Large NPR intercooler piping

Anyone using a large NPR intercooler with a stock location throttle body? I'm curious what piping and couplers you used to make the connection from the intercooler to the throttle body. I have a fabricated 120 upper that i have been having a lot of issues with cracking at the welds. I'd like to switch to a gutted stock upper intake to solve this and a couple other issues.

I've seen it with SVOs, Mustangs, and T-birds, but they have a lot more room between the radiator and the front of the engine and their setup won't work.

I am running that setup now.

2.25 x 3 90° silicone at the TB
2' aluminum tube 90°
3" straight silicone coupler
a 4"ish piece of 3"aluminum tube
3" silicone 90° from there to the IC

It gives about 3/4" of clearance between the tubing and the aalternator pulley. I am only running one belt...

Thanks,
That's a huge help. I'm wondering if I should do 3" or 2.5". 2.5" would probably offer a little more clearance. I suppose I could see how difficult it would be to move the engine back with the Chuck mounts I am using to offer up a little more clearance.

The outlet on the NPR is 2.75, did you just clamp down on the 3" elbow?

I just checked. The elbow at the intercooler is a 3" × 2.75" 90°.

I recently posted this in the "Junkyard Shopping List" thread...

'03 - 11 Saab 9-3 Turbo
- Top air-charge hose - 2.75" w/ 90-degree elbow to 2" - Saab p/n 12785081 (Might be useful when using NPR Intercooler)

This is the big NPR with a 90° intake. We are making 90° intakes again if you want to go this route http://www.merkurdepot.com

Is anyone running an NPR with stock headlights? I've always wondered if it would fit OK with the stock inner light brackets still there...

I have the stock head lights and large NPR IC, no problems right now, but I will put the mustang head lights back on the car very soon and I think it'll be ok too.

What radiator are you using with the intercooler?

I think that shorty radiator is probably enough to keep the car cool all times of the year??? Considering they never really get too hot, stock, do they?

Another question I had, could one of you guys with the NPR I/C post a picture of the part number on the IC? Usually says Tokyo Radiator, correct?

Do you guys with this combo still have the front and rear fan, A/C?

Not trying to hijack anyone's thread, but what year mustang lights? I could definetly use some better headlights..

Guys in blazing AZ summer heat report cooler summer temps with the shorty rad vs the stock rad. :cheers

The big NPR IC takes up the same real estate that the AC condenser and front fan do, so those have to go

Sounds good Mike!
I just need a part number off the NPR I/C.
