Bottom end will have to be wet sleeved, looking at general options. Aiming for somewhere in a general range of a 400-500HP car, not explicitly a daily driver but still able to be daily driven and be a weekend toy. Worth it to take the extra cost and build the engine (wet sleeve, rods, pistons, etc.), or just get a new bottom end, refresh it, and go with it?

 

I would just get a new stock short block for that power and a different tuner.

 

Why would it "need" wet sleeves? Did you crack one? I wouldnt reuse a block that cracked a sleeve

That would be why I need one, sadly.

 

Did the other cylinders melt like that?

If not i'd tend to point to a bad injector. Make damn sure you get those things sent off and tested before they got back in another motor.

A very bad tune will usually cause similar damage in all 4 cylinders.

 

No, only that cylinder. Leaning towards a bad seal, but they will be flow tested, depending in what I do. So damn expensive to get another f20c.

 

Holy shit that's ugly
