Can someone point me in the direction of:

a) twin turbo kits for 99-04 mustang GT's (besides hellion or peregrine performance),
b) links to well-documented homebrew TT builds for 99-04 GT's, or
c) Some general information of what works and what doesn't for homebrew TT setups?

I know on 99-04 V6's, you can flip the stock headers and with a cut and weld to clear the motor mount on the passenger(?) side you can use them as a start for your own turbo manifolds. It appears the peregine performance kit uses some form of flipped longtube headers that have been adapted for twin turbo use. Kinda looking for something similar on GT's to satifsy (c) above.
