#1 rule for a racer... Learn to make due with what you have to work with...
#2 Learn to fab stuff up and make it work be it for your car or not..
#3 To know that anything can be done, and most times it don't take money... Just clear thinking and the will to do #1 and #2
Think about the long gone days of yesteryear when auto racing 1st got started.. Flat head fords on the old dry lake beds. The guys then didnt have parts they could buy, or money to spend.. They made thier own parts, made what parts that was out there work, etc.
My point is that you have a good base to work with... Learn to fab parts..
You could build a twin turbo system for under $1,000 for your car if you wanted too..
Use your head, not your wallet.. If it's turbos you want.. $50-100 each junkyard used T3's, for duals.. T4 for single..
Buy a $400 mig welder..
An old set of headers.. look for used ones.. Cut them up, move tubes around, re weld them, weld on turbo flanges.
Some metal line and fitting from the hardware store
You get the idea..
If you rather throw a v8 in there, I'm sure the v8 made for those years wouldnt be hard to swap in..
I can't tell you about ford cars.. I'm a chevy guy, but on the 1982-92 camaro like I built, GM had drilled holes in the K member for all 3 engines.. (2.5L 4 cyl, 2.8L 6 cyl, and the SBC v8's)
Swapping the engines was just a matter of yanking the old one out, bolting in the right mounts, bending a couple things out of the way by hand, and sticking it down in there.
Next lets talk about type of racing.. Ever heard of bracket racing? It's drag racing where the winner comes down to the driver that can drive the best and knows his car the best.
In bracket racing.. You have to know what your car runs, be able to run that # back to back to back... Be able to cut a good light (reaction time), and know how the weather cond. will change your car's ET.
In bracket racing an 18 second honda can beat a 7 second outlaw street drag car if the driver of the honda is better.
