Rebuilding the motor, daily driver pulling once built suggested pistons or keep the stockers??

 

I would keep them if theres nothing wrong with them if u want to get fancy they make all kinds of expensive ones

 

I will have to get new ones either way; just which ones

 

2nd gen pistons and P pump it. The bowls make good use of a 155° injector.

 

3911400 piston is a good one.

you can also go with the lower compression piston as well, cant remeber the number for all of them.


make sure you get premium rings.

you can go here

it shows stock pistons and then the 3911400 piston.

 

What advantage do you get with them?

 

it is doing the correct way of what everone is putting a 0.020 oversized gasket on.

it will allow more air to be forced in,(really helps in larger turbos or compound set ups) if you go really low, your engine will have a hard time to start in cold weather.
