I have a 1996 mustang gt 4.6 2v
I'm looking for a wet sleve kit or somewhere that can do it in Texas. It has about 200,000 miles for or take(dash reads 135,000 but is stuck) I haven't taken apart the engine yet but it has low oil pressure so I think that the main bearings are pretty worn

 

I don't know what a wet sleeve kit is Please explane it to me?

Unless your looking to stroke it to 298ci, you shouldnt sleeve. There are no advantages to do it. Just get a simple rebuild kit and do that. Unless you have damage that you cant fix by boring the cylinder, which if you just have low oil pressure and no knocks or anything you probably havent, then dont get it.

 

Actually.... One of the advantages the current 5.0 and 5.8 have over the older 4.6 and 5.4 mod motors are larger bores resulting in better airflow due to unshrouding the valves.

Darton is a one of the leading wet sleeve manufacturers and they produce big bore sleeves up to about 3-3/4 (95mm)

However, by the time you get the sleeves and install them its cheaper to go with a 5.0 block unless your going to do something like a sleeved 5.4 which would yield on the order of 366 or so cublic inches.

Waiting for the 5.8 block in the current GT500 to make its debut might be a worthwhile option as well depending on the price compared to a sleeved 4.6 block.

In any event increasing bore diameter rather than stroking the engine will produce better overall results provided you can achieve a similar and meaningful increase in displacement.
