problem with boost

[iatebananas]

Hi all. Ill cut it short. I'm driving a kancil l2s with rhf4 turbo. The turbo was consuming a lot of oil till the point that it got into the intercooler and tb. I changed the turbo to another rhf4 unit but it is not boosting at all. The turbine is spinning but only boosting 0.1 bar on full throttle. The rhf4 that I swapped didn't look the same as the previous one... Any ideas?

Perhaps issues with actuator or wastegate?

consumed oil is the turbo gone edi, need rebuilt...

cant boost check all boost lines for cracked etc, wastegate etc

could be the issue.. I experience this before... my car only boost till 0.4bar...
'tulang ikan' already fully opened... later change actuator and boosting till boost cut..


the first spoiled turbo you use manage to get over 0.5? or same with new one?
