Hey every one I am currently building a b16a2 head and a gsr block.
My goals are to reach 220-240whp and maybe more.
I have currently Hondata S200 and in process the b16 head/ gsr block being built for my all motor project.

I am using Jun stage 3 cams
ferrea valves
ITR retainers or Ti retainers but not decided
port flow dual valve springs.

and for the block is where my question comes in.

The block is going to be fully built with sleeves and bored to 84mm.
I am curious as to what compression piston heads i should use to help me easily Make 220+whp, thats i want? I know pump gas will be out of the question but thats ok cause its going in a track car for NASA and ASRA events. I was looking at Wiseco 11:3:1 , 2cc dome pistons but from a few dyno's and im missing some of the most important details such as how they made 220whp using hondata and those pistons. Not sure what cams they used but they made 220whp on Wiseco pistons.

So should i go with lets say a Wiseco- 84 mm 11.3:1, 2 cc or IB Spec Probe 84 mm 3.5 cc, 12:1 ? Suggest any others?

Also if im correct if i use a LS crank in a gsr block the throw of the stroke of the piston head will be longer there for producing more torque and with the help of the new 84mm bore instead of a 81mm. Dont quote me on this but i thought thats possible. Should i just stay with the GSR crank? The motor will be built for 10K redlines but i dont plan on taking it up there every time i shift. I would like to make power to 9K and with the JUN3 cams i think this will be easy to do.

Thanks, much for reading. Ill listen for your input.

Using the LS crank (and rods) will help you pick up a little more power than the GSR crank. Look at pistons that will give you at least 12:1 compression. You are going to need head work, a good header with at least a 2 1/2" collector, exhaust, intake manifold, larger than 62mm throttle body,a good intake, bigger injectors, and a good tuner.

 

Take a look at the Arias web site there may be something you could use.


Or you could pm Me if you have questions.

Get high compression pistons im running 14.5:1 on race gas......

 

Im looking to go with 12:5 or maybe lil higher compression. I do plan on milling the head and port polish with a port polished / milled matched intake manifold such as skunk2.

 

Tom's been very helpful everytime i bug him about pistons. Thanks tom (call me soon, ready for some pistons)

oh god 220-240 for daily driviability man...not on race gas and 14,5:1
