I'm not worthy to have the original Bubba Joe comment on my build. His streched fiero is the inspiration for this build. I guess I need to post some progress. You guys keep me om my toes.

I got the engine and tranny mounted to the cradle hopefully for the last time. Here are some pics.

It seems like the 84 Fiero was the odd ball when it comes to wiring but I think I got it figured out. My goal is to get the engine installed and get it started. The ECM is a 7730 with Ryan Hess's tune for the Northstar. I know at will run because I had it running on the cradle earlier. Now I just need to connect it to the fiero's wiring. I also welded in a battery holder. Here are some more pics.

I have been looking at building a set of 180 degree headers once I get the engine running in the car. Has anyone had any experince with 180 degree headers on a V8 ?

I have wanted to do this exact thing for years. Glad to see that it looks like I imagined. Only difference is that I plan to use a LS3 motor vice the N*. I will also lose the rear wing or use a different one and I'll use GT tail lights.

Great looking metal work too. nice looking mods to the cradle.

Please add more pics when you can. More of the car from different angles.

dam nice job on the cradle but I would have mounted the battery in the rear for more space around the engine still love the true rear engine design

I think it looks fantastic, too. Great job so far. Someday I may tackle something like this. Always wanted the engine longitudinal.

Now for my opinion: The only thing I would change would be the battery, but unlike Bubbajoexxx, I would move it up front.

Keep up the great work.

Bob

PS: you skipped something...What did you do for the adapter plate?

Adapting the Northstar to the Audi trany was tricky. I spent many, many hours trying to figure out the easiest and least expensive way connect engine and tranny together. I don't know how much everybody knows about the Northstar but the water pump is at the back of the engine where the tranny mounts. Along with the water pump there is a big alumium piece called a water log the connects the two heads and the contains the water pump. This water log interferes with the tranny mount. see pic.

One good thing is that the Northstar has thesame tranny bolt pattern as a 60 degree V6. Kennedy Engineering sells an adapter for a 60 degree V6 to a Audi tranny. So I bought one. I figured that they did the hard part in getting everything lined up but I knew the adapter would need to be modified to fit adapter around the water log. The big problem is that where the adapter needs trimmed there is a alignment dowel for the Audi tranny. What I did was to mount the adapter to the tranny with both alignment dowels between the adapter and tranny. Then I drilled a hole through the adapter into the tranny and added my own dowel/pin. So now there are three alignment dowels. Next I removed the adapter from the tranny and cut the adapter to fit the Northstar. This cut removed one of the original alignment dowels but I sill had the other original dowel and the one that I installed to keep the tranny lined up to the adapter. Next I had to notch the tranny bellhousing to match the adapter and fit around the water log. I had a local welding shop weld in a braceon the belhousing just for extra protection. I don't have any pics of this procedure just the finished product, tranny mounted to the engine.
