Hey guys tryed searching this but didnt find much.
any help is good
I have a BRN32 skyline gtst, It had a rb20det in it and i took it out and swapped it with a rb25det, the only mods the rb25 has is a greddy intake manifold.
Im thinking a bigger fuel pump, gtr or maybe a/m, and possibly bigger injectors too. im using the rb20 ECU with the rb20 loom.
My question is what is the best tuning method, buying a new tuned ECU, getting a piggyback? AEM fuel to air ratio gauge. any other upgrades that would help?
Anythin info will help i just want this engine running good
thanks!
