20B turbos on fd 13B

Anybody upgraded by using the 20B sequential twins?
If so what did you think? Any input would be great.

its not a bolt on either. the cosmo 20b has a different bolt pattern, and the ports/ passages dont line up either.

Not a good idea. Spoke with Bryan of BNR about them. He said he could not rebuild them nor were they any sort of upgrade. The are much more restrictive "20% less flow volume," (THE MAZDA RX-7: Mazda's Legendary Sports Car, By Jack K. Yamaguchi and John Dinkel, 1992, 1st ed)

Do not buy them!
