Title: Which engine model do I have???
Post by: Jonny1.8T on 15 December 2009, 11:53

Hi guys,

Been reading this forum for a while and you helped me make the decision to purchase my first golf!

Got a black 3 door 1.8T which I love but I am not sure what the difference is between AUM/AGU/ etc?

Any help would be greatly appreciated :undecided:

Main difference between them being that engines from AUM + came with the better Ko3s turbo where as engines before it only came with the ko3 turbo.

They come with the same power but an engine with a Ko3s will see higher gains from a remap. Thats the main difference, there are others like throttle cables and stuff but to honest I cant remember off the top of my head lol

Having a bit of a blonde day I think. :embarassed: Just checked the engine block and it is a ARZ.

I was toying with the idea of getting it re-mapped but the car's done 70K and don't really want to put too much pressure on things. Had a bad experience with turbo's blowing up on a BMW once.

70k is absoloutely nothing on these engines mate!

I remapped mine at 85k,  and im running nitrous on mine and its now on 110k !

The turbos are good up to 130k

jwelsh is right, 70k is reasonably low mileage and many people, if not most on here have remapped their cars with more mileage than that.

As said ive been mapped since 70k now at 137k on original turbo  :wink:
