Nissan 240z Heatercore #2-551

After looking around at http://www.pullmanford.com/heatercores/heatercoreinline.asp I found a Nissan 240z heatercore...this thing looks to be perfect for my setup. I'm hoping to find one cheap at a junkyard somewhere, because they're normally pretty expensive. What do you guys think? Single pass, 5.25 long x 6.625 wide, and 2.65" thick.

Would it be hard to make an acrylic (or something) shroud for this? And would a 120mm (either 25mm or 38mm thick) be enough to pull air through it?

I love 240z... Awesome classic car.

But anyways, from the picture it doesnt look like a single pass but i might be wrong because the picture isnt that clear... Looks like you could use just about anything to make a shourd for that. sheet metal, sheet plastic, looks like tupperware would work as well

Cut the in/out -lets so they are straight and dont kill your flow.

So it being 2.65 won't make it too restrictive, will it?

Also 240sx...if that isn't single pass, what else could it be? How would the water go through?

double pass.... Its gotta make a "U" to come out...

erm.. looks strange.
don't think its a single pass either, but gotta see the other side
looks a lot of passes, lol

double pass.... Its gotta make a "U" to come out...

but that isn't 'that restrictive right? mine does the u too

 

[ILikeMy240sx]

Double pass is not restrictive... Its just that single pass even LESS restrictive than double pass. U is good

Hmm...well if it's not single pass, it's not worth the hassle and possible price. Guess I'll just go with a Chevette then...sigh.

That 2-551 looks like a single pass to me. Here's another photo of it:

I think if it was a singple pass, the outlet and the inlet would be on the opposite side (meaning left and rignt not top and bottom)...

I dunno.. the more i look at it the more i think it would be a multi-pass...

1 pass is one trip through the "core;" the narrow finned area. The header (or tank) on the top connects all of the channels on that end. Likewise with the tank on the bottom. With one fitting on each, you have a single pass core. A 2-pass core has fittings on each of two half-size tanks on the same side. Water enters one fitting (and tank) travels through that half of the core to the full-length tank on the bottom, and then back up through the core to the other mini-tank on top. See the Chevette core for an example.

I think omaticrail is right...I don't see how it would be multi-pass. How would the tubing run? In relation the picture, the water is going up/down, not laterally.

Unfortunately, I don't think I can find a place to get this heatercore...no junkyards around here have one.

Hmmm ok you sound right. So basically like this?

More like this, I think...
