i know there is places that can do it cheaper but people have been making good numbers with BNRs reliably. i got mine for near half the price and it worked out ok but i have no freaking clue who built it so it was a gamble but i won.

4 720's probably would do just fine, it really depends on the trim of the turbo and how high of boost you plan on running. i'm not a turbo guru but 720's all around should handle most hybrid setups with a standalone.

Your injector choice should be dependent on the amount of boost/amount of HP you intend to make. Its a decision not based solely on the turbo you select.

well my buddy has the rtec 1.7 stage 2 bnr walboro rewired 550/720s fmic and a safc to set the tps at 1.0 not used for fuel the rtec takes care of that and he runs 12.1s with nitto 555 very cheap set up but works well without a standalone and he beats the snot out of 7 he just cant blow that engine because he has a streat ported engine to put in but this one keeps on chugging

I run a BNR 60-1 with 4 720's and a S-AFC (ran off boost sensor instead of TPS). You dont Need a stand alone. 720's are actually plenty of fuel I barely have them at like + 10 or so in boost and have 10.5 AF.

However if you do any tuning you MUST have a wideband O2 setup or you are simply tuning blind.
