It's a 1990 Suzuki Sidekick 4x4. Manual Transmission with Manual Locking Hubs, and 4WD Low and 4WD.
It's a 1.6 Liter 4-cylinder engine.
Is there anything I can do to it that would increase the performance of it for less then $1000.
Is there anything that you would reccomend to do to it so I could drive it in the woods.
Any other tips or special knowledge I should know about the car would be greatly appreciated.
Hmm ...
Congrats on being a new zuk owner ...
My suggestions,
get a FSM (Factory Service Manual) ... probably about $40
Change ALL fluids (oil, diffs, tranny, etc).
Give it a tune up (plugs, cap, rotor) ... probably about $50
Adjust the valve lash ... DIY with the FSM
You will now have increased performance for $100 or so! The bonus is it will be a reliable and dependable vehicle.
If it has >150K miles I'd guess a timing belt wouldn't be a bad idea either.
If ya wanna offroad it, add spring spacers and a bodylift (under $200), and get tires/wheels (say $600).
That's how I'd spend your $1000

<edit> ... cripes that's how I spent mine
