Looking good, I have been driving my swap for over a month now and I love it!!
Still bone stock motor except for custom headers and intake, and I am also wanting more power, first off I have the 3.15 gears like you and I am wanting to step up to the 3.73, and I need to use a different carrier I am told since the carrier for the 3.15 ONLY fits the 3.15, but I am still no totally sure on this..
I am thinking of going with an 8.8 swap that already has the 3.73, LSD and disk brakes to begin with, would be cheaper...as long as the width is the same on the X-runner as it is in my 1st gen..
What is your next plan for power? I am in the same boat and I have no space for turbo, I was thinking a twin screw if I can find one for less that 3K, or maybe a 408 H/C upgrade, it all comes down to what I can afford and find for a good price, I need more power!!!
