How is it that a vette is brought up in a 4x4 forum?
Two totally different animals.
hmmm... stroked small block, dry sump in a sports car vs. v6 4 cam that has not been factory prepped for race and lugs an additional 1200 lbs around.
First, if you have 70G +/- 5G to dump on a new Z06 you wouldn't be debating over a blower for the X.
Most vettes are 465 to the rear in bone stock form so yes, grabbing 75 rwhp in N/A mods is fantastic, but that can easily be had on any v8 with bolt on mods, especially an early 80 choked-down sb.
If someone manufactured true long-tubes for the x and a real exhaust that complimented the blower you would see more than 90 rwhp. Unfortunately, no matter what you dump into it, it is still a family wagon no matter how fast you make it.
If I wanted an insane 4x4 with corvette 0-60 times I would build a 408 powered early Bronco that tips in at 3200 lbs with a top and 3000 without. Then you can buy door inserts and remove the tail gait for another quick reduction of 200 lbs, but then again who cares, this is an Xterra forum and not an early Bronco, Zed, or what has a better hp/dollar performance ratio than the X forum.
The new Zed is a fantastic car, but comparing gains to an X is a bit far fetched.
No offense but lets keep this on topic so the thread doesn't get locked.
