Ok guys, im sick of havin hot air to burn with the tiny little stock IC so its time to start lookin pretty serious at a big FMIC. Id sure like some input on the deal though first. Im sure theres info on the forum, but in the last hour i searched i didnt really find what i was lookin for so please bare with another IC post.

Heres what im lookin for. Id like to get a the biggest FMIC i can fit with the stock bumper for now. Eventually i will be gettin a kit for it, but thats down the road when i can get it and have the whole car painted at the same time (which isnt gonna be cheap with chemealion paint). The other thing id like is to be able to fit one big enough to support 750RWHP cuz thats where the cars gonna end up. Im gonna end up makin some of ya mad i know, but its gonna have a 2JZ in it eventually so id like to not have to buy another IC kit when that time comes.

I guess for now my biggest question is which kit to get and how much alteration the car would need. I know several of you guys have different kits so id like to see which ones are the problem kits and which ones went on like a dream and work the best.

Also, id like to get an idea of what kind of hp gains i might look at with a big FMIC instead of the stock one.

Thanks in advance for the input. I know ill have some of the best out there!

 

Upgrade the radiator first.

 

You have to pic a FMIC that is suited for the twins if you go too large you won't get the full benefits.

HP gains? Same as if you WOT your car before heatsoak sets in. The thing is that with the stock IC heats soaks after one run or if you sit at a light... or have your car running for longer than 5 minutes...

 

Right. Seems like by the time i get the thing up to normal temp half the cooling is shot already. Bad placement and size imo... I figured with one right up front all the time it wouldnt get the heat of the engine bay like it does now.

 

Yeah the size is completely inadequate. People with FMIC see intake temps very close to ambient. The drawback is the radiator is blocked from ambient. That is why you must upgrade your radiator and make sure you duct air to it, otherwise you will have H^2O temp issues.

I run a large SMIC (with a single turbo) and I see intake temps of low 30's C on 25C days. Opposed to my friend's FD who has the stocker who sees 60's C on comparable days.

The best of both worlds is a vmount. as you get fresh air to the rad and IC. The draw back is the $$$. But I'm sure you knew that already.


Honestly if you are gonna change up everything under you hood you should just wait and get the right stuff for your new build. Rather than getting stuff now and trying to accomodate your new build to your old parts.

 

just wait until you get the engine swap in order, changing to a FMIC now will just cause water temp issues, which you likely won't have such an issue with the piston engine.

 

Is it easy/possible to run an FMIC or V-mount while keeping the stock AC/PS setup?

 

Well thats not exactly what i wanted to hear, but thanks for the input. I had planned on that to begin with, but when i make one run and things get hot, i cant run like i should for the second one, and thats aggrivating... lol

Another option i had very briefly considered was CO2 spray for the IC. Any thoughts on that until i can get a build? Thatd sure cool stuff off in a rush. I havent looked at kits yet, but it was an option to try and help the stock IC. Input??

 

i find it seriously hard to believe that you found no relevant information by searching. the various fmic/smic/vmount options have been discussed, in length, numerous times over the past decade, and much of that information is still available in the archives.

please take the time to search before starting new threads about subjects that have been discussed to death.

 

^+1

I chose to go V-mount after searching many threads & seeing lots of discussion. Though there is either more fabrication or more cost involved, it is an excellent choice. It seemed the most versatile for hotter climates & easily supported my 400-450whp goals.

My Rotary Extreme Track/Touge setup should be here next week.

 

What no AI?

 

I agree that if you plan on completely changing the engine bay with a different motor you may as well just wait. But if you must replace it now, the GReddy kit should be able to be used with the toyota motor swap. Better than CO2 injection to cool the intercooler would be to add methanol injection to cool the charge temp and this can also be used later for the obvious reasons for using water/meth injection. **edit, looks like supernaut beat me to it..

Slacker, sure it is possible to run both with the FMIC depending on what FMIC you go with. The greddy you can for sure. Vmount, I have seen it done too. Both will require a much smaller battery or a battery relocation though...

 

CO2 spray won't help with the IC to radiator heating issue, you would have to run a constat spray to keep the temps down. typically when you swap to a front mount in rotary applications you see anywhere from a 5 to 15% increase in temps which is substantial when your fan is running 100% of the time to try and keep it down.

 

If you arent going to give some relavent info to our discussion, please just keep your mouth shut. There are people helping and giving good input, and then theres you... A waste of time.

As for the rest of you who have taken the 2 min out of your day to throw in your 2 cents and be useful, i greatly appreciate it. I wanted to hear from the professionals about the pros and cons and your opinions, because they mean more than mine thanks to your experience.

I have looked some CO2 kits, and found one i like just to try and bring the IC back down to a decent temp, but it would be used at non-WOT times (staging, etc.) so i didnt suck up the CO2 and lose performance (i did find a site that did the research and found out what the gains came from both with CO2 and NOS).

Again, thanks for the help guys. I really appreciate ALMOST every one of you and your ideas and recomendations.

 

I know, seriously....We seem to be the only two people who have AI on the brains on this thread......


I would be willing to bet that if you get AI and tune with PFC to say 10 or 12psi, with a fuel pump of course, that you could see really good results, than say running a large FMIC that would increase lag due to larger core and longer larger piping and blocking a lot of airflow to the rad putting more dependency on the rad fans potentially leading them to ultimate failure.

Not much of a theory, i know, but at least is something.
