84' 1500S DX hatchback Preformance

[TMB]

Just a few questions
1. Where can I find a good selectino of Preformance parts for it?
2. I've looked at lowering springs and only found them for the rear and it says the front is adj. I can't figure it out.
3. Are there any newer engines (90's or higher) that will drop in? If not are there and kits to make them fit?

I'm wanting to make it into a sleeper car.

Also it has the following motor in it
EW1 1.5 12V SOHC CVCC 3bbl Carb 1488
What can I do to get a few ponies out of it that wont cost an arm and a leg?
