learned so much and had so much fun

Wow. Amazing. That is one mean ride.

Thank you! I spent a long time looking through pages of other members rides and after seeing so many cool rides I decided to post pics of mine. Everyone on this forum is great. So many interesting and awesome projects.

i can see why you blew up the oem diff. i dont think the open one is going to be much help though. i have a auburn limited slip that has stood up to some abuse, but my car is pretty light. you may want to get one of the mechanical types

Yes, I agree for sure. I will be keeping an eye out. I am also currently working on my police interceptor daily driver so money is tight right now but down the road I can see a 4l80e or fully built trans in addition to the rear end

the 10 bolt might be fine for a while with 3.42 gears and a open rear. i have a ten bolt but its got the main cap support, better axles, and 4.10 gears and the eaton limited slip. ive got a whole bunch of strip launches on it. a bunch of people run ten bolts, and turbos are a bit easier on drivetrain stuff too

Looks amazing! I saw you video on another post and showed it to my friend and he says, "And that'* an ENVOY??" Hahaha

haha thanks for the compliment. It is funny to see/hear peoples responses to it. some love it some hate it and some are just not sure about it lol.

i think its cool, i think that if you got into the tuning of it you could 20-22 mpg hwy and still be fast when on it or at the track
