I’m about to put on my turbo kit but I have two problems that I have been trying to fix before the turbo goes on.

First thing ever since I got the car with the motor (by the way it’s a 91 civic si with a b16) the spark plugs have always been white with a little brown in them from what I under stand that’s not good for a turbo application. I do have both the o2 sensors one in the bung on the header and one in the test pipe. I haven’t set my timing so I don’t know if it is advanced I will be setting it to about 14 digress when the turbo is put on.

The next thing and this just started happening about three weeks ago. At 7000 to 8000 rpm there is a hesitation I have a MSD digital 6 with a SS coil stock plug weirs. I have tried new plug and weirs and it still doing it I don’t know what to do.

I would really like to get this stuff fixed before I put on the turbo kit.

Thanks for the help

maybe your coil is going bad. Or you have a lose wire somewhere under the cap.
