Hi. I have a 1994 civic with a d15b7. I am using a rhb5 turbo. It has a internal wastegate. I think it is for 8 psi but I am unsure. It is stock. I have a spot on my manifold for a external wastegate. my question is should I put a external 6psi on it. I am worried about the internal one working correctly because I had to turn the housing. Even though I put the internal back on just bolted it in two of the other holes. Should I be worried and get a external? I dont want to blow my engine.

Here is my setup.
D15b7 Engine

OBX manifold. Rewelded.
dsm 450s
VAFC Hack.

Please let me know what to do.

the internal should be fine. rotating the housing doesn't matter. that wastegate doesn't have an adjustable arm on it. right?

Right. There is no adjustable arm.
