Tino, the Olds Aurora is a quite literal race engine (Shelby Series 1, Oldsmobile Aerotech II), and it can take a phenominal amount of power with the stock internals (The CarCraft from March had a Aurora-powered car with two centrifugal superchargers ramming enough air down it's throat to make 560HP, on all stock block and internals). However, as best I can tell, it still suffers from the difficulties of adapting a normal Northstar engine to the Fiero, as it is a rather complex ECU set-up. Can it be done? Certainly. Would it be easy? No. ------------- Never shift into reverse without a back-up plan. |

| Yes u can make lots of power with these motors.getting the motor i think can be done but the ECU is my consern find some 1 that can reprogram it,this car is fully load with key chip and computer for fuel range,trip counter,distance and you can moniture the oil,oil life,trans oil life and other think all buy push of a button.It is a comlex system on this car so many features.the car has lots of get up and go for a heavy car. |

Well, have you tried searching Pennock's to see the Northstar conversion process? It'll be no different for the Aurora. As for stuff like fuel range, they normally run off a myriad of sensors, some of which don't even exist on a Fiero. Might be better to simply leave those features alone. ------------- Never shift into reverse without a back-up plan. |

There's no threads about the Northstar on Pennocks? ------------- Never shift into reverse without a back-up plan. |

That's odd, I did a quick search at Pennock's for http://www.fierosearch.com/cgi-bin/search.cgi?start=1&forum=-1&where=SUB&SearchQuery=Aurora&Action=DoSearch&datesort=D - Aurora and came up with 62 hits. Must be a couple of those threads dealing with engine swaps. A quick search for http://www.fierosearch.com/cgi-bin/search.cgi?start=1&forum=-1&where=SUB&SearchQuery=northstar&Action=DoSearch&datesort=D - Northstar brings up 660 hits!
