So i'm planning a 1.9 TD swap on my sammy this winter, while i have it apart im going to do Toyota Axels. From what i can gather online, you do not have to upgrade the drivetrain unless you go TDI. However i am planning on putting in a Giles Pump and new injectors to try and get HP closer to 120. Im wondering if i should upgrade the drivetrain to handle this new power, or if its unnecessary. I'm pretty new to the subject so any info would be super helpful, or if you have anything you think i should read i would greatly appreciate it! Also, im not worried about gas mileage, ultimate goal is a decently capable crawler that can go 70-80 on highway without screaming.
