I am goin to be doing the 20b swap after deployment and am trying to get to build a strong drivetrain. I here he ford 8.8 is a great diff. It doesn't bolt straight up though does ind I believe I heard that I may need shorter axles... I'm not sure about that one though. Please help

 

You didn't state it, so did you read the faq? provide more info on what you think you know so we can tell you if it needs some clarification to help you out

 

Sorry yes I read the FAQ.. I accidentally made 2 threads on this as well and on the other thread someone pointed out the 8.8 cobra irs. Someone has an in depth build while installing the cobra IRS and there appears to be a crap ton of welding and custom fabrication... My he goal is 700 rwhp but I won't be running that much all the time. I will be running around 5. This is just a weekend car I'm looking to have fun with and build right. Probably go to the strip a few times a year.

 

"...700 rwhp but I won't be running that much all the time." <- What does that mean? If your car has been dyno tuned for XXX amount of RWHP, you car is a XXX RWHP car all of the time. (As long as no MAPs or other modifications have been fucked with.)

If you're asking questions about differentials, it makes me believe you've already done PLENTY of research, and have sourced your 20B engine (long or short block), turbo, a fabricator, etc... The fac that you're even asking about differentials, makes me believe that you ma not be prepaired to take ths on. I only say this to save you money. Even a 500 RWHP 20B is going to require an insane amount of money, attention, fabrication, and ESPECIALLY knowledge. You should really contact a lot of the huge HP 20B builders for resources.

Have you considered a 13B-RE? A high HP 20B build is beyond a lot of people's knowledge... I am not doubting you or saying that you cannot do it. I just KNOW that cutting even a measly two corners in a project of this magnitude, would blow your bank.

 

easy, high and low boost switch.

 

^that. This is why I am asking. I have read the faq I am just taking in info right now. I have a shell and I am looking to build up and I am def one to be unique. I have met a guy in town who works on them out of his garage and has lots of knowledge but I don't know him that well. So I thought I would ask my questions here and take notes.
