i have a vf39 on a 2.0 with this fmic.. the lag is barely noticeable.. 3500 goes all boost, it cools off the air a lot more.. u can feel by touching teh cold side of the piping.. my sti tmic was always hot.. i do notice running a bit lean cuz of the cold but still safe.. i was hitting 10.2 a/f at red line.. now i hit 10.9... i need a better tune to lean it out a bit more.. and get some horses out..

A lot. I hit peak torque 200-300 RPMs faster with an STI topmount thank with this Ebay FMIC.

just my 2 cents tho
and if u do think there is a lot of lag start doing some PnP work
u can get the tb, intake mani, header, tgvs done for about 380 off this forum
P'n'P work is overrated. Spending several hundred dollars on porting work to make up for an inefficient FMIC system is just silly. Don't forget that a FMIC has no real benefit on a stock turbo'ed car. If you drag race and spend a lot of time sitting in the staging lanes, then buy an ice machine.

Do not do it. If a VF-39 gets laggy, an TD04 will be lag city.

Well said. The STI topmount is a good setup. It actually cools fairly well, and will not be nearly as laggy. Keep in mind that tube and fin intercoolers may lose boost pressure, but this is because they cool better than bar and plate intercoolers.

Great advice Would you care to back that up with data, or at least a catchy story?

Were you even tuned in the first place?!? I think it is much more likely that your AFR leaning is because of a change in IC design than cooling ability.

At this point, I will ask a question. Has anyone actually monitored the IAT (Intake Air Temp) after the stock intercooler, and compared it to the IAT after the Ebay FMIC? I highly doubt it.

Having said this, feeling the intercooler or the cold side pipe means almost nothing. I would rather have an efficient intercooler absorbing the heat from the air passing through it, than an intercooler that stays cool to the touch and traps hot air inside the motor.

This is what I call efficiency.

Are you seriously that against having a front-mount that you felt it was necessary to write all of that.

Although personally I would stay Top-Mount unless I had a 20g or bigger. Depends on your application though.

I really need to get a new BOV setup. Mine is leaking and surging and its just bad news all over the place. Im not sure if I should just get a Tial welded on or get a TurboXS and hope it doesnt leak.

TMIC = Heat soak (any questions?)

All turbochargers have certain amount of lag. Most of those that complain about lag usually are accustomed to running tiny turbos. The minute amount of lag one may feel from a FMIC is a small price to pay for all the performance gains.

A Forge Fully Recirc. with the TurboXS Adaptor but its leaking and im getting occasional compressor surge. I want to get this sorted out before I get a re-tune. I'm thinking about ordering a TurboXS Hybrid BOV.

I definitely want to order something by the end of the day, I just need some advice. Can anyone chime in that's using a front-mount type BOV.


EDIT: Ordered the TurboXS Hybrid BOV. I hope this helps.

you're sure its compressor surge and not just gaseous cavitation like with most front mounts?

200-300 RPMs of lag for a gain of -10 WHP/-15 WTQ is what I experienced. What were your performance "gains"? If you do not believe me about this kit's lack of efficiency, get the opinions of a few good tuners.

If that is acceptable to you for a small turbo setup, then by all means, go for it. Just do it for the right reasons, and not for the look. If you don't care about performance, then you are probably not reading this lol.

Also, if you do go with this kit, get a blow-thru MAF and a GOOD custom tune, not some crappy Off the Shelf map. This way the intake choice does not matter, and you can run a simple intake tube with a filter.

It is not that I am against Front Mounts, it is just that it makes me laugh when a lot of these people are asking about using them for stock turbos. I have experienced it, and the car was not nearly as fun to drive. If you are going to have a stock turbo, then you might as well enjoy the benefits. If you want power and do not mind turbo lag, then get a bigger turbo.

If you look around, there are guys running TMIC with Meth that have almost the same WHP as a comparable FMIC setup, but with far less lag and more Torque.

You know what they say: HP wins arguments, and Torque wins races

True or not, I don't like the idea of water, meth, or water and meth injection unless you have an ecu/standalone that has the abilty to switch fuel, timing, and boost maps if an error in the injection system occurs. So because of this I get my power and cooling by switching to a fmic rather then running a tmic with injection.

I believe in a true pump map and a race fuel map. I don't need to stress my car all the time running essentially a race fuel map every day. If you want the additional power on pump, get a bigger turbo. If you only want the additional power during a race then drain your tank and fill it with race fuel and switch maps.

but it was an easy fix, just losen up the bolts that support it and move it over until its centered.

I can see why you would be concerned . Still, there are lots of people running meth but try and find a "my meth kit blew my motor thread". You may find a few but I haven't. Also if one does not cheap out on the kit they choose fail safes are included. The HFS-5 is very good at this as is the Perrin PW1.

Anyhoo this thread is supposed to be about a particular fmic kit and the ins and outs of installing and obtaining it. So I will take my TXS tmic and soon to be installed Perrin PW1 and be on my way.

My .2 cents first. Without meth injection I would rather run this fmic than a lot of tmic's out there. That would be if if I were running a turbo sized 18G or less.

I ran it with a 30r with no problems.

Is it the most efficient intercooler on the market? Hell no.

but it WILL cool the intake charge. I switched to a far better fmic now.

didnt mean to bump this thread but im surprised so many people are still bumping for questions that have already been answered. for those that claim they dont want to read you can search for specific word combinations in a specific thread. try that when your stuck on something first.
