I'm looking into putting a Stage 3 or Stage 4 BNR turbo upgrade on my S4 Turbo II. I've got the S5 turbo now, waiting to be upgraded. I was wondering if either of the stages would require a stand-alone, and what other mods I would have to have to get the full potential out of the turbo.

I'd also like to hear some people's likes and dislikes about each stage.

Thanks guys!

 

this is the single turbo fourm... not twins.. but you might want to try generation specidic..

 

No kidinn ...duh its the "single " turbo forum..... Needless to say a working set of BNR stage III's ...you may as well be looking for big foot

 

FYI all FC3S RX-7's are single turbo, so this is the right section.
You might get more info in the FC section however since the single section is mainly for the FD guys who have something to make up for.

As far as your question, you could probably get by with an AFC, but why would you want to?
You could get a second hand Mircotech or Haltech cheap enough, that's what I would do anyway.

 

He's talking FC stage 3/4 turbos, not replacements for the HT-12 Hitachi's.

 

This is talked about quite a bit in the 2nd Gen forum. Just do a on BNR in the 2nd gen forum and I think you'll get more than enough info!.

Well, i posted in the gen specific, and some of the guys told me to come here and post. That may have been centered more for my ideas of getting a T-66 though. Sorry guys
