550 cc for Z20leh

[bogdan.panainte]

hi!

Does anyone know if I can use injectors 550 cc from EDS on Z20LEH without modifying the software?
I have to go with them from Romania to Germany about 2000 km - and i do not know what should i to do because i did not get in touch with mr. Arno Schindler.
Thanks,
Bogdan

not possible, you must modified the software !

You can use the 550cc injectors in the case of you reduce the fuel pressure with an adjustable fuel pressure regulator.

oder andersrum, dann kann er sich die düsen sparen

i do not understand german

i use a adjustable fuel pressure regulator (2-10 bar) from nesso racing with the orginal injectors

He commented that you could simply increase the fuel pressure instead of using bigger injectors. The 470cc injectors are good for more than 400hp.

Arno advise me to use the bigger injectors, so the fuel pressure would not be so big.
another question: should i change the milltek exhaust that i have now (63mm) to 76 mm to achieve min 400 hp (i am running a GT30R-WG with forged internals, EDS inlet cam, larger intercooler, ceramic clutch, etc)
I am looking for the inlet manifold from EDS - do you think it is needed for min 400 hp?

i think you need for more than 400ps the eds manifold! Max with serie manifold, around 380PS-400PS!

Maybe more than 400PS, but with much more pressure!
