Submariner is very close as it was around $12,000 when all said and done. |

yea
and that would be great
if you could find someone who has hacked the OBD2 fwd N* to adjust timing/fuel ratios... |

AJ...If I get it installed with no changes to the OBD2...Will it still work but not to it full potential? or Changes have to be made?
What has to be done for some of us that are interested to get done?   |

OBD2 is not the computer, it simply refers to the standard for the On-Board Diagnositc (generation 2) system for automobiles... Quote:

A 99 STS will need a complete engine rebuild and head stud kit for starters. Also rebuild the transmission and use DEXRON-VI fluid. THEN you can start to work up the turbo install, that alone about $6000 - 8000 in specialized parts, brackets, piping, labor. By the time you get the PCM maps modified enough to run the thing, you'll be into the car for a little over $14,000. One of the bugaboos is the precious little room to work with, either front, engine, under, or rear.
Remember the "Gosh, gee whiz, wow, awesome" DTS that was converted to RWD with a 472 engine last year ????? It must be a really great, reliable car to drive because it's for sale, again. |

IDK about the rest of the years tho.
Also sub, why would you say to use DEXRON-VI fluid for the transmission after the rebuild. Is it better than what was in it before.
My 96 uses dex-3 I believe, Is there a benefit to use dex-6?
Also is it true you can use anything that is dexron-3 and up in my transmission or is that wrong?

At this point I'd say that the differences between DEXRON-VI and -III are in the eye of the beholder. There's a LOT of -III on the store shelves, but -VI is the up and coming thing.
The reason I suggested -VI is that, with a new transmission, it's the time to go with a newer heavy duty fluid.
Just as with dino or synthetic-altered lube oils, it's your call. |

If I new anything about how an internal combustion engine works, not forgetting for a moment forced induction, I wouldn't be asking the question...  I believe that is why we are here... to ask, find out, and learn from others knowledge, experiences, and mistakes. 
Difference between N* vs LS1 Camaro ?.....Two Guys Garage did the install in a Camaro with no complete engine rebuild nor head stud kit. STS advertises that it can be installed on any car....Are N* not built tuff enough to support a turbo if possible? (probably another pretty funny question with a guaranty for us to learn something) |

STS sells generic turbo kits. What's in the box is only the smallest tip of the iceberg.
In regard to your question ".......N* not built tuff enough......" No, they're not. To adapt a N* to forced induction the first thing would be to pull the heads and use Jakes head studs to make pretty sure the gaskets won't blow. N*'s use somewhere around 10:1 compression, so that should come down a point or more. Then you have to get with AJ and work out a new fuel map. Then you pray, and don't expect the car to be a daily driver. |
