What are your supporting mods? And you should put your stock scoop back on until you get the FMIC.

A FMIC with the stock turbo will hurt performance. Wait untill you do a turbo swap and then do it. IMO, just pick up and STI TMIC and be done with it.

So .... your top mount isn't getting any air,... All for the looks you think is more important. So now you have 2 air heaters under the hood , the turbo and the IC. I suspect a front mount even with the stock turbo wouldn't be any worse, would be better then your set up now... And it would look even cooler with the front mount.

a front mount intercooler WILL NOT hurt performance at all. most FMICs might be overkill for the stock turbo, though. honestly, i'm pretty sure performance will be improved even more than usual since your TMIC doesn't get any air.

if you think you might upgrade your turbo in the future to something larger than or equal to a 20G or so, get one of the usual FMICs... TXS, Hyperflow, APS, Perrin, etc. if your plans are to stay with a turbo smaller than a 20G, get a small FMIC like the Injen.

or... you could sell your hood and buy an OEM unit.

seriously... why do ppl continue to post crap like this and join in with the conservative nasioc chorus. It won't hurt your performance. Whats hurting your performance and causing heatsoak is your hood. You will get about 200-300rpm more lag with a FMIC. But stock TMIC's get lots of heatsoak easily, and STI TMIC aren't even that great. Why spend $350 on that when you can get the ebay FMIC new for around that price? Right now you should either forget the cool looking reverse scoop and get a WRX/STi hood scoop, or I would get the FMIC and a tune too. Which would add to your "sick" look, minimize FMIC lag, and add performance!

Especially since you have all those other parts including intake and fully catless, definetly get a tune, you'll be very happy you did.

Turbo lag IMO is hurting performance. This is less of an issue with ej25 STIs, but your will see more lag on an ej20. This has been documented on dynos over and over. And most of us are in the north on this thread so heat soak is less of an issue.

There are no "issues" running a FMIC... throttle response does suffer a little due to the longer piping and larger core, but this doesn't equal performance loss. The FMIC makes up for this loss of response with increased flow rates and cooler intake charge, which equals more power. Less heat soak is just an added benefit. Also, I'm in the north (kinda), and heat soak of a TMIC is an issue. Running a Kaminari hood, I really have to wonder about the OP's IAT.

That said, my solution to the problem would be selling the Kaminari hood and replacing it with the stock unit. No money out of pocket is a good thing

While I'm sure dyno plots might show differently, going from a TMIC to a FMIC I can't really feel the difference in lag. And if it's that small of an amount I can't see a reason not to. Granted I have a vf39 and not the TD04.

Have you ever driven a car with a fmic and a stock turbo? Maybe you don't think heat soak is an issue because you've never driven a car without it? I'm not saying that I'd get a fmic if I was him, but imo it wouldn't be the worste thing in the world. He could probably trade that hood for a normal c/f one(or just a normal hood), enough money for a water/alc injection kit, a tune, and possibly have money left over for other stuff. This would probably net more power then a fmic, and cost a lot less(since all ya gotta do is trade in the hood). That's probably what I'd do, but I don't care so much about looks. For some people a reverse hood scoop and a fmic with a stock turbo is the shiz. To each their own I guess.

peace
