Iam currently using green 803s on stage 3 chip but only a t3 turbo iam in the process of getting a t34 and have seen some greys advertised. My question is could I use greys, would it be better or no good?

what exhaust housing has the t34 got? depends on what power you want,i personally would not get the grey injectors

Siemens 55,s is often advised with that turbo depending on spec and power wanted etc. From what you pick up on here greens are perfect for T3. The T34 can need more fuel.

As said siemens are a better way to go if your changing turbo chip etc imo too

If your on about my greys, I prob have some kind of deal with your 803 and chip, i was going to use them with t34, if you have the money then siemans are the way, but loads still use greys, mates had greys in his for over 8 years, engine still going well, tho he does drive like a old fart.
