i just got my car back together last week and i now i have a problem with my boost. it wont boost over 4 psi and i was wonering if anybody had an idea. i think it might be a small leak somewhere. i double checked all the vacum hoses and all the lines coming to and from the turbo and there all fine. i was just wondering if anybody had an idea on what it could be.

 

what wastegate spring are you running and are you running a boost controller. need to give some more information in order to help you out

 

i am running a 9 pound spring and no boost controller

 

How is the spool rate? Same as before or slower?

Probably a boost leak.

 

could be a exhaust leak b4 the turbo , or boost leak in the charge pipes

 

thats what i am hoping for is that is a charge pipe. but i will look at it later tonite after i get off of work.

fixed it it was a boost leak in the charge pipe

 

are you running a FMU, and what injectors do you have, my buddy had a 6:1 FMU, and stock injectors and had the same problem

 

Is the car popping around 4500-5000rpms?

It could be you are using the wrong plugs that are not gapped properly.

Where or which charge pipe was it? cuz im only hitting 5psi and i have a 10psi spring! so i have same problem, it might be loose in the same area

 

its actually a tear in the connecting piece from the trubo to the charge pipe so i have to replace it. it still does it sometimes it will boost and sometimes it doesn't. but i also think that it might be my waste gate because i dont hear it open at all.

 

same here

 

now that i got my charge pipe fixed now i have anothe problem. i have a 9 psi spring but i will go past that and i dont have a boost controller can anybody tell me why this is happening

So, you are over boosting? How much? Is it just spiking or holding steady at a higher boost level?

I would be careful if I were you... overboosting can be the end of your motor

 

im not for sure what it goes to but it was at 11psi and i backed off the gas. so i dont know if it stops there or keeps going.

on a FMU...

 

Maybe your wastegate is stuck or something... is it internal or external?

 

wastegate is probably stuck. my buddy's t25 on his sr20 was doing the same thing.

 

i will check my wastegate tonite after work its an external wastegate and im runnuing a vafc. is it possible that the spring broke.

 

I bet it's fun though

 

yeah its pretty crazy but im scared to blow my motor.

I don't see how the spring could break but I would inspect the wastegate to make sure it's working properly...

 

might be sticking. Do you have a vac line connected to the top barb fitting of the wastegate?

 

yeah
