Hey! First post on here so I'm hoping you all will know more than me. I have an 06 4.0L v6 auto (first car, don't judge me, it was what I could afford at the time) that I'm now swapping the 4.6L v8, TR3650 manual, driveshaft, and rear end from an 06 GT into. I am upgrading things as I go but the end goal is 1000HP. I have a set of mirrored Nelson Racing 88mm turbos and the plan was to go meth injected and hopefully make 1k with that. But I now need to start looking at upgrading other parts like my transmission. Since this is a track car only I don't care about trans whine or comfortability, just bulletproof-ness. I'm hoping someone on here knows somewhere I can get Straight Cut gears for the stock TR3650. I've done 4 other builds in the past but they were all JDM builds. This is my first foray into American Muscle so any and all tips or advice about building high horsepower V8s is welcome.
