does the N/A have EGR?

i'm looking to do easy things for power. if a 96 3000GT base model has the EGR, i am looking forward to manipulate that.

anyone who can verify that would be great.

thanks.

yes, just about every car has EGR... EGR is easy to delete, and has a decent outcome, however, if you're in a state that requires emissions testing, i wouldn't recommend it

i just did an AF search before i get someone who suggests it first..

so i guess my real question is then what benifits come out of it?

cleaner internals is all i know of. any HP gains? i was confused because 3sx has the block off plates only listed under the TT exhaust section.

i live in florida.. no emission tests :-D

In theory, if the EGR is working properly, you shouldn't see any gains in HP for a N/A engine...

It's different with Turbo'ed engines since the EGR is used to control the exhaust temperatures even at WOT.

1st gens nas dont have egr do they?

pretty sure they do

1g NA's do NOT have EGR. 94/95 Fed Spec NA's also do NOT have EGR's.

Stealthee backing me FTW.:lol:

was unaware about the fed spec though.

ok, so 96+ n/a has EGR? and i'm guessing all vr4's came with egr?

...what is EGR?

What is Google? :p

EGR - Exhaust Gas Recirculation, basically it dumps exhaust gas into your intake to try to reburn any left over combustibles. It's for emissions. It's shut off under WOT (wide open throttle).

Yes all vr4's have egr i beleive.

EGR stands for Exhaust Gas Recirculation, and basicly it is another way that they controled emmitions, some of the exhuast would go through the engine again and burn off more impurities (in theory at least) but it can hurt power a little (more on the vr4) because it is exhaust gas so most of the oxygen has already been used.

correct me if im wrong stealthee:lol:

EDIT: Haha, Twisted you fast posting jerk lol.

All VR4's have EGR yes.

And yeah the Fed Spec thing. My 94 SOHC has an EGR because its Cali spec. MY 94 3000gt parts car has/had EGR because it was Cali Spec as well. My old 95 SOHC parts car did not have EGR as it was Fed Spec.

ok so what i can expect from removing the EGR is a higher engine temperature, at the cost of more pure air into the cylinders?

sounds good to me. has anyone done this?

i know the EGR crap is near the firewall somewhere. how difficult would this task be?

The EGR is there to reduce the amount of oxygen in the intake change so that the engine could run leaner when at partial throttle without increasing Nitrogen Oxides in the exhaust. (The main words being "PARTIAL THROTTLE").

You aren't going to gain much, if any HP at full throttle even if you remove the EGR off an N/A engine.

It's used slightly differently in a FI engine since the engine can overheat if you are using full throttle at full boost for a prolonged period of time (I don't know how long so don't ask) if it was a completely "fresh" intake charge if you are running at slow speeds (lost of start/stop at full throttle). In this case the EGR is used to dilute the intake charge to reduce the intensity of the combustion (this reduces power and why it's way more common a mod in forced induction engines).

IMHO it's a wait of time blocking it off/removing it in a NA engine.

In my opinion its a waste of time to not block it off. The EGR makes it a pain in the ass to remove the plenum for doing plugs/wires.

Okay, let me backtrack...

Blocking off the EGR is probably as useful as blocking off the resonator bottle in the intake. Unless you have a ulterior motive, doing it for HP gains isn't worth the work.
