Dont boost that engine unless you have a GOOD TUNER and a good EMS system.
That engine is right on the verge of detonation anyways and by boosting it, you will blow it for sure.
You could probably get away with 5-7 psi with a perfect tune but that engine was never meant to be boosted...At the very least, put a thicker headgaskt on it to lower compression slightly...
If you wanted to boost, why did you go with the B16B?
