I can see how any ct9 will be not much good higher up the revs so with my 5E build I went for is the TD04L it, I have looked into loads more different turbo's I suppose it's how you drive and what the car's for and not to waste money!
The hole point for me with the 5E is the bottom end torque I want most power come strong from the bottom to get away quicker I see builds with big big turbo's I don't understand having all the power coming in at the back unless your on long ass roads there's not much point imo I know they used a hybrid lol
