How high of compression run on the street with no problems running on 93. what pistons should I use as well? I've heard that 11:1 is about as high as you can go on pump gas is that true or can I go higher without adjusting my timing to much.

11:1 is a great street number. You can go as high as 12.5:1 with cool weather and capable tuning. SOme peopel even do 13.0:1

 

So I can go 12.5:1 and be safe on the street with no problems.

J.E. pistons are good but what about C.P.?

 

i think will compression above 12:1 you need to take into consideration piston to valve clearance, so maybe clay your motor, also if you are gonna go above 12:1 and try to use pump gas you should probably get hondata, or something like it to tune properly so theres no predetonation problems.
