I have so far been looking at modifications such as 4 branch exhaust manifolds and upgraded cams such as the Autotech Camshaft https://www.heritagepartscentre.com/uk/WC109AT10109418K-autotech-camshaft-1-8-2-0-16v.html if that helps to create an idea 👍

I'm coming up to one year ownership on my 1990 1.8 16v KR and am now looking for the best ways to increase its power output to hopefully around 160-180hp. The engine is completely standard currently and my budget for this is around £1000. So what would be my best ways of achieving this?
