been looking for someone who knows of it, or has experience with it. Right now I've got a (mostly) stock '90 TurboII and I'm getting kind of sick of the horrid heat soak that I get with my stock TMIC all the time.

Is it a good intercooler (it looks huge, not that huge is necessarily better, but for this application is it ok?) Will it work good up to about 400, maybe 450? I heard that's its limit. Also, will it be fine with me and my stock car? I'm running only 5.5 lbs of boost (stupid duty solenoid).

*bump* (thanks for the help...)

By the way.. did they reset the servers? I swear I bumped this thing yesterday.

What's *bump* mean. I'm kinda new to forums

it moves the thread back to the top, so hopefully someone won't be worthless and just read it and not respond.

i higly doubt that you will make 400hp on that IC.
go get an isuzu NPR IC for a few hundred bucks ($200) and make something much better if you do not feel like spending much money.
here is a pic of a 91 convetable with an FD motor with a tII front cover. the IC is right up front, and mouted upsidedown.

what's bad about the intercooler by the way? I've read up on intercoolers, but there's no way to really tell without knowing the specs on them (which nobody provides)

aw damn,
my post was directed tword you thinking that you were refering to the stock IC of an FC.
i didnt even see the title to this thread. i clicked it by accident, and was thinking you were refering to a TII ic.
sorry about that. i would guess that IC is big enough.

i am not familiar with the IC from the GTR, but here is some info on *other* IC people tend to use inplace of "kits"
hope this helps
The NPR IC(Med): at 329cfm and 290°F on the inlet side of the IC, the
pressure
drop is 0.09psi. The outlet temp is 130°F, heat rejected is 55553
BTU/hr, and
the calculated heat exchange area is 1404 square inches.

Starion IC : (the bigger one) at 324cfm and 292°F on the inlet side of
the
IC, the pressure drop is 0.29psi. The outlet temp is 139°F, heat
rejected is
52287 BTU/hr, and the calculated heat exchange area is 1217 square
inches.

Saab 9000 IC: at 332cfm and 295°F on the inlet side of the IC, the
pressure
drop is 0.81psi. The outlet temp is 123°F, heat rejected is 60350
BTU/hr, and
the calculated heat exchange area is 1602 square inches.

Volvo IC: at 331cfm and 293°F on the inlet side of the IC, the pressure
drop
is 0.55psi. The outlet temp is 126°F, heat rejected is 58809 BTU/hr,
and the
calculated heat exchange area is 1539 square inches

how's the stock TurboII intercooler stack up to these?

3rdGen7

XS Engineering sells the GTR Intercoolers.. Quite a few of the 9 sec Hondas use them.

If you want it bad enough and offer me enough, I'll sell you the one off my R34

Then NPR Intercooler is used one 1000hm race cars, id say uts a tad better than the stock FC intercooler.

GTR Skyline intercoolers are not much use if you are chasing oiver 450HP.
will be fine on near stock or lowish boost 2nd Gen for sure.
i sponsor the SDU club here in NZ and there is a lot of talk about this.

So yes, fine for your application, but just joining 2 x 2nd gen ICs together would be just as good since you aren't going for big HP and will be cheaper.

80-CU.IN.T

The Skyline GTR intercooler core measures 24" X 11" X 3" (HUGE). The fin design is tight meaning that air flowing through it ( front to back) for cooling might be hindered at lower speeds. I am using this core in my 3rd. Gen. because is came with one of my favorite words (CHEAP). I got mine for $210 US. I can't say where because I promised.

I have no idea of what people are saying about supporting only 450 hp. That would have no merit on it. The core will flow as much air as you want to push through it (as will any core design), it has a huge frontal surface area for cooling and the welds on my core look fine. The interior passages are very functional in design for heat transfer ( the same design has been around for a very long time and most intercoolers are designed this way.) As for pressure drop I have not done any testing on it. My end tank design and intercooler plumbing & length should have more of an affect than the core design. (33 sq. in. of surface area for my turbo to blow through is (VERY BIG).) I don't think it will cause any significant back pressure.

If I were to do it again I would use the new APEX'i core. I don't know it's name or part number off hand. It is the same size but the tube and fin design are different. Revolutionary in design in my opinion for letting the air from the front of your car pass through it at lower speeds. There is a company in Northern California that is currently marketing one for the 3rd. Gen.. I personally don't like the way they made thier end tanks but it is the only way unless you really want to cut up the front of your car. I did and re-welded.

If you are looking for the new APEX'i intercooler core check out their websight. Good luck and let us know on hat you finally decide.
