Deleting EGR with "Kit" [Anyone's]

READ this Biblical Length Post FIRST !

Blocking Off the EGR will force the EDS
(Electronic Diesel System,the engine computer) to Kill the Boost from the Turbo.
UNLESS you follow GSXR's instructions for WG replacement.

The Kit "On Offer" is certainly Nice and functional...

BUT,I like My Kit with Stainless Steel Plate, Bolts and Gasket
that came with the Ultra Copper High Temp sealant and 1/16" thick Copper Disc.
That I may have gotten,
from someone who might have been in a State contiguous with N.J.
Who,in an Obverse universe,might have been CB.

Bonus Info:
The Turbocharger will not actually produce "Boost" until it's "under load".
I.E. All systems are operational, the Tranny is in Gear and your right foot is doing it's assigned job.
(Watching the Compressor Vanes Pinwheel with the engine running Ain't "Boost".)

Y'all will please note the "Zoomed" picture (Number 5 0f 5) of mikeyfav's reply#21
It's showing the Intake Port on the Pressurized connector that runs
between the Turbocharger and the Crossover Pipe that feeds the Intake Manifold.
[The EGR uses that port during Warm-Up, Idling to INJECT the NASTY CARBON CRUD from the exhaust into
the Intake to control emissions. (Counter-Intuitive) ]
The little circle that looks Blocked with Nasty Black EGR exhaust dust mixed with oil is exactlywhat it looks like!!!
AND you can bet your last dollar the Inside of:
The Crossover Pipe,Intake Manifold and anything downstream of the EGR
ALL LOOK EXACTLY LIKE IT!!
This be the reason to Test the EGR by blocking it off for "Off Road" purposes Only!

If y'all REALLY wanna enjoy the full benefits of the Wastegate/EGR Delete,
Take the Crossover.Connector and Intake manifold Off and clean them.
Any part of the Sensing system's Tubes and Ports,ETC. should be cleaned also!
I have found that the easy thing to do on the EDS equipped engines (well at least the '91 300D 2.5T) is to just put vacuum to the wastegate all the time. Unlike the 617's, the WG is normally open, NOT normally closed. With vacuum to the WG all the time, the car has all the power the engine can give, and runs great (kinda like a "greased cheetah chasing a bullet train"). I know some folks will balk at this suggestion, but I don't know what to say, other than it works. Changing the actuator is a big job for some, so this way is much easier. I know that the only over-boost protection you have with this method is in your right foot, but it has been my experience that these engines do not get close to an over-boost condition very often (if ever). Maybe when they were new and all the systems were in perfect working order was that protection needed. Always remember in situations like this: "your mileage may vary"- just sayin'........Rich
