OK - I did a forum search and came back with nothing useful - so what's the deal with top mount vs Front mount ICs??
Front mount has to be better for airflow (ie more air temp drop) - but what about increase in turbo lag vs the top mount ICs?? Front mounts have longer tubes and are usually larger than top mounts- so more volume between the compressor and the throttle plates - which means more lag to me - true? I autocross my car - and would like to upgrade the IC - but don't want to induce a bunch of turbo lag (using the stock twins - sequential)
The M2 medium IC looks like a reasonable top mount - any other suggestions?

oh come on....u didnt search...this is the most popular sbject ever.

I would tend to agree that the fmic creates ali8ttle more lag.

Fmic i would think cools better (more direct air flow) but blocks rad which leads to a better chance of having your car run hot. this is prolly a good setup for drag racing

Smic is good alternative. cools good and doesnt block rad....probably a good setup for track guys.

I'd go SMIC for Autox. Probably for a track session as well. IMO, Front mounts are only good for drag racing (which is a great mis-use of the FD) and people that want to just show off.

racer1

firts of all you man stock mount and not top mount like the subarus...etc

Fmic blocks the rad so in track that may be a problem, if you have a bigger rad then is not a big deal. For those that use the car on drag and street racing is fine. Never heat soaks, better cooling etc...

Smic cools enough and does not block the rad. Good for track and auto X etc...

V-mount is the best of all and the more expensive one. Both IC and rad have contact with direct air flow.

Here are a few threads for ya:

Just FYI, we refer to them as SMIC (Stock Mount), not Top Mount which is why your search may have not brought back any decent results.

fastcarfreak

if your into autox and not drag racing, go with the smic.


Section8,
Tell me how drag racing is for people who just want to show off!! dude, obviously your car is not fast or else you wouldnt be saying dumb *** **** like this. You prolly dont even own an FD. please leave your silly comments to yourself. FDs are light weight, have good coefficient of drag, and can make big power. Is this not a formula for a good drag racing car???? I will completely agree that FDs are great handling cars and are well suited for autox and road course, but thats not all they do. BTW, have fun with your tacoma, lol.

damn - SMIC, not TOP mount - and I thought I'd done enough time to not come off like a newbie...

I've been revealed... This V-mount sounds interesting - I'll have to do a search on that. I did find the thread on the SRT-4 IC - which is front mount - but it sounded cheap (and yes all the girls can see the size of your IC)
thx for the threads

Defensive much? If you'd read my post you'd see that I said for drag racing AND people that want to show off. I never said the car wasn't a good drag racer either, I said that it was a waste of the car's capabilities. My statement about showing off was aimed at the kids that street race and only care about what other people think about the way their car looks. From your reaction to my relative mild mannered post, I suspect that you fall into the latter category.

And yes, I don't own an FD yet, I've made that abundantly clear in my previous posts on this board, but I have been on these forums for almost 2 years and I know quite a bit about these cars without ever having owned one.

And my Tacoma is a great, dependable, albeit slow, vehicle that serves well as a DD, and will continue to serve well as a DD once I get my FD.

Get a life man.

Both have there pros and cons.. What you plan to do with the car should determine your decision. On Road Courses, whether you go with a SMIC or FMIC, DUCTING plays a VERY IMPORTANT role.. Make an informed decision and do what will work for you!

SleepR1

I have a GReddy FMIC 2-row. I autocross a few times, and don't drag race much. I don't show off, but do like the FMIC's bling factor. LOVE to open-track my FD.

SleepR1

You don't know crap, until you've owned this thing for at least 8 years, like I have. Just when I think I've experienced every problem there is to experience with this car, there's some new problem that crops up that I have to diagnose. Currently no problems with my car (knock on wood)...

Wow you guys are edgy. Did I say that I knew everything about the cars? I made that statement about my knowledge since
fastcarfreak implied that since I own a Tacoma I know nothing of the RX7, I was by no means stating that I knew everything there was to be known about the car. My statement about the FMIC is based on numerous conversations with close friends that have real world experience with FD's and FMIC's on both road courses (VIR and Summit) and autox - specifically the way that they block airflow to the radiator.

If it's working for you, great I stand corrected, but I personally would not get one, I'd rather have max cooling to the engine than low intake temps.

Thanks for all the personal attacks by the way, you'd think that we'd be able to have a civilized discussion here, but I guess that's not the case.

WVRx7

typical car forum tactics. It's great exercise:

Flying off the handle
Jumping to conclusion
and piling on.

Section8 said nothing at all inflamatory. He stated a true, if unpopular statement, that blocking the radiator inlet with an intercooler is not a good idea.

That little hole in the nosecone is the lifeblood of the FD and those "in the know" rarely choose a FMIC unless many, multiple and varied other measures are taken to otherwise protect the engine.

The FMIC is largely a fashion statement so as to CONFIRM that all the other kids in the mall parking lot know your car is "modded".

