Head Lifted!
Yesterday i installed a forge ball and spring manual boost controller on my car and took it for a ride where the boost controller only had like 4 clicks. I installed the MBC by on the side port goes to the wastegate and the bottom one to the turbo. Did a second gear pull n boom.. Car shuts off white smoke behind me where i cant even see. I pull over and see coolant dripping from somewhere but dont know where. Car still turned over constantly. It had stock head studs. Is this a big problem where i blew my motor? Or did i just blew my headgasket and have to get a new one with arp head studs? What someone told me was i boost spiked somehow but i have a stop map sensor so would it cut off at 11psi? Im going to take the head off today install the studs and send the head out for inspection. But if i fix the headgasket n all that my car should be back up and working normal right? or did something also mess up that i should look into?

Re: Head Lifted!
You should have started with the BC fully closed, and then incrementally upped the boost. This is assuming you have plenty of fuel and enough map sensor to reach the boost level you wish to see. Also, why did you not have boost cut enabled? Especially when doing something like this. If your ECU does not have that capability you need to be using a different tuning tool. You will also want to check your deck along with the head. Make sure nothing is warped. Hopefully everything turns out ok, do it right the next time and be careful.

Re: Head Lifted!
So i take it u dont have a BOOST Guage? so who knows how much u were boosting!! and yes stock map sensor stop reading at 11psi but it wont boost cut off at 11 unless ur tuner told it to!! so more then likely u spiked up words around 20 and who knows what happen! gotta pull the head and see whats going on! good luck! my advise, dont install a boost controller unless u have a guage and know what ur setting it at!

i had my head lift. not to the point where it blew white smoke but the temp kept rising at idle. replaced the headgasket and installed arp studs and didn't have any more problems

Did the car overheat at all? Correct me if I'm wrong but a head/deck will only warp if the car overheated and blew the gasket? I think you're safe if it didn't overheat, just do an inspection of everything when you take it off and replace the headgasket, get ARP studs and torque it all down right

Re: Head Lifted!
I have a boost gauge but i was watching my a/f when i was doing this. The car shut off right when it pulled really hard. N i pulled over right away n checked wtf happened n got the car towed home. If i blew the motor the motor wont even turn over. It turns over i think the only reason it wasnt starting was because the spark plugs were flooded with coolant. The car didnt overheat cuz it just shut off on my first pull. Im taking my head to get it inspected anyways for any warps. Only thing i may have to do from people tell me is to get the stud holes re threaded cuz i probably stripped them. I think i just blew my headgasket i dunno. Going to take everything apart tonight after work. I just want to know if everything else is fine n the car just needs a new gasket n studs n im set to go

You either lifted the head or cracked a sleeve from what it sounds like. You'll find out when you pull the head off. Maybe it just lifted since you had coolant blown out of the engine, but I'm not sure. Let us know what it is

Re: Head Lifted!
My tuner said i lifted the head cuz i have stock studs and they probably stripped. I had coolant all under my car i dunno where it came but my block had coolant every where the mani is.

Re: Head Lifted!
That sucks hope you figure it out. What size spring were you running in the wastegate? Just curious why you needed a boost controller with the stock map sensor. We all learn from mistakes though...

Same guy who was beating on his car with "low oil pressure." Funny because I was going to post in your other thread yesterday about how you'd probably have another thread up in a few days wondering why your motor was blown.

Re: Head Lifted!
does a head really lift? I just can't see it phyiscally lifting from the pressure the turbo is adding on top of the immense pressure of combustion. usually its just the headgasket on its way out anyways.

What you did was you installed the MBC wrong, more than likely you installed it backwards. You then experience as massive boost spike, went extremely lean, and likely cracked a sleeve and melted pistons.
Head lift doesn't push coolant out of the block, and it only happens during boost, overpressurizing the system and pushing coolant into the overflow. Read, head lift air goes into the coolant jackets, coolant doesn't go into the cylinders. What you have is catastrophic failure of some kind.
