Basically i would like to do this to mine. would like to know what mods are required, as im in the research process, etc.
pm me if you like.
A few opinions would be good.
Free flowing exhaust/decat (shameless plug here I have exh/decat for sale)
Air filters
ideally 550cc inj but Middlehursts 500 conversion uses std 444cc ones
Steel internalled std turbos running 1.2 bar wont quite do 500hp IIRC
Step 1 drop in cams
chip/remap/power fc/boost controller
Recommended
steel headgasket
oil cooler
uprated clutch
I can recommend RB Motorsport as Rods engines last unlike some "specialists" who are no more than enthusiasts claiming to be experts.
