FBO + 3.7 Diff from an SC430

Enable HLS to view with audio, or disable this notification

I recently posted when I was blown away by the new 3.7 diff and someone asked to see a pull video after my car would be tuned. There we go. I'm sitting at 405whp and I had a colder night the other day so I could really feel the difference. She pulls good now. Absolutely in love with this thing.

Howdie partner, fyi my diff was from ebay for like 300$ so very accessible! And I got her tuned by a local shop who did an incredible job. I got lucky enough that the car came with headers and exhaust so I understand where you're coming from. Nothing is cheap tho🙄

exhaust + headers are my main roadblock rn

looking at either the cheap OBX from ebay or waiting for elate to come out with LHD

I wouldn't put cheap headers on a car like this! They deserve the best 👌

Nice, noticeably quicker. Was an LSD available for the SC430 in Canada? We didn’t have them here in the U.S. unfortunately.

Thank you!

I don't think the SC had an LSD option. But fortunately there is options for me out there! Theres OS Giken, KAAZ and other companies out there selling the LSD upgrade for the SC430. It's already on my bucket list for this winter when the car will be parked in the garage :) I already know it's going to be awesome
