Ok lets put it this way I had a wizaired intake, 1.9 rockers, ported blower, 180 thermo, 104 plugs, 3"dp, zzp pcm and have about 7* of knock. So with your mods and pulley you are just asking to blow it up then have to look for a new block. Either buy some supporting mods or take the smaller pulley off. You need to scan bad.

If you had that much knock with those mods you have a REALLY bad tune. You don't need to throw mods at a car to reduce knock. Just tune it properly and you will get results.