Listen to who you desire, but facts and a long history of examples are hard to ignore.

r_ed_line53

...i wanted to comment on this sentence, but waited to see if someone else catches it...

...making comments on something that you don't have is just ludicrous, u have no clue what something is like until you've driven it to the ground, slept in it, made love in it, blow the motor/turbos, basically knowing every little nook and cranny on the car.

one if you bought the FD for only one reason then you bought the car for the wrong reason (great mis-use my butt)... trust me if you had one, you'd be drag racing it more than Auto-xing it, because most of the times you are on the straight-away and i'm not just talking about the track.

two, i didn't buy my Apexi fmic to show it off. mine actually sits way back in my bumper, and if even if it was sticking out - heck ya i'd be showing it off ONLY BECAUSE IT ACTUALLY WORKS.

DON'T MAKE OPINIONS ABOUT SOMETHING YOU DON'T HAVE. Now if you have a Tacoma, fine make all the opinions you want.

that was fun!

WVRx7

I can't belive another attack. If you guys are this touchy about an FMIC then it nearly proves you know it isn't the best option for the car. Overtly justifying and defending an action is a classic trait.

Ok, Redline53, define WORKS when it comes to your FMIC. Do you have emperical data from testing performed by a reputable source that proves that an FMIC performs better or is more efficient than a similarly sized stock mount?

Marketing claims don't count.

And as for people not allowed to have opinions about the FD until they own one, a more ridiculous statement I haven't heard. This guy has been registered here for about 2 years, he has probably done more research and listened to more FACTS and OPINIONS from people than half of the owners. If it wasn't for all the morons that buy one without any data and then ruin the cars, he would have probably found a suitable one and be an owner by now.

It's funny, he typed his opinion in an attempt to further and assist this thread. You provide your opinion and personally attack his credibility and defeame him. What contribution have you made to this thread?

SleepR1

Mostly the FMIC helps make more rwhp than SMIC. I won't argue that FMIC looks better, but, that's not what I'm about. If I were concerned with looks I would have repainted my car before doing substantial power mods.

SleepR1

This statement will draw personal attacks. I think it's rather presumptive of you to "think" you know anything about the FD without having owned/fixed/driven one. And b/c you don't own an FD your opinion doesn't have very much weight regarding your personal preference of SMIC over FMIC...

SleepR1

It's the best option for my car, and have had not any trouble with it. Numbers don't lie, and my setup has pushed 370 rwhp on Rx7 Store's Mustang Dyno @ 16 psi boost from the Japan Spec twins.

WVRx7

Well, Manny, I have never been shown that with any data.

I believe that would be an invalid comparison because nearly all of the people that put watermelon sized turbos on the FD in the quest for absolute horsepower also nearly always use a FMIC.

In my similar 8 years of ownership and discussions with most of the major tuners in the FD world, I have rarely, if ever, heard a suggestion for an FMIC. In fact, the mere act of pressurizing 10 feet of pipe and a core is absurd.

Show me an FMIC owner that paints the core and end tanks flat black and maybe I'll believe it wasn't done to show off. Every one I ever see is polished and usually has some advertisement spray painted on the core just to make sure nobody misses that the cool dude has a huge IC.

SleepR1

Nope. I have the tiny '99 Japan spec Type RS twins with 50-mm wheels (1-mm smaller than US spec twins). The little guys made 16 psi with no problems. The tuner I went with thought FMIC would work fine (Dave Barninger of KDR). I've had my GReddy 2-row going on two years. It looks like hell right now b/c I didn't put any wire mesh in front of the nose opening. I'm definitely not about all show...my car's thoroughly thrashed on the road course at least twice per month during the open track season. Don't tell you have NOT heard about me?...

WVRx7

You have a very well prepared, tuned and presented car. I bet you could duplicate those numbers on a well chosen stock mount ic.

I am shocked that you too can be so cavalier and blatantly dismiss an opinion that you don't agree with. With the volume of moronic questions asked by owners, I would think that the forum would be appreciative of someone that comes here to learn and contribute (and does it without attacking others)

blueskaterboy

we are ********. its just how we fd owners are. after all we do have the best car dont we.

but really man. an FD is for autox. you can use it for drag if you want but its not meant to do that as its main function. if you want to be fast in a straight line just get an old mustang. they are a dime a dozen and can be very very fast.

and contrary to popular fnf/initial d crowd belief, no, you dont HAVE to race when someone revs or challenges you. i've had my car almost a year and i haven't raced ANYONE who has revved at me. not yet anyway car is red and not worth racing something i know i can beat. if a vette or viper or something nice wants to race me i'll give it to them. but most of them around here are old people driven and they dont give a **** about racing.

just wait till section8 gets an FD and mods it to absolutely rape yours in every hole.

dude whenever our mechanic takes the corolla or es300 to checkup or fix and leaves his tacoma, damn, i love that truck. 1st gear sucks but 2nd gear is pretty good.

WV - if i do get 2 row, im going to powdercoat it. i cant stand the idea of something that big being bling colored and visible.
