They are different sizes and
different construction. Ones included with a bunch of shiny piping
and blue connectors and clamps.

Will someone take a look and tell me what in there opinion
is good for my application. Not them say what CFM there rated
at.

Thanks Joe D.

This last one has all the piping included ... I like this one its kind of small
though probly ok. I dont really know.

I would imagine that you will run into the same problem with all four... the inlet and outlet placement, with the width of the IC and the bends needed coming off those "nipples" you will most likely run in to clearence issues. Just what I would guess by looking at them.

Yea Id have to do what RC did to his. He was able to form the tubing
into a square useing a block of wood and a soft mallet..

Rocco posted this site.
http://www.siliconeintakes.com/stpg.php?page_id=intercooler_pipe_fabrication
There everything in the piping
is found though its all silicone tubing theres straight couplers
and elbows and blow off valves. I just need to find straight pieces of aluminum piping. I wouldnt want to use all silicone tubing.

Cut off the inlet and outlets and moved
them to the top so theres no critical
bends taking up space that isnt much
of. Pics of his work here.

Ok so a colder inlet charge is better more dense and less
chance of detnanation.As are ambiant temperatures. I was thinking a intercooler box/w
dry ice. Since Im not running any ECU's the
untable (different temp.)charge coming out would not
mess with any fuel delivery sys. on board.
It would have to be a specially insulated box to
make the dry ice last longer because when dry
ice comes into contact with hot metal it turns into a gas.
Its not a new idea & has been done before. Of course
with increased combustion comes increased heat thus requiring
a upgraded cooling sys.

Hers a site that does it.
http://www.are.com.au/Big%20HP/Dry%20Ice%20race%20cooling.htm

Heres simple site giving basics on why install a intercooler
and why boost drops when its done. Whats it mean?
http://www.well.com/~mosk/intercooler.htm

When all said and done its time to bring on the boost.

Talked to a head and block machine/aluminum steel welding
shop today on my way home.. He couldnt quote me on a price
as I explained how I was planning on doing all the prep for
moving the inlet/outlet to the top on a intercooler. He did
it was very doable & to bring it in when ready and he wouldnt
jab/stick me.

Avoid tube and fin designs. Bar and plate designs drop MUCH more heat and offer MUCH less restriction (turbo lag will be less with bar/plate). Costs you more, but worth it if you're doing all of the hard work to install it in the first place.

If you can handle the fabrication, I would suggest going with an air/water unit. People don't seem to be into them much on here and I'm not sure why. I have one on my 301 whp 320 wtq Mazdaspeed 3 and see boost temps about 15 degrees above ambient most days unless it's WOT under heavy boost (20+ psi). The air/water systems I've seen on this site all seem to have undersized heat exchangers for one, perhaps that's why people here haven't jumped on board??? Not sure.

Unless the IC is fitted to a boat the correct description is "air to water to air". Clearly this involves TWO heat exchangers each with respective losses in efficiency that will compound. Pump, controller, hoses, etc all add to the weight and complexity. Although they do have a place in restricted access applications there is a valid reason why they are not popular and some members here have removed/ replaced them with air/air.

The cold ice/ dry ice box may have a valid use in drag cars but is hardly practical on the street.

Joe, have a good read through Maximum Boost (Corky Bell) particularly the IC section. There is a D/L link here somewhere posted by raceboy. Then plan the system first with pipe routes, etc. Will differ with application especially CIS and placement. Although my set up works well it was designed to suit the SC, TB location. Would surely be different if used with stock NA or 931 CIS.

[leadfoot]

FYI:
factors governing efficient cooling and operating temps are affected by a few things like;
size and placement of the intercooler ,
oil cooling,
radiator size/efficiency,
ducting of air in and out of the engine bay.

balancing these out can often yeild better results than to focus soley on one particular item.

an oil cooler will dramatically help lower heat soak and operating temps of an engine. oil tends to hold it's heat more than water. i.e having a small oil cooler means you can take the load off a radiator...

for piping look here

Would this intercooler fit? I think this is more of the style you should look for.

You know Im cash tight. It looks to small & again to explain
my 1st statement it cost twice as much. Im gonna look
local theres performane shops in sertain areas for
ricers and street customs. I could go used though
dont want to. Maybe I can find what e-bays selling
locally and skip shipping.

It would be ideal if you can find a single ended IC like Rocco posted, but in a more suitable size. Although it would work well anyway with near stock boost. A larger frontal area is usually more effective than a deeper core, for the equivalent volume.

The cost is not unreasonable unless your`e going to China anyway and have a good baggage allowance. Have you considered the additional cost of welding up a modded double ended IC as well as the IC and shipping?

Don`t you have a NA? If you`re fitting a 931 motor, CSI, drivetrain, whatever, the cost of an IC and shipping is a negligible percentage of the conversion. Honestly, if you haven`t spare money to burn your car may well be of the road for a very long time. Not picking onya Joe or anything, just see what other guys have done and spent on their boosted NAs. Much more cost than just running a NA.
