Swap block out for a second hand good cond 33 gtst det block - your choice to rebuild here if you want. (u may even be able to reuse ur old block if its got oil squirters for the pistons. If so just whack in det piston and rods, new bearings and headgasket and ur set.)
You will need the complete det turbo and intake setup - turbo plus oil and water lines, exh manifold, dump n front pipes, intake pipe, air filter or airbox, fmic interooler kit, manaul bleed valve.
Whack in a 33 gtst ecu or go pfc (again your option depends on budget)
The difference in the de cams will give you abit of gains compared to det cams.
Since youve got 50% more power, ur gonna need tp address.brakes so gtst brake setup and 5 stud conversion os on the cards.
You will also need to put the power down so a gtst viscous lsd will be needed.
Unless ur car was purchased fpr dirt cheap like 4k then itll be worth it to do the above, otherwise just sell and get an.original gtst as they are cheap these days.
