OK my talon does not have any overheating problems whatsoever and never has and still doesn't but my manifold and turbo glow red when i drive the car for about 10 miles. its not the waste-gate cause im running a wide open waste-gate at all times. so what could be cause them to be getting so damn hot? i also have brand new oem plugs and wires on it and its getting plenty of fuel and oil and coolant are flowing just fine... so what could it be. the new plugs were kinda white after i ran them for about ten miles so what does this mean??? what the hell is going wrong with my car cause im about to junk the bastard if it keeps giving me shit!!! someone please help me before i lose my damn mind!!!!:cry::banghead:
 
Check the torque on the Exhaust to manifold to turbo and your manifold to the head. I had a similar incident cause I had a small exhaust leak. The only other thing I can think of is either blocked exhaust, or you are running your car REALLY hard early..

Have you BLT it?
 
Are you driving it like you stole it every time you take it out? What kind of engine management are you using (AEM, Link, AFC, Stock ECU)? It sounds like you are probably running lean to me.
 
Is that 10 minutes of hard driving? What boost level are you running? Do you have a wideband o2 sensor? If so what are your AFR's? Need more info. A glowing manifold in certain circumstances is somewhat normal. However it can also be a sign of running hot (lean) which is bad your engine (detonation/knock). Let us know some more info and we can go from there.
 
its got 272 cams and arp pistons but thats pretty much all the internal work thats done to it. everything is tight on it and i have a 3inch apexi dunk strait through exuast system on it right now so there is no blockage.

all the rest of the engine is stock except for a few minor things and the 16g turbo.

Never assume... I know of a couple instances where flex pipes have collapsed internally, causing a huge restriction on 3" straight through pipes.

Not saying that is likely the case, but it never hurts to check.
 
and no thats not hard driveing thats completely normal driveing. i dont run my car hard.
 
and if im running lean then why is my car still getting up and going fine?

I just looked at your profile and it says you've got a 16g along with that 3" exhaust. That sounds like a recipe for boost creep so back to my question, do you have a boost gauge and if so what boost are you running?

Never heard of ARP pistons, are you referring to ARP head studs? Lol!
 
well hell im just confused and it could be normal but it just starting doing this but it still runs like a bat out of hell!!!
 
i turned my boost down to 10lbs and i was running 20 and yes i have a very expensive and extremely accurate boost gauge

so how do i fix it from running lean then?

So you were running 20 lbs of boost with a 16g on your stock 450 injectors? Even though you've turned that boost down now you could have done some serious damage with it at that level. Have you done a compression test lately?
 
yes on stock injectors and i don't have the tools to do a compression test.

ok look. i now how my car is supposed to run. i now all about fuel and compression and air fuel mixtures and boost and ecu and blah blah blah. the only time a turbo and manifold should glow is when the car is overheating and my car is not overheating so whats wrong with my car? and i no for fact its not fuel and its not cooling system and its not blockage in my system!!!

You should be able to rent a compression gauge from auto zone.

Heres the problem with throwing a bigger turbo and raising the boost on a car without the supporting modifications done to it. You run a lot of boost which causes your engine to run lean because you are not getting enough fuel (because your 450's can NOT compensate for 20lbs of boost). This causes knock (detonation) inside the combustion chambers. This can destroy your head gasket, rings, pistons, bearings, etc. I would do a compression test ASAP just to make sure that you haven't damaged anything yet.

Assuming everything is fine with the compression test, I would go back to the basics. You already have a "very expensive and extremely accurate boost gauge" so next I would get a wideband o2 sensor and keep that boost as low as possible until your get a tuner/logger and larger fuel injectors. Then I would follow this: Tech Guide: 2G 4G63t Upgrades - DSMtuners for your future modifications.

Hope this helps!

Out of curiosity, what spark plugs are you using?
 
Your saying that after a 10 minute drive of notgoing into boost the exhaust manifold and turbine housing are orange? In this case running a 16g on stock injectors isn't relevant, if he's driving it for 10 minutes and never going into boost the 450's are fine. If the car gets up to speed just fine I also wouldn't assume theres any kind of restriction in the exhaust either. It seems like a faulty o2 sensor would be my first check...

:dsm:
 
im using bpr6ekn ngks witch are the most recommended sparks plugs for our 4g63t motors. and im using 8mm maxx performance spark plug wires>.
 
ok guys well ive been up all night trying to figure this out so im going to bed. if you guys find anything else out about this problem please dont hesitate to input cause i will be back on around 5 or so. thanks guys.:thumb:
 
It seems you want someone to tell you what's wrong with your car without you wanting to even check what is suggested, and just assume stuff is correct. An overheating car is not going to make your manifold glow. Even 300 degrees is not going to make iron glow. Your car is either pulling mad timing, or running too rich or too lean. Since you don't have a wideband you are just assuming that your car is running the correct air:fuel mixture, but 20 psi on stock injectors will make a manifold glow pretty nice.

WRONG. BPR6ES is the suggested plug, and you want them gapped to .028" - .030".

It is like he is waiting for an answer he WANTS to hear. Like: "thats 100% normal; why don't you turn the boost up to 25psi on that stock fuel system"

OP: you have not answered any of the questions. I am assuming that this is 10 minutes of hard driving since you said it:
"runs like a bat out of hell!!!"

A glowing manifold/turbine is normal under peroids of hard driving. However, in your case it does sound like it is running lean. You should think about turning the boost back down until you can upgrade the fuel system and get a logger/tuner/wideband.. like suggested.
 
And he said he was running 20 psi but doesn't drive it hard, but sorry, you don't hit 20 psi driving around normal. I see leanness and pulled timing. Pulled timing really does more than anything to make a manifold glow quickly. The burning is being delayed and the fuel is still burning on its way out. The plugs are white so it can't be rich, either. He obviously doesn't know all about fuel and compression and air fuel mixtures and boost and ecu and blah blah blah. You can only be helped if you accept it. Just assuming things are working without checking them will get you nowhere fast. We all do it time to time and the things we usually assume are totally fine are the things that turn out to be broken.
 
You're either running lean or have a timing issue, no other way around it... i would start with checking and setting the base timing.

Well based on the fact that you were running 20 psi on 450 injectors id have to say that you sure weren't putting all that knowledge that you have into practice. If you truly knew "all about fuel and compression and air fuel mixtures and boost and ecu and blah blah blah" then you would have known that your injector IDCs would have been maxed out (fuel) and you were running very lean (AFR) causing knock and pulled timing (ECU).

In this case running a 16g on stock injectors isn't relevant, if he's driving it for 10 minutes and never going into boost the 450's are fine.

I heard him say that he was driving normal it and it was glowing. I also heard him say:

well hell im just confused and it could be normal but it just starting doing this but it still runs like a bat out of hell!!!

i turned my boost down to 10lbs and i was running 20 and yes i have a very expensive and extremely accurate boost gauge

so how do i fix it from running lean then?

Which is not exactly:

and no thats not hard driveing thats completely normal driveing. i dont run my car hard.
