HS 1.6L turbo kit ? - why no CAI?

dono200sx · Jun 22nd, 2003, 11:26 AM

I haven't seen any threads on this as of yet, so I'm hoping I'm not starting a new thread on this.

I've been noticing that in most pics of turbo kits that I have seen, the GA16DE turbo kits specifically, I always see the air filter under the hood.

It just seems to me that it would be more power efficient to have filter down behind the fender, CAI style. It seems to me that all that would have to be done is relocate the battery to the trunk (I'm already planing on that) and then custom building the piping to run down to the fenderwell. It seems to me that we might be able to squeeze an extra few ponies this way, but I never see it done. I am by no means a turbo guru, I hardly know much about them, but one would think that cooler/denser air (not to mention MORE air) in addition to the turbo would be great. Maybe there is something I'm not thinking of.

Can someone explain this to me? I've been thinking about the HS turbo kit for my 1.6 and this was something I was considering doing. I already want to relocate the battery, so that isn't something I am going to worry about a whole lot. I want those few pounds it adds to the front end gone.

now i dont have a turbo.. but i would believe that you could make a cai cuz the colder the air the better your car reacts to it.. i know cai are better than short ram so i would think that making a cai for the turbo would be better.. but i could be wrong

you see... it would make sense wouldn't it. I wonder if HS has done any testing on this?

i dont know much about turbos or anything, but i think that a CAI would interfere with the FMIC piping....i really dont know, thats my only explanation

That is one thing I was thinking could be a problem. Though the area inside the fenderwell is pretty big. Maybe it can be re-routed, maybe it can't. I guess I may not find out until (if) I turbo the car. (Also considering S13/SR20DET project thatI am leaning towards) Maybe someone who has done a turbo B14 will know for sure.

isn't having a CAI with a FMIC like bringing sand to the beach?

holy200sx · Jun 22nd, 2003, 01:58 PM

well.. consider the FMIC a cold air intake maker..

I have CAI and FMIC... it just makes the air colder than what the IC can make it...

Katana200sx · Jun 22nd, 2003, 03:53 PM

with a turbo it doesnt seem the cai would make a bit of difference. just bc the turbo will beat up the air and heat it up anyway. instead of making a cai i would just get a nitrous express n-tercooler kit.

James · Jun 22nd, 2003, 04:09 PM

it does help because the turbo heats the air up a certain amount higher than ambient air temperature. meaning if air coming in is 75 deg. it'll be like 100 after compressed and if it's 140 coming in then it'll be 165 after compressed...

James, did you notice any more power with the CAI/FMIC combo vs. just a FMIC? Difference in driving characteristics? I'm just trying to see if there is any more power to be had for future reference for a project I want to do.

apparently, from people ive talked to, Hotshot was supposed to change the piping design to make it a cold air setup. ill see soon though

in about 2 weeks.

u will make more power if u start off with "cooler" air.....it is definitely possible to use a CAI setup

dunno, I started out want to do the CAI so I always had the filter in the bay... even when I was running non IC... there was definetly a power increase, or more or less recovery, from using a FMIC... power is more stable and doesn't drop off as the air gets hot...

Javier I've been meaning to ask you... I used 2.5" pipe after the IC to help with the pressure drop through the IC. Do you think it helps or would it be more beneficial to use 2"?
