in place it will smoke. Any ways instead of ordering a new rebuild kit at 300 usd delivered, I did what I should have done ages ago. I moved my lazy ass and search every scrap place I know, and be hold I found a clean lovely kkk k16 turbo for a mere 50 usd. Yes its 50 usd now that’s cheap will be going back this weekend to get my self another 2 spares, just incase **** happens later on.
any ways, today I will pick up the car to start proper fuel setup. Fingers crossed again

guys, can i use injectors from the w126 560 to give me more fuel flow on my w124 turbo 300?
if no do u know of any larger injectors i can use on my car's ke jet sys?
(sorry for not posting any new updates the past few days due to the fact that lebanon was on in all kinds of trouble and on the brink of a civil war, dunno if we r on any of ur news, things seem to be cooloing down now thankfully and hope normal life will return by monday)

Do you have the fuel controller that was supplied with the Mosselman kit ?
If you do, it's adjustable and will allow you to enrich under boost.

Just using larger injectors will not give you the result you want as the EHA basically is controlling the amount of fuel to the distributor.

Thing is i dont have the mosselman controller, but i can change the flow of the EHA by changing the signal it gets, but i am worried that wont be enough for high rpm

That is exactly what the Mosselman controller did, except it was adjustable to obtain the correct AFR at boost RPM's.
It piggy backed to the stock ECU.

The Turbotechnics like I run resolved the enrichment by adding two additional injectors between the air valve and the throttle valve.
Control is with a stand alone unit so none of the stock settings are modified.




Stock fuel control and EHA doesn't know the engine has any boost...all the enrichment occurs downstream. Main signal for these two injectors comes from a MAP sensor.

I find this extremely practical as the vehicle will pass any required emissions tests, start up quickly, idle smoothly.

Ok, let me explain: for the time being i have a switch installed in place of the audio fader behind the gearbox leaver which i use to trigger the eha to a preset value. IE in off mode the EHA functions normally and in on mode the EHA flows more.
I am building an electronic unit that will trigger the EHA to flow at different levels depending on boost by means of a MAP sensor.
What i still dont know, and hope u do: does the mosselman unit triger the EHA using boost level only or does it read RPM too?
keeping in mind that i keep the control of the ecu over the EHA at all times IE all i do is offset the whole mapped values if u get what i mean.
Thank you for your patience,

Guys, after the installation of the turbo kit my auto box is now shifting harshly under light throttle even without any boost showing on the gauge. while on higher revs and more throttle the box shifts too smoothly, worryingly smoothly to the point that its slipping, but under a full revup shift the box is fine. keeping in mind that i have installed something similar to the attached.
Do you have any advise???

but i need ur help for ideas on how to flow for fuel, i already have the 2 pump system on my car, will a third pump do much difference

help with any ideas u have
thanx

You should be reading about .85 Lambda under boost to prevent detonation and get max power.

I still run the stock dual pumps as they provided sufficient fuel pressure.

What fuel pressure are you seeing....did you check the total full supply loop including the return.
