Anyone have a rough idea of what size fuel injectors youd need for turbo'ing the KA, or type of fuel pumps?

I was also wondering if anyone knew of any places that make and/or sell turbo exaust manifolds for the KA too?  Any help would be greatly appreciated.  I already know the whole war between the KA and SR so no need to fill me in

Thanks

i believe you can safely run 7psi on the stock injectors as long as you have an adequate fuel pump and fuel management.

can get a turbo manifold and all your other turbo needs for your ka24de(that is assuming you have a KA24DE not a KA24E)

You can use the stock 270cc/min injectors with rising rate fuel pressure regulator and a high pressure pump.  Walbro pumps are the cheapest, and work very well, better then the z32. Go to the FAQ and look at the things people wrote on the turbo kits in there.  
If you want to use the stock fuel pressure regulator then you can just get the pump and 370 cc/min injectors from a sr20, heavythrottle.com has them.
if you want the revhard manifold, then get that from them or search for somebody cheaper on Google.  Otherwise, the options are thin for other manis
