Large NPR IC -- Too big?!
Hey,
I may be able to get a good deal on a large Isuzu NPR Intercooler. I've measured one and it looks like i may be able to shoehorn it into the front of my TII (it'd probably have to go upside down). Is this IC going to work OK for me? I realize that the small NPR intercooler may work a bit better, but I haven't been able to find one around here (anybody know which NPR those came out of?)
So, will it work, or am i insane?
It measures like 16.5" x 26-27 (the FC has 26" up front to work with, so i'd need to get a bit creative.
Thanks!,
Manolis

Felix Wankel: Right now it's the stock S5 turbo, and I hope to have a 60-1 on there by the end of summer 
hypntyz7: I assume that's the Large NPR IC then? How is it working for you (pressure drop, etc etc.)? Looks damned good up there
edit -- Those are stunning wheels hypntyz7, what are they? Sweet lookin'

i have one installed. 60-1. got to www.wickedrotary.freeservers.com
you cannot use it with your stock turbo. way to small. i am at full boost by 3500 with a .96 rear.

HN..hows the TII COsmo??..i need help tuning my E6K once i drop the motor in. Still have the same phone #??.
PISTON EATER. If you are not using the under tray you can install it upside down. I was gonna do that to my small NPR IC but ended up having it customized. The big NPR IC is very huge and you dont want to use it on a stock turbo. YOu will have a bigtime turbo lag.

UMMM actually Hypntyz has the small NPR. I know, I sold it to him. But for those of you wondering, the large one is HUGE. I think probably a little too big, plus it only flows 13 cfm more than the little ones. I have had both, and I think that the small one is better. The big one would be a PITA to fit and is twice the size of the little one. Plus it's ugly and flows less than 10% more. I bet the pressure drop is larger too. All in all, I would say go with the little NPR, which is still pretty big.

Im going to go with TurboGXL on this one, and say that thing is way too much of a monster, and most of its surface area is wasted. Id stick with a small NPR intercooler. The lag will kill you on a stock turbo.
Man, thats just too big....

I was selling them like crazy for $270 shipped but I sold the dozen or so I had QUICK!
The core dimensions of the small NPR are 19in x 2 in x 8.5 in. With 2 in outlet/inlets. Overall, about 31 in length by 11 in height. IIRC
The flow rate is like 129 cfm, with a 55000 btu heat reduction, pressure drop of .4 psi. Inlet temp of 240*F outlet temp of 160* F.

the benefit of the large one is ease of install and greater cooling than the smaller unit. the large one cannot be used on the stock turbo. i was using the large one with the stock cosmo twins and had no lag problems, sequentially or later on when i converted to non-sequential. now i have a 60-1 with a .96 exhaust, equall length tubular and have no substancially greater lag than stock.
