You could get a godzilla kit to spool good on a 4e if your prepared to spend money on uprated intake manifold, headwork, cams, raise the revs to get the most out of it, maybe some nos to help to. But if your coming from a hybrid ct9 to that sort of set up you probably aren't gonna like it as it will take a while to spool up, so maybe td04 would be better & if you decide you want more power you can just get a td05. You need to decide what your gonna use the car for, & whether you want to sacrifice response for more power & how much money you wanna spend in the long run. Im running a gt28rs & it works well on a 4e, I think this turbo is probably best of both worlds, can produce over 300hp & the lag isnt bad at all on standard head etc, but its more expensive than a td04 or 05.
