would u upgrade the fpr with 850cc and 1200cc secondaries? any advice would be appreciated

 

What are your mods and horsepower goals? I'm running 850s/1300s with Supra TT pump for a fuel system--no fpr. I'm looking at making 400 to the ground on pump gas with the BNRs.

Check these links out, full of good info:

hope this helps--
