Yeah, different turbos will put out different HP at a given psi. But a stock block Zetec can easily do 200whp and up to 250whp with the right turbo, intercooler and tuning and 93 octane. Turbotom's 300whp on a stock Focus was done on 100 octane only.

Tuning is the expensive part. The most boost you can push cheap is 5-7 psi and that's anywhere from 150-200whp depending on your setup. Anything more than that and you need serious fuel and timing control, and bigger injectors.

Also remember that your stock MAF is only good to 5v then it cuts off fuel. That's around 8psi and won't get close too the redline.

As for turbos, I'd stay away from KKK cause...they're the KLAN, come on it's in their name. Seriously I don't know anything about there stuff except upgrades and rebuilds can be more expensive than more commonly used turbos. Stick with Garrett if possible.

Well I thought the Zetec injectors were good up to 175HP? 200whp would max out your injectors quick!
