PSI on T3 Turbo
 

I have a T3 and just got a b16 del sol. I was going to install the turbo kit on it but i know the internal wastegate is set at 10 psi. I dont want to risk the chance of blowing my engine. I heard that with a boost controller you can only set the boost higher not lower than what it is wastegated at.Is that true? What can I do to lower the boost to 7psi? Thanks

it is true that the boost controller can only make the psi higher and not lower than what the wastegate is already set on.

to change the psi on the external wg i know u adjust the springs hehe internal uMm...haha no clue =(

Yeah, adjusting the wastegate spring would help. 10 psi shouldnt blow your engine though...you could chain your wastegate open but that would give you jack ---- boost

Just lengthen the actuator rod on the waste gate arm.

HOw much do i have to lengthen the rod? is there any other way to lower boost?

Re:PSI on T3 Turbo
 

how do you know the wastegate is set at 10 psi?

Re:PSI on T3 Turbo
 

Get a new external wastegate...

Re:PSI on T3 Turbo
 

could you cut the spring on the inside of the wastegate so it would be shorter and open earlyer or make it weaker by shaving alittle of the inside of the spring out?

don't do it because i don't know im being inquizitive

cant you just use an adjustable one from a dodge or saab t3? You could get one at the JY for like 50ct..
