QUESTION: what pistons should I use???? I know i'm gonna be buying
j.e. pistons but 11:1 compresion or should it be 13:1 due to the head milling?
but i also know that 11:1 is for street use and it's okay to use 91 pump gas,but 13:1 is for race gas. U.S. has 91 octane gas and I heard that is not good for the motor.

I don't want the motor detonating on me. Plz help out,

email me at: dragonz04@hotmail.com

 

if you're hardcore you'll go for the 13:1's but if you want it to be streetable and cheaper on gas go with the 11:1's it'll still rip ***!!!

 

I will go for the 13:1, but what kind of gas should i be pumpin?
and should i get those "octane booster" ****, does that actually work?

thanx

 

If you go 13:1 you won't be able to run it on the street with pump gas. 12.5:1 is about the highest that you can go safely on pump gas. The higher the compression ratio that you go the more heat that you will be grenerating, and you don't want to cause detination were your burning a hole in the piston. That would ruin your day.

 

Thanx a lot, so I should go w/ the 12:5:1
what else should I do, to prevent engine detonation?
