I'm shooting for around 320whp at around 15psi in my '87 Turbo II. The turbo I'm running is a medium sized s5 hybrid. The intercooler core that I'm looking at measures 22"x7"x2.5".

I realize that it's not a *huge* core, but considering I'm on the stock TMIC right now, I figure it'll be a decent upgrade. Also, I'm running the stock RAD, so the 2.5" thickness should allow a little better airflow to the RAD. Not only that, the smaller size should reduce the need to cut out a lot the front bumpers back-side.

Oh yeah, and $100? I can't complain.

If you have an FC you can get the ebay 24 x 12 x3 and it fits easily with the same compromise you need for that intercooler (removing or cutting the bumper support.
It can also be had for 100 dollars

I did go with a bigger core. My Greddy piping is 2.75" dia., so I didn't want to go any smaller than that for the core inlet and outlet. So yeah, 24x12x3 FTW. Grand total of $134.

28x5.5x2.5 cost me 88 shipped............I'm running on the stock turbo though..........I think it will be plenty big:

here is another 5.5" tall IC....this one was stolen and I bought another one:

27x5.5x2.5:

does that size let you keep the stock bumper core?

you should get rid of your mechanical fan. electric is the way to go!

fastcarfreak

btw, typically the smaller the turbo, a more larger the intercooler is needed. It also depends on how much boost you plan to run.

Ok the bumper core is the inner plastic bumper which is the actuall stressed part if you hit something. I cannot tell from the picture if the car has the bumper core or not.

Madrx7racer

i already have an e-fan but not installed.....

Madrx7racer

if you trim the BUMPER support it will fit.......I juts removed mine....If you mount it differently you can keep the Bumper support....

I dunno man, the stock clutch-fan pulls a lot more air than most E-fans...

Madrx7racer

yes......but when I make my vented underbelly tray and my reverse vent hood i believe it will not be an issue

Madrx7racer

and the bumper core is THICK fiberglass....not plastic

slo

iTrader: (1)

Wrong or not I prefer to call it plastic.

I am also running around with no bumper core, which is something I am not totaly comfortable with. I plan to re-create one out of tubular steel, that can fit in front of the intercooler.

That's a pretty odd thing to say...

Uhmm FRP Fiber Re-Inforced Plastic ????

Maybe because technically it is a plastic

Think before you bag on somebody.

Madrx7racer

no, I actually thought it was all fiberglass....thanks for the new info.

Perhaps the reasoning is that a larger turbo is generally more efficient at higher boost/airflow? Correlating intercooler size to horsepower is probably more sensible.

Cheap isn't going to help.

Evil Aviator

Yes, I always thought the intercooler size depended on the loudness of the BOV and the color of the shift ****. Hmm.

That's a good point. For example, a 500hp NA V8 is going to need a much larger intercooler than a 400hp turbocharged 13B.

good to hear your finnaly going front mount erik

you might wana give the spearco IC's a shot they are smaller which is what I think your looking for but plenty thick.

I don't remember cutting any plastics that would make your skin itch after a couple of minutes; FG on the other hand...

Guess what happened when I trimmed the bumper?

The core is installed and for the short time I drove it, it made a VERY impressive difference. Much better boost response and low-end power. Didn't take it past 5k RPM's on the trial run.
