i need to buy a new turbocharger for my 2000 s40. there are some on ebay for relatively cheap. they look completely different, but i don't know if they will work regardless of shape or not.

don't know the difference between these turbochargers:
GT45 TURBOCHARGER 700+ HP T4/T66 3.5" V-BAND 1.05 A/R | eBay
Mitsubishi Turbocharger | eBay
BRAND NEW GENUINE OEM TURBOCHARGER FOR VOLVO S40 & V40 | eBay
Volvo S40 V40 Rebuilt Turbocharger 2000-2004 | eBay

is there really a difference in performance between these? is it noticeable?

fyi, i'm not some street racing dude with a suped-up car... i'm just a normal guy driving in normal city conditions driving a normal volvo s40.

 

I have a 2000 s40 that I am parting out. If you need the turbo I will sell you this one for next to nothing. PM me
