Hi Everyone!

Does anyone know how good the stock intercooler from a 4AGZE is when being setup in an AE86?

Or should a different intercooler be used instead for better performance? If so, any recommendations plz?

probably not that good if your still leaving it as a top mount unless u wanna hack into your bonnet but if u put it as a front mount it night still be alright... i dont think many people bother though cause u need custom piping etc...

Yeah I do want to set it up as a front mount...

Performane wise there is not that much of a difference between running stock top mount and a front mount although inlet side pipes stay cooler . ...but for $150 or whatever you can get the one's from just jap ect .

as far as an intercooler goes, that aren't at all effective.

inlet temp are pretty high, whether front mount or top mount.

you would need custom pipes to set up a front mont, for the sake of a 100 bucks grab a bigger better flowing cooler

Okay cool... Now I have an idea what kind of setup...

So what about the size of the intercooler?

Would size affect the performance?

what forced induction set up have u got and how much HP will it need to be flowing?

dont go to big for a 4agze, you wont need too bigger core size to drop your inlet temperatures down to 5-10deg above outside temperature.
I run a 450x300x100, thats a little overkill, u could easily use a 350x300x75 and it would work just as well, you could probably go smaller than that still.
Your performance will be affected by the lengths of your piping, keep it as short as possible to help with response and your idle hunting.

Theres a heap of info on 4agze Intercooler setups on this site, just do a search, you should find pictures of other peoples setups as well.

And yeh the cheapo coolers will work as well as the more expensive brand name coolers. I wouldnt bother getting an expensive one.

Iam running a trust cooler on the front and my car has made 150.9hp at wheeels...
the coler was second hand and it cost me 200 about two 18 months ago
It measures about 280 x 450 x 75 (I Think ) and it fits just right...
look for evo 4 cooler as they work find

i'd go for an evo core.. i was going to use one... then i just whipped one up using a PWR core http://www.ae86drivingclub.com.au/forums/emoticons/rolleyes.gif jokes.. my mate did.. 240x400x75... made 145rwhp on stock boost.. but it was tube and fin, not bar and plate..

So how much did your intercooler and piping setup cost?

Any particular brand recommended? PWR? Hybrid? etc...

stainless mandril piping, and a custom PWR core, with fabricated end tanks, all silicone/clamps etc.. fitted to the vehicle was approx $1200 but this was years ago.. and PWR's price can vary from core to core..

Anybody else got their intercooler done for a 4AGZE?

Just Jap have a 450x300x76 for $169. Im going that if i can't find a evo/vr4 one.

which intercooler are you saying is not effective? and so which intercooler is then?

what's the inlet temp you got on front mount ..and/or top mount?

i use a supra intercooler its about 350x300 and the pipes both come out the same side which makes it sweet on the gz setup and they are realy short which is good. ill sell it cos im going turbo pm me if interested?

If your doin it on a budget u can do it quite cheap using a bar and plate, steel piping and diy or an exhaust shop to do the welding. Can still look ok just use metal putty and paint it.

I'm gonna probably get a 400x300x73 (2.5" outlet)...
I'm assuming it's gonna fit with no problems with the standard front bar right?!

DavisJD
2nd September 2006, 02:25 PM
yeh ul have no problems making that fit, u may have take the air con compressor stuff out, (not sure what its all called, sits in front of your radiator)

But then again, it may fit with it in there, but who needs AC! Power robbing fiend!

im running a 450x300x75mm item, 2.5" mandrel bent alloy piping, i haven't had it back on the dyno yet (back on tomorrow). my inlet temps are around 24deg, as were my evo7 cooler temps were around 35deg. i made 140odd rwhp at 4000rpm (then blew head gasket).

Will there be idling or other issues using an intercooler of that size? 400x300x73 that is...

DavisJD
29th September 2006, 07:35 PM
the length of your piping will have more of an effect on idle than your cooler size.

Bud id expect to have idle problems on any front mount setup on a GZE.

if u dont, your lucky.

When you guys say idleing probs do you mean it idle's a bit low or stops sometimes.
Check out this front mount but its on a ae82.

What if I don't use an intercooler? How will that affect the performance of a standard GZE setup?

i was thinking about running no ic try it and c how much power made? maybe the pipe length will will be more effective than the heat reduced by the ic!

DavisJD

you will loose alot of power buy not running an IC in my opinion, and it was proven in my car.

I went without an IC for just under a month and my intake temperatures were between 60-90degC. with my IC there between 15-30degC.

I had both setups dyno'd. The setup without the IC was detuned to protect the engine and it made about 80rwkw.

With the IC it is safely tuned to 125rwkw.

The idle problem you'll get is called 'hunting idle'
the revs will jump up and down and not sit steadily, and if its really bad, it will stall when the revs drop down.

Its nothing you cant put up with, but its not perfect.

Will there be any unexpected acceleration/revving problems? Continuous revving even after acceleration?

How about an intercooler with the outlets on one side only?

Hi DavisJD,

What was the throttle response like without IC vs with IC? Also when you stab the throttle at idle is there a delay before tacho response?( with IC installed) What boost and gear did you use to get 125rwkw?

Thanks

hi guys,

was going to start a new thread but thought my question may be relevant in this one. hope you dont mind th e hijacking..

i just finished all the piping for my frontmount for the GZE, and i have found that the vacuum under idle makes my 90 degree silicone bends collapse, they are good quality 4 ply silicone hoses but still collapse under the vacuum.

i realise everything will be fine when under boost but i dont like it as the hose may deform over time or something.

has anyone else had this happen? just leave it be or try fix it?
i was thinking if i bent up a coat hanger or similar into a coil and stuffed that in there it may help. but not sure

Thanks

You'll actually have to use hoses that have some sort of reinforced metal... Otherwise, like you said it'll collapse... Or actually use steel piping... This was something my mechanic pointed out...

There shouldnt be problems with revving after u let go of the accelarator.

In my car there is sometimes a slight delay when u stab the accelarator at idle.

But in an older tune (with IC) there wasnt. However my current ECU tune (i had to replace my ECU) was a rushed one so there is some flaws like what your talking about, but they can be ironed out with a little bit of patience.

Not sure what gear that run was in on the dyno, but was running 9psi to get that figure

The silicon bends 'sucking' in is normal with the GZE. U can either reinforce the silicon, or use all metal bends. But it wont be a problem with a little bit of bending on the silicon. Just check every now and again there not coming loose.

Bassically your GZE with front mount setup can be perfect, u just need to spend some time getting the tune just right.

If your using the factory computer, change the throttle body for a larger one as shown here

http://www.ae86drivingclub.com.au/forum/in...?showtopic=2591 (http://www.ae86drivingclub.com.au/forum/index.php?showtopic=2591)

And deffinetly dont run no IC. Bad idea!

Sprintah - Given where the ZE thottle body sits (start of the intake) the whole inlet tract sees full vacuum. So anything flexible will be sucked in. Use metal bends and SHORT silicone or rubber joiners where needed.

Frontmount ICs are good. Throttle response and idle are affected but you can easily live with it. Just don't go silly with size.
