88 4cyl as suspension donor

I have a 86 fiero se recently purchased and soon after purchase replaced nearly all bushings in hopes to eliminate most twitchy behavior and now found the block was cracked and needing to be replaced rather then "rebuilt" like quoted.
So after doing a fair bit of reading I see my only solution is vast amounts of money in after market suspension for front and back going with fully adjustable everything or having a 88 donor suspension/body. As I wish to stay with the notch back i am looking at the 88 formula or coupe or as said transfer to my vehicle.
now ive run into a 88 4 cyl though the interior is trashed and extior bush bombed but still running the price cannot be beat. I never thought to look when i stopped to ask if it was for sale and now i find out when calling back the owner of the car is not so fluent in English so asking questions is out of the question. everything felt tight so hoping only minor replacements would be necessary.
my questions
#1 does the 88 4cyl have the suspension improvments im looking for and can i make them usable for my 86? since I will be having to do an engine swao(my block cracked) for a new v6 the engine cradle modifications are not avoidable with the 4cyl. front is also swappable?
#2 is there a rear swaybar stock in the 88 4cyl?
#3 will the front and rear bumpers bolt onto my 86 from the 88? pushing towards a formula look

thanks so much,
I have a week before i can meet with him again and any advise is appreciated.

Slight correction to the above....

The 88 cradle will not fit an early body directly.  The struts sit at a different angle, thus needing a kit to install them.  This also gives you adjustable coil overs in the process, since with the change of angle, the full size spring doesn't fit in the tower anymore.

Screw the front suspension!  Sell it to someone with an 88 in need of parts.  ;)

Rear sway bars were standard on formulas and GT's - not the base coupe.
(but as above - a bolt in if you can find one)

Take a look at this:

Don't put a front into the rear if you've gone to the trouble of doing an 88 swap.  Just find an OE one, even if it takes a bit.  Why reinvent the wheel?

well not quite all out, just have a belief of doing things right! I have been considering the Beretta upgrade but the equipment on the car is functioning well so it will be after the fact of the cradle swap.

I have the 88 rear in my '84/86. I used a held motorsports coil over kit/relocation kit and am happy with it.

 

The difference in handling is night and day.

 

I didn't do anything about a propotioning valve and the braking is ok on the street at least. I haven't run it in a course...I may soon.

 

I went with 300# springs in the rear, which is one step stiffer than stock and feels good to me. For increased performance, increase the spring rate, as this reduces roll, which is a high performance problem for even the 88 suspension according to racers.

A coolant line or two may need to be rerouted due to the link arms which go where the originals were (For my v6 application anyway).
