You need to address the leak between the exhaust manifold and the turbo. As long as it's there, exhaust gasses will escape and won't be able to spin up the turbo to make more boost.

Even the smallest pre-turbo leak can hurt performance. The fact that you can see the leak means it's robbing you of a lot of power and spool.

That crack you had in the mani was pretty friggin' big. How did you fix it?

I drove through West Sac yesterday... would've stopped by but I was dead tired. Off to Dublin for two weeks tomorrow. I'll give you a call when I get back.

So last night, this morning and this afternoon I was noticing alot of smoke comming from my breather that i have on my Valve Cover. What would cause this? Its smoking alot from there. Even at idle. Could this be from Detonation or ping? I dont get it, Im only on 3-4PSI of boost and I still detonate my friend said. the mods on the car right now is the greddy td04h, 1.8 injectors, and the 2.5inch cat back. So i have no idea why i would be Detonating or pinging.....But im thinking thats why it was smoking from the valve cover. What do you guys think

Why do you have a breather on there? Is it just a filter? You need to route that onto the suction of the turbo to allow a vacuum on the crankcase. This will eliminate the problem. Post a pic of you under hood.

Bipes aint on, timing is on six. http://i21.photobucket.com/albums/b2...ai_turbo-1.jpg that is without bov and with out the breather. is the smoking bad? And one last dumb question, i have expericned detonation before, and it just stops pulling and it kinda vibrates, can it detonate even while it pulls hard?

yes it can detonation isn't always readily aparent in power delivery if the detonation gets bad enought to studder the car you have a major problem and detonation event like the one that killed my motor at 13 psi with a failed WI system all the sudden fix yuor AIT's withb a IC or WI or something you are killing the motor.

So even though im only boosting 4 i would need an ic? even tho the greddy kit comes with none and your suppose to boost 5.5? Dam it. I guess ill chill out til i do then. time to start savin up for the stripes kit i have encountered an oil leak again. ill have to figure out that one now. And why do I need to hook up the valve cover breather to a vaccum? I mean...Whats the diff.

Do you not read anything on this board? The one thing that people stress the most is attaching a vacuum line pre turbo inlet to the crankcase breather. That way it relieves pressure in the crankcase allowing the oil to drain from your turbo easily. Other wise pressure can build restriction oil drain flow which in turn will blow oil seals and all kinds of bad ****. It'll cost you about $3-4 to do it.

Vacuum in the crankcase does some really good things for a motor. It causes the rings to seal better and helps the turbo to drain the oil. It also gets rid of all the gasses that are in the crankcase and keeps the motor oil from changing ph and making it eat away at the bearings prematurely. I would route it to the intake of the turbo, after the afm. The stock greddy kit has the fitting to do this. Most people do not have good experiences without the vacuum in the crankcase, just for your information. I would definately do that and see if that fixes some of your problems.
As far as the AIT's are concerned, An intercooler or WI will definately help you with the detonation. I added WI to my setup and was able to run 12 degrees of base timing at the stock greddy boost. This is my car, so yours may be a lot different. I just redid my head and got rid of all the carbon that was in the chambers which really helped the car to make more power.

well you obviusly have some kind of issues i dunno what but colder air would help you. ESP if it is carbon build up raising compression, faulty timming settings, cloged injectors, weak coils, obstruction in the exhaust, and so many more things that could be wrong with your car. I might not have a greddy but i know a thing or to about FI either check all these things or put some cooling to it. and check those things. Most people dont take the mantanence of a FI'ed car as serius as they should this is sad. :(

Sorry Bro. Never read that. I guess the breather is going off...And when you say Pre turbo inlet, do you mean before the fins? I mean, inbetween the afm and the turbo?

between the AFM and turbo tap a fitting in there and run some line to it. Also the PCV over the intake could use replacing with the 323 gtx pcv to prevent boosting into the crank case. Also did you use the greddy drain scheme if so then you might think about tapping the pan or look to make sure it is truely all downhill and no backlogs can occur.
