How durable is the stock Ford (2V) 4.6 liter Modular V8 found in 1992 to 2011 TC, CV, MGMs? Could someone install a 150HP Nitrous kit without burning the pistons or adding a supercharger without blowing head gaskets? My question is based on a low milelage engine in good shape. |

Unmolested, the stock 4.6 can handle a few hundred thousand miles.
A stock engine could handle a few pounds of boost for quite some time.
As logic would dictate, up the boost and you'll need to build the engine to handle it.
The Performance Improved engines('01+) would be better and there were a few years with bad timing chains/guides so low miles wouldn't be great, you would still have to check those out or replace them anyway. |

Go to www.crownvic.net and see what people have done to their cars. Once you start adding about 50% more horsepower than what the engine originally had, you go onto borrowed time. Sean Hyland http://www.seanhylandmotorsport.com/ got a stock motor up into the 400 HP range, but then he knew what he was doing.
IMHO, a 75HP shot of nitrous, a small turbo built for a four-banger, or a blower set at the lowest boost will help these engines. But if you want some POWER, plan on replacing the internals with forged. Check out the Mustang forums and you will find people who have hit the 1200 HP mark with forged internals. You may be able to double the stock horsepower on a stock engine, but when it will blow is anyone's guess.

I thought the 2V 4.6 V8s came with forged/roller internals? |
