Convert easy?
how? By buying an entire SVT engine, injection system, MAF, TB, PCM, etc and installing it.
I think you need to research the differences between the two some before you fly off the handle without a clue...
Here are just some of the differences between an SVT and a non-SVT.
More Aggressive, Longer Duration cams
Extrude honed intakes (upper & lower ~ 99-00 had more done for +5HP & larger LIM)
4mm larger secondary throttles which also open 400rpm sooner
Extrude honed heads (both primary & secondary intake ports - 98 only had Primary?s done)
Different pistons (10:1 vs 9.7:1) (00 - 10.25:1)
19# Injectors (vs 16#)
60mm throttle body (vs 54mm)
More aggressive PCM
Conical filter assembly
Lighter flywheel
Water to Oil Oil cooler
Larger radiator
Beefier motor mounts and Stab-o-shock Engine roll reducer
That's just some engine & associated eqpt changes alone.
Not including appearance items, rims, tires, struts, springs, sway bars, brakes, etc...
Plus some people like the fact only 11,445 of them were made.
