no..the standard T25 turbo will not maintain more than 14psi anyway. It will spike to 18 psi maybe, but will throw out your fuel mixtures and burn a hole in the top of your pistons on a hot day with poor fuel.

A full stocker should be run at 12-14 max if you run premium unleaded. And 8 or less if you put normal 86 octane normal unleaded.

To be honest..you should always have the budget to have a second engine ready. So many young fellas turn up the boost, blow the turbo or engine, and then end up driving their mum's barina (corsa) around for the next 2 years until they can afford to fix the car..
