I like where this is going!

RX SE7EN · 11-07-2011, 11:45 PM

Started on the FMIC tonight. Used the greddy brackets to move the radiator, and making custom brackets and piping for my PFS large SMIC which is now going to be a FMIC.

How it used to look:

In Progress:

Getting the position right:

From below:

I'm going to run the piping a little different than how the usual FMIC kits run, it should look pretty cool.

I really want to switch to a slimmer fan setup so I have more room for some fresh air ducting to the air filter, anyone have any recommendations?

TORQUEFLO BABY!!!!!!

I should have a stock Cherokee fan that we could try, or something else OEM would be the way to go.... actually, I may have a spal too that you could use for mock up, we'll look when you come by on wed for some welding

reddozen · 11-08-2011, 01:34 PM

I'm loving the idea. I was wanting to twin charge my FC... hadn't gotten that far yet.

How's the M45 working out for you / going to work out for you? I would think that would be a little small. I have an M90 on the shelf that I was planning on using.

RX SE7EN · 11-08-2011, 03:40 PM

I've got an M62, should allow me to hit 500 (I hope)

Sweet, I'm going to try just cutting the plastic support (upper passenger side in front of the turbo) off and see if it still works ok. I have a feeling it'll be fine, there will still be 3 other 1" think arms holding the fan in place.

Last night i was researching slim fans, nothing flows even close to the stock ones (2700 CFM) unless I go over $150, which isn't worth it right now. We might need to get creative on the turbo inlet, not sure yet.

And I heard bad things about SPAL, didn't your last one fail too? That scares the crap outta me.

RX SE7EN · 11-08-2011, 03:44 PM

Oh, and you have finally won, I am in the process of ordering -16 AN bungs and fittings for the Rad.....

RX SE7EN · 11-08-2011, 10:01 PM

So I chopped off the support that was in the way, it's still extremely sturdy, so i don't think it'll be a problem. Now I have plenty of room.

Before:

After:

Of course, now the hardlines for the dual oil coolers are in the way. If you remember from a few pages ago, I had to convert the one that went from the driver side cooler to the rear of the block to a -10AN line in order to clear the supercharger bracket. I left all of the other ones stock in order to save money. Looks like I'll be making the rest of the lines match now (it's ok, I was planning on it anyway).
Here's a another pic, now with the oil cooler lines removed:

Notice all the space I have in front for the intercooler to be tilted forward slightly, alowing for softer bends on the piping. Don't worry, this will all be very well ducted.

Also removed my ABS to make room for the catch tank and new oil fill neck. These will share the turbo drain line.

Firewall is looking better already:

I'll be using Alex Rodriguez's nifty kit to run the new brake lines with proportioning valve.

helghast7 · 11-09-2011, 10:36 PM

badass, makin some great progress, cant wait to see her when shes done

RX SE7EN · 11-10-2011, 11:34 PM

Added a mounting tab to the intercooler for its test fit (only tacked on right now). It turned out pretty well, so now I'll add two more tabs to secure it in place.

Lots of room for piping, and it's slightly tilted so I won't need 90 degree entries into the cooler:

With the bumper on. The ductwork will connect it to the bottom of the radiator, and fresh air will go around the sides and directly into the radiator, with ducting to make it so it can't escape before it hits the radiator.

RX SE7EN · 11-10-2011, 11:44 PM

Also made progress on the plenum. Had the the top and a side welded on, have the other side cut already but wanted to test fit it first. Note the beautiful welds by TitaniumTT. (i left the side long on purpose in case i wanted to change the angle of the throttle body, i'll trim it off later on)

Installed, you can see it's really going to clean up the top of the engine, and at the same time give me more plenum volume and allow me to change the oil filter without removing it!

Not quite as much clearance between the bottom and the supercharger inlet as I'd like, so time to trim it down. This is why you test before welding it all up

Cut line:

This is the 1/2" plate that will be cut to make the flange for the 90mm throttle body. This will be welded to the front of the plenum and will have 4 holes drilled and tapped for mounting the throttle body. Also got a gasket to seal it up.

RX SE7EN · 11-12-2011, 09:24 AM

The build continues this weekend with new arrivals from Summit Racing

Whats inside?

A whole bunch of AN fittings, hose, and weld on bungs (steel and aluminum).
Sizes are:
-4 for catch can
-6 for coolant circulation connection between bottom of radiator and fill neck
-10 oil lines and oil fill neck (some will be nylon braided, and i got Stainless braided for the turbo drain which will be covered in black fireflex hose to protect it from the heat
-16 fancy radiator hoses

I have weld on bungs for all of that. And I also got a bunch of weld on NPT females for the new plenum, this way my AIT and meth nozzles will screw right in.

Also got a -4 check valve for the meth system. The pump has a built in one, but i wanted to ensure against boost leaks at 12psi when the pump isn't on yet.

RX SE7EN · 11-17-2011, 11:24 PM

Quite a few updates.

Radiator is done, just need to make some nice looking mounting brackets:

Found a date on it, but not a brand. Does anyone know what kind of radiators PFS used back in the day?

Mounted:

Room for the piping:

Room to get at the air filter:

RX SE7EN · 11-17-2011, 11:31 PM

Just about done with the manifold.

Welded the bottom plate on at the runners.

Which got it all nice and hot so I could bend it down:

Perfect fitment:

A piston doing it's job and providing support haha

Cut the throttle body flange:

Very glad that I bought the 6.5 amp saw

Flush on every side

Ready to cut:

RX SE7EN · 11-17-2011, 11:35 PM

Started cleaning up the throttle body and getting rid of stuff I don't need.

This isn't a Nissan:

I won't be having any coolant running through this:

Now just need to file it smooth.
