1. Engine Swap G13BB/G16B (Whatever Fits In The Budget)
I can get a G16B (Rare) or a G13BB to swap into the Cultus which previously has a G10 Carby ! Only the limitation scares me as I know that I will have to get custom mounts made for it and all wiring done from scratch. Here in Pakistan, labour is cheap, engine swap is done for 2000-3000Rupees which means $68.18 AUD.

Cost Estimate :
G13BB Engine : $900AUD
Swap Cost : $60AUD
Wiring : $50AUD
Suspension Setup From Baleno : $200AUD
2. Engine EFi Conversion G10 (It is Carburated frm the Factory)
I can get an aftermarket standalone ECU to manage Fuel + Ignition ! And then later on put in an exhaust and stuff to boost the power. This would involve fabrication of a custom Intake Manifold which is difficult.
Is there any other intake manifold frm an EFi car which will bolt onto the G10 ?
I dont know abt the estimated cost but it would be same as OPTION 1 !
3. Engine Modification as Non-Efi
This would be easier and cheaper but I dont think it would be much fun like OPTION 1. This option would involve a Weber frm Australia

Estimated Cost :
1. Weber (Brayden plz help

2. INtake Manifold (Not Confirmed)
3. Headers $70AUD
4. Exhaust (Muffler + Piping 1.75") $90AUD
5. Iridium Plugs [NGK IX] $55AUD
6. Performance Wires [Magnecor] $35AUD
7. Performance Coil [MSD] $140AUD
8. Compression Increase on Spare Head [10:1] $150AUD
Please give your advice as all of you are experts and im a beginner. Which option would be better ? Considering that I cant keep my car in undrivable state for more than 2 days ! Cheerz !
