Anyone with a MS3 getting a FMIC?

[spek1098]

Any one done/gonna do this this spring?

I thought about it, but I want to see how far a vented top mount will take me. Cheaper overall, plus it looks badass.

You have to be very careful when it come to adding a front mount. You (and myself) are going to have a boost drop and with the turbo already running close to or at peak efficiency. This will be close a 4lb drop across the board. That drop will bring with it less power.

If you are getting a front mount you also need a tune and maybe a turbo upgrade to take full advantage of the kit. I would say save your money and go with an upgraded top mount. You can get that plus a cool hood for less then the price of just the front mount kit.

And this is coming from experience with switching from top mount to front mount with subys.

I would wager that an upgraded TMIC will be sufficient for any MS3 on the stock turbo.

Not to say that going front mount is a bad idea, just that it probably won't be strictly necessary unless you're going big turbo. Or swapping the MS3 motor into a non-speed chassis

 

[mazdamn02]

Ya, I was going to say are we talking ms3 or sp23ms3 here lol.

Or swapping the MS3 motor into a non-speed chassis

Horrible idea. The disi motor is really proving to be weak. THe first guy to go big turbo blew his a few days after getting the turbo on. Rods are breaking putting holes in blocks it's ugly out there. I am sort of regreting my decision to get my ms3. I guess I will keep it close to stock and just do fuel mileage mods to it, I don't want to risk blowing it up with a big turbo.

 

[dmention7]

If you're going big turbo on anything, I'd at least get some decent internals in there.

There's a used True Red 07 MS3 at Luther Mazda that has a new engine and transmission because some idiot was pushing 20psi and blew it up. They put most of the mods he had on it back it looks like too... BOV, CAI, exhaust.

 

[Young Roids]

It just looks like the disi is weaker than other turbo 4s out there like the srt-4 engine and the evo engine. Maybe they will figure out how to tune it and that will fix some of the problems but for now with no tuning it is proving to be rather weak.

 

[spek1098]

Yea, most of you must not be aware of my project, or my history with trying to decide which way to get some more power (trade in, boost n' build, swap). Well the way things worked, I'm doing a swap, inspite the many nay-sayers I've come across. Being my hood is a little less bulgy then the speed, I doubt a TMIC is even an option, and the stock one is toast.

I guess I haven't heard of much loss of power, other then a story or two of the FMIC throwing some ECUs into gimp mode, but I got more digging to do at M3F about that issue. I had planned, at this point, to just go with a FMIC, and see if I had to get the AP, to get it to work right.

That's where my question comes in. All the FMIC kits I've see, incuding Cobb's (which I'm planning on getting), have the piping off the turbo to the IC going over the engine. I'm unsure if clearance is going to be an issue under my Mz3 hood. I'm hoping to see a kit of someone else just to get an idea if I might need some custom piping done.

 

[mndsm]

I'd be willing to bet that the people going big boost are neglecting fuel, and causing HUGE detonation. Gotta remember, tuning is as important as anything. With the DISI being what it is, it doesn't surprise me that people are nuking them left and right. Plus, if I want massive boost, i'll buy a DSM.

 

[mndsm]

There's guys running FI hatches on m3f, I have to imagine the layout of theirs will be similar to what you need. I think it might be easier to adapt an FMIC kit from a turbo kit designed for an NA car, as opposed to a kit designed for the DISI.

 

[dmention7]

I don't see why you'd really need a kit anyways. Find a core that fits, route your piping, call it a day.

It took me an afternoon and $8 worth of PVC pipe to mock up the IC tubing for my car.

So I take it you have a regular 3 and are thinking about a disi swap? If I were going to go with a fmic for the MS3 I would go with the turbo XS one it looks really big and well designed end tanks.

These guys do have the upraged fuel pumps but no real engine management. Hopefully with the cobb ap it might fix some of the problems but who knows. At least I am waiting to mod till after my warranty so I will be able to see if a solution has been made before I mod.

 

[dmention7]

yeah, turbo swap with no engine management is going to result in zoom zoom boom pretty quickly. I wouldn't even consider a turbo upgrade without a ful standalone and custom tuning.

 

[Young Roids]

Well at least have some kind of engine managment I don't know if a stand alone would be neccessary. A good tune on the factory system should help alot.

 

[dmention7]

It would help a lot, but the MS3's ECU is so full of electronic nannies that I would not want to be the first one to try... lol

 

[Jesse MS3GT]

Toms right, the problem is fuel. Our stock fuel pumps cant support the pressure needed when you up the boost. The guys who have blown their engines left and right were running lean as hell. The DISI has forged internals. The problem right now is solving our fuel(CDFP) issue.

 

[Big Nate]

I wonder if the speed6 from 06 has a different setup. Cuz I have gas dripping out of my tailpipe.

There have been so many people that have put so much bad info out there that it is hard to tell what is true and false. All I know is that I have personally have seen A FMIC kit go on a speed 6 (fully stock except the kit) and lose power. So engine management is needed and most likely just ported injectors. And that will help but with a stock turbo I am not sure if you can get a lot more power.

 

[dmention7]

Nate, the speed3 and 6 both run pig rich stock. But when you're making major mods or cranking up the boost without tuning for fuel, all bets are off. Especially since the speed3's fuel system appears to be almost maxed out stock. So, even though they run rich as hell, there is not much wiggle room once you get things leaned out a bit.

I can't really comment on the differences between the speed3 and 6 with regards to a FMIC, except that I haven't heard of people losing power that way on a speed3. With the complexity of the computer control on these cars, I wouldn't entirely expect similar mods to have similar results. But that just underscores the need for a tuning solution before you get much past an intake and exhaust.
