Garrett GT 1749v turbo

hey guys i have a couple questions but no one seems to beable to give me a straight answer about it.... i have a 03 vw tdi with a cold air intake and i straighted out my muffler but i was look at a turbo the Garrett GT 1749v someone i know tells me i should beable to run this no problem in the car no need for injectors or anything like that but someone else i talked too told me i need bigger injectors ecu reprogram lift pump billet lines and more just to put the turbo in is this true

the 1749v is the same size as your stock turbo... it's not an upgrade. it *is* a mild upgrade for an mk3/AHU car because it's a vnt that fits the mk3/AHU with little modification. but it's still a vnt15

the stats say it goes from 100whp to 175 and torq from 177 to 250? not an upgrade

what would you recomend for an upgraded turbo if not an upgrade

Thats a hell of a salesman to sell you a turbo you already have!

i like the "17/22" hybrid.. idparts.com sells them. it's odd that someone would suggest to you a 1749v.. it's not a very common turbo here to suggest. the only people i know who run them have put them on mk3 or mk2 ahu engined cars (eg, 1998 jetta tdi), since that is a mild upgrade. it's one of the few vnt turbos that fit that platform without modifying motor mounts. what stats are you looking at?

With some bigger nozzles and the right tune you'll get around 150 bhp and 300ft/lbs of torque with what you have on the car

With the 1749v what's the difference between that and the 1749vc?

If it's anything the same then surely it'll be an upgrade, no?
