I just put an exhaust manifold and o2 housing on my evo. the car is stock other than bolt ons. I'm only getting 10psi. I dont have any boost leaks. Whats going on?

 

what brands of parts did you go with? what parts do you have? what did you have to remove to do the install?

 

sounds like a massive boost leak running wastegte pressure check the vacuum line running off the wastegate for holes

 

Both parts are MR. I have an injen intake, injen upper and lower intercooler pipes, and Buschur TBE. To put the manifold and o2 housing in i had to take the turbo out of the car.

 

bump

 

Either you have a boost leak, the wastegate signal line is hooked up without being routed through a boost controller (stock or aftermarket), or you have a huge exhaust leak before the turbo.

 

+1 for exhaust leak

 

I would go back to the manifold, loosen the nuts and then re-torque them from the center then right then left, ect until all have been torqued, then i would re-torque the bolts and nuts at the turbo to manifold.

Did you mess the the wastegate arm when you put the o2 housing on?

 

I didnt mess with it. But the whole turbo with the wastegate was out of the car sitting on my work bench. Ill try the exhaust leak but if there was a leak there would be carbon around that area and there isnt any. I appreciate everyones input
