That is the problem with these K03's...they're so small that you need to overspeed the turbos to get any decent flow, which results in alot of hot air off the compressor. If he's planning an building the setup and running feeble boost then they'd probably fit the bill..........I've yet to meet a Porsche owner who tweaks they're car and doesn't want more power

Ko3S cars are crank rated at about 220hp at 15psi, standard ko3 around 180 at 15psi. That's with the VE and head setup of the modern 20valve heads on the 1.8T I just personally think if he wants to do this to go for a set of Ko4's(it's why the S4 guys do it). You'd have a cooler charge temp at lower boost pressures(better for motor) and have more useable turbo/rpm range as well.
