I am in the process of getting a new IC. Yes I know the debate over SMIC and FMIC. I just wanted to see if it is OK to run a FMIC but still have the car be a daily driver, or do you think I should go with M2's large SMIC. Right now I am leaning towards the Blitz FMIC. Oh and I will be moving down to Florida in about 2 months so I will be putting in a Fluidyne radiator also.
Thanks,

I am running the Blitz front mount with no problems in Southern California, I do have the fans hooked up to a switch and turn them on most of the time to be honest. But even in hot weather (100F) and traffic my temps were still below 90C.. the fans just do more of the work.

Hey bro as long as you upgrade your radiator and do the fan mod you'll be just fine. By the fan mod I mean I have tapped into my fan relays and wired two switches. One for medium fans and if both switches on fans on high. I usually have the fans on medium most of the time at the moment since its summer here in Texas and its been about 95degreesF+ everyday. I have the Apexi GT FMIC with Koyo radiator with the fans on medium my temps never go past 190F even under full throttle boost my temps may go to about 195 but it rapidly drops back down. hope that helps.....Tony

i am assuming that you are worried about overheating your car?

i can tell you this. when are you most likely to overheat your car? yes...in traffic. if you are sitting in traffic, does it make a difference if you something blocking the air flow to your radiator when their is no air flow at 0-1 mph?

have you ever heard about someone overheating and blowing their motor because the FMIC blocked air flow to the radiator? i personally have not. but i have heard about people blowing their motors because of detonation, something that is usually caused by hot air being injested into the engine.

somethin to think about...

I run a greddy FMIC. I have had no problems. I to have done the fan mod and usually watch my gauge to make sure the temp doesn't go to high. Because it is 90+ here in NC I usually just turn them on and leace them on. I see a steady temp of 90C. The only time the temp will rise with the fans off is in stop and go traffic, but with them on the temp will not move. You could also have a PFC that will take care of the fans for you. By the way I have no proof (Dyno), but I can tell you when I put in my Greddy FMIC I got alot better response and the car feels much more powerful than with my PFS smic.


Note: A FMIC is harder to install than a SMIC, that is if you are doing it yourself - but not impossible.

Well I think I'm going to go with the FMIC now, I was worried about overheating with it but not so much anymore. Anyone recomend any FMIC over Blitz's?

I debated this for quite some time and I decided on the Blitz FMIC in part to MJW's advice. I like it so far but I have blown my radiator and I am installing my Fluidyne tomorrow so we'll see how it all goes. I had the Blitz SMIC and it could not hang with my trips down the track so I went FMIC. Good Luck.

Personally, I don't think a FMIC is a problem on the street. On the track (roadrace) that's a different story and even the Japanese tuners have problems with heat and have to pull off to cool down after a few laps. Most run FMIC's of some form or another, with PanSpeed's being a "hybrid" of sorts...All do have issues with heat.

On the street, even the "best" SMIC with a duct offers restrictions to airflow, especially if they're quite large like the . It's just on the backside, not the front. With fans, the radiator should be able to pull enough air through to not cause too much of a problem as the previous respondents have mentioned. On the street, the IC isn't getting as hot with pressurized air as it would on the track so the actual air temp on the IC more than likely, isn't that great.

I was looking at just putting some huge fans on the back of the radiator.

Now I am debating between the street fighter FMIC or the Blitz. Price is a big difference, performance wise is there a big difference. How hard is it to install a streetfighter. Oh and i guess with the streetfighter you dont have to relocate battery that would save $. Unless the Blitz one doesnt require that. Someone help me out, especially if you know anything about either of these FMIC's.

Thanks

The Streetfighter and RX-7 Fashion FMIC's are basically the same and are the easiest to install. You will need to remove the fiberglass bumper reinforcment bar and the metal bar that is welded to the frame behind that. The FMIC bolts where that metal bar was and supports the hood latch. You will also need to trim the bumper a little. Other than that there are no modifications needed, everythign else, the radiator, AC evaporator and condensor, air pump, battery, etc all can stay in their stock locations. They are also the only FMIC's that will work with cold air intakes like the M2. Here are some photo's from my RX-7 Fashion FMIC install - http://jrx7.rx7life.com/fmicpics.htm

To answer the original question of this post, I do not daily drive the car, but I have driven in over an hour of stop and go traffic and my water temps never rose past 89C. This is with the fan mod as written up on Dave Disneys site.

performance wise is the streetfighter better than the blitz? Oh and what did you use to trim the front bumper, a dremel? If the streetfighter is really better I think I will go with that. Anyone have the dimensions of the 2?


Thanks

Personally I think the streetfighter/RX7fashion types of FMIC look funny unless you have an aftermarket/99 bumper. The intercooler just sits so far forward that on a stock US spec bumper it looks weird, awkwardly smashed up to the backside of the bumper opening. Just something to think about, you will be a lot more prone to flying debris/rocks hitting your nice intercooler.

In my opinion a Dremel is the single most important tool needed for a FMIC install. I installed two Greddy FMIC's recently and used the Dremel quite alot. Also with a Greddy you do not need to remove the fiberglass reinforcement just trim it alittle - with a dremel.

From looking at the 2 I'd say the Streetfighter is noticeably larger than the Blitz. I used a sheetrock/carpet razor to trim the bumper, sliced right through it like butter.

I agree that it is a bit strange looking, but further forward means less heat soak and better cooling. I'm looking into aftermarket front ends now. Debris is always a concern regardless of what FMIC you get.


The Dremel is a great tool, but not for an RX-7 Fashion or Streetfighter FMIC install. The fiberglass reinforment must be removed, there is no way it's fitting in there with this IC. Also the metal bar behind the rebar isn't coming off with a Dremel, you need to drill out the spot welds and then chisel or pry it off.

Well after much thought I am going to go with the Blitz. Now if someone would just hook me up with a deal Jason feel free to jump in and give me a nice low price I know there expensive so I'll be resonable.

Daily driven with HKS Type S FMIC, Koyo radiator, and PFC set to turn fans on earlier. I daily drove the car avg 80 miles a day in Southen Cali traffic.

Silex

Regarding either setups, do they work for single turbo applications?

SleepR1

Do any of FMIC owners road race their FDs?

I'm confused about which IC to get...

Check out my photo gallery here

I daily drive my FD with a custom FMIC. No problems at all.

I do track events and autocrosses with mine, SleepR1. In the heat of the summer, I had to back off after a few hot laps after my water temps rose to 105 and didn't appear to be slowing down. As soon as I stayed off the boost a lap they dropped again. However, I have absolutely NO ducting yet, so that should alleviate the problem.

And I vouch for everyoen else that says it doesn't cause trouble on the street. Definitely true. Like others, I set my fans to come on at 92, so it's very rare that my water temps rise above that.

SleepR1

tailhappy,

twin or single turbo?

how much boost?

what ducting are you referring to?

is your radiator mounted vertically?

are you using the Koyo (I have this on order)?

we need details
