Hey guys,
I have a r32 with an rb20det and an rb25 turbo. The turbo blew up and i replaced it with another rb25 turbo. Ever since replacing it the boost pressure wont limit itself. Anything over 3500-4000rpm causes the boost pressure to spike. It got to around 15 psi before i backed off to avoid damaging the turbo or other components. I have a turbosmart boost tee installed which was set to 12psi before swapping turbos and worked perfectly. After this issue i wound it right back to see if that was the issue but im still having the same problem.
Any ideas on what the problem would be?
