Default Inlets !!!Need help between relocated or oem.location inlets - 10-24-2016, 12:52 PM

Hi i have an n54 fbo meth and stage 2 pure turbos am willing to buy inlets but am lost between the relocated mmp and the 2" oem location from vrsf or mmp plz help me decide am looking for the inlets that will give me the best performance gains my local tuner told me that mmp relocated inlets will not fit into my pure stage 2 turbos because there are 2.5" in diameter vrsf and mmp oem location 2" will fit*

1_What do u think abt this i doubt because am gonna buy the relocated ones from another tuner
Advantages disadvantages
2_ am willing to upgrade my lpfp to aem e85 compatible what ur expertise say abt it ? Is it good, i have a 335 09 n54 does it replace the 2 oem lpfp am totally lost of how am gonna install it .

3_does inlets and lpfp requires any backend flash or just i install them and drive i already have e85 hybrid back end by mhd*

4_last quest sorry but ur the expert my local tuner told me that a custom back end is way faster then bms hybrid e85 by mhd , is this true ? Can a custom backend *be faster then the most aggressive backend i dont just need fast i need safe and fast , i will never change to any stand alone *flash like mhd or whatever jb4 is much safer i know how much effort bms putted to created that magnificent piece of art , thank u for all the support bms and jb4 fan.plz help me decide and what u recommend am already 500whp without inlets or lpfp on stock tmap am wlling to hit 25 psi after i change my tmap sensor and adaptor will i hit 550whp after all the upgrades ?

1) I like passenger side inlets. It also allows for a custom IM, cleaner engine bay, more room for meth lines/bungs, etc. Might as well get an outlet pipe too and let both sides breath. I like my MMP inlets and outlets.

2) Just buy a LPFP kit from FuelIt or BoostConcepts depending on your goals.

3) I would get a custom flash made for your car. It's small money and will net more than an OTS flash map.

4) Get a 3.5 or 4 bar map sensor. If you like JB4 buy it. MHD is a decent app as well.

Thnx man for the support, but passenger inlets are too close to the turbos and exhaust what abt heat soak ? Am on fbo jb4 g5 iso pure stage 2 ,e85 hybrid by mhd backend and what about aem lpfp e85 compatible is it a gd choice ?the custom flash will be faster then e85 hybrid by mhd ? What about timing ?

Mass of air being pulled in negates heat soak.

Passenger side will get you more power. I had that on my stockers and made 500whp. Sounds pretty cool too.

If you do go passenger side go RBs. The fitment is spot on. I tried other brand and trust me RBs are the way to go.

Am confused between mmp passenger relocated inlets and vrsf silicone inlets 2" , 2.5 " the relocated has more flow but it sits on the hot side of the engine , and i've heard that its too close to the turbos and gets the turbos to overspin and be damaged i donno if its a rumor but i will not take the risk , maybe bmw made this long inlets for a reason...

No, it will not cause your turbos to over spin. That makes no sense. You control how much boost you run. In fact its better for your turbos because it helps them not work as hard. Think about this, the inlets are like a straw for your turbo, the smaller diameter and farther it needs to draw the air from the harder it is working.
The only reason to go stock location inlets is for looks imo. If you want more power the relocated ones are the way to go.
