I want to build a d15b2 and go all motor, right now I have just about all the bolt on u can have including p&p TB P&P intake, mpi conversion SI cam, aem cam gear ETC.. what would be the best head to put on to get a few more ponies. eventually I plan on new pistons to raise the comp.right now its 9.1.1 good for an HMT thanx

 

well a d16y8 would raise your comp. to about 10.2 that would be nice or if thats a little to high for ya you can go with a z6 that will bump you up to about a 9.8 witch is fairly turbo friendly for any future turbo plans

 

go y8 with high CR pistons and you'll then realize why all-motor honda's are slow and you'll convert to boost.
