XJR6 Upgrades

[bigdavy]

Hi folks, I'm on the brink of buying a mint XJR6 1996 model and am considering a few upgrades. I would like to ask if anyone on here has done any upgrades to their XJR6?
I'm thinking of things like the supercharger upgrades, possibly ECU and exhaust?

What about the brakes? Any comments on improvements?

Any comments / advice greatly welcomed.

Thanks, Davy.
