1 mm smaller to be exact

this doesn't make sense or maybe i am just stupid

i don't think BNR usually does sequential if that's what you want. i think they usually are non-sequential. maybe you could make that request though.

OK, i just spoke w/ 3 people who said the BNR's they got were ****. One got a cracked housing back, after they charged for a new housing, second guy said the burbine was installed backwards, so from there perspective they have an attention to detail problem. https://www.nopistons.com/forums/pub...R#>/unsure.png

Their were a couple of guys on here that have them and like them. I have also heard bad things about them but then again I hear bad things about all Rx-7 products. It is completely up what you want. If you wont a twin set-up you only have a couple of options.

Ok, appreciate the honesty. https://www.nopistons.com/forums/pub...IR#>/boink.gif

if you get 99 twins you can get them NEW.........they will last longer than BNR's that is what you are paying for https://www.nopistons.com/forums/pub...IR#>/smile.png

i don't think you could install a turbine backwards if you tried.

yeah buy new turbos, ive never seen a rebuilt turbo go more than 20k miles

Okay now I am confused? Why is that?



And what is the difference between the BNR's and Pettits Upgraded Twins?



And I still want to know if BNR can upgrade the 99spec twins or is this pointless?
