Calling out to JE pistons specialists :-)
Hello, I need to buy a new piston set (my engine has seriously detonated because of wrong ignition map).
My engine is a 3.3l 930 heavily modified - however I was using the OEM P&Cs from Mahle. The cylinders have been checked and are like new (they have 5k Miles...) I am considering the pistons from JE. It seems like a good option would be the set ref 331158 in 97 bore and 8:1 CR (I will not be using crazy amount of boost, keeping it at .8b, and using EFI) However, I also saw on their website that they have another reference in 97mm bore with seemingly same CR : the 353302 - it seems to have thinner wall and few other tricks. Before I reach out to JE, I wanted to know if someone was familiar with their range of products and can explain to me the differences ? Thanks a lot Mathieu |
