hi HT,

i got my hands on a gerret turbo (dont know which one) but its a BB type, i'm running a d15b vtec with a pr3 ecu chipped my xenocron on my rex, i have now IHI subaru impreza turbo, its a small one and the garret is bigger one, will i have an increase of power with the tubo swap at the same PSI?!

what is different between BB turbo and normal ones?1

thanks HT in advance
