Hello,

It is about that time that I grab a pair of vrsf stock location inlets! With that being said, I'm curious as to what you JB4 users have done to maximize gains from this mod as far as map or custom map 6 tuning goes.

At the same time, I am curious about a rough idea of the power I should be making with the addition of inlets and the current mods in my signature. Currently during 2nd & 3rd gear pulls, I manage 15.5psi tapering to 12 near redline here in MD in the hot months and 17psi tapering to 14 in the colder months.

I then plan to get the 7" FMIC from VRSF late this summer and will then officially dyno at that point- since I don't have any performance mod plans after that point... except for "MAYBE" upgraded turbos or fuel pump but that wouldn't be for a while. Thanks for any info!

I'd do the FMIC before any inlets or outlets.

1) FMIC
2) Charge Pipe
3) Better Airbox or BMS cone filters
4) Inlets
5) Outlets
6) Better Turbos

You could argue to swap 5 for 6, and I wouldn't disagree.

If you are set on VRSF, no issues. They make a good product for a reasonable prices. There are other companies that make comparable products for less $$. If your trying to get the most bang for your buck, you should do more research.

I’ve heard many people recommend FMIC before inlets and it makes sense to really maximize the full benefit of inlets and all over mods as well first.

I'd get the FMIC before summer. Inlets really only shine when you're at the limit of stock inlets and right now with a stock FMIC you have to run significantly less boost pressure and ignition timing. (So you're not so much at the limit of the stock inlets).

You'd have a lot more potential gains with the FMIC and it's a hell of a lot easier to install too.

I'd put the inlets further down the mod list.

Definitely makes the most sense now to slap on an FMIC first. And yeah I’ve heard of the dreaded inlets install as well as how easy an FMIC is to install. My goal is to get the FMIC on in the beginning of June and inlets by the end of June. Gonna be a fun month- finally being able to say I’m FBO + inlets. Cant wait to see the numbers this car puts down on the dyno. Im hoping for 420whp/440wtq.

Stock turbos are already way out of their efficiency range and being oversped at 12psi at redline. They were never designed to flow that much air so you also have high IAT’s, then timing pulls follow...slippery slope.

It always amazes me how folks will spends hundreds & hundreds of dollars changing inlets outlets and everything but the main bottle neck.

Too each their own. Hundreds if not thousands of people have done similar modifications and the stock snails tend to hold up pretty well. As long as you take care of the car with routine & preventative maintenance and aren't driving like youre in a nascar each time you get behind the wheel, things tend to hold up well with the n54.

To really max out the intake system, you'd have to do the following :

1) FMIC - 5" stepped or 7" (to trim and cut or not to cut, that is the question)

2) Charge Pipe

3) Better After Mkt airbox like the AFE Momentum GT or a version of dual cone filters. Hot air vs Cold air debate.

3) Inlets - 1.75 or 2" (2" would be more difficult to install and are only good for after mkt turbos)

4) Outlets - 1.5 or 2" (unless you have a tune and after mkt turbos, you won't see the full potential of outlets). Nonetheless, even with stock turbos you will see a gain in HP & Torque.

5) After Mkt Turbos.

6) a tune like MHD, JB4 or Cobb.

Side note - downpipes will free up 25-30hp, but you NEED a tune in order to avoid CEL codes.
