i currently run 320hp on stock turbo and stock ports, maybe more soon.
 
J-rat on RX7club.com has from what i know produced the highest hp on stock ports with a large turbo. from what i\'ve read he has produced around 450-500hp...

Presume with a bigger turbo you could probably squeeze out over 300bhp - but TBH most people who upgrade the tubby would mathc it with appropriate porting etc.

standard RE ports are massive in comparison to 13BT or REW ports, so that doesnt count :Nono!:chat
