Mines 9:5:1 and i got diamond forged pistons
thats stock compression right?

Just wondering because i dont see or hear anyone talking about it everyone says that have 10:0:1 or 10:5:1

whats better higher or lower compression?

 

stock is 9.5:1, there are higher compression pistons available...Not sure which is better, higher or lower, depends on how much boost you want to push and the extent of cooling mods. Really just depends on how far you are willing to push the motor, but to give you some kind of answer, lower compression is safest for high boost on pump gas. If it were me I'd go with the 9.5:1

 

8.5:1

 

????

8.5:1 isnt necessary unless you are running stupid boost levels

 

I believe that's his point?

 

Google the word... MP5T

 

theres the answer
