    Caddy NorthStar...

    ???i was wondering what kind of performance the 4.6 northstar engine has in a fiero? does anyone know what kind of horsepower it cranks and if there is any aftermarket parts to enhance the engine? i've also heard you can use the caddy auto-trans, is this true?

    I don't know that much about engine swaps, but have seen http://www.chrfab.com/ passed along as THE site for Northstar mods. They've done some Fiero swaps too from what I've heard. Maybe email them and invite them over to this board to comment on the Northstar for us all.

    depends which engine you get

    they are rated 275-300hp depending on which year you get

    As for aftermarket parts, other than a free flow exhaust there isnt much out there. Of course you could do your own engine work. Decking the head & block, match porting & over boring the trottle body.

    It's a gorgeous engine, but no stick >

    The Northstar is an interesting engine to consider. Yes, a 5-speed can be done. A few user's on Pennock's have done it or are in the process of doing it. If you contact http://www.chrfab.com they can provide you with aftermarket parts to up it to the 400+ HP range. The engine weighs about the same as the original 2.8 V6, so it won't screw up the weight balance.

    The big downside? Price. It's an expensive swap. To do it right, you really need a stand alone ECM (i.e. Holley Commander 950, etc). But when done, you'll have a reliable, powerful, light and totally emissions compliant engine. It would be the natural choice behind a 3.4 DOHC, IMO. (or first choice, if you've got the money )
