Hey guys,
Haven't been around that much so fairly new on here so go easy on me
.
I got 58 reg Jetta MK4 1.9 TDI and was wondering what's involved in changing existing turbo for a bigger one?
I have to say that I'm actually know very little when it comes to turbo. Was speaking to my friend who used to have MK4 Golf TDI and he said that it's possible to slap on turbo from either BWM 3.0 or Audi 2.5 and on top of that use the cold end from Audi 2.5 and result should be close to 300 BHP. He knows much more about theses things than I do so I have no reason to dispute what he says but still would like to get a further opinion on this matter.
Basically would appreciated any information i.e what's involved, cost, any additional parts and/or work required, etc.
Thanks in advance!
