for practically + horsepower, u can buy a 4G92 Sohc or Dohc (Sohc for low-mid pull, Dohc for mid-high pull....but in the end of the day skills matters the most) strip the engine n complete rebuild and blue print it. Putting a 260lift cams and port n polish the engine head. Replace all pulleys with aluminium ones. Remember to add an Oil-Cooler for pleasant high-revving obsession....Hook up Emanage or Unichip and You should be enjoying about 130-140whp / 150-160wtq at it's best. (Under skillful hands, this sohc 92 can be very competitive againsts mivec and vtec)
Estimation is RM7000-8000 for such project (just source engine lantai + ecu + injection kit will do)
For handling, use Enkei rims 14" - 15", using good tyres.....Get a fully-adjustable suspension is more crucial, test drive it n get used to the handling upon ur own preferences
(chassis stregthening is the last thing u want to improve, coz stiffening chassis doesnt means is better handling most of the time, chassis needs to flex to ensure grip n prolong chassis life, too stiff might crack n spin out)
