well i was just curious on what kinda engine internals i would need for a realy Large streetported 12A, and turbo\intercooled about 10-20psi of boost , like would i need low comp rotors? and where would i get them if so, and what about apex seals and such , and also what would be needed for feeding this machine in your oppinion, and would anyone have any suggestions for ignition aswell, all information is appreciated thank you.

 

Use Stock 12A Rotors.

As for Boost levels,- it's all in the tuning.

 

20psi w/ large street port? thats alot of air = BOOM

probley just gonna colapse the faces of the rotors >=]

For engine internals you should get solid corner seals, FD corner springs, some kind of stronger apex seals(rotaryshack, ceramic, rotaryavaition), and depending on how high you plan to rev clearance the rotors and hardened stationary gears. Feeding it I'd go with a weber 50dcoe, or a weber style throttle body. Ignition depends on if you go fuel injection or stay carbd. For EFI the haltech will do the ignition for you, for carb get an msd box or two. You could run 20psi without any problems as long as the tuning is good. Start off at low boost, put it on a dyno with a wideband and make sure it runs just slightly rich. Then start increasing the boost, but make sure it never leans out. If you detonate a few times at 8-12psi it won't do much damage if any, but past that you'll start breaking stuff real quick.
