Guys am I the only one who gets enormous amounts of heat in my car from my motor setup?

Its almost unbearable when it gets hot out. I can't figure out where its coming from so I am assuming its through the firewall.

I may do heat barrier in the engine compartment at some point, its pretty damn uncomfortable..

Any other thoughts? I have an S14 with rb25det.

yeah I get the same thing, keep in mind we do sit infront of a turbo and exhaust manifold... 240's dont exactly have the best insulation...

yeah make sure your heatercore is set to cold to, it gets blow by and still lets heat out even if the fans are off. Thats what, windows down and removing the sunroof is for.

Dude my windows are never up. Sunroof is always open (unless its super sunny LOL).

I am going to do some searching and find out what products to use. I even found the floor of my trunk was hot by my muffler.

Time for some action. I want to do A/C on my car and there is no point if its super freaking hot from the firewall.

Ill check to make sure the heater core is close, I am almost 100% sure it is. It blows cooler air when the blower is on (I have to have the blower on).

Honestly I cannot remember about the heat shield. I do know its present under the car though.

No undercoat here man!
