ok i had a stock 13b gslse engine on my gslse and im using a blow thru turbo setup with it, well a friend of mine told me that to use NGKs B9EV or B10EV, well i was using B10EV but now i switch and i put a street port 87 turbo II engine with the same blow thru setup because my other engine blew but my question is, can i use the same B10EV spark plugs or should i get different ones? any recommendations? and another thing, i had the timing at stock on my old engine and was running 11 psi, im expecting the same psi with this one, should i put a different timing setting or leave it stock timing?. thanks
