Hey guys
I was trying to set my boost today, and as i was driving it went up to 20 pound for a split second
My cars a rb20 silvertop with r33 turbo
It is now making a loud wooshing noise like air is pushing out, it is still generating boost but stops around 6-7 psi, but i have the rb20 actuator so it should be around 11 or 12
Would my turbo be blown, or just a major vacum leak?
I have checked all the intercooler pipes (but it is night, so i can't see everything), but nothing seems to be wrong
any ideas?
Also idle is very rough and jumps down to about 100 and back up constantly
Thanks for any help
