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 in but my question is, can i use the same 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

My opinion regarding the timming if your not sure would be to take it to a good rotary workshop near you and put it on the dyno for a proper tune, don't do it yourself....



Just a quick question, in your .sig you say that your have 550cc injectors and 680cc injectors..

Yet you say you have a blow through turbo setup in your post there? That would imply, to me at least, that your running a carb? ....carbs don't have injectors in them though...

opps sorry, my bad, i need to change that, is because i was trying to put the turbo II ecu and wiring harness but didnt work, im gonna change my signature later on, is just i keep forgeting, but i have a 45 dcoe weber carb tuned by rotary shack, SE dizzy and street port turbo II engine

the gslse runs 13.75 degrees over 2000rpms at wot, should be boost safe?

and about spark plug, should i run the B10EV's or different ones?
