what goes into making a turboed g40?
« on: March 08, 2008, 12:39:41 pm »
i'd really like to buy this summer a conversion g40 or something i can play with and loved yoofs turbo.  now im clued up with the g40's but dont know enough to start building my own turboed one.

assuming you have a decent py whats the main stuff you'd have to buy to get started  engine wise only...  

lets say for about 180 bhp-200 bhp.

correct me if im wrong but a down pipe?  where from?

A turbo, but which one and where from?  someone explain the differing ones ko2 ko3?  whats this mean?  

injectors?  which ones?  


oil cooler?

etc etc?  fitting, im not worried about.  knowing whats needed - my issue. :wub:

any info or a thread that goes into detail but still keeps it understandable would be interesting.

My blog on Club Polo covers most of my turbo conversion if memory serves.

hi from bulgaria :)
here we have .. maybe 10 or little more g40 :)
one is mine :)
my friend mgm (milen) have polo g40 too .. he has g40 genesis but try to insert in it one street lamp :D

this is milen's g40 (t40 ;))
1/4 mile versus Audi S5 (14,75 secs)
and this is master driving :)

tomorrow i'll try to find a engine pictures
what you need.. hmm
milen's exhaust system is f63mm
exhaust mainfold is handmade
but because the master of the mainfold was a big fool milen have to made flange for oil filter :)
you need new oil path to turbo (with more f) and restrictor for oil path
need downpipe too... again DIY
if i remember more i'll write again :)
