Ohhh ... this ought to be fun to watch ... get video of with the hood up when you start the car with the turbo on for the first time

3.0L block + 2.5L heads = CR ~11.2:1 = Not very boost friendly

The Aspect Ratio of the turbine housing is reportedly a T4 1.34. That is enormous. I don't think a 3.0 will get it up to full spool.

If you don't know what A/R is and how it relates to making power with a turbo, don't even think about trying to turbo your own car ... unless like I said, be sure to video tape the first time you try and run it ... with the hood open.

Considering the CR of the engine, I would suggest Nitrous ... all the kids are doing it

You could save some money and buy my Turbo kit on ebay in two weeks ! Taking the whole kit off on Thursday. Complete setup. ( Big 16G turbo; all piping; RFL BOV; AZ Chip; SAFC; 30lbs injectors) Starting at $1700 on ebay, or build it yourself for about $2500-$3000. Have fun and good luck. -B.
