Is the T25 too small for a FMIC?

First off, I'm sorry if this is a repeat thread. I didn’t see anything on it.

I was looking at a 24X10X3 FMIC on Ebay. Is the stock turbo capable of pushing enough CFM for that?
I’m thinking about getting a Evo 16G, but my financial situation wont allow it for a little while.

Also, what would be better to get first: the FMIC, or the 16G?
 
I would get the turbo first as the stock smic with all hard pipes can support it for a while. You will need other supporting mods for this turbo though (check tuning guide)

But in my opinion the fmic/ T-25 will not give as much bang for your buck as just replacing that tiny turbo with what our cars should have come stock with, 16g

Good Luck
 
contrary to popular beleif I think you should get the fmic first. Yes I said that. I see to many people just bolt on turbos and not the supporting mods and wonder why their car runs like crap. So to answer your question yes the t25 car push enough air for the fmic. I have a big greddy on my car with the stock turbo for the time being and I have no problems what so ever.

Incorrect hardpipes and the stock smic will not support a 16g let alone an e316g. When I had the big28 on my car with hardpipes and the stock sidemount I would get heat soaked so quick it was ridiculous. I would get one pull in one gear on a good night before I could physically feel the car pulling timing becasuse the air going into the engine was so hot.
 
i ran my big 16g on my stock smic and i didnt even have hard upper ic piping..I didnt have any problems. Yes you will gain more power with a fmic and bring ur car to its potential but if you just slapped the turbo on because you couldnt a afford a fmic at the moment, i dont think there will be a problem streetable wise. But if you want more power and and turnin up the boost ur gonna need a fmic. But as i said if you were to run the 16g on stock smic you car shouldnt be affected street wise.

You live in California and the guy asking about the parts lives in Washington. I am sure the normal temp in CA is a lot higher than in WA. The air temp in wahsington is going to be a lot cooler on normal days and as longs as boost is kept to a respectable level (16-17psi), and the car is tuned correctly I see no reason why the car would run bad, knock, or pull timing. I dont know what octane this guy can get in WA but in Indiana we get 93 octane all day long and that combined with no extremely hot days, heat soak and knock aren't that bad on a stock smic.

Get the turbo, just dont push it hard untill you can afford a fmic.
 
I currently have my FMIC on my T-25 with no problems.


It doesn't matter whether you get the turbo or FMIC first just like other said if you get the turbo first watch your tuning.
 
If I were you I'd buy everything before you buy a turbo. I just got my AGP FMIC kit today, 28x10.5x3.5 and yes I still have the t-25. Did I buy it for this turbo? No, of course not. But it's for when I buy one in the near future. But if your expecting huge gains from a front mount on a t-25 I doubt your going to be happy. Just my 3 cents.
 
Just my .02. I ran my T25 on my greddy 24r for a month or so before I got by B16g. It seemed ok and ran fine. The only thing that was weird was on the dyno I'd get a weird spike in my a/f up to ~13:1 around 5k. My thinking is the T25 has a little trouble filling the big front mount and it must fill up completely around 5k and send a ton of air hurdling into the motor. I dunno, just my experience.
 
I'd just like to throw my experience into this discussion in hopes of saving someone from making a mistake that I have already.

I have a 14b and it has trouble filling the 2.25" intercooler pipes and smallish front mount.

more lag and now my system has trouble holding 17 psi up top. It will go to wherever I set it boost wise, but it starts to drop off at about 5700 and by redline its only at 17, no matter how high I set it. As for boost leaks, I only have 2 very small ones. I also have an aftermarket bov so its not leaking there.

I'd think that a t-25 would not even be able to do as well as this.

I think your problem is something different aside from the intercooler, I ran a MONSTER FMIC that I got from a Semi-Truck 36x10.5x2.5 and fabbed up like 200 total , I ran the piping like the 2g greddy IC, very very long, and 2.5'' , and I was able to run and hold 22lbs on a 14b with little to no detonation. And I live in hot ass flordia. It was a bit laggy, but when it hit, it felt good.
 
bit of a knee-jerk reaction, since you don't know my car, but understandable.

no these leaks are very small, noticable only when sprayed with soapy water and at higher pressures.

When I had my sidemount setup with Dave B upper pipe, I had more leaks and larger ones too and it would hold alot more boost. Once with race gas I ran it at 23 psi and it held. I would have held more had I gone that way, but it would knock so I turned it down.
 
I ran a T25 with a GReddy 24r FMIC and I had no problems. I would get the turbo unless to had all the supporting mods first. :thumb:

I wouldn't get any cheap eBay FMIC that I found. Shop around and get something that has a good reputation. :thumb:

Alot of the generic stuff on eBay is cheap for a reason. Cheap Price = Cheap Quality.
 
I got a FMIC before upgrading my turbo and trust me it sure does help a lot.
 
I mentioned before that I'd put the greddy 24r on my T25 well I did and its pretty funny.I feel sorry for the T25 because it sounds like it cant suck enough. Anywas I'd like to say that their is no problems with it, as in I can still use my car just fine. It is just a little bit more laggy and a bit more noisy. What I noticed the most was that It went from about 11 psi to about 10. Other than that its fine no other problems. Just a note for you guys that are thinking about doing it.
