I'd rather boost the 2.0L SOHC than to even touch the 1.8T and here's the reason; Less parts, easy as hell to tear down, you can make these engines fast. And besides, it's been around for almost 30 years, so naturally, there's a ton of parts for it. the SOHC gained my respect years ago. Damn a 1.8T. The only thing to brag about it is that the internals are forged and there's 5 valves. It's a decent motor, but I'd still take the 2.0 over the 1.8 any day of the week
