Put it this way, i have about 15k into my entire build. Thats motor, 6 speed swap, and everything included. Im pretty sure the 6 speed will reliably get me in to the mid 9's without a problem at 160+mph. Its a strong trans. Much stonger than the GTIR trans thats for sure. The cost of the trans swap was about 2500 for me. So yeah, well worth it and not a single problem.
