I assume it is already a 4693t?
I've done some google work and it looks to me that there are some options for you, however you can't use a 63 manifold on a 93. An easy way to check if it will fit (once again assuming it is already a turbo engine) is to go to repco and ask about the turbo gaskets, if they are the same then that solves the fitment side of things, I honestly don't know if water/oil lines are the same, but some one else who is on this forum will.
If it is not turboed then.....
- bigger injectors
- remap fuel system (unichip, safc, etc.)
- intercooler
- turbo
- cooler pipes
- tapped oil sump
- decomp plate
- oil and water lines teed off the pressure sender
- turbo exhaust manifold and modified exhaust pipe
- fuel pump and pressure regulator depending on boost levels.
- modplate or engineering.
forged internals if you wanting to run decent psi and not pussy footing
Hope this helps.
