Even fitting the 2 litre inlet manifold and carb on its own really improves things but if you couple this with the 2 litre camshaft then you will have replicated the 90 bhp 1.6 S engine.
I still never know why Ford didnt standardise on it as the build cost difference per car cant have been more than £ 50. That the 1.6 LS and 1.6 Lasers had less power than the earlier 1.6 S seems quite odd.
The 1.6 GT/ S head had bigger inlet valves and was better gas flowed than the standard 1.6 and they also had a 4 branch exhaust manifold fitted as standard.
The same applied to the 1.3 and 1.6GT versions of the MK1 with the Kent engine, better cam, twin choke carb, bigger inlet valves and 4 branch manifold.
Fitting 2.0 Cam, twin choke 32/36 carb and four branch manifold would I guess give it 85 - 87 BHP so long as it had the viscous type fan or an electric one. Probably still a worthwhile upgrade.
