Injectors & FPRs

Post by Stu13R »

I know their are very varied views on this subject but I wanted to see what owners thought of changing injectors?

Having done a bit of research I found the current injectors in the KO4 R models can be used up to 500hp and are the correct spray pattern for the head set up. I see on the FSI engines some owners have gone for RS4 injectors and various others form VW/Audi variants. If the spray pattern is good for this engine and can go 500hp what is the reason some owners swap for RS4 ones?

Regarding FPRs what is better on the OEM front i.e. RS4 or TTRS, or are there any aftermarket units that are better?

I am looking to go over 400hp with either a Hybrid KO4 or a completely different larger turbo like Loba or APR, therefore need to plan the rest of the fuelling hardware. I imagine an RS4 LPFP and probably the Loba HPFP.

Has anyone got feedback on the RS4 injectors?

I have been told some owners are having a few issues with the RS4 LPFPs so I want to get this right, or even do some research on what better alternative there is available. I'm surprised Loba don't do a LPFP or injectors.
