    I think I may be able to give this a go.

    Hey RedDJinn, are you running new new map sensor & 3" MAF?????
    With a 3' MAF you wont have any issues with the OEM sensor unable to read the flow.im running a 3' maf and Wilksy made airbox lol

    The stock MAF housing is 2.75" so if you upgrade to a 3" that will significantly alter the way your car runs (for the worse) and you will definitely need a MAF recalibration via a tune

    Question relating the bigger turbo.
    Can a 4inch tip even fit in the area?
    it looks awfully tight with the stock battery

    the cp-e, SURE & HTP are all 3" TIP that flare out to 4" where they connect to turbo
    the JBR is 3.5" flaring to 4"

    Doesn't someone make a full 4" now? Read something about it a little while ago, think it was on MSF..

    The CPe fits only because its made of silicone and gets squashed and is able to be deformed by the battery tray , if your going to use the JBR or HTA intakes the battery needs to be relocated or use a slim race battery with small battery tray

    Mods I don't have are SRI/CAI 3', TIP, EBC & a tune, YET ...... obviously. Is anyone using a 3 BAR MAP sensor with their upgrades????

    What benefit will I get from doing the exhaust mani??? In doing the exhaust mani, I assume that means porting to the head?

    A lot to consider then, I will decide between the BNR S2 & S3.

    I have spoken to a few installers & they have all said it is not necessary to upgrade either MAF or MAP sensors???? !!!

    im using a 3-bar, as is @rayd and @MPS2NV
    no point doing exhaust mani for the power you're running, stock one doesnt become a restriction whilst on 98, and you dont need to port the head
    MAF sensor itself doesnt need to be upgraded, just the housing upgraded from 2.5" to 3" or bigger
    MAP needs to be upgraded if you want to run more than 21psi of boost

    From stock, to GT3071, to substantially less modded, many lessons learned!

    Hey mate im (was) running 3 bar MAP sensor with my BNR S3 as reccomnded by everyone, MAF size is stock or whateva the AEM CAI is i didnt upgrade it and it was fine, but if you going to get a new intake may aswell get the 3" for better flow. Go the BNR S3 as the S2 no longer is around get it directly from the states i would recommend. Ull also need to look at an EBC i am using the Cobb EBC, if you dont then u wont hit over 14psi. If your not chasing power could always go for the BNR S1 direct bolt on.

    I don't intend on tuning over 21PSI, that's for sure. The set-up will be BNRS3 + ECUTek Tune. May or may not remove/ install turbo....

    Depends if I'm feeling lucky n anybody wants to lend a hand........I'll provide beers n some authentic Italian cuisine
