i konw i was just pointing out the fact that MANY people have high power setups with internal wastegates and it works great. and for 230-250whp internal would be perfect and less expensive.

its smarter to just buy high quality parts in the beginning and not expect them to break rather than to spend more on parts you think might break because its easier to fix..

i agree with you that you should buy high quality parts in the first place but have you seen the opening that an internal gate provides for exhaust flow compared to an external gate? the smaller the opening, internal gate in this instance, the more prone you are to get boost spikes, especially when you start turning up the boost, whereas with an external gate that is matched properly to the setup will geve you essentially no spike at all. not only that, but adjustable wga's further the spiking problem. even a 35mm external gate is bigger than most internal gates which will result in better boost stability and lessen the chance of having a spike that may be detrimental to your motor. my thinking is that you might as well do it right and safe the first time and if that means that you spend a little extra money on getting an external gate then do it and don't worry about whether a spike is going to be the end of your motor.

that makes sense completely.. but the OP wants 230-250 whp.. which on a zetec can be achieved with 10-12psi.. not high by any means..

its all in what the end goal is..

yeah i know, but for reliability and for possible future upgrades, it just benefits to start out with the external.

BTW, i looked at your cardomain, nice car. have you painted the wing or are you going to? i couldn't tell from the pics.
