Use some vacuum tubing, i know you have some laying around to make a little bushing. Might help some.

**** looks good to me! Nice work. Wondering if I could do something similar. Probably not though as I'll have a thicker radiator and need room for an 8 rib pulley and tensioners for the SC's.

I actually have a small rubber bushing pressed into the radiator mounting bracket. The screw that holds the radiator to the bracket goes through this bushing. Here is a zoomed image...

I have some room left over so if I have to upgrade to a Godspeed radiator for example I think it will fit. Not sure about room for supercharger pulleys and belts though

I'm not sure you will be able to fit the Godspeed. I truthfully think a 1" radiator would be a much better option for you. Possibly the coolradiator.com rad if its available or maybe a stock NB automatic radiator. They're slightly larger and all metal. Or possibly a koyo 33mm. Judging by how much you have already cut your radiator hose you have minimal room. I'll take better pictures showing how much room i have with the godspeed in stock location tomorrow if I can.

Should I get the cheap ebay fans or should i get some of the 11" SPALs you picked up?

Go to an O'Riley's ond pick up some of their slimline fans. I am currently running 2 12" fans, and have no issues with overheating with the stock radiator at idle.

Yeah I think you might be right. Cutting down the stock hose more would not work as it is pretty close to minimum right now. I would have to come up with one that had more of an s-shape to make it work. I agree the 1" radiator from coolradiator is a good idea. I have looked at that one before. I think someone else here runs one. Brain maybe?

The Spals are nice but they are not cheap as you know. The ones that siliconeintakes sell look very similar to the Spals, though the current draws (power consumption) IIRC are not as high. This could indicate they do not flow as much air all else being equal.

I do need to fabricate and install the shroud though as the car is definitely running warmer while cruising. I'll update the thread when I get it in place.

Nice install- good job taking advantage of the available vertical space up front.

Ben- I think it's almost as simple to drop the rad on the NA, IF you build some new rad brackets to hang on the OE hooks. For my rad, it's just a simple cradle that hangs on the OE rad hooks. I keep saying there's lots of vertical space available up there. My rad is way taller than the stock unit and the bottom is still above the bottom edge of the nose skin.

I had thought about that, but unfortunately, I have no welder

I don't remember what they cost. And my car was a NA. But when I heard the price of a new OEM fan. I bought the universal from Oriley's. Sold the car to my cousin. 3 yrs later it's still working great.

You can get the same fan oreilly sells on ebay for 1/2 the price. Or from siliconeintakes.com if you don't like ebay. You can also use discount code link987 at SI and get like 10% off.

Yeah, I found that out a little too late.

I needed the fans NOW so I just payed the price...guess thats what I get for waiting till the last minute to get them, but in my defense I didn't even mean to turbo my car the weekend I did, it just happened.

OK I just finished the first prototype of the cowl. This is the first time I have worked with sheet ABS but it turned out to be a good fabrication material and I am pleased with the results. It will function for sure, and looks decent.

Looks like it bends nicely as well. Did you have to heat it at all to bend it or just bend and let it spring into the static position after bending?

Looks like 1/8" from here.

Yep 1/8" ABS. I think that is about the right thickness to use here. 1/16" would probably not be stiff enough, and 1/4" would be overkill and harder to bend.

Basically I made a template out of cardboard by measuring, cutting, and fitting it in place. I then used that to make the pattern on the ABS. I cut it using a small battery powered circular saw with a fine tooth saw blade. It cuts easily. After that I heated it up with a heat gun and bent it using some boards as straight edges to bend against. It has to get pretty warm before it bends. Once it cools, the bends are sturdy. I drilled the holes for the IC hoses with a hole saw. I used a palm sander with 80 grit paper to clean up the edges. All together it took about 3 hours to fabricate which is not too bad.

that looked great. is there a reason you didn't go with something like this:

to save a bend or 2. thanks.

I looked at that one as well. That IC will also cover up more of the radiator. It could fit but will be tough with the a/c dryer. I think others here have made something like that work by mounting it off-center over to the left side of the car.

The two 90 deg reducing couplers at the IC were only $20 a piece so it was not a big deal. The additional pressure drop is negligible.
