hey guys I need some help I bought a 20g turbo a few months ago and since then I can't get no more then 18 psi on it i tried anything I have a EBC and all connections are right and it works good as long as is less then 18 psi but when I tried to go higher my turbo just don't hold the boost and just run worse the turbo is a TDO6 20G
mod list are :
WORKS flash
HKS 272 cams
680cc fuel inj
SPEARCO front mount
lower and upper IC pipe
3" down pipe,cat,
HKS Hi Power
DNP exhaust manifold
255 LPH walbro FP

 

 

Have you done a boost leak test? Also, what waste gate do you have? I have the Forced Performance and I had to preload it.

 

make sure your ebc is set to the right setting, not wastegate boost, but bov boost, or what ever its called. Another memeber had this same problem..

HTH

 

if you know what you're doing with the EBC then it is probably the wastegate. mine was weird like that too for my 16g and it would also not boost more than 18psi. check the turbo

 

Sounds like the wastegate. Thats were I would start first.

 

yeah I already ordered the FP westgate actuator I will be getting it next week and installing it as well, and yea I know what I'm doing with the EBC I used before with the stock evo 8 turbo and it was working fine.

 

boost leak test it right fast before you take it apart..............but yeah sounds like a wastegate problem if anything....

 

I will check for boost leak but I just got done installing the lower ICP

 

i have a similar problem, but why do you guys think its the wastegate, a lot of people are saying it but what is wrong with it.

 

OK... this isn't that difficult to troubleshoot...

1. Boost leak test. This is the most likely culprit... get it done and test it to 25 psi or more

2. WGA... it may be opening too soon, either because of a faulty or incorrectly installed EBC... if you can put the boost system back to stock or if you have an MBC, you can confirm this.

 

I will be putting my stock solenoid in anyway is set to 21 psi wtih the flash I got,rechecked all the wiring and my car runs smoth and kick's good now but just can't go over 18 it does go over if I want to but wont hold it at all will spike all way to 24 I did already but don't hold it not even a second!! I will make a video of it to one if this days before I do the new wastegate!!

 

check wastegate, do a boost leak down test and check your ebc

 

did you ever find the problem

 

always 1st check boost leak , then check westgate solenoid .
