I'm thinking you might end up going with OBD1 electronics to run the engine, I don't think Ford has a stock OBD2 computer with a manual transmission for that engine, I don't know that for sure though. If you went back to OBD1, you would likely want to be using a 1993 and previous foxbody computer and wiring. Ford even sells the wiring kit for engine swaps. I don't know what kind of trouble you'll end up with when you do that, you have pats
and such. It might take some research to figure out how you want to do this. Most people that mod SBFs use OBD1 stuff. If you want to have a stock OBD2 engine from Ford, you might want to look at either the modular engines or an essex RWD
from a mustang.
I did some measurements a long time ago, but I can't really remember my findings. I think the firewall clearance might have been an issue, but I can't remember. You really need to grab a tape measure and start writing down measurements to see what will work. You probably have enough side clearance.
The exhaust will have to be rerouted and that seems like it might be a headache.
I had this planned out to some degree. I was thinking of adapting the Pinto/Mustang II IFS
suspension and ditching the subframe. It is one of the most popular suspension swaps out there, mainly because:
1) Massive parts aftermarket, like big brake kits, drop kits, etc...
2) Very compact and easy to install
3) Double wishbone design
4) Cost effective, for what you get
The crossmember that it is based around would add a lot of the structural rigidity back to the front end, seeing as there wouldn't be a subframe. You can buy a universal kit for less than $300 on ebay, then you need to buy every component for it, which should probably be under $1,000 to over $3,000, depending on how far you want to go with it, like chromed parts and such. You can also buy complete kits, but they are usually for specific cars.
I'm thinking it would be best to have a column shift Taurus, because the new transmission tunnel will not clear the stock floor shift/dash setup very well.
I would look at either buying a complete low profile serpentine kit or put something together yourself. Install a Saginaw TC steering pump (aka GM Type II, Ford CIII), don't go with the stock CII pump, that thing is pathetic.
Does anyone know how much capacity a stock Taurus radiator has? Will it cool a stock 5.0L V8?
