Rb30 In R32 Gts

[LedZepLen]

i have a r32 gts with a rb20. I'm running a top mount exhaust manifold, synapse 40mm gate, to4e .60 ar .63 exhauast. gtr injectors, z32maf, front facing intake, 4.5" thick intercooler, meth injection, mines ecu with a e manage untimate with a map sensor.

Could i do an rb30 swap with 25 or 26 heads using my stock wiring, ecu and e manage ultimate. and run 550 or 660 injectors and tune it right. The rb20's nice but the extra tourque would be nicer. My p[lan would be to swap out my engine for a larger one but retain all my boltons with slight modifications and maybe a bigger or twined tuboes. If i kept it all would it run without a tune? Would i beable to max out the turbo? I'm saving for an r34 so i dont wanna waste my money doing a 10k build.

What do you rb geniuses think? If u were cheap and wanted fast drag times what would you do without cuttind down my bolt on list to much and without a $1400 ecu
