mr2 misfires if reved quickly

[mazdaluver]

Hey my mr2 turbo just had the engine rebuilt, I can only rev it slowly to reach redline, if you rev it quickly it will start to misfire at 6500rpms and not let it continueing to rev. When your driving it it will just fall flat when starting to make boost. do you guys know what it could be. its a '91 mr2

Thanks...
Dan.

How old are your ignition components??

[mazdaluver]

i dont know its all stock i guess ever since the car was made. cant figure it out.

I would try replacing your plugs, wires, rotor and cap. Sounds like the symtoms of old ignition parts.
