EGR and Anti-lag (depending on use) are the same thing. The EGR version is more friendly to the mechanical parts then dumping fuel into the manifold/turbo. You get the same effect though

 

dude just drill it out, and buy an aftermarket one to cover it up

 

dude just get a small drill bit and drill the center of the bolt and insert an easyout. Then take a tap and re tap the thread with some penatrating fluid, get a new bolt put some anti-sieze on it and reinsert just snugly

 

That's the plan, but I need tools which are at work.
Anyway, what the heck is an 'easyout'? We might have something similar but prolly call it different... Is it like an extractor? It's a sort of a drill but not quite.

 

Yes

 

I recommend always putting a little anti-seize on EVERYTHING. Especially on spark plugs.
It will save you alot of headaches in the long run.

 

so who's actually taken off their heat sheild and left it off? I thought bout it. because it's ugly. I hate it.

 

The heat shield is there for just "in-case" you have a major downpour and your manifold is red-hot.

 

yeah that it

 

Is that all it does though? I thought it would protect the radiator and other bits from the heat on the turbo and stuff?

Anyway, the stock exhaust mani looks worse.

 

uhm... this isn't quite right... the bosses are there to feed the misfiring system air so the retarded spark will actually ignite the retarded fuel. no air means no bang bang.

this part is mainly talking about how if you don't run the antilag tuning hten it keeps your egts cooler becuase it spoots cold air in there. it also makes the transient response better because it's spootin' a lil air in there giving you the "affect" of antilag as the guy said above, altho this effect is quite miniscule and is nothing even close to the real antilag.

it is indeed the antilag system. in fact this is the best way to implement antilag and this is why it is present on non usdm evos because of the homologation requirement. they just omit the tuning and spray the bov air into the manifold.

egr is not hte same thing as antilag and dafarmer's question was that of hte legitimacy of the bosses, which i confirmed.

egr stands for exhaust gas recirculation and is a smog device that recirculates your exhaust air back into your engine during light load and engine braking conditions. this allows the car to save gas becuase no air means no combustions needed and also prevents new emissions from being formed, because if you heat up some fresh air you'll create more emissions, if you heat up air that has already been heated, then you're not creating any more emissions than you already did.

 

From what i have been reading the bosses don't really do any thing on the street Evos since there is no ECU control over the ignition timing at lift throttle. Sorry I can't speak from 1st hand experience

 

i already said that...

also for future reference... try not to say too many misleading things in one thread...

just FYI and the reason why I said "depending on useage"

As far as saying misleading things, I think we are talking about the exact same thing just in different manners.

 

When I did something similar I used a in-and-out i picked up at craftsman.

Basically, you drill a pilot hole right into the bolt. Then you drill just a little bit deeper. Then you use the special drill bit that will hook up to the broken bolt head and pull it right out, saving the threads.
