Not worth it. Tried it 10 years ago.

I tested this swap with my 4g93 1.8 single cam. The sohc ecu might not support it so well, I ran into engine response and drivability issues
At +6000rpm, basically it feels it is running out of air and fuel.


Eventually I put back my ported single cam in. The low rpm torque response of the bigger block (I had 1.6 high comp pistons) is so much better...you get almost all your torque by 3500rpm vs 5000rpm.on the twin cam, which means city driving and mountain road driving is all that much better. Don't forget the sohc head is lighter and has less parasitic losses, so the engine, with lighten flywheel, actually feels more lively.

If you are not adverse in doing an engine swap and registering, just drop in the 1.8 sohc. It's very cheap. Direct drop in.

On my lightened satria (950kg), passengers comment my car feel turbocharged due to that instant torque response. I recorded about 7.5 to 100, which is faster than the 4g93 dohc in the (albeit, heavier) satria GTI
