I'm currently running the SRP pistons in my B16 which I believe 10.4:1 compression (their off the shelf pistons). I would like to raise compression and was told the CTRs are good for about 11:1 with the B16 head. Can anyone tell me if this is a good upgrade?

 

yeah it is a good upgrade but you will have to have your cylinders bored to fit those ctr pistons....

 

Yo9u mean CTR pistons don't come in 81mm?

 

you can get standard size cr pistons, run the srp's because they are a forged piston, and they will be good for some nitrous, later.

 

Do you think I can run a JR supercharger with this compression?

 

i would run a supercharger with as high as 12:1, but i like to push things to the limit to.I think with some injectors a regulator and pump, with hondata or some type of management, you would be fine.Superchargers like compression, so try and keep it around 11:1 to or so, and run the srp's.

 

With the compression you have now, you will be fine.

 

Thanks alot for the help!

 

srp forged

 

Thanks alot for the help!

 

i would never switch out forged pistons for stock cast pistons....going from 10.4 to 11:1 is hardly any diffrence......leave them alone!
