Turbo Upgrade

[dregg100]

i went from stock to T4 on my FC and it is back down again for T6. depending on the size of your streetport lag really isnt that bad. and in my opinion it is really fun, because you have nothing, nothing, nothing, and then OH MY GOD!!!! the lag is really only there when you first get on it. between shifts the turbo stays spooled(this is with BB, i dont know about journal bearing) so when you hit the next gear it throws you back again with no wait.

as far as the BNR turbos go, one of my friends has the stg 3 on a stock port s4 and loves it. he actually has simillar mods to you. but i have never used any of them. then you also look at price. the comparrisons go on and on...

the biggest thing i would suggest is a full standalone as that will net you the most power out of whatever turbo you go with. just make sure you get a proper tune and not some basemap!
