Cheapest car to modify for speed

Hey guys. What do yo think are the top 6 cars that are best to modify in terms of horsepower/torque easy gains and unlocking potential, handling, fun factor and price?

List the reasons why...

Please no flaming.. and please be ready to backup your arguments with cold facts.

I personally like to modify older cars but if we're talking about the last 20 ys or so.

87-93 Fox mustangs. The cars are light, the parts are cheap and the aftermarket is larger for this model than for any other car in history. You can put together a road course killer or a 1000+ HP strip car for under $20K.

GM G-Bodies. The Regal, Cutlass, Grand Prix and Malibu from the 80's. The last RWD, ful frame GM car. Aftermarket is huge, cars are cheap and they are everywhere. Like the mustang you can build anything you want cheap. There's room for anything from The 3.8K turbo six to BBC's with huge turbos. The only down side to these cars was the somewhat flexible frame that requires stiffing at a couple of points.

Gen 4 LS powered F-Bodies. Cars are way too heavy but the LS motor takes mods very well and has proven to live a long life under forced induction. I've personally seen these motors live making 700HP for over 100K miles. The rest of the car falls apart the motor lives. The 4L80E trans will take the beating stock as well.

Nissan GTR. A bargin super car with a major potential. A couple of quick changes for under $2500 and you have 600HP. The rest of the car can easily handle the power so no harm in upping the power.

Subaru WRX STI. Like the GTR the mods are relativly cheap and big power can be made. The car itself is well built and takes the additional power very well.

That's about all I can think of at the moment.

Now I'm going back to the garage to work on my 5.3 LS swap in 72 Monte Carlo.

I've watched some videos on the Subaru wrx sti...man they are animals...

The only problem I have with them is their styling. It's just to boxy and butch looking.

I am a fan of the LS engines.the sound and feeling of driving one is incredible. There's nothing like sitting behind the wheel of a car with massive displacement.

any pre 96 jeep wrangler. a 90 with a carb for sure. not for street but for wheeling!

I think my list of cars I wouldn't modify in some way would be vastly shorter (a couple vintage cars and a couple exotics really) than the list of the cars I'd modify. I've modified most every car I've had, or wanted to (leasing the MINI Cooper has kept me from modifying it), in some way, be it for more speed or better looks or both.

I've always wanted to do a DeTomaso Pantera. Great car to begin with upgrade the brakes and suspension components.I've even seen some guys put big block Fords in them
