Hello all, I have a greddy turbo kit that i am going to putting on my jdm gsr motor. From what I have found so far I know that my motor is 10.6:1 compression and that the stock wastegate on this greddy TD05H-18G turbo is 0.50-0.60kg/cm2 thats 7.5 to 8.5 psi. what i was wondereing if there is any other wastegate that I could use with this setup to lower the spring pressure to more like 5-6psi and control it using the boost controller from there.

bump...........

 

is that correct??

 

still need help

 

good question how much psi is on the stock wastegate ? 7 or 8 psi my car has an 18g on it and im boosting at 12 to 14 psi on the stock wastegate with no boost controller somethings wrong ? im also getting what feels like boost cut at about 4500 rpms at WOT but if i only push the pedal half way and keep boost under 10 psi i can rev through fine any ideas ?? and yes im running a 3 bar map sensor and my ecu is chipped for it i was thinking a bad wastegate actuator......

 

A 6 year old thread... Really?

 

would u have rather me start a new on dealing with the same question ******

 

No, we would rather you do your research.

There is no "one size fits all" answer.

 

i did research couldent find an answer so i brought back an old tread
