Good greeting to all of you,

I'm surprised and disappointed when I just opened my ej20 engine and found it with open deck.

Need your advice if I have to switch it to closed one or go on to build it up with upgraded pistons and rods.

My target is 400 WHP max.

A friend of mine was running 10.7 et on open deck ej20 with WM injection. I would think it makes 400whp to be that fast...

There are inserts and other methods to stabilise the tops of the cylinders. If you're worried, you could check those out?
