Default advantages in spool time of the 2.5 engine

i was talkin to my turner here and he says that going from a 2.0 to the 2.5 will get the turbo to spool around 800RPM sooner???

I want to get more power than tuned STi turbo which is around 340HP (MY04) and still keep low lag

so i am going twin scrool and getting a hybrid VF37 - making it simillar to the PE1825

but doing that with my stock 2.0 engine will make it a laggy turbo!:S so he suggested getting a 2.5 engine and putting the hybrid turbo on it!

he says he tuned a classic with a PE1825 and got 420HP and very very low lag. he even showed me the dyno and it looked pretty damn good



what do u guys think???

Circa 500-800rpm would be about right.

Theres 25% more gas flow on a 2.5 so yes you'ed expect to have a significant decrease in spool time
