Preparing my Fiero for an engine swap (Page 17/23)

Wait until you have a laundry list of items that need verification by putting the engine + cradle into the chassis. You'll minimize the total number of "in and out" times.

Freya was on the road yesterday and will stay on the road till the salt, hopefully to Christmas. Shez a daily driver. We came across some stuff we wanted and since the dump truck was in the vicinity we had to do what we had to do.

i did some crawling under her and realized i had not accounted for the drive shaft. Such things are why i only tacked it, but the hard work of making the motor mounts was the grinding to fit the stock mount, not the extreme exterior.

i would like to get the belts on and the stuff welded up, but i have only one alternator on Freya, and the one from ol Betsy is seized up and the case is cracked, but maybe i will use it as a template to get the alternator bracket fabbed up. But other stuff as well, like the dogbone, the left hand dogbone from ol Betsy seems to be the right size to fit on the right of Freya, but i won't know till its in the engine bay. Might not be adequate in any case cuz its aluminum. So much to decide, but i got all the bolts out of the block from the exhaust manifolds. Only one bolt left - for the EGR tube. Can't seem to find a socket to fit. What to do?

i bot a T stat housing for a duke. Gotta modify it, by cutting off the bottom and welding in a custom part. Question: do i need to keep the little tube at the bottom of the housing?

Thermostat housing is coming along:



Belt routing proposal for low mount alternator:



Looks like the cardboard alternator bracket proposal needs to be raised up a little bit. i will have to design/build it with the dogbone/tensioner bracket so i can make sure that the belt doesn't rub where it shouldn't.



Has anybody done the heater hose return like this? Using the stock plastic elbow, but they sell upgrade kits for the 3800 with metal elbows. How to hold it in? A cuppla set screws drilled and tapped into the waterpump?

Or you could tap the elbow port (3/4 NPT) and install a hose barb.

I hate to tell you this,but your belt routing will not work.The idler belt pulley on the coil bracket will hit on the trunk hinge bracket. I've done a couple of these and it's always the same.So slide the engine up in there before you finish your routing to see how much you need to move that pulley.Depending on where your engine is placed on your cradle will dictate how much room you will need.
Just trying to save you work.

Would i need to drill? Cuz the taps are available on amazon for $17C free shipping.

thanks

Do you have a pic of or a thread for your solution?

No drilling required.
Don Kraus MAY 06, 11:14 AM
It's been 15 years since I completed it and 16 years from when I started it,so my memory isn't real clear.But I know I removed the coil bracket that had the idler on it and made a bracket to hold the coils and that was bolted to the exhaust manifold bolts.Then I used the bolt hole from the bracket in the front of the head or another empty bolthole in the head, and bolted the idler to it that I took off the coil bracket.You may have to shim it to get it aligned and you will need a different length belt.The belt will end up being close to where it comes around the spring loaded adjuster pulley.You may need to get a different diameter pulley,I just don't remember,sorry.You will want to mount the coils somewhere other than the back of the motor,it will make life easier.They can go anywhere.
Here's a picture of it,you may see enough to help.It's the best I got.
Over the years I installed two 3800's and a 427 V8, all with the 4t65e auto transmisson.None of them required cutting the spaceframe or anyother part in the engine compartment.
Hope this helps,good luck with your project.
