bnr stage 4...
So I am relatively new to the rotary world but I ran into a guy that wants to sell me a used bnr stage 4 turbo and an rtek 2.1 ecu the car right now is stock other than a fcd custom intake and a full rb exhaust he said with that ecu and turbo he was running 350-400 whp what injectors will I need to run this and what will I need to see the same hp figures? All help would be appreciated or any input thank you

upgraded fuel pump... probably 720 primaries 1680 secondaries. You might be able to get away with 550 stock primaries. Oh... get a wideband o2 sensor so you don't run too lean and blow it up!

You can NOT vary the primaries and secondaries too much on the Rtek 2.1 or the transition will be like crap.
Rule was about 25% variance.
850 and 1200's would be a good transitional setup.
I had 750/1000 but ran out of fuel on my stage3.(duty cycle was like 95% and very IFFY.)
You can get better info in the RTEK section of this Forum.

Whats a good wideband to use? And is the rtek pretty easy to use? I will eventually figure it out but ive never actually tuned maps and timing etc. Its a little scary to me and would I have to run a boost controller or does the rtek have that

But all in all, do some reading. the BNRs have been covered and there is a whole Rtek section here: https://www.rx7club.com/rtek-forum-168/
