Having issue with my compression on my 370 turbo setup.. I have a fully forged flat top motor with prc stage 2 heads (about10:6 1 ) compression and wating to run about 15 lbs of boost but tuner is having pre ingnition issue.. So looking at options. What old be the best benefits.. E85.. I thought about changing heads to some 317 with 71cc and a thicker head gasket.. To get compression down.. Would like to keep it on 93 octane if possible but will convert to e85..

Any water/meth injection? What heat range plug?

As of right now no..it's at the tuners and he changed to plugs and put 110 octane gas in it and right now there is no issues at 12lbs. But being a street car can't keep putting in 110 octane in it.. He wants to keep trying things at my expense.. But coming here to the best place to find anything out

Get a meth injection kit.

I was just looking at that a little bit ago..

So change the heads to a 71cc heads from 62cc and put a meth kit on it. I would like to be around 700-750 hp at the rear tires
