What could it be. I just got my 89 turbo supra 3 days ago. I knew it was going to have problems I just wasn't sure what and thats one. Also I have no blow off valve on it right now. Yes, I know I shouldn't be romping on it but I just couldn't resist. I am waiting for my hks bov. Well give me some info guys I'll be out of town for a week so when I get back I hope I'll know what to fix
