Hey had recent bad lick valve dropped figured I'm gonna go crazy and build my f20c for a turbo wanted to start out by resleeveing it and saw that darton has mid wet sleeves now and was wondering on input if it's waste of money and I should go with normal non stock ones or spend the extra 400 about on the ones that are supposed to be better any input would be great

 

I have them 3.5 years now on my block without any problem. Fitment is a bit complicated though so you have to find someone who knows what he is doing

Ok good deal thanks Chris and I'm guessing u have the regular steel ones? Cause I was on real street website and they have a the wet mid sleeves and was wondering if I'd be over doing it buying those lol

 

The MID's will give you a closed deck and much stronger cylinders, maybe overkill but feels like a better solution. The cylinders are thick and standing in water, this will help them stay round even at crazy cylinder pressures.

The dry sleeves can suffer from heat spots caused by air or water between sleeve and block. This will make small bumps in the cylinder wall and cause piston damage. Also, the heat transfer between the sleeve and alumninum suck and that´s why OEM engines have sleeves shaped like spikes on the outside and casted into the block. Saw this first hand on a few rallycross engines, they use MID´s now.
