Default Front mount intercooler fit?

Is there any room for a decent size front mount intercooler? I’m thinking of attempting a 5.3 single turbo build. I’ll be removing all air conditioning components. Thanks

I recommend meth / water injection. I have it and it works well.
Lowers the air temperature a lot.

Not really interested in running water/meth, have had great results with air to air intercoolers on other cars

What year? I have a front mount in my 85 and, while it is a very tight fit, you can get one in front of the condenser. Without air conditioning, you'd have "plenty" of room.

A few pictures of my 1984 during fabrication. The core is 600mm x 300mm x 100mm ( 24" x 12" x 4" ).

How big is your front mount?

Similar in size to the one Joby has. I'd measure it but the car is (still) at the body shop getting damage from a collision with a deer fixed.

@JoBy Joby that's interesting, your intercooler piping is routed very similar to how mine is. (Not like there are a ton of options with the very limited room in a C4...) Looks like 3" pipe? I'm planning on changing the path of the piping on the passenger side. I like how your looks there a lot better than how I did mine. Does your car still have the factory coolant overflow tank in the stock location?

Yes, but those pictures are over 16 years old.
Intercooler has 3" ports. Driver side to engine is 3". Pipe from turbo to intercooler increases from 2.5" to 3". I have bought my third tubro for the Corvette no, sizing up again. So I have to make a new pipe from turbo to intercooler.

I have installed a thicker all aluminum radiator and also lowered it to make room for a new radiator shroud with inlet ducting over the radiator. The Crossfire has a different radiator shroud with no space over the radiator and air ducting molded inte the hood.

Great pics, I was thinking the radiator on the first set of pics was very thin too, I figured you eventually upgraded
