Intercooler in an FSJ sporting a 4BTA

Correction. The core is 2" thick, 25" wide, 10" high. There is just enough room to mount the AC condenser in front of it. And if you set the condenser at the same angle as the front sheetmetal, you could squeeze an oil cooler in there too.

just a little small but it will work just fine. Nice fit! Hankrod

Definitely not the solution if one is looking to hop up the engine a good amount. The Isuzu didn't have an intercooler from the factory, so I figured this would be a step in the right direction

Hi Zack, I have the answer from ' Maximum Boost' by Corky Bell. Basically for every 500 cfm of air flow you will need 25 sq. in. of intercooler core flow area. Now at 14.7 psi of boost a engine can double its displacement flow. So if my 407 can flow 1400 cfm @ 14.7 psi it will need 70.65 Sq. in. of flow area. Many more veriables involved but thats about it. Hankrod

Ok, I understand what you are saying here, but where did you get the 1400 CFM #? The calc I listed above for CFM has your engine coming out with a less (600 CFM) unless I did something wrong??? I didn't take boost into account.

I was going to use an intercooler out of a Dodge Sprinter van:

It fit in between the outer facia and the inner sheetmetal. It is rather thin, maybe an inch thick, but spans the entire opening. The 90* turns are part of the intercooler itself. It has to be mounted low to clear the hood latch.

Pete,
I like the ends on that intercooler. Only prob I see is squeezing the outlet between the inner fender and the rad support. That is why I did mine both up high, I didn't want to have to mess with the inner fender. Good find on the sprinter van intercooler

It is definitely tight to the inner fender. I think I can get away with just trimming the flange of the fender. If the hook for the hood was removed, then it could be mounted quite a bit higher and completely avoid the fenders.

I was thinking that too, if I could get rid of the hood hook, the intercooler I got could be 4-5" taller and cool more air. But I didn't want to mess with the original hood hook and I'm not a big fan of hood pins...

Thanks for all the pics Elliot and Hankrod. What are all the electronics for by the air intake?

Wide band 02 sensor interface, throttle position sensor, electronic boost controller/wastegate solenoid, and map sensor. Hankrod

On the contrary Dusty. I would still be sucking my diesel thumb if it weren't for you. You have helped me out tremendously. I really appreciate all the stupid questions of mine you had to answer…”Where does the fuel line go…” “Wait, there’s no distributor, WiTF do you do for a tach…” Stuff like that. Thanks again man,

Zack
