Anyone tried this on a FC?
any pics?
does it make much difference to a FMIC?
What do you do with the radiator?

Horizontal like how there were installed in the TIIs? The vent in the hood was to let ram air come in and cool the intercooler.

horizontal like this (Panspeed FD)

Damn....there is hardly enough space in there as it is. Mabye drop the radiator a few inches and install like a Starion intercooler, and mabye it would work.


But why waste you time? A FMIC is super efficient and there are several headache free bolt in options for you out there.

I agree with rico. It might be easier to do the horizontal thing, but if your going to do it at all, do the best way that you can. FMIC is much better.

Starting to sound like it

on another note. is it just me or do hardly any rotary owners make cold air boxes for their intakes. most ppl seem to just slap the filter onto the turbo

rico05

Cold air boxes are so easy to make...I just never got around to doing it....

dr0x

A lot of people dont make cold air boxes because they are lazy. Having a little box there isnt going to do much unless there is a vent for fresh cool air, which a lot dont have. Either do it right and make a cold air intake or dont do it imo.

Yes, I am finishing up my Horizontal mount IC very shortly.

The advantages of Horizontal over FMIC are full airflow to oil cooler and radiator and very short direct intercooler piping. This really helps on the racing circuit where engine reliability and throttle response are very important. For drag racing FMIC is better as IC will recieve the highest pressure/coldest air and overheating and throttle response aren't and issue.

Oh god no! It is so much harder to do the Horizontal mount IC. Everything has to be relocated and custom made to make room for a decent sized core. FMIC is obviously not better for all applications- that is why Japanese road racers do the Horizontal mount.

There may be advantages to running the filter directly on the turbo. The filter (especially one w/ built in velocity stack) right on the turbo can really cut down on turbulence of incomming air and that means more air ingested. If the vehicle is constantly in motion and or cold air is piped up to the filter the heat factor is lessened. It really depends on vehicle and application whether the ultimate flow or where the air comes from is most important.
Check out all almost all the Japanese race RX-7s- they have the filter or velocity stack and screen directly on the turbo inlet.

My set-up includes-
-oil cooler relocated to front of nose (looks like FMIC...)
-a 26"x19"x2.5" radiator and Blackmagic fan w/ top moved back 10.5" from stock location
-19.5"x8.5"x2" NPR IC core w/ 2.5" inlet and 2.75" oultet
-12" long turbo to IC pipe w/ one 90 deg bend (length measured along outside radius of pipe)
-9" long IC to TB elbow pipe w/ one 15 deg bend
-full stock airflow to oil cooler/radiator
-seperate cold air duct for IC from nose of car

It looks much like that Panspeed set-up (my inspiration after I saw it lay waste to NSXs and a 900hp Skyline in Option vid #92). I'll post pics maybe next week when I cut out all the CF for the shrouds- it is getting close to done :-).

Man, please post those pictures! Looking foward to them.

I just started working on a v-mount setup for my 2nd gen but I have so many other projects that it will take a while to complete. I've only just cleared out the front of the car of everything that has to be relocated/fabricated. I have a couple of more immediate projects to finish first so it may be a couple of months until I get mine together. I'd love to see pics of yours though.

A horizontal mount intercooler modification is very popular in japan. I have about a dozen pics on my "rotary collection cd" but I cant' get it till tomorrow. I'll try to post a couple.

As said before, the main reason for a HMIC is so you don't block air flow to the radiator, and also your IC piping is lots shorter, so it helps combat lag.

Won't the v-mount really only work if you have a reverse hood scoop? I don't see where all the air flow for the top unit would go without one. Every car I've seen with a setup like that as a hood like that.

rico05

Well, I was trying to say that yes: a HMIC is a GREAT upgrade and is full of merit, but is costly and a LOT of work (as you have pointed out). A FMIC is just fine for the casual street application. I am really wanting to see some pics of your HMIC when you get some!!!!

Well, where does the air exiting the oil cooler go? Where does the air exiting the radiator go?
Where does the air exiting the stock IC go?
Where does the air exiting an FMIC go?

They all exit out the transmission tunnel in the firewall.

A Horizontal mount system is OPTIMAL when using a reverse scoop above it in the hood because this is in a low pressure area and draws air out very well. There are several inches between the IC and the hood though, so it could have its air exit out the trans tunnel like everything else.

For my system I am using an aluminum NA hood w/ carbon fiber reverse scoop. Speaking of my project, damn- I just recieved my silicone radiator and IC couplings and I mis-ordered some sizes. Might be a while longer before pics. I should just clam up untill it is done, but it is so tempting to respond in the meantime...

Thats what I'm talking about. The radiator and oil cooler are already aligned in a direction that will cause the air to exit at the tunnel. With the intercooler in a horizontal position I would think you'd get bad airflow going through that cooler. To be more useful, I'd make it much more of a >. So is that what you're looking to do or more of a 7 type of shape?

Here is a picture of the HMIC kit available for the FD3S from Shane Racing www.srmotorsports.com

I can't get my CD drive to read my CD! I have about 10 pictures of Japanese FC3S's with HMICs.
