Default T28 Replacement

Need some help please guys. I'm replacing the T25 turbo for a T28 but not sure where the pipe between the turbo and the actuator goes. On the T25 it connects from the front of the turbo but on the T28 there is nothing to actually connect to, or am I missing something?

Old T25

New T28

you just need to tap that into any charged vacuum line.

Most people will put a valve on the silicone coupler they use and attatch a vacuum line to that.

it must be charged, and the closer to the turbo it is, the better since this is the signal for your wastegate.

Cheers for that, I've got a ca18det and have the BOV plumbed into the valve on the side of the block. If I put a tee on this will that work?

um...yea, but from what I understand, you want a strong boost signal. by the time it's reached the engine, the pressure drop has gone down at least 2psi...

If you can't find anywhere else then there is a spare nipple just behind the throttle body you can use
