i paid R1700 for the piping kit. And the kit fits the Sr engines perfect.
I put it on my CA but the cold pipe needs some Custom piping so i am busy sorting it out.
I also had to remove and relocate my battery to the trunk but that is pretty easy.
So i think if you want to dont put too big intercooler as i have seen that the standard one that came out is pretty small. But then again it is your choice.
If you can go visit ebay and look for one it should not cost you more than R4000-R5000 for the complete kit but it depends on Shipping and what size intercooler you take.
o my intercooler size is 600x300x76 so it is pretty big upgrade for my CA.
Happy searching man.
