FMIC Options

Just curious what FMIC would be best for my setup.

MOD LIST-
GT3071r turbo, Mazdaspeed CAI, Turbosmart Hydbrid BOV, catless 3" dp/tp, 3" magnaflow CBE, DNP Exhaust Manifold, Grimmspeed EBCS, CP-e fuel pump, Denso Iridum IVT22 spark plugs, COBB AP, Cp-e TIP, Greddy Catch can.

I currently have the PG FMIC, but have heard that the larger piping used with the PG kit results in a power loss.

I've done some research on the different FMIC but would like some input for my specific setup.

Different FMIC's and main factors I have found.

COBB- Well tested and quality hardware. But expensive.
Turbo XS- Looks awesome, no bad reviews. But does the large intercooler cause a PSI loss?
Cpe- Didn't see too much a power gain, just more efficient. Also expensive.
PG- Best bang for your buck, But quality isn't as great, and does larger pipes cause a power loss?

Let me know what you guys think would be best, and other information I should know about any of the FMIC kits. Please keep in mind my mod list when commenting.

Thanks.
 
godspeed type c. buy the cxracing piping without the core then get the godspeed core instead

From what I can tell, the cxracing piping is the same as the PG piping I currently have. The only differences being PG piping is 3" and cxracing is 2.5". And build quality on the cxracing seems to better.

That brings me back to my original post though, what size of piping is the best? 2.5 or 3 and will it even matter with my mods since I have so many breather mods and a bigger turbo?

The godspeed type c intercooler does look significantly better than the one I currently have though. I may look into upgrading that if I don't change my piping kit.
 
OP - I've got the TurboXS kit, and it's badass. It has 2.5" piping (which is fine because most the outlets on turbos are 2.5"), and the core is kickass. I don't have any problems with losing boost. I consistently hit 27-28 psi no problems.

If you just want to change your piping, I'd probably go the custom route. Most likely, it'll be cheaper than buying a brand new kit

It's easy to find couplers that go from 3" to 2.5" to connect to the turbo though, which is what I currently have. If I do get new piping I will be upgrading the intercooler as well, probably even upgrade it even I stick with the piping I have. I don't have the best quality intercooler, it gets heat soak faster than I would like for a Front mount.

I really like the look of the turboXS kit though, not off center and it covers the whole grill opening.

Is there a way to measure boost after the intercooler? If it says you are getting 27-28 you may on be getting like 25-26 by the time it reaches the engine, since the sensor that measures psi are before the intercooler? Not sure but that seems like how it would work to me.

My original point was that you aren't going to lose anything with 2.5" piping.

Also, I'm getting my boost reading from the intake manifold. I don't believe in using the compressor housing to read boost. It's been a long time since my AP has been able to read actual boost, but it seems to match up. I wouldn't worry too much about "boost loss" though. I'd be more concerned about my BATs and spool.
 
Not sure if you get Forge parts for the mazdaspeed over there. The Forge FMIC is getting good feed back over here in the UK.
 
It's not so much the piping, I heard that since the Core on the turboXS kit is so big you lose boost there. But I won't worry about if it's not a problem.

Ya, I have looked up the forge FMIC's, but not sure if they are in the U.S. either. Also I've found some intercoolers with good reviews and specs for about 1/3 the price of forge. Not sure that the extra money I would spend on a Forge would even be worth it.

In my opinion boost loss is like crank hp/vs wheel hp. Sure... Everyone like to say that their Z06 has 500 hp, but in reality it's putting down less than I am at the wheels. HP at the wheels is what counts and boost at the motor is what counts.

FWIW, the turboxs has probably the least length of piping out of any of the other FMIC kits.
 
Do you by chance know the specs on the intercooler on the turboxs kit? I'd like to look around for intercooler options before I decide to purchase it.

I've been trying to find those myself. I'd run outside and take some quick measurements, but I don't feel like taking my bumper off
 
If you do get measurements or happen to find them somewhere post them up please. I'll do the same if I come across them.
 
My 2 pennies...
Your current setup - PG pipings plus IC0035 core (28x7x2.5) is rather good actually. All other setups hves longer routes. COBB and CPE have really long routes, so TXS does also. PG is actually one of the best and smooth routes.
My opinion - you should try getting a little bit bigger cooler for your setup, like Godspeed 31x8x3. But only if you're planning on pushing more. 3071 has cooler boost temps eitherway, and I do know guys with your current fmic setup running 23-25psi on 2871
