With a bridge port and the proper carb setup you could theoretically make power over 10k. I know of a person making decent power to 9.5k with a large street port and ITB's, so its can be done. If the engine doesn't have a bridge or larger then it is truly pointless to go much over 9k.

 

the engine has a j port already so yes it will make power up there. And i am NOT going EFI the whole point of this build is to stay with the Holley 4brl carb setup.

 

You don't need a j port or a p port to have power up that high. IPRA Race cars in Aus have what quite a few people would consider mild birdge ports and those motors are getting spun to 11K+ and making power. They use radically different intakes than most people on this side of the pacific do.

 

Do you have a special close ratio transmission that was designed to be shifted up that high? If not, give it up. Too many people want to rev higher because more must always be better. It's not most of the time! You need to have your engine and drivetrain match.

The Holley manifold is fantastic for street use but for an engine revving up as high as you want to an IDA setup would be much better and more powerful. No point in revving that high if your setup isn't optimized around it.

 

SO..how HIGH can you go with stock coils & Igniters. ALL else being Irrelevant!

 

That's actually a very good question. The stock coils on the 2nd gen are fantastic. I personally would not replace them with anything else as I have yet to see anything else better. This includes coils from MSD, etc. An ignition amplifier might be beneficial but the coils themselves are fantastic units. You need to be careful though with some of the ignition amps as a rotary really likes a big strong initial spark over a short period of time. Many of those boxes give multiple sparks over X number of degrees instead which is great for some engines but not optimal for a rotary, although it does work. If you have a standalone ecu in which you can adjust dwell, you can also get varying results with different rpm limits. Get too greedy on dwell and you'll even fry the coils at low rpms. There are many variables that can affect the overall limit but the coils themselves are actually very good units.

 

What about LS1 coils?

 

Actually, the (stock OEM) twin tower wastespark leadings design sucks.
Going with individual coils per leading and firing them simultaneously is superior.
