I personally have a ko3s, 3"downpipe with 2.5" custom system, FMIC, TIP done, dump valve, relocated filter down into the wing, CC stage 2 by badger 5.
Im going to be buying one of the INA turbo Manifolds also.
Firstly what kind of power would my car be running on those mods?
would it be cheaper for me to go down the hybrid KO3s route or start to buy all the KO4 parts? bearing in mind ill need EVERYTHING involved in doing the KO4 conversion?
