1st gen intercooler into N/Ic 1st gen
1st gen intercooler into N/Ic 1st gen
I finaly got all my parts for an intercooler install and decided to to a little write up on it.
With this install you WILL NOT be able to retain you're A/C condensor also with this install I flipped the I/C upsidedown
Tools you'll need
Socket set and rachet with a few extensions,a couple screw drivers,drill with assorted bits, sawzall wit a sharp blade, a sharpie, and a tape measure
Parts you will need
1st gen intercooler,1st gen piping, 8 2 1/2" t-bolt clamps or constant torq clamps, 1 2 1/2" v-band clamp, 1 90* v-band elbow, and 4 2 1/2" hump hose boots
First start by removng the Headlight bezels, grille insert, outer grill shell and lower filler panel

Next remove the radiator and A/C condensor if equipped

Now measure 7" down from the bottom side of top of the core support and make a mark, now measure 5 1/4" down from that mark and make another mark, now measure 3 1/2" over from the radiator opening in the core support and make a mark, and repeat on the other side of the support

Once you have your core support cuts laid out you can go ahead and fire up the sawzall and start hacking

Some additional trimming may be required
Now that you have your holes cut in you're core support you can go ahead and and start fitting you intercooler

Now establish where you need to drill your mounting holes (I just held the cooler where it looked centered and marked it with a sharpie) once this is done you can go ahead and drill the holes

You can now measure the space between the core support and the mounting tabs of the cooler, make a note of this measurment and measure the other side, make a note, now you can go cut you're spacers out of some pipe or whatever you got layin around(my measurements were 1 13/16 on the pass side and 1 1/2 on the drivers side
Once you get you're spacers cut you can bolt the cooler in place( remember to put some thin strips of rubber between the cooler and the core support)
I used some 3/8 bolts 3 1/2" long and used fender washers.


Now you can hook up all you're plumbing


Next you will have to trim the radiator mount to clear the inlet and outlet of the cooler
After this is done put the radiator back in the truck
I will post more tomorow after I trim the lower filler panel and get the grille installed in the truck

I haven't got the rag back together yet,waitin on parts
The reason I used the first gen I/C was cause one I already had it and two I'm tryin not to hack the heck out of the grill insert

I would add that if you haven't done put the tab in for the killer dowel pin this would be a good time to do it. That is my plan when I do this swap as I have most the parts for it minus an intercooler.

I got the grille and every thing put back together today
This is what I had to do
I trimmed the lower filler panel to clear the cooler and to get more air through it


I then installed the outer grille shell

Next you'll have to trim the back of the grille insert(I ended up cutting a lot more than I wanted to but I guess when I do a PS I/C I'll have enough room)


I'll probably end up making some stainless steel inserts for the grill so it'll look a little better

Driving Impresions
I noticed EGT's dropped 50* at idle, it dropped 100* at cruiseing speed and dropped 200* at WOT
I also noticed a 10 psi drop in boost but later discovered a small boost leak in one of the cheesy factory boots, I will report new results after Iget some new silicone boots on the old truck
On the test drive I saw a max boost pressure of 36PSI and a max EGT of 1250 degrees, and the climb there was a lot slower
All in all I'm very pleased with my install and would recomend it to anyone with a N/IC truck that can live without A/C

Well with as much as I trimmed off the grille I could probly fit the condensor back in, which I might do, or you could mount the condensor somewhere else.
I have also heard the factory intercooled trucks had a thinner condensor you could use also.
Is there any truth to this?
