Bnr s3 upgrade help

So the time has come to upgrade my turbo to a bnrs3.:afro:

I will be doing the install myself,is there anyone who knows whether i need to upgrade or change oil/coolant lines or will the oem stuff just connect straight up to the bnr?

I have ordered a new 3 port ebcs,3 bar map sensor+harness,but am a bit lost on what is required with upgrading the maf to a 3",i currently have a cpe cai and cpe tip,and from what i believe this should connect straight up to the bnrs3,what needs to be done to upgrade the maf?

The BNR is an upgraded stock turbo so all oil/coolant lines should fit just like stock. Like RedDjinn said, you will need to have the tune calibrated for the 3" MAF, and the 3bar MAP sensor.

To upgrade to a 3" MAF, you will need to get a different intake. I recommend the HTP 3" full intake as it will fit with the BNR and with the stock battery tray.

Let me know if you have any other questions :)

I would recommend all braided lines too.. you may as well do it properly

Thanks everyone for the help. @dazza,do you know if there is a braided lines kit you can get or do they have to be custom made?
