Hello everyone welcome to the forum. Congrats on finding some nice stock cars.
Please read the other sticky threads, download the factory service manual for your year and get yourselves some nice tools and get to work.
Please refrain from
-stripping the interior unnecessarily
-any hipster trendy shit
-dumb stickers
-cut springs
-primer paint jobs
-avoid buying knockoff seats
-Chaser aero
-loud exhaust on stock ka
-Megan racing
-Isis
-Godspeed
-don't buy any body kits if you cannot afford paint
Please do
-much needed maintenance
There is a thread on this somewhere with more detail, but oil change, plugs, air filter, and distributor cap, transmission oil change, and differential oil change
possibly new tires and new brakes for your car
-learn to weld, you could probably weld better than the 5 year old chinese kids from all the knockoff companies
-Learn to do proper bodywork if you want to repaint it, or understand the costs of a proper paint job
-Learn to solder ( super easy)
-Learn some proper budgeting and save up for quality parts versus buying shitty parts NOW
-take a lot at what the average costs are of a rebuild. Make an excel sheet and start listing part by part what the costs are
-read some build threads here and on zilvia. It's a good source if you want to creep on but I generally dont suggest to interact with them since everyone loves to argue with each other
