If you are 2WD already I'd use your existing diff if it's in good condition.
Barra now does a front diff that is his take on the old R&D item.
As for sequential boxes a Quaife 6 speed one will be something like £10/11K plus VAT

That's what this car has with 500bhp.
If you go for 800bhp you'd need to talk to somebody like Rod, but I suspect you are into 9" motorsport diffs etc
You must be kidding if he has torque no 7.5 inch diff will last. A friend of mine broke 3 standard diffs then fitted a quaife that just lead to breaking the c.w.p.
He now runs a supra diff that has given no issues other that teething problems with the mount to the floor but that now seems to be fine. I had a gripper in mine but again stripped the teeth off the c.w.p supra now but obviously not tested yet as mines in bits. Ford 9inch is serious money but again rod has another option that seems un breakable with the Daimler option he has
