Just picked up a 92 HB with a B20B complete motor B18B1 Intake mani, GSR tranny, GSR ECU. After about 7500RPM you can hear something kinda sound like
Shhhhhhhhhhhhhhhhhhhhkkkkkkkkkkkkk in the engine bay. The guy who we bought the car from said it's the valves on the stock B20B motor that they could not handle the rpms. Do you think that is the noise? Thanks for the help anything will help. Will try to post pics of the car asap. It's my cusins ride.
