Get the heat shield out of the way. take the O2 housing off. Check the wastegate. Make sure its not stuck/cracked open. Check the fins on the turbine.

If everything checks out ok. Do a compression check. Doubt thats the problem, but its a fast easy thing to check.
I have checked the fins to the turbine when i pulled off my intake, fins looked good and there was no play. It's not the cat because I have a test pipe. And the MAF plug is in tact.

I'll get back to you guys later, thanks for the help.

IM NOT telling you to do this, but one time i was racing my car and i was down 8mph in the trap. i did notice my boost was bleeding all the way to redline. didnt seem that bad but the loss of mph was.

I didnt have the tools to check for a boost leak...so i got pissed and just pulled the vacuum line off the actuator. (wide open waste gate) Knowing i did this i should of hit like 30psi fast....hit full throttle and i only piked 22psi (not quickly). I had a boost leak.

But if i was in your situation and i did the same thing, and it did spike 30psi, then i would think i hooked the EBC wrong or the solenoid was bad.

Well, I was able to get up early and get the car on the lift at work. I removed the lower heat shield and this is what I found.





Oh well. I'm just gonna replace it with a forge unit once I tap it out. I just have some crap luck with cars.

Thanks for every bodys help.

I guess our assumption turned out to be correct!!

Edit: I'll talk to Hugh later, you might be able to salvage the hotside if you're lucky, but I'd suggest ordering a new WGA in the meantime..

More exciting news for me today.

I guess this may have had something to do with some of my issues?







Notice any thing missing?

wow.....That is crazy. I told you that you would need a new hotside. Glad you found the problem. Now get that bad boy fixed and back on the road and feel the boost again.

Yeah, I have no idea where the flappers went.

Oh well, the car is at AMS getting all this BS fixed. I had em do the head gasket and some cams and gears since I was already there.
