Re: From T25 to T3!!
 

lots of different T25s, lots of different T3s. You should have more HP with the same amount of boost. You are going to be less likely to run out of the turbos efficiency so you should have a fall in boost pressure. I would highly recomend converting to an external wastegate when you do the swap for dead-on boost pressure without spikes or creap.
