how are u getting 14 psi with a stock ecu BOV and straight exhaust? do u not have a mid pipe or a cat or sumthing? i think ur turbos are spiking which can eventually cause damage to the car

baf

it's boost creep cause no cat(no pre cat jdm one) just thrust muffler.The cat was block but anyway i'm not running with the car until everything is repaired

and then its not going to run at all.... lower it to 10-12, and you'll be in much better shape

baf

i can't lower it to 10-12. i have to port the wastegate or putting a cat on it.So it's gonna be an pfc and a non-sequential conv.i'm on the way to buy alu. rad. and fmic so i'll wait to run it next year but with a nice set-up.

You could also put in an exhaust restrictor. It took care of my creep issue right away. It will hold be off until I get the wastegate ported.

baf

yeah i haven't tought about that!!good idea do you know wich size i have to make for the restrictor?

Just installing the pfc isn't enough. Stay out of the boost until your TUNED for 14 psi, or you will regret it. In the interim, you should consider re-installing the stock cat or at least a restrictor plate.

baf

i know about tunnig.lol It was implied when i told to ''install the pfc''
I don't have the cat..I empty it beacuase it was block...I just want to know wich sized is the restrictor plate have to be...

14 psi won't hurt anything as long as you stay under 4K rpm

Remove the wastegate restrictor pills, it should keep the car around 8-10psi. Ive never seen one have overboosting issues with the restrictors removed.

You can keep running 14lbs though and I will gladly sell you a shortblock

baf

yeah sure thanks for the help i will check that!

With no cat, the car will still overboost/creep with no pill (not "pills" since there is only one) in the wastegate line.

baf

That's what i tough.Anyway if i can find the size of the restrictor plate i have to make i'm gonna do this tomorrow by the time i will get everything to tune it at 14psi

You buy many restrictor plates and then you keep going down in size until it is controlled. Should be between 2.5 and 2.75 ID.

baf

thank's i'm gonna try that.I'm gonna make them it's sy to do!
