Hi folks! I have a vwT4 with an aaz engine full rebuild and I need recommendations on the setup, I want to reach 110hp aprox and be reliable for every day.
I am adding a front intercooler, oil cooler and a 5th gear modification.
I'm in doubt as to which turbo and how many millimeters of pump head would be the most convenient.
I have 2 turbos that could use a k03 38/46 wheels and a GT1749S 44/49.
Do you think any of these would serve this purpose? And what size pump head do you recommend?
Thanks for your time!!!
