So now im just feel like i need some upgrade for the engine..
1st thing..i dont like a turbo ( i dont need big HP)
Here some list that i want to do:-

1. Change transmission from auto to manual (i just get one and just wait..under construction)

2. What type of hi Cam & cam pully that i can use.

3. Piping exaust.

4. Racing clucth.

5. Piston?

I need some advise for more engine improvement..maybe change the big piston 😂

6a12 non turbo have very weak manual transmissions. The differential likes to go bye bye on them.

The only way to make power is with turbo. You can do a single turbo with whatever is available in your country - garretts or whatever. You can make decent power on 8-10 psi of pressure. You can buy a MAFT online, I'd suggest MAFT gen 2. Its a bit more expensive, but its well worth it. You can also tune it with SAFC which is less expensive. I've run upto 15psi on a big turbo and stock ECU with SAFC

Exhaust from 2g eclipse fits with some extending and I wouldnt go bigger than 2.5 inches.

Cold air intakes and other mods dont really work.
