What Midnight said! The XSI is the worst engine they did IMO. You have the sluggish bottom end of the GTi engine but a seriously detuned head like the 1.8. The 1.8 is a great base for a build as its a very lively engine and substantially lighter than the XU10 (being all ally instead of iron like the XU10). The GTi engine is already highly tuned from the factory so takes a lot of money to get any substantial power gains from it.
