I searched around but couldnt find a good answer. I've heard a lot about the ford 8.8. But I'm not sure if it bolts right. Looking for more info. I will be doing a 20b swap and am trying to build a drivetrain that can hold up to about 700 rwhp. Any thoughts and info would be greatly appreciated. Thank you

 

whoops i think i spelt recommend incorrectly... <--that doesnt look right either.... anyway anyone wanna schimme some words in?

 

cobra diff

 

Will the cobra diff bolt up to the fd chassis And what axles would be used with this diff

 

there is a subframe for it but i have not done one myself.

 

there is a thread somewhere and one guy built an ls1 fd and he made a cobra irs fit in the fd subframe! very detailed. google search "most detailed ls1 fd build" should come up! its a blue fd

 

Short answer: for that kind of HP you don't just change the diff. You need to upgrade the whole drivetrain.

The Cobra IRS is one of the better options. I suggest spending some time in the 20B and other engine (V8) forums to see what those setups are running.
