Default Picking the right intercooler for the job 2002 WRX

I have a 2002 WRX. My head is spinning with the intercooler options.
I would like a TMIC simply because they are cheaper and they retain the stock look and the "function" of the impreza...but im open to a WELL made front mount. quality really matters to me.

i have a vf30, sti injectors, walbro pump and utec.

here is the car


My options are:
ARC TMIC, ARC FMIC (well made)
HKS TMIC
PERRIN TMIC
HELIX TMIC ( I heard the helix is nice)

does anyone have experience with the HKS unit?

I am also looking at a hyperflow FMIC since it fits miles better than the new turboXS unit which seems to be a little on the crappy side.
I wish that they still made the APS DR500, since that would fit my stock look perfectly.

I hear good things about the hyperflow v2 and Helix. I just had Speed Factor's new 20"x7.5"x4.5" TMIC installed and so far have been pleased, but need to install a new splitter (the stock one... doesn't quite fit) before I can form an opinion on its efficiency over long highway pulls, quarter mile runs, etc. It is really big, and my installer had some trouble with getting the stock bypass valve to seal probably, but it did seal. Pressure drop stats are great, I have some rubbing of an AC line but have solved that for now with reinforcement hose on the AC line. The price was nice, $650 IIRC.

thanks but I'm not a n00b.
I'm mostly interested to hear data on the ARC unit since it is a tube and fin upgrade.

My links explains everything you need to know. Heat soak is the same for EVERY intercooler. Dyno charts are useless with intercoolers as it depends on the tuner. Bottom line is if you want to be a JDM dude, buy either. If not, buy something cheaper that best fits your turbo.

the thing is that I have noticed heat soak is NOT the same for EVERY intercooler.

my old hyperflow was noticeably worse (albeit with the stock spliter) than the stock unit.

I was unable to go to WOT in the texas summer after about 30 minutes of driving without the UTEC pulling timing.

i switched to stock and the problem went away.

so my apparent observations says that it is in fact not the same and possibly dependant on tube and fin vs bar and plate construction?

or maybe size?

or a combination of both.


I don't want to break any laws of physics here but it seems like this would make sense...one design being better than another for heatsoak purposes.

That being said I am really tempted to go v7 JDM STi since the size is comparable to ARC and the design is pretty proven since most of the sti I saw over there were running stock top mounts.

(nobody ran front mounts)

Heat soak IS the same. You had problems because you used the stock splitter. Bigger intercooler = bigger splitter or you are actually doing worse for wear as you aren't cooling off the whole thing.

FORGET bar/plate vs. tube/fin. Ignorant people argue this, read this:

heatsoak WILL vary with TMIC size. The bigger the TM, the longer it will take to "soak", and also the bigger the TM the longer it will take to un "'soak".

I posted this same statement in another thread a few days ago, and someone quickly wrote that I was wrong, bigger TMICs soak faster, etc.

Well, after looking at my IC temps over the last week and a half with my bigger top mount, I [continue to] agree with this statement, that bigger TMICs take longer to soak and unsoak.

don't think of it so much in terms of size or volume, think of it in terms of mass.

more mass = more thermal inertia. that's both good and bad. it's certainly different.
