I'm finally going Ls/Vtec on my CRX and want to stay all-motor. What would be the highest compression pistons I could buy for a daily driver on 93 pump gas...11:1, 11.5:1, 12:1, 12.5:1?

What about a daily driver with a shot of nitrous on the weekends?

What about a daily driver with a JRSC at stock pressure (8 lbs)?

What about a daily driver with a JRSC and a shot of nitrous on the weekends?

Any piston brand name in particular you would recommend?

Thanks!

 

12:1 is safe 12:5 is questionable

For pistons... if you want to save some money... use b16 pistons and ls rods... get the rods shotpeened and use ARP rod bolts and you will be fine... if you use a gsr head and mill it about .010 and deck the block your compression will be around 12:1

 

13:1 is safe if you have a good tuner
