[ShortShift]

Trueform Technology.
install was done when doing new stock turbos.
they are holding up perfectly, just need to clean filters after 12k.
They have transformed my car, i have a few friends with e9x m3s some dct some 6mt, they all used to pull on me by a 1-3 cars depending on mods and how i shift, with the inlets i pull 3-5 cars on them and that was with a slipping clutch.

car is fbo and 91 oct, NO E85 OR METH!

If you think that isn't going to "work" the turbo more, I don't know what to say. It's well outside its efficiency range. I don't think anyone should be shooting for 500 whp on stock turbos + inlets and think it'll last, there's a reason why only 1 car has done it

Hypothetically mmp could have ran 40 psi and I doubt the end # would be drastically different than the 508 on 3x psi

You are mistaken Dave. It was 25 psi taper to 21 psi at 75-80 WGDC. There are many running 21psi taper to 17psi running 100% WGDC therefore running the turbos ALOT harder. My turbos were ran that way for almost a year. I thought they might smoke or blow but they didn't and when I removed them they were perfectly fine, no excessively shaft play and were not smoking, not even WG rattle and they were the original turbos before WG recall revision. Some will say I had "freak" turbos but there is another person in Houston who set the stock turbo 1/4 record recently at 11.1 sec and also fastest quarter at 126mph using MMP inlets under same tuning conditions I had mine and his turbos are working perfectly fine also. It a function of e85 and proper fueling and tuning and supporting mods. He made 495whp on the dyno.

Ok, so vargas has inlets in the stock location that use a dci. $410 plus options. Not quite as good flowing as the others.
Vrsf has $269 aluminum inlets with fair brackets that put the inlets on the passenger side for bigger tube. His go from 2.5" and taper to 2' it requires relocating a few things to fit.
Mmp is similar to vargas in price and fit but runs 2.5" tubing all the way to the 2" connection.
Precision raceworks is Mmp style but upgrades materiaks, looks sharper, and costs $500
And tft is the $1500 option that uses best materials and replaces a few things but is basically similar to an Mmp setup.

Going gradually or abruptly from 2.5 to 2" is debated as being a positive or negative for flow.
Stock is a restrictive 1" plastic inlet.

Did I miss anything?

Damn that 91 octane hurts i pull on m3's just with a cobb or jb4.

Again some mis information here, MMP inlets are $269

For those that want to see the 500whp stock turbo dyno with MMP inlets record that has not been broken yet, see here

*NEW* Stock Turbo World Record, 500rwhp 540rwtq!!! http://www.e90post.com/forums/showthread.php?t=1110928

It has the logs and dyno posted as well as supporting mods. It shows 25psi taper to 21psi.

30psi or 40psi is all BS, was not done on the dyno run.

[Fundguy1]

The thing I would really like to see is a flow comparison of the above options. If there is one, can someone show me? If there isnt, can one of the makers who's confident in their product do one to show us the results?

At the moment for me it's between Mmp and Vrsf. I don't care if it looks like dogmatic. I just want the power. I have 225,000 miles on my car. It won't be a show car for looks, just for ass kicking.

You missed RB, if that matters?

Think a lot of you guys are getting way to hung up on "flow" on these things, much as if they are going to "supercharge" your turbos if they flow better. It is true that you need a good flowing pipe, but getting to the level of discussing disparity in flow of any of the options is like discussing which is $25 more or $25 less in cost.

In short: They all are going to add a ton of power… make your decisions based on which you like all around (installation, fitment, cost, appearance, material, branding, resale potential, etc, etc).

Here is the flow testing done on MMP inlets

MMP inlet flow testing - 4x and 2.8x better than stock inlets!!! http://www.e90post.com/forums/showthread.php?t=1126801

Sooo....MMP it is lol I'll be placing my order soon!

MMP is great. Installed mine last night and it works perfectly and the customer service is second to none

[Tiago@VRSF]

These just arrived back in stock and we had another 40 or so sets go out today with a few of those being RB and VTT guys looking to break some records. Our FMIC currently holds a few records on this platform, I'm sure the next few weeks will be interesting for inlet records

[Grand_hustle17]

Mine went out today and will be here saturday 😁... Went vsrf.. Was vsrf or mmp.. Seem both had complaints on brackets and other things. Vsrf said its been revised so i went that route. At 1st i wanted mmp due to bigger piping but it seem for stock turbo the rears are bit more a pain i guess.. Either way two good companies n i chose one over the other

[Shadow007]

Does it matter if I get either the 2" or 2.5" version with VTT stage 2s? I keep seeing 1.75" for oem or RB turbos or 2" for VTT 2+ or Super RB etc.

That's referring to the snouts on the turbo.

If you have mmp or vrsf or tft that's just a matter of having the correct sized coupler

[Fundguy1]

I'm not doing the install so easy install doesn't matter. I'm still back and forth between vrsf and mmp. Same price, similar quality. No power difference? I'm going for 675 rwhp/rwtq.

[Grand_hustle17]

Im not doing the install neither but i kind of leaned towards vsrf only because it seem to be the right fitting for oem turbos and if i go hexon... Honestly i love how precisions sit in the bay most

Robert/ PR makes a nice kit- I think they have some deals going on in regards to pricing

How far along is your build? I figured you'd be about done with everything by now

So being that the RB and VTT stage 2s are both hybrid turbos are damn near identical would I have to get the oem 1.75" version? But according to the MMP website, he was using the 2.5" on stock frames...kinda confused on which version to order?

1.75 or 2.0 would work on the Vtt 2 or RB next gen

If you go with the RB stealth (my recommendation) you will need the 2.0

Just something to remember- mmp, tft, pr all require a good amount of relocation aka more labor = more install cost

The RB inlet and Vtt allow you to utilize stock / oem placement and would probably save you a an hour or 2 or 3 in labor depending on the skill level of the installer/shop. May be an easy way to save a few pennies if you are on a budget.

Chassis and brakes are done. I was out of work and had to make up some bills. Now I'm good. Want to be done by Xmas. Only need turbos, clutch, inlets, fuel rail, lpfp, cobb, charge pipe, downpipes, and diverters left.

Here's the build thread.
