An air/water intercooler should be completely separate from the engine's cooling system.

This is how Toyota did it.

very true! but i do recall some large trucks using the engine coolant to cool the intercooler...  would probably help a lot in colder climates though!

ive got an aaz and i put a mk3 tdi intercooler on and it made quite a difference. car is a lot more rev-able if that is even a word and im only boosting at about 12psi with no fuel mods other than a new lda pin. whilst the small cores may not be as efficient when ur stuck in traffic, they still do something when ur actually moving and for me it was well worth the money spent :)

A bit off the subject of water cooled intercoolers but here is my set up on a 81 Rabbit with a Saab Blackstone ic. It works great nice cool charge back to the intake.

It doesn't help that you're sucking in hot air though.

Nope no hot air it gets plenty of flow from the front of the car. I move the radiator over to make room for the ic.

You do have the timing belt covered now right? Scares me, but I live all around dirt roads and stones. Earlier this year I took out my grill with a dove. It ended up on the spark plugs of the 83 GTI with its head dangling right about where the belt would meet the IP  :o

Back to intercooling...

I plan to use the washer nozzle tank as the IC sprayer tank, the line now has a nozzle on it that will spray water on the intercooler when I want to, plus you could always put a small rad fan on the I/C that is pressure activated?

yea just buy one of those hobbs pressure switches off ebay.  totally adjustable too  :)  thing is at speed you don't really need it, so a temperature one is better, but more $$$.  rainbow electronics sells one that reads from 0c-120c, but i can't find their website anymore :(

All good info !!

What is your opinion on the cheap eBay intercooler kits ?
I dont see myself spending 750 for a brand name intercooler.
Woulsdlike to stay away from plastic end tank types if at all possible.
Also what is the relevence of single or dual core?

It's for mounting on a MKII chassis, the longer ones would fit great inside
the big bumper 90-92 style but I wonder about getting the piping back up to the
turbo with as little bends as possible.

Can fab up all my own stuff, no worries there.
Just need education from you guys,

Much thanks,

Hugh

I like how you have it set up, looks like it came like that.  I think it will really make a big difference though once it gets cooler air to begin with.  I had given the rain tray some thought too about putting the I/C in there to eliminate some tubing and supposedly less lag.  I'm sure somebody has done it on one of these Rabbits before.  That's where  the old Ram-Air muscle cars got their air from if it made any difference.  I'm sure something could be made to fit in there.
