Hey guys, I've been contemplating turbo charging my 331 for a while. No, its not a dart block and, yes, I know its only good for 500hp under 6k rpm. The question I have is does anyone have hands on experience with on3. I plan on running less than 6psi making no more than the block can hold. I do have a balanced assembly and a block girdle installed. ( just to keep the crank together when and if it cracks ). They have a fuel system kit for about $1000 w/dual 340lph pumps. With the upgrade to ceramic ball bearing turbo, 60lb injectors, and MAF ran the total to about $2500 w/o fuel system. Is there anyone here that can offer advise on this set up ? I've already dumped over 6 grand in a 302 block (stupid) HCI stroker kit, at least its a Mexican block. smh
