MK4 gti turbo up grade

im living in gloucester

You have got bill at badger5.co.uk local to you.

If your only wanting 200bhp/220lbft then your best best is to stick with the Ko3 turbo and get a good stage1 remap with full exhaust system, the stock air box will be fine and fitted with a panle filter.

Hi ive got the golf gti turbo with AGU engine fitted, its a T reg 1999 i wanted to change the turbo to a K03s as i under stand mine has the K03 but after been looking into this i have also found out that mine has smaller injectors

First off what is the differance between the K03 & K03s?
also if i change to a K03s will i gain more power?
could i fit green top injectors into it and will this help, i under stand that the green top injectors are standard spec for the G60

Please can someone help me

Cheers
Craig

An idea of power from a tuned K03s turbo back to back with stages.
