Default N249,SAI,EGR delete

after following the thread over at vortex done by savwko(mike) i removed all this junk...its crazy tho that the 225 intake manifolds have only two vac nipples on them..so now i have a direct vac line for my R1 DV and sadly have to tee the FPR for my boost gauge... but i figured the DV would be a better choice...havnt driven the car yet so i know im expecting one or two codes but i rather have a better running car and not have some stupid solenoids controlling my dv. and the amount of space that is free'ed up is amazing....and not to mention makes the engine bay look a lot cleaner

Andrew,

Could you link the DIY for this procedure? As Some of you may remember; I did an accidental "N249 delete" a few months back when I pulled my manifold to polish it and install the silicone vac hoses. I accidentally snapped off the nipple on the bottom of the manifold when doing some work and ended up pulling it out, polishing it up, welding a new nipple on it, and installing it all back in... but not before snapping yet ANOTHER nipple off. This time it was the nipple on the N249 solenoid.

I just rerouted the vac hoses around the N249 and disconnected it (still haven't had a CEL come up yet). I would LOOOOOOVVVVEEEEEEEE to get rid of the SAI/EGR too; I hate having that huge "Clusterfukc" as nate would say... sitting on top of my engine.

So yea.... hit me up on the DIY and I'll pull that crap this weekend when I finish putting in the second nozzle on the W/M kit.

Oh btw... on a side note (completely unrelated), can someone please PM me and tell me why everyone started ******* bashing the snowperformance W/M kit now?!?! I swear to God... when I bought my kit... everyone was bashing devil's Own... now (even though still nobody else has bought one)... everyone is ****** bashing snowperformance. Whats the deal? I happen to like my kit.

no i dont think removing the pcv is that great of an idea....since it helps relieve pressure in the crank case under WOT...at least thats what im told...mechanics...lol

I know we ned relieve pressure in the crank but that ' Y ' pipe under manifold is know to leak ...
I thinking about doing it that way :

Hey Andrew,

How long did this process take you?
As you know... I'm no stranger to pulling **** off my car for no reason just to see if it will still work without it... but what does SAI and EGR stand for? I know the EGR is that clusterfukc of crap on top of the head that makes it so impossible to make the 225 look neat.

Default RE: N249,SAI,EGR delete

it will take about an hour to do it all...the hardest part was getting the SAI pump out without removig the impossible to remove bracket...the N249 is the solenoid near the dipstick under that black cover infront of intake manifold...that stuff is the clutster f&ck over the three coilpacks...also the EGR is exhaust gas recirculation...bascially now the car wont recycle the exhaust gases its gets in and gets the hell out...that wasnt easy to remove cuz those damn allen head bolts stripped on me and i had to drill them out...make sure u have the 1.8t block off plate from 20squared to replace the egr....and i have no idea if im gonna throw a code or not....i havnt started it up in forever...i just did my timing belt because it was two teeth off and the new one i just did is now two teeth off....have no idea how the hell that happend but ya big waste of time cuz i gotta do it again....its complete BS the belt didnt jump or anything...i guess it wasnt a wate of time cuz i had a fairly new waterpump in there and guess what it was plastic!!and yes it was broken..so at least i got a metal one in there now....

SAI = secondary air injection
EGR = Exhaust gas recirculator

Both work to warm up your engine/cats faster, and burn any excess fuel vapors you might be dumping to atmostphere.
