what is the best combination to use in a 13bt running 450-500hp
1000cc in primes and 1700 in sec or 800cc and 1700 or 550cc and 1000cc or 880cc and 1700cc are the s6 sec and run them in the primeries im lost |
Well you could probably run stock primaries (550) and run 1600 secondaries. Or maybe 850 primaries and 1200 secondaries. I run stock primaries and 1200 secondaries running 18psi making around 425hp, and I am staying at or below 85% duty cycle at 7500rpms.

i would get stock primaries and just get LARGE secondaries as long you plan on running alot of boost

1600 cc secondaries would be a good idea, but you'll need a new fuel rail. 1200's will bolt in. If you can deal with it you could go with 1600 cc primaries as well, but 850's should do the job well. Just make sure that you have a fuel pump and regulator to handle it all. Another popular setup is something around 1000 cc all around. When all of the injectors are the same size the transition can sometimes be a little smoother, depending on the ECU.

That's what I have in my car. I had it idling at 750-800 RPM, but it's smoother when starting from a stop with a 1000 RPM idle. There are quite a few people running that setup, but it's not widely practiced. |

i'm also kind of wary of relying on 9 year old cleaned and balanced nippon denso injectors. i RARELY hear of the bosch 1600cc injectors failing https://www.nopistons.com/forums/pub...IR#>/smile.png |

The 86-88 rails are aluminum and can be bored out for 1600's, as well as tapped for AN fittings. |

If you try 3/8" NPT you may go through to the outside if your hole isn't perfectly centered. |
