Going to upgrade to a bigger turbo in my 03 ho , When I upgrade to a 05 I want to be able to swap most performance mods over.
Otherwise I will have to change plans.

Also what turbo seems to work best with the 03,s at hopefully about 450 rear wheel hp +/-

Thanks.

 

Different turbo on the 04.5, it has an electronic wastegate controller.
Also a larger compressor wheel and compressor housing.
Sort of like a hybrid 40.

i believe there is also 2 other sensors in the compressor housing on the new 04.5 engines... a turbo speed sensor and a temp sensor...


here is a cut away pic of it
